1.1.1.1. WHY USE DRUPAL?WHY USE DRUPAL?WHY USE DRUPAL?WHY USE DRUPAL?
Drupal is a free and open source content management system (CMS) written in PHP and
distributed under the GNU General Public License. It is used as a back-end system for over 1% of
all websites worldwide ranging from personal blogs to corporate, political, and government sites
including whitehouse.gov and data.gov.uk.It is also used for knowledge management and business
collaboration.
The standard release of Drupal, known as Drupal core, contains basic features common to CMS.
These include user account registration and maintenance, menu management, RSS-feeds, page
layout customization, and system administration. The Drupal core installation can be used as a
brochureware website, a single- or multi-user blog, an Internet forum, or a community website
providing for user-generated content.
Over 7000 free community-contributed addons, known as contrib modules, are available to alter
and extend Drupal's core capabilities and add new features or customize Drupal's behavior and
appearance. Because of this plug-in extensibility and modular design, Drupal is sometimes
described as a content management framework.Drupal is also described as a web application
framework, as it meets the generally accepted feature requirements for such frameworks.
Although Drupal offers a sophisticated programming interface for developers, no programming
skills are required for basic website installation and administration.
Drupal runs on any computing platform that supports both a web server capable of running PHP
4.4.0+ (including Apache, IIS, Lighttpd, and nginx) and a database (such as MySQL, PostgreSQL
or SQLite) to store content and settings. Drupal 7 requires PHP 5.2 or higher.

1.11.11.11.1 Drupal OverviewDrupal OverviewDrupal OverviewDrupal Overview
Design is driven by the need to balance flexibility and simplicity. If a system is too simple, it can
only be used for a single purpose - but if it is too flexible, it may be too difficult for new users to
learn.
Drupal bridge conflicting goals by providing its users with the tools they need to make their own
content management solution, while still providing some prebuilt components to help them get
started. Thus, it can be described both as a content management system (CMS) and a content
management framework (CMF) - one system which strives to have the strengths of both, without
their deficiencies.

Most CMS are like a toy boat or toy truck - specific assumptions have been made about their use,
assumptions it would be hard for you to override. Frameworks, on the other hand, provide you
with raw materials only - you need to know a programming language, and have a clear design
vision, to put them together.
Drupal is set of building blocks. Building blocks are already created- in the form of contributed
modules - that you need to create a site that suits your needs, whether that is a news site, an online
store, a social network, blog, wiki, or something else altogether.
Drupal core, and the thousands of contributed modules that build on it, require an initial
investment to learn, but mastering the Drupal way is immensely rewarding. Drupal's passionate
community is a testament to its power to liberate site builders from the simplicity/flexibility
dilemma.
How Drupal Works?How Drupal Works?How Drupal Works?How Drupal Works?
People often think of a website as a collection of static pages, with some functions (like a blog,
facebook, twitter, RSS News Feed etc) around the pages. At the time of maintenance there
emerges a need of structured tree, nodes path defined websites.
Drupal, on the other hand, treats different content types as: a node. Static pages, blog posts, and
news items (some possible node types) are all stored in the same way, and the site's navigation
structure is designed separately by editing menus, views – is the content view, and blocks –
supplementary content which is linked to this main content somehow.
It’s a lot like the separation you find in standards-compliant page coding like XHTML or XML
provides the structure of the data, while corresponding style sheets applies the presentation of the
data. Nodes hold the structured information pertaining to a blog post (such as title, content, author,
date) or a news item (title, content, go-live date, take-down date), while the menu system, as well as
taxonomy (tagging of content) and views, create the information architecture. Finally, the theme
system, along with display modules like Panels, controls how all this looks to site visitors.
As there are different layers, there can be completely different presentation and navigation
schemes per user, in other words each user can customize their own features, navigations, etc.
What are NodesWhat are NodesWhat are NodesWhat are Nodes
Node is core to provide the flexibility in Drupal.
We don't talk about "nodes" every day, but since they are at the heart of Drupal's design, they
deserve further investigation. At its most basic, a node is a set of related information. When you
create a new blog post, you are not only defining its body text, but also its title, content, author link,
creation date, taxonomy (tags), etc. Some of these elements will be shown by the theme layer when
the node is displayed. Others are meta-data that control when the node will show up at all - such as
taxonomy or publishing status.
Since each item of content is stored as a node, and contains the same basic information, each can
be handled in a standard way by both Drupal core and contributed modules. This allows site
builders to choose exactly where they want content to show up, and exactly how they want it to
look in each case. Most of a Drupal site builder's time is spent defining what kinds of information

you want to store in your nodes, and configuring the structures (menus, taxonomy trees, views,
panels) in which to display them.
As suggested before, you aren't limited to a single way of presenting your site's content. You can
define as many navigation schemes, custom themes ("skins" for the site), blocks, and feature sets as
there are distinct audiences for your site.
Comments are second-class citizens in Drupal compared to nodes, but they also illustrate the
Drupal way. Comments aren’t just part of the blog system, since there isn't a separate "blog system."
Comments can be enabled on any node type you choose - blog posts, news items, book pages and
any other you may create.
Collaborative at the coreCollaborative at the coreCollaborative at the coreCollaborative at the core
Creating an informational website that broadcasts from “one to many” is something that most
CMSs do right out of the box. However, where Drupal really shines is when you want to empower
site users to create content, and connect with each other - moving from "one to many" to "many to
many."
With some CMS's, you can set up a blog, and you can install plugins to handle having a
community of users, but what happens when you want to give individual blogs to each of your
users, sorting their contents so that they can be displayed individually with their own skins, while
also generating cross-blog topical digests, top five lists, and links out to elaborate, customized user
profiles? What if you want to also integrate that in with forums, a wiki-like environment, and give
each user their own gallery of taggable photos?
Drupal is designed from the ground up so site builders can delegate content creation, and even site
administration, to users. All you have to do is define who gets to do what on your site (through user
permissions), and then you can start collaborating.
Get started quickly, customize extensivelyGet started quickly, customize extensivelyGet started quickly, customize extensivelyGet started quickly, customize extensively
Drupal's flexibility is incredible, but installing it is surprisingly easy. With a simple FTP upload and
a few short web-based configuration questions, you can connect with your database and have your
first Drupal site up and running within an hour.
Pick one of the included themes, and just start adding content. Do you want to have visitors log in?
Switch authentication on or off. Want to switch on some of the included tools? Turn on forums;
enable commenting on node types; turn on the book module for wiki-like collaboration; create
forums and polls; use taxonomy to give site content structured, hierarchical categorization or free-
form tagging.
Do you want your own skin applied to the site? Drupal's theme system uses tiny snippets of PHP
that you can insert into the appropriate spots in your design to replace your placeholder text with
dynamic content. Drupal’s generated markup is clean, standards-compliant XHTML. No old-
school tables.
1.21.21.21.2 The Drupal flowThe Drupal flowThe Drupal flowThe Drupal flow
If you want to go deeper with Drupal, you should understand how information flows between the
system's layers. There are five main layers to consider

At the base of the system is the collection of nodes—the data pool. Before anything can be
displayed on the site, it must be input as data.
The next layer up is where modules live. Modules are functional plug-ins that are either part of
the Drupal core (they ship with Drupal) or they are contributed items that have been created
by members of the Drupal community. Modules build on Drupal's core functionality, allowing
you to customize the data items (fields) on your node types; set up e-commerce;
programmatically sorting and display of content (custom output controlled by filters you
define); and more. There are thousands of different options within the fast-growing repository
of contributed Drupal modules. They represent the innovation and collaborative effort of
everyone from individuals to large corporations.
At the next layer, we find blocks and menus. Blocks often provide the output from a module or
can be created to display whatever you want, and then can be placed in various spots in your
template (theme) layout. Blocks can be configured to output in various ways, as well as only
showing on certain defined pages, or only for certain defined users.
Next are user permissions. This is where settings are configured to determine what different
kinds of users are allow to do and see. Permissions are defined for various roles, and in turn,
users are assigned to these roles in order to grant them the defined permissions.
On the top layer is the site theme (the "skin"). This is made up predominantly of XHTML and
CSS, with some PHP variables intermixed, so Drupal-generated content can go in the
appropriate spots. Also included with each theme is a set of functions that can be used to
override standard functions in the modules in order to provide complete control over how the
modules generate their markup at output time. Templates can also be assigned on-the-fly based
on user permissions.

Content Management System (CMS)Content Management System (CMS)Content Management System (CMS)Content Management System (CMS)
A content management system (CMS) is the Collection of Procedures used to manage work flow
in a collaborative environment. These procedures can be manual or computer-based. The
procedures are designed to do the following
Allow for a large number of people to contribute to and share stored data
Control access to data, based on user roles (defining which information users or user groups
can view, edit, publish, etc.)
Aid in easy storage and retrieval of data
Reduce repetitive duplicate input
Improve the ease of report writing
Improve communication between users
In a CMS, data can be defined as nearly anything: documents, movies, pictures, phone numbers,
scientific data, and so forth. CMSs are frequently used for storing, controlling, revising,
semantically enriching, and publishing documentation. Serving as a central repository, the CMS
increases the version level of new updates to an already existing file. Version control is one of the
primary advantages of a CMS.
Types of CMSTypes of CMSTypes of CMSTypes of CMS
Enterprise content management
An enterprise content management system (ECM) is content, documents, details and records
related to the organizational processes of an enterprise. The purpose and result is to manage the
organization's unstructured information content, with all its diversity of format and location. The
system manages the content related commercial organizations
Web content management systems
A web content management (WCM) system is a CMS designed to simplify the publication of web
content to web sites and mobile devices—in particular, allowing content creators to submit content
without requiring technical knowledge of HTML or the uploading of files. Several web-based
content management systems exist both in the Open Source and commercial domains.
Web group content management systems
The web group content management system (mostly known as GMS) is very similar to the WCM,
with the main difference being the fulfillment of some specific requirements. These requirements
aim to satisfy the needs of groups or small organizations that often have difficulty managing their
online image, communicate with their members, plan events, set schedules and assign tasks to
internal projects. Typically these tasks are distributed by different tools and the GMS unifies them
into one.

Component content management system
In a component content management system, the content is stored and managed at the sub-
document (or component) level for greater content reuse.
Drupal ConceptsDrupal ConceptsDrupal ConceptsDrupal Concepts
Module
A module extends Drupal features and/or functionality. Core modules are those included with the
main download of Drupal, and you can turn on their functionality without installing additional
software. User modules can be created and installed; this requires a thorough understanding of
Drupal, PHP programming, and Drupal's module API.
User, Permission, Role
Every visitor to your site, whether authorized or anonymous, is considered a user to Drupal. Each
user has a numeric user ID, and non-anonymous users will have proper credentials of user id and
email, etc. Other information can also be associated with users by modules; for instance, if you use
the core Profile module, you can define user profile fields to be associated with each user.
Anonymous users have a user ID of zero (0). The user with user ID one (1), which is the user
account you create when you install Drupal, is special: that user has permission to do absolutely
everything on the site.
Other users on site can be assigned permissions via roles. To do this, first need to create a role,
which you might call "Content editor" or "Member". Next, you will assign permissions to that role,
to tell Drupal what that role can and can't do on the site. Finally, you will grant certain users on
your site your new role, which will mean that when those users are logged in, Drupal will let them
do the actions you gave that role permission to do.
You can also assign permissions for the special built-in roles of "anonymous user" (a user who is
not logged in) and "authenticated user" (a user who is logged in, with no special role assignments).
Drupal permissions are quite flexible -- you are allowed to assign permission for any task to any
role, depending on the needs of your site.
Node
A node in Drupal is the generic term for a piece of content on your web site. Some examples of
nodes
Pages in books
Discussion topics in forums
Entries in blogs
News article stories
Each node on your site has a Content Type. It also has a Node ID, a Title, a creation date, an
author (a user on the site), a Body (which may be ignored/omitted for some content types), and
some other properties. By using modules such as the contributed Content Construction Kit

(CCK) module, the core Taxonomy module, and the contributed Location module, you can add
fields and other properties to your nodes.
Comment
Comments are another type of content you can have on your site. Each comment is a typically
small piece of content that a user submits, attached to a particular node. For example, each piece
of discussion attached to a particular forum topic node is a comment.
Taxonomy
Drupal has a system for classifying content, which is known as taxonomy and implemented in the
core Taxonomy module. You can define your own vocabularies (groups of taxonomy terms), and
add terms to each vocabulary. Vocabularies can be flat or hierarchical, can allow single or multiple
selection, and can also be "free tagging". Each vocabulary can then be attached to one or more
content types, and in this way, nodes on your site can be grouped into categories, tagged, or
classified in any way you choose.
Database
Drupal stores information in a database; each type of information has its own database table. For
instance, the basic information about the nodes of your site is stored in the Node table, and if you
use the CCK module to add fields to your nodes, the field information is stored in separate tables.
Comments and Users also have their own database tables, and roles, permissions, and other
settings are also stored in database tables.
Path
When you visit a URL within your Drupal site, the part of the URL after your base site address is
known as the path. When you visit a path in your Drupal site, Drupal figures out what information
should be sent to your browser, via one or more database queries. Generally, Drupal allows each
module you have enabled on your site to define paths that the module will be responsible for, and
when you choose to visit a particular path, Drupal asks the module what should be displayed on
the page.
Theme
The theme controls how your site is displayed, including the graphic look, layout, and colors. A
theme consists of one or more PHP files that define the HTML output of your site's pages, along
with one or more CSS files that define the layout, fonts, colors, and other styles.
Region, Block, Menu
Pages on your Drupal site are laid out in regions, which can include the header, footer, sidebars,
and main content section; your theme may define additional regions. Blocks are discrete chunks of
information that are displayed in the regions of your site's pages. Blocks can take the form
of menus, the output from modules (e.g., hot forum topics), or dynamic and static chunks of
information that you've created yourself (e.g., a list of upcoming events).
There are three standard menus in Drupal: Primary Links, Secondary Links, and NavigationPrimary Links, Secondary Links, and NavigationPrimary Links, Secondary Links, and NavigationPrimary Links, Secondary Links, and Navigation.
Primary and Secondary links are built by site administrators, and displayed automatically in the
page header of many themes (if not, you can enable their blocks to display them). Navigation is the

catch-all menu that contains your administration menus, as well as links supplied by modules on
your site. You can also create your own custom menus, and display them by enabling their blocks.
You can customize menus in several ways, such as reordering menu items by setting their “weight”
or simply dragging into place, renaming menu items, and changing the link title. You can move a
menu item into a different menu by editing the Parent property of the menu item.
You can also add custom menu items to a menu, from the Add menu item tab of the Menu
administration screen. To create a menu item, you will need to provide the path to the content,
explained above.
In all cases a menu item will only be shown to a visitor if they have the rights to view the page it
links to; e.g., the admin menu item is not shown to visitors who are not logged in.

1.41.41.41.4 Content TypesContent TypesContent TypesContent Types
A single web site could contain many types of content, such as informational pages, news items,
polls, blog posts, real estate listings, etc. In Drupal, each item of content is called anode, and each
node belongs to a single content type, which defines various default settings for nodes of that type,
such as whether the node is published automatically and whether comments are permitted. (Note
that in previous versions of Drupal, content types were known as node types.)
When you first install Drupal with the default installation profile, you will have two content
types defined: "Page" and "Story". When you enable other core and contributed modules (by
visiting Administer >> Site Building >> Modules), you will find that you have other content types
available; you can also create your own content types. Here is a list of the content types associated
with core Drupal modules
Blog EntryBlog EntryBlog EntryBlog Entry
A Blog (short for weblog) is an online journal or diary, and the core Blog module allows registered
users on your site to create their own blogs. Each entry in a user blog has content type Blog Entry.
Book PageBook PageBook PageBook Page
Book pages are designed to be part of a collaborative book, enabled by the core Book module. In
older versions of Drupal, only nodes of content type Book Page could be added to a book, but
now nodes of any content type can be part of a book.
CommentCommentCommentComment
Comments actually aren't nodes, so Comment is technically not a "content type". Enabling the
Comment module allows site visitors to add comments (typically short notes and replies to other
comments) to nodes on the site.
ForumForumForumForum
A Forum node defines a topic for a forum discussion; people can reply to the topic by using
comments. Forum nodes are organized into subject areas via Taxonomy (list of categories).

PagePagePagePage
The Page content type is enabled in Drupal in the default installation profile. Typically Pages are
used for static content that can (but are not required to) be linked into the main navigation bar.
PollPollPollPoll
A poll is where a multiple choice question is asked, and users can answer and see other people's
answers to questions.
StoryStoryStoryStory
The Story content type is enabled in Drupal in the default installation profile. Stories are generally
used for information whose relevance decreases as time passes (such as news items), so that newer
Stories will typically be placed higher on the page than older Stories.
Related link to the Drupal Content Construction Kit is as follows: http://drupal.org/project/cck
1.51.51.51.5 DrupalDrupalDrupalDrupal----viewing/editing a pageviewing/editing a pageviewing/editing a pageviewing/editing a page
In normal content or website design softwares like Frontpage, etc. there is a feature of looking at
the preview the changes performed on the content or to the layouts. In Drupal there is nothing as
such preview
Drupal just provides a unified interface.
Looking at the website, you are previewing it. To get the experience of a anonymous user, log
out and experience.
Drupal usually looks pretty much the same to all browsers as it does to editors, only with
different features and menu items available.
Authenticated users with appropriate permissions will see the 'edit' tabs above their pages.
That's often the only difference between editor and user experience.
1.61.61.61.6 Understanding Drupal pathsUnderstanding Drupal pathsUnderstanding Drupal pathsUnderstanding Drupal paths
In Drupal terms, a path is the unique, last part of the URL for a specific function or piece of
content. For instance, for a page whose full URL is http://somesite.com/?q=node/7, the path
is node/7. If site is using clean URLs(http://drupal.org/node/15365), the full URL in this example
would be http://somesite.com/node/7; the path would still be node/7. Because URL
aliases(http://drupal.org/handbook/modules/path) can completely replace what visitors see as the
URL, the paths discussed here (which are still how Drupal decides what content to show) are
sometimes called internal paths. Usually Clean URL’s and internal paths are very effective way to
create the Search Engine Friendly URL.
Drupal paths are important because many configuration screens in the Drupal admin area use
them. For instance, when you are adding a new item to a menu, you tell Drupal what page the
menu item should point to by entering the path to the page.Here are some examples of paths you
might find in a Drupal site

node/7
taxonomy/term/6
admin/content/comment
user/login
user/3
URL can have several forms
http://somesite.com/?q=[something] -- In this case, the [something] after ?q= is the path. For
example, if the URL is http://somesite.com/?q=node/7, the path is node/7.
http://somesite.com/[something] or http://somesite.com/[your Drupal subdirectory]/ [somet
hing] -- In this case, the [something] after the base path of your Drupal site is the path. For
example, your URL could be http://somesite.com/node/7 or http://somesite.com/mysubdir/
node/7; the path in either case is node/7.
How to find Drupal pathsHow to find Drupal pathsHow to find Drupal pathsHow to find Drupal paths
There are several ways to find the path to a particular page on your Drupal site. If you know how
to navigate to the page, you can go there and find the URL in your browser’s URL bar.
Roll mouse over a link to the page, and most browsers will show the URL in the status section
at the bottom of the browser window.
For Taxonomy term pages, find the URL in the Taxonomy administration page Administer >
Structure >Taxonomy. Each term should be a link to its taxonomy page. Roll Mouse over the
link or follow the link to find its URL.

In order to remove any confusion in user regards in terms of Drupal installation. This is important
to understand as it will help plan the installation of Drupal and remove any confusions, in terms of
users, as they may arise.
Different UsersDifferent UsersDifferent UsersDifferent Users
Computer User
The person installing Drupal must have access to the computer where the installation lives. The
individual installing Drupal on local system is Computer User. If you are installing Drupal at a
remote server such as a web hosting, then the computer user account could be called one of the
following
Web hosting account login
FTP login
Cpanel login
Secure shell (SSH) login

Who are the people who are associated with the computer user? In some cases, like for your own
computer or for some FTP logins, these "users" are individual people. In other cases, such as a web
hosting account login or Cpanel, one user (or "account") name/password is used to log in to control
the account and may be shared by several people.
Database User
Drupal installation requires a database to run. (MySQL and PostGreSQL are the best supported
database programs compatible with Drupal.) Databases typically have access control mechanisms
and require "users" with the right permissions to change the database (add/remove/edit data, create
tables, etc.). A Drupal installation needs to have full control over the database, so when you set up
a new Drupal site, you (or your web hosting company) create a database user with full privileges
and then give the user name and password to the Drupal installation so that Drupal will have full
control over the database. The database user information is stored in the the settings.php file,
which is either in sites/default or a different subdirectory of sites in your Drupal installation. Who
is the database user? The database "user" is not a person. It is an account created with the database
software in order to give Drupal control of the database.
User/1
"User/1", also known as the "maintenance" account or "super-user account" is the Drupal account
you are prompted to create immediately after you have successfully installed a new Drupal site.
This account is unique to your site (it doesn't have anything to do with Drupal.org or any other web
site). This account is different from all other users in a Drupal installation because it has no
permissions limitations ("permissions" were called "access control" in Drupal 5 and before).
"User/1", in Drupal 6 and before, is also the only account that can launch the update.php script that
you need to run after a software upgrade. Who is user/1? User/1 shouldn't be associated with an
individual person, but rather with the person or persons who have the responsibility for keeping
software up-to-date on your site.
It is a best practice to avoid creating site content with user/1. That is so because it is awkward when
responsibility for site maintenance done as User/1 needs to change to a new person if the original
User/1 wrote content that still needs to be associated with him/her. The content written by the
original author would have to then be assigned to a new user account. It's better to simply create
that second account immediately after installing the site.
User/2 and all others
User/2 and all other registered users on your Drupal site should each be associated with an
individual person. Registered users can be assigned to roles, which are given fine-grained
permissions to allow different users different access to administer the site and add content.
User management moduleUser management moduleUser management moduleUser management module User rights are managed using Administer->User management.
User management is broken down to 5 sections:
Access rules - Define different access rules for Drupal based site; allow/disallow users, emails
and IP addresses
Permissions – Define Modules availability for anonymous and/or authenticated users

Roles - Drupal comes with two default user roles - anonymous user and authenticated user; you
can add additional roles such as administrator, moderator, etc. as per the requirement of the
content and process workflows.
User settings - Configure the user registration settings, the emails notifying a user for new
registration, password recovery, etc
Users - shows a list of your current users; you can also add new users or block existing ones

1.91.91.91.9 Drupal SecurityDrupal SecurityDrupal SecurityDrupal Security
Drupal being an Open Source CMS, many people have this question, whether content, and site
itself are secure on Drupal. Answer to which is, world’s most secure websites like White House
switched to Drupal. Issues like Injection, Cross Site Scripting, Session Management, Cross Site
Request Forgeries, and others all of standard solutions in the Drupal API.
Professional security audits of Drupal sites have generally found that the vast majority of security
holes (90% or more) are present in the custom theme or modules written by that site's developers.
That code did not get the same public scrutiny that all code on drupal.org receives.
In addition, problems at the server level (such as using insecure protocols like FTP) are more
likely to be the means of a successful attack than vulnerability in Drupal - especially Drupal core.
1.101.101.101.10 Drupal versions and their numberingDrupal versions and their numberingDrupal versions and their numberingDrupal versions and their numbering
At any given time, there are two major release series of Drupal which are supported. Currently,
these are Drupal 5 and Drupal 6. Updated versions of each of these are issued on a regular basis.
For example, within the Drupal 6 series, several versions have been and will continue to be
released: 6.0, 6.1, 6.2, etc. These versions are sometimes collectively referred to as "6.x"; however,
they are not all equal. Version 7 will be released in January, 2011.
How to Know which version is running? Administer >> Reports >> Status report.... This will list your
version number if you have Drupal 6.0 or later. In Drupal 5.x and earlier, the path to go to is
Administer >> Logs >> Status report....
Failing that, look for a file called CHANGELOG.txt in the root of your Drupal directory and open
it up to find the version you are running.
If CHANGELOG.txt is missing, you can also check in system.module for a line at the top like:
define('VERSION', '5.5');
In deciding between Drupal 6 and Drupal 7, several factors should be taken into consideration.
Drupal 7 is newer, will be supported longer, and contains more features and enhancements than
Drupal 6; therefore, if all else is equal, use Drupal 7. However, the releases of contributed
modules, themes, translations, and installation profiles compatible with each major Drupal release
series sometimes lag behind Drupal itself, so if the functionality you need is not yet available for
Drupal 7, this may affect your decision.
Drupal 8 is currently in development and is not yet ready for production use. When version 8.0 is
released, Drupal 6 will no longer be supported or receive security updates, and you are strongly
advised to upgrade your Drupal 6 sites to Drupal 7 at that time.
New stable releases of Drupal core are scheduled to occur within particular release “windows“:
A bug fix release window is on the first Wednesday of each month.
A security release window is on the third Wednesday of each month.
A release window does not necessarily mean that a release will actually be made on that date, but it
exists so that site administrators can know in advance which days they should be on the look out
for one.

The version number indicates the version of Drupal core the contribution is compatible with,
whether it is a stable or development release, and what specific "patch level" of the code it
represents. These numbers have the form
CoreCompatibility-Major.PatchLevel[-Extra]
CoreCompatibilityCoreCompatibilityCoreCompatibilityCoreCompatibility is required, and will be something like "4.7.x", or "5.x", to indicate what
version of Drupal core this contribution is compatible with. Since the API for Drupal core
does not change across stable releases, a module that is compatible with Drupal core 4.7.1
would also work with 4.7.3. This is why the version strings for contributions contain the
character 'x' to show that they are compatible with any core release ("4.7.x") not just a specific
version of core ("4.7.1").
MajorMajorMajorMajor is the major revision number, which indicates what set of functionality a given release
has, if it is stable (bug-fixes only) or development (new features), and so on. The default branch
for a given release of core (for example, the "DRUPAL-4-7" branch) will be major version 1. By
convention, this major revision should always remain stable, and only security patches and bug
fixes should be added to it.
PatchLevelPatchLevelPatchLevelPatchLevel is for a specific release of a given major revision. The first release would be patch
level 0. As bugs are fixed, each new releases would have a higher patch level number. If the
patch level is the letter "x", it indicates a development snapshot.
[[[[----Extra]Extra]Extra]Extra] is optional, and is for specifying things like "-dev", to indicate a development snapshot
from the end of a CVS branch (as opposed to an official release from a CVS tag). These
snapshots, by their nature, include changing code. It is therefore hard to know exactly what
revisions of each file they contain, and this makes them more difficult to debug. Development
snapshots also use "x" for the patch level to further indicate the variable nature of the code they
contain.

1.121.121.121.12 Drupal InstallationDrupal InstallationDrupal InstallationDrupal Installation
Drupal provides an installation script that automatically populates database tables and configures
the correct settings in the settings.php file. This section covers preparing for installation, running
the installation script itself, and the steps that should be done after running the installation script
has completed. It also explains how to do a "multi site" installation, where a number of different
Drupal sites run off the same code base.

Before installing please go through the Drupal Terminology. Below are the best practices to be
followed before proceeding:
If you are going to invest the time to set up a CMS, then you should protect your investment by
following some simple best practices. The following list contains some quick pointers
Plan your site.Plan your site.Plan your site.Plan your site. DrupalDrupalDrupalDrupal provides a good toolset to help you build your site but you still need to
plan. Good wireframes and proper planning can avoid significant misunderstandings and
problems later.
Plan for the futuPlan for the futuPlan for the futuPlan for the futurererere. You should revisit and reevaluate your site each time there is a major
version release of Drupal. This does not mean you have to upgrade it, but you should evaluate
and plan for an upgrade approximately each 12-24 months.
Get involved in the communityGet involved in the communityGet involved in the communityGet involved in the community. This will help you follow development trends and, while
helping others, you may just come across a cool idea that solves your own problem.
Back up your siteBack up your siteBack up your siteBack up your site. Back up both the database and the files on the web server. Test your
backups! If you don't test them, you have no idea if you are doing it right.
Test your PHP snippetsTest your PHP snippetsTest your PHP snippetsTest your PHP snippets. Drupal gives you a great deal of power and flexibility when using PHP
code in blocks. Unfortunately, a stray character or a missing semi-colon breaks PHP. Drupal
then attempts to evaluate this broken code on any requested page, the PHP interpreter chokes
on it and therefore your whole site is broken. Fortunately, there is a very simple and easy
solution. Instead of writing and testing your code inside the administer > blocks page, go to
create content and create a new story or page node. Use PHP input format, write the code, and
the Preview to debug your code. When you are satisfied that your code is working, copy and
paste the code into the block.
System requirementsSystem requirementsSystem requirementsSystem requirements
A minimum base installation requires at least 3MB of disk space but you should assume that your
actual disk space will be somewhat higher. For example, if you install many contributed modules
and contributed themes, the actual disk space for your installation could easily be 40 MB or more
(exclusive of database content, media, backups and other files). Extra space for webserver, PHP
and database will be required, this will be evident at the time of installation of a particular
component.

Drupal has been deployed successfully on both Apache and IIS.
ApacheApacheApacheApache (Recommended)(Recommended)(Recommended)(Recommended)
Drupal will work on Apache 1.3 or Apache 2.x hosted on UNIX/Linux, OS X, or Windows.
The majority of Drupal development and deployment is done on Apache, so there is more
community experience and testing performed on Apache than on other web servers.
You can use the Apache 'mod_rewrite' extension to allow for clean URLs.

Microsoft IISMicrosoft IISMicrosoft IISMicrosoft IIS
Drupal core will work using IIS 5, IIS 6, or IIS 7 if PHP is configured correctly.
To achieve clean URLs you may need to use a third party product. For IIS7 you can use the
Microsoft URL Rewrite Module or a third party solution.
When using Drupal on IIS 7 with fastcgi you must install Hotfix kb954946, or wait until the hotfix
appears in a package update (recommended). KB954946 was included in Windows 2008 Server
SP2
Drupal is being developed to be web server independent, but we have limited or no reports of
successful use on web servers not listed here.
The total file size of your Drupal installation will depend on what you add to your site, but
Drupal core files alone will take up approximately 2 to 3 MB uncompressed. The exact size
depends on the version of Drupal you have installed.

NOTE:NOTE:NOTE:NOTE: Drupal makes use of some features not available on some inexpensive hosting plans so
please check that your host allows database accounts with the following rights
SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER.
These rights are sufficient to run Drupal core 6.x and later versions.
Some contributed modules, and also Drupal core 5.x (but not Drupal core 6.x), additionally

PHP
RecoRecoRecoRecommendedmmendedmmendedmmended: PHP 5.2 for Drupal 5 and 6, PHP 5.3 for Drupal 7
RequiredRequiredRequiredRequired: PHP version 4.4.0 or higher for Drupal 5 and Drupal 6, PHP 5.2.5 or higher for
Drupal 7
PHP 5.3 is not yet supported by Drupal 5.x, but is supported by Drupal 6.14 core and higher
(see the release notes for 6.14) and also by Drupal 7.x. Note that some contributed modules
may not be compatible with PHP 5.3, and that some PHP 5.3 configurations still show
warnings with Drupal 6.14.
PHP 5.2.5 or higher is a requirement for Drupal 7. (Distributions of PHP 5.2.4 that include
backported security patches, such as the version included in Ubuntu Hardy, should also work
with Drupal 7.)
PHP memory requirements can vary significantly depending on the modules in use on your
site. Drupal 6 core requires PHP's memory_limit to be at least 16MB, and Drupal 7 core
requires 32MB. Warning messages will be shown if the PHP configuration does not meet
these requirements. However, while these values may be sufficient for a default Drupal
installation, a production site with a number of commonly used modules enabled (CCK, Views
etc.) could require 64 MB or more. Some installations may require much more, especially with
media-rich implementations. If you are using a hosting service it is important to verify that your
host can provide sufficient memory for the set of modules you are deploying or may deploy in
the future.
The PHP extension for connecting to your chosen database must be installed and enabled.
Drupal's currently supported database connectors are: mysql (the original MySQL
extension), mysqli (an improved connector for newer MySQL installations), and pgsql (for
PostgreSQL). Drupal 6.x does not provide the option to select the mysql connector if mysqli is
enabled in your PHP configuration.
PHP XML extension required for blogging API, drupal. This extension is enabled by default in
a standard PHP installation; the Windows version of PHP has built-in support for this
extension. Enabling the XML extension also enables PHP DOM. DOM is now a systems
requirement.
An image library for PHP such as the GD library is needed for image manipulation (resizing
user pictures, image and image cache modules). GD is included with PHP 4.3 and higher and
usually enabled by default. ImageMagick is also supported for basic image manipulations in
Drupal core but there is much less support from contributed modules.

If you have administrator rights, and GD is not already available (look in phpinfo) it can usually
be installed by going:
sudo apt-get install php5-gd
or on Redhat/Centos:
sudo yum install php-gd
PHP needs the following configuration directives for Drupal to work (only directives that differ
from the default php.ini-dist / php.ini-recommended):
register_globals: off; this is the default value, but some hosts have it enabled
error_reporting set to E_ALL & ~E_NOTICE. In Drupal 7 it will be E_ALL.
safe_mode: off. Safe mode may interfere with file and image uploads.
Php Data Objects (PDO) must be activated for Drupal 7 to install and run correctly. Look
in your php.ini. Uncomment (remove the leading semicolon) at line
extension=php_pdo.dll, extension=php_pdo_mysql.dll. If these lines are not there, add
them.
It is also recommended to have setting: session.cache_limiter: nocache
Some of these settings are contained in the default .htaccess file that installs with Drupal, no
need to set them explicitly. Note, however, that setting PHP configuration options from
.htaccess only works under the following conditions:
With Apache (or a compatible web server)
If the .htaccess file is actually read, i.e. AllowOverride is not None
If PHP is installed as an Apache module
Drupal 7 may require the time parameter to be at least 30 seconds.
In some shared hosting environments, access to these settings is restricted. If you cannot
make these changes yourself, please ask your hosting provider to adjust them for you.
If using xdebug, ensure that the xdebug.show_exception_trace value is set to 0, or this
could cause Drupal's installer to crash.

Before you start, check that the software versions on your server meet the system requirements.
Download and extract files
To download Drupal and copy it to your webserver:To download Drupal and copy it to your webserver:To download Drupal and copy it to your webserver:To download Drupal and copy it to your webserver:
Using your web browser, navigate to http://drupal.org/project/drupal.
Click the "download" link beside the version of Drupal you want to download. This will save the
file to your computer. The file is a compressed archive which contains many files and folders.
Make note of the name of the file and where it is downloaded to on your computer.
Log in to your hosted account’s control panel (your hosting company will have provided this
address to you).
Create a target directory where your site will be hosted.
Upload the Drupal files:
Navigate to your HTML directory
Assuming that your ISP will allow you to upload an archive file and uncompress that file, the
process of uncompressing the file will generally create a new directory which contains all of the
files and folders in the archive. After it has been unarchived, you can rename this folder (eg.
"drupal7" or "gallery_blog").
Please note: Attempting to upload the contents of the archive one by one is best avoided as the
arrangement of these files must be maintained if Drupal is to function properly.
Be sure to consider how you will organize your folders if you are hosting multiple sites. You
will want to create the folder for your new Drupal 7 site at the same level as other sites.
Upload your compressed .tar.gz or .zip file
Uncompress or Unarchive the file on the server. (This process will vary from one ISP to
another.)
NoteNoteNoteNote: - Avoid attempting to reconstruct this set of files or changing the location of specific files will
likely break your new site.
NoteNoteNoteNote: - As an alternative, to extract the files locally (on your computer) you can generally double
click on the file. If your computer does not already know how to open this file, you may need to
locate a tool to extract compressed files—you can do an Internet search using the name of your
Operating System (eg. Mac OSX, Ubuntu, Red Hat, or Windows) and ‘extract tar.gz’.
Rename the folder which contains the uncompressed files. Locate the file and extract its
contents. The result should be a new directory which has the same name as the archive file that
you downloaded.

Set up a Domain and point it to the directory containing Drupal's files
To set up and configure a domain name which points to this new directory, you will need to refer
to your Internet Service Provider (ISP). This process can be accomplished in a variety of ways and
the process is specific to the tools provided by your ISP. In general you want to:
Register a Domain Name eg. http://somesite.com.
Configure your hosting account to use this domain name.
Point the domain name to your new folder/directory, which contains the uncompressed Drupal
files
NoteNoteNoteNote: These steps can take some time. Many ISPs provide an ‘Add Domain’ function which
allows you to simply specify the domain name to be used and the directory which it points to. It
can take minutes or hours for this setup to go into effect.
If you are registering a sub-domain, the portion of the name which is before the domain name,
perhaps in place of the ‘www’ (eg. http://myown.somesite.com), these tend to process almost
immediately, but again it depends on your ISP.
Create the configuration file and grant permissions
In order to set up new site
Modify the settings.php file via your browser.
By default at the time of un-archiving these files, only default.settings.php file exists with
permissions of Read Only.
Copy the file, rename it to settings.php
Temporarily change the permissions so that the server can Read and Write to this file when a
user makes changes via a web browser.
Move up one level to the /sites directory and change the permission on the /default directory
(folder), as this is the place where files created or uploaded via the web interface will be stored.
Copy the file default.settings.php and rename it to settings.php
Use ISP’s file manager to navigate to the /sites/default directory
Select the default.settings.php file (usually done by checking a box next to the file)
Copy the file, naming the new copy ‘settings.php’
Change the permissions of the settings.php file.
ISP’s file manager select the file ‘settings.php’ and click on permissions.
Add the permissions for the file to be written by the web server (i.e. web users). If system is
asking you to use a numeric value to CHMOD the file you will want to use 666, this will set the
file to be written by anyone.
Save changes.

The installation script should change the permissions of the ‘settings.php’ file back to read-
only. At the end of initial configuration of site. It is recommended to change the permissions of
settings.php to Read Only.
Change the permissions of the /default directory.
ISP’s file manager select the /default folder and click on permissions.
Add the permissions for the folder to be written by the web server (i.e web users).
Save change.
Create the Drupal database
Create a new, empty database for Drupal to use.
Add a user who has full access to this newly created database.
Methodology to create the DB will likely depend on ISP.
Most common tool used to administer databases is "phpMyAdmin". It is possible that you will have
privileges to create new databases using this tool. However, it is more likely that your ISP provides
access to phpMyAdmin so that you can work with content in your database. When you create a
new site, the related database must be created using the ISP’s control panel.
Option 1: Create a new DataOption 1: Create a new DataOption 1: Create a new DataOption 1: Create a new Database using your ISP’s Control Panelbase using your ISP’s Control Panelbase using your ISP’s Control Panelbase using your ISP’s Control Panel
For this option to run successfully, ISP will provide a database section in account’s control panel.
Here you will be able to create the database, adding a username and password to access the
database. The approach and steps here will vary depending on ISP, in general please specify:
Database Name (nick name of site)
username and
password
Combination of username, password and DB Name will be used by the website and also for the
website and DB administration.
Please note: In case databases are hosted on a separate server than the webserver. In this case,
please specify the alias or IP of the server where the DB is hosted. This information can be
obtained by DBA.
Option 2: Create a new Database using phpMyAdminOption 2: Create a new Database using phpMyAdminOption 2: Create a new Database using phpMyAdminOption 2: Create a new Database using phpMyAdmin

Download and extract files
Download Drupal from http://drupal.org/project/drupal and extract the download file to a folder
on your hard drive. (Replace the 'xx' in drupal-x.x.tar.gz with the actual version you've
downloaded.)
wget http://drupal.org/files/projects/drupal-x.x.tar.gz
tar -zxvf drupal-x.x.tar.gz
Move the files to a directory within your web server's document root or your public HTML
directory using the following command, substituting drupal-x.x with the actual version number.
mv drupal-x.x /var/www/
You can install and use Drupal in other languages by downloading translations from
http://drupal.org/project/translations. Extract the files into the Drupal directory (e.g.
/var/www/drupal-x.x)
Create the configuration file and grant permissions
In the sites/default directory, copy the default.settings.php file and rename the copied file to
settings.php.

cp sites/default/default.settings.php sites/default/settings.php
Give the web server write privileges (666 or u=rw,g=rw,o=rw) to the configuration file.
chmod a+w sites/default/settings.php
Give the web server write privileges to the sites/default directory.
chmod a+w sites/default
Create the Drupal database
To complete the installation, you must create an empty database and a user with full access the
newly created database for Drupal to use. You can do this by command line, or through
phpMyAdmin or another database client.
mysqladmin -u username -p create databasename
Where 'username' is a MySQL user which has the CREATE and GRANT privileges. MySQL will
prompt for the 'username' database password. Next you must set the access database rights. Log in
to MySQL:
mysql -u username -p
At the MySQL prompt, enter:
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE
EMPORARY TABLES, LOCK TABLES
ON databasename.*

'localhost' is the server name used to access MySQL
'password' is the password required for that username
If successful, MySQL will reply with “Query OK, 0 rows affected”.
Run the installation script
You are now ready to run the installation script. Point your browser to the base URL of your
website (e.g. http://www.somesite.com, http://www.somesite.com/drupal or http://localhost/drupal).
The installation wizard will guide you through several screens to set up the database, add the first
user account, and provide basic website settings. Follow the wizard to finalize the installation as
explained in previous section.
Installing the profile
Start by downloading the installation and profile and unpacking it.
Copy the entire directory that you just unpacked into the profiles directory of your core
installation. For example, if you have core installed at /home/www/htdocs and you downloaded

and unpacked an installation profile called "fooprofile", copy the entire "fooprofile" directory
into /home/www/htdocs/profiles/fooprofile.
Read the documentation on the installation pack you downloaded. This can either be found on
the profile's project page or in the README.TXT that came with the download. It should
contain installation instructions such as listing the required extra modules and/or themes that
you will have to download.
Download these modules and themes and put them in the right directory. This is
usually sites/all/modules and sites/all/themes.
Go to your site's install.php and select which installation profile to install.

Setup cron jobSetup cron jobSetup cron jobSetup cron job to perform following
Search module's indexing of your website's content
Aggregator module's retrieval of feeds
Ping module's notification of other sites of updates
System module's routine maintenance tasks, archiving logs, all depend a properly
configured cron job.
Cron is a program that executes commands at specified intervals. These commands are called
"cron jobs." Cron is available on Unix, Linux and Mac servers. Windows servers use a Scheduled
Task to execute commands.
Frequency of the cron jobs will depend on the usage of the site, on a normal site it can be once a
day where as for the more active sites it will be more often, this required to be scheduled properly
in order to ensure smooth running of the website.
The cron command
In the following example, the crontab command shown below will activate the cron tasks
automatically on the hour:
0 * * * * wget -O - -q -t 1 http://www.somesite.com/cron.php
In the above sample, the 0 * * * * represents when the task should happen. The first figure
represents minutes – in this case, on the "zero" minute, or top of the hour. (If the number were,
say, 10, then the action would take place at 10 minutes past the hour.) The other figures represent,
respectively, hour, day, month and day of the week. A * is a wildcard, meaning "every time." It is
recommended to go through Man pages of the OS the cron job is being created. The rest of the
line basically tells the server to "ping" the url http://www.somesite.com/cron.php.
NOTENOTENOTENOTE: The -O is "dash capital letter O", not "dash zero". Yes, the capital O is important.
Lowercase o won't work
Here is a diagram of the general crontab syntax, for illustration:
# +---------------- minute (0 - 59)
# | +------------- hour (0 - 23)
# | | +---------- day of month (1 - 31)
# | | | +------- month (1 - 12)
# | | | | +---- day of week (0 - 7) (Sunday=0 or 7)
# | | | | |
* * * * * command to be executed
Thus, the cron command example above means "ping http://www.somesite.com/cron.php at the
zero minute on every hour of every day of every month of every day of the week."

Drupal and Cron jobs
Every Drupal install requires regular actions to handle maintenance tasks such as cleaning up log
files and checking for updates. Cron.php is the file that Drupal uses to run the maintenance
process.
For instance, if your site were www.somesite.com, loading the URL
http://www.somesite.com/cron.php in your browser would run the maintenance. This page is
automatically set up when you install Drupal. Simply loading the URL will run the maintenance.
Nothing more is required.
How to set up a cron job
Cron jobs are scheduled by editing the crontab. A crontab is an OS text file that contains the
commands to be run with a frequency, as explained above. This file can be created and edited
either through the command line interface, or, if you manage your website through a web-based
control panel such as cpanel or Plesk, you will use the web interface.
In order to schedule your cron job in Plesk for Linux, go to Settings > Scheduled Tasks in the
General Group. Select the system user account on whose behalf the task will be executed. Click
"Schedule New Task". Specify when to run your command. You can schedule the time using the
UNIX crontab entry form.
Otherwise, check with your hosting company for detailed instructions if you are using a web-based
control panel.
To edit a crontab through the command line, type:
crontab -e
Add ONE of the following lines:
45 * * * * /usr/bin/lynx -source http://www.somesite.com/cron.php
45 * * * * /usr/bin/wget -O - -q -t 1 http://www.somesite.com/cron.php
45 * * * * curl --silent --compressed http://www.somesite.com/cron.php
This would have a lynx, wget, or curl visit your cron page 45 minutes after every hour.
Three options are provided in case either wget, lynx or curl are not installed on the server.
There are many ways to configure a cron job. If you have full access to crontab features, you
should be able to simply paste in one of the above example commands – be sure to replace
"somesite.com" with your own web domain.
If you're on shared hosting, you should be able to find cron job configuration somewhere in your
hosting control panel. Some hosts even have cron "wizards" that walk you through the cron
configuration, making it much easier if cron is new to you.
On a Windows system you can accomplish the same thing with scheduled tasks to launch Internet
Explorer pointed to the URL.
Security notes
It is possible to run cron.php directly via scripts/drupal.sh with Drupal 6. Drupal.sh allows a
Drupal page to be executed from a shell script. To do so, add the following cron job to run as the

Apache user
/full/path/to/drupal.sh --root /full/path/to/site/root/ http://default/cron.php
Note that http://default/cron.php is NOT shown as an example, it should be used as is, without
changes.
Taking this approach allows cron.php to be blocked to prevent remote access.
To block remote access to cron.php, in the server's .htaccess file or vhost configuration file add this
section
<Files "cron.php">
Order Deny,Allow
Deny from all
Allow from localhost
Allow from 127.0.0.1
Allow from xx.xx.xx.xx <-- your IP address
</Files>
If you take this approach and use drupal.sh to call cron.php, it is probably best not to use the root
user to run the cron job. A non-privileged user account, or the Apache account user, for example
http-service or www-data, is a better choice. To do so, call crontab -e when logged in as a non-
privileged user, or for the Apache account on a Debian server, for example, you can add a user
parameter
sudo crontab -e -u www-data
The downside to this method is that any URLs generated by cron jobs using this method will not
be properly formed, starting with "http://default/".
Cron Jobs with Multiple sites
If you run many sites, you can use this tip to make managing your cron jobs easier. To minimize
the clutter, create a /etc/cron.5min directory and have crontab read this directory every five
minutes.
*/5 * * * * root run-parts /etc/cron.5min
Then place multiple individual files into the /etc/cron.5min directory, one for each site. The files
can be named "site1", "site2", etc. -- note that run-parts may fail to detect files which contain a dot (.)
in their name. To make sure that all of your files are visible to cron, type this at a shell prompt
$ sudo run-parts --test /etc/cron.5min
and make sure that all of your files are listed.
Each of the files in /etc/cron.5min should contain one line:
/usr/bin/lynx -source http://(full site URL)/cron.php > /dev/null 2>&1
or, alternatively, one of the curl or wget commands specified above.
If this doesn't work, try putting another line at the start of each file

#!/bin/sh
and make sure that the files are executable by doing
$ sudo chmod u+x /etc/cron.5min/*
Setup to get the Clean URL’sSetup to get the Clean URL’sSetup to get the Clean URL’sSetup to get the Clean URL’s – by default the URL’s of the dynamic pages or static pages will be
something like “ http://www.somesite.com/?q=node/100” this is not a search engine or user
friendly URL. Search engines will not index such kind of pages. To Setup the clean URL, for
the most common server setup, which is an Apache web server running on some flavor of
Unix/Linux, with the mod_rewrite Apache module configured and mod_rewrite enabled in
httpd.conf configuration file. If this is a shared server then there might not be a permission to
modify the httpd.conf file, in which case this has to be programmatically handled.
Enabling Clean URL in Drupal
Clean URLs configuration page (Administer > Configuration > Search and metadata), show the
results, and allow you to save configuration.
You can enable or disable it at a later time by following these steps
Navigate to the Clean URLs configuration page (Administer > Configuration > Search and
metadata)
Wait for the automated Clean URLs test to run.
Check or uncheck the Enable clean URLs checkbox
Click "Save configuration"
Even if Clean URLs are successfully enabled at install-time, if you have a dedicated server you may
still want to follow the steps (below) to enable the more efficient httpd.conf rewrite method for
clean URLs. If you choose to do that, you might want to turn off Clean URLs while you are
working on the server.
Clean URL on dedicated Server using httpd.conf
Enable mod_rewrite for Apache. You can talk to your web host or consult the Apache
documentation for mod_rewrite to get more information on how to do this. At a minimum,
this will involve making sure that mod_rewrite is enabled for your installation of Apache.
To test if mod_rewrite is available in Apache2, you can type the following at a command
prompt, to list all installed Apache modules apache2ctl -M
On some systems this command may be apachectl -M
In the output, check to see if the rewrite_module is included in the list of modules.
If the rewrite module is not in the list, it will have to be either compiled-in or made available as
a loadable module. Generally speaking, you can tell Apache to load the module by including
LoadModule rewrite_module modules/mod_rewrite.so

AddModule mod_rewrite.c in your Apache configuration file. Be sure to uncomment
AddModule mod_rewrite.c, if it is in your configuration file but has been commented out. The
following may work to enable the module without editing any files
a2enmod rewrite
NoteNoteNoteNote that these approaches may not work for all combinations of operating system and Apache
server -- consult the Apache documentation that came with your Apache software for the correct
syntax.
Remember to restart Apache for the new configuration to take effect.
The next step is to locate the appropriate Apache configuration file for your site. Depending on
your server configuration, the appropriate Apache configuration file could be httpd.conf, a virtual-
host-specific file (vhost.conf), a specific site file (e.g. "default"), or apache2.conf. They are usually
located in /etc/httpd/conf, /etc/apache2, or a sub-directory; if not, try the command:
find /etc -name httpd*
to find the file if it is located elsewhere in your file system.
If you do not have write permissions to these files, and Clean URLs are not working out-of-the-box
for you, you may have to ask your systems administrator or hosting provider for help. You may still
be able to readthese configuration files to troubleshoot a little however.
The next step is to copy or include the Drupal-specific settings directly into your configuration file.
There are instructions here for how to include the Drupal directives in your configuration file.
Consult the .htaccess file in Drupal page for examples of rules, such as the following
<Directory /var/www/somesite.com>
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
</Directory>
Make sure that you are looking at the .htaccess file for your major version of Drupal (i.e., 7.x, 6.x,
5.x).
NoteNoteNoteNote: If you do not want to put the rewrite rules in your Apache configuration file, you can still
simply use the Drupal .htaccess file (as you would if you were on shared hosting). You will need to
have the Allow Override directive set in your Apache configuration file (this will allow local
.htaccess overrides on your site)
AllowOverride All
AccessFileName .htaccess
Read Behind the scenes with Apache's .htaccess for a thorough review of .htaccess. You may also
find it helpful to view samples of Apache 2 AllowOverride directives.

Server configuration for Clean URLs on a shared server, with .htaccess
The standard Drupal installation contains a sample .htaccess file which should be sufficient to get
Clean URLs running. Do not miss to copy this file, as it will be hidden in the normal view because
this file is having dot in front of the file name (use ls-alrtg to get the listing). Before enabling Clean
URLs, make sure installed location contains this file.
Still if the Clean URL’s don’t work, contact the hosting provider.
Make sure that .htaccess file usage
Specify explicitly in Apache configuration to use .htaccess file. This is off by default, though most
hosts will have turned it on. To specify this use AllowOverride All directive .htaccess start working.
To check .htaccess read, temporarily add some garbage string to the file. Site will immediately start
returning a "500 Server Error" when you load a page from that directory due to this wrong
configuration. (Remove the garbage string immediately after this litmus test.)
If you do this, and your site does not break - then .htaccess is being ignored and you will not be
able to use clean URLs until you get support from your hosts, or enable it in httpd.conf as
described above. Some hosts allow you to enable this option through their site management
control panel, so look there first.
RewriteBase setting
The main configuration option which may need to be changed for your site is the RewriteBase.
This can be specified in the Drupal .htaccess file or in the httpd.conf file, depending on where you
are putting the Drupal rewrite directives. By default, the RewriteBase setting is commented out of
the Drupal .htaccess file, and that works well for many configurations.
If you are having trouble getting Clean URLs to work, you may need to change this setting. For
example, if your Apache DocumentRoot is /var/www/ (i.e., /var/www/index.html is what is
displayed when you point your browser at http://www.somesite.com/) and your Drupal installation
is installed in the subdirectory /var/www/mysite/, then the RewriteBase could be set to
RewriteBase /mysite
In some configurations, setting
RewriteBase / will allow clean URLs to work.
$base_url
You may need to manually set the $base_url variable in the settings.php file if not already set. It's
currently known that servers running FastCGI can run into problems if the base_url variable is left
commented out.
Multi-site
RewriteBase works when your Drupal installation serves only one site, or when all the sites it serves
are in the same subdirectory of their domains. For example,
RewriteBase /
will work for the following sites

http://www.somesite.com/
http://www.somesite2.com/
http://www.somesite3.com/
RewriteBase /mysite
will work for the following sites:
http://www.somesite.com/mysite
http://www.somesite2.com/mysite
http://www.somesite3.com/mysite
However, if your sites are in different subdirectories, RewriteBase will not work. You will need to
create a special rule for each subdirectory. For example, your Drupal installation may serve the
following sites
http://www.somesite.com/
http://www.somesite.com/mysite
In order to enable clean URLs for both sites, you will need to add
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^/mysite/(.*)$
RewriteRule ^(.*)$ /mysite/index.php?q=$1 [L,QSA] before the existing rewrite rules.
Location of index.php
For some server configurations, another change to the Drupal .htaccess file may be necessary. Find
a line that looks like this, near the end of your Drupal .htaccess file:
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
You may need to replace index.php with the URL path to your Drupal installation's index.php file.
For instance, if your site's home page URL is http://somesite.com/subdir/, you might need to
use /subdir/index.php instead of index.php. If your site's home page URL is http://somesite.com/,
you might need to use /index.php instead of index.php. This is necessary on some, but not all
server configurations.
Files Directory
In most cases, Drupal would create the files directory for you. If Drupal can't create the directory,
follow the instructions below.
After installing Drupal, you will need to ensure the directory files can be accessed by your Web
server. If it does not have the correct permissions you may get an error message stating that
"sites/default/files does not exist ..."
Here’s how
In the folder sites/default create a new directory called files.
Grant read, write and execute permissions on the new directory to the Web server.
Most FTP programs will allow you to create the new directory and set its permissions.

Once you've completed these steps confirm the appropriate permissions have been assigned by
navigating to Administer -> Reports -> Status report.
Scroll to the section "File system" and confirm your settings are now correct.
Check Apache-based Web Servers Settings
If the directory files is not "owned" by the Web server there are two ways to proceed. These
instructions assume you have shell access to the Web server. If you do not have shell access, please
contact your hosting provider for additional support.
Ideally you will be able to change the "owner" of the directory files to match the name of the Web
server. On a Unix or Linux-based server you may verify "who" the Web server is running as by
issuing the following commands:
$ ps aux |grep apache # for Apache 2.x
$ ps aux |grep httpd # for Apache 1.x
Depending on your Web server one of these commands will return a series of lines like this:
www-data 13612 0.1 0.9 50640 20340 ? S 12:29 0:08 /usr/sbin/apache2 -k start
The first column in the returned text is the "user" that your Web server is operating as. In this case
the user is www-data. To make your files directory writeable by the Web server you need to
reassign its ownership using the following command:
$ chown -R www-data sites/default/files
$ chmod -R 0700 sites/default/files
If you do not have sufficient permissions on your server to change the ownership of the folder, the
next best option is to provide group-write access to the folder with the following command:
$ chmod -R 0770 sites/default/files
You should also be able to adjust the directory's permissions using an FTP program as outlined
above.
Once you've completed these steps confirm the appropriate permissions have been assigned by
navigating to Administer -> Reports -> Status report. Scroll to the section "File system" and confirm
your settings are now correct.

Running more than one Drupal site, you can simplify management and upgrading of your sites by
using the multi-site feature. Multi-site allows you to share a single Drupal installation (including
core code, contributed modules, and themes) among several sites.
This is particularly useful for managing the code since each upgrade only needs to be done once.
Each site will have its own database and its own configuration settings, so each site will have its own
content, settings, enabled modules, and enabled theme. However, the sites are sharing a code base
and web document root, so there may be security concerns.

How to do it?
To create a new site using a shared Drupal code base you must complete the following steps:
Create a new database for the site.
Create a new subdirectory of the 'sites' directory with the name of new site, this explained
below.
Copy the file sites/default/default.settings.php into the subdirectory created in the previous step.
Rename the new file to settings.php.
Adjust the permissions of the new site directory, and grant write permissions on the
configuration file as explained above.
Make symbolic links if you are using a subdirectory such as somesite.com/subdir and not a
subdomain such as subd.somesite.com, this is explained below.
In a Web browser, navigate to the URL of the new site and continue with the standard Drupal
installation procedure.
It may also be necessary to modify your Web server's configuration file, httpd.conf so that Drupal
will override Apache's settings. This is true for all installations of Drupal and is not specific to the
multi-site install.
Process details for Domains, URLs, and sites subdirectory name
The new subdirectory of the sites directory has a name that is constructed from the site's URL. For
example, the configuration for www.somesite.com would be in sites/somesite.com/settings.php.
Do not include 'www' as part of the directory name.
Drupal will use the same sites/somesite.com directory for any subdomain of somesite.com,
including www, unless there is an alternative, matching subdomain sites subdirectory. For instance,
URL http://sub.somesite.com would be served from sites/sub.somesite.com, if it exists.
For a subdirectory URL, such as http://somesite.com/subdir, name the sites subdirectory as
follows: sites/somesite.com.subdir -- explained below on how to get subdirectory multi-site
working.
If installing on a non-standard port, the port number is treated as the first part of the subdomain.
For example, http://www.somesite.com:8080 could be loaded from sites/8080.somesite.com. If
that directory doesn't exist, Drupal would then look for sites/somesite.com, just like a real
subdomain.
Site-specific modules and themes
Each site configuration can have its own site-specific modules and themes in addition to those
installed in the standard 'modules' and 'themes' directories. To use site-specific modules or themes,
simply create a 'modules' or 'themes' directory within the site configuration directory. For example,
if sub.somesite.com has a custom theme and a custom module that should not be accessible to
other sites, the setup would look like this
sites/sub.somesite.com/settings.php
sites/sub.somesite.com/themes/custom_theme

sites/sub.somesite.com/modules/custom_module
Document root
One area of frequent confusion is that in a Drupal multisite installation the webserver document
root is the same for all sites. For example with the following three sites: somesite.com,
sub.somesite.com and somesite.com/site3 there will be a single Drupal directory and all sites will
be calling the same index.php file.
Some webhosts automatically create a new directory (i.e. somesite.com) when creating a new
domain or subdomain. In this case it is necessary to make it into a symbolic link to the main
Drupal directory, or better yet when creating the domain or subdomain, set it to use the same
document root as the site where you have Drupal installed.
Subdirectory multi-site
If you are attempting to get Drupal multi-site working using subdirectory URLs rather than
subdomain or different domain URLs, you may encounter problems. You'll start out by making a
directory such as sites/somesite.com.subdir, and putting a settings.php file there. If this works for
you, great! But it probably will not, until you make a symbolic link that tells your web server that
the document root for http://somesite.com/subdir is the same as the document root
for http://somesite.com. To do this, go to the somesite.com document root and type:
ln -s . subdir
(substituting the actual name of the subdirectory you want to make work).
If your codebase itself is in a subdirectory, then link your new site to the directory:
ln -s drupaldir subdir
This symbolic link is enough to resolve issues with subdirectory multi-site installations on at least
some web hosts. But if you still encounter problems, such as issues getting clean URLs to work
(especially if you had to edit the .htaccess file to get clean URLs working on the main
somesite.com domain site).
Note that these problems do not usually occur for multi-site installations using a subdomain, so
you might want to try that if you cannot get subdirectory multi-site to work. (However, subdomains
are not good for search engine rankings!)
Localhost alias for local workstation
On many systems it is possible to create entries in a "hosts" file to create aliases for the localhost
name for a local workstation. By creating aliases for localhost it is possible to create names such as
localdev1.somesite.com and localdev2.somesite.com, both for the local computer.
If on the other hand you use subdirectories in your local web root, create a symbolic link like this:
ln -s drupaldir subdir
and name your site folder localhost.subdir.

Domain name changes
Once a site is in production in a particular subdirectory under the sites directory, the subdirectory
should not be renamed, even if the Web site URL changes. This is because several database tables
(for example: system and files) include references to "sites/www.mydomain.com." Instead of
renaming the sites directory, you can create a symlink to the new URL from the old one. Navigate
to the sites directory and then use the following command:
$ ln -s /path/to/drupal/sites/old.domainname.com new.domainname.com
Security Concerns
You might want to reconsider using Drupal's multi-site configuration, in situations where the
administrators for all of the sites being run from the same code base are not either the same
person or a small group with a high level of mutual trust. The reason is that anyone with full
administrative privileges on a Drupal site can execute arbitrary PHP code on that site through
various means (even without FTP access to the site), and that arbitrary PHP code could be used
from one site to affect another site, if the two sites are in the same HTTP document root and
sharing the same Drupal code.
Multi-site with single codebase, different content database, shared user database, shared sign-on
Make a copy of /sites/default to /sites/site1 and another to /sites/site2. You may add modules
and themes directories in these new directories in the usual way for site-specific configurations.
A files directory should be there already, if it is not there then create that. Rename
/sites/site1/default.settings.php to settings.php and /sites/site2/default.settings.php to
settings.php (directories should have read write permissions).
Add these lines to your hosts files:
site1
site2
Create three empty MySQL databases:
drupal_site1
drupal_site2
drupal_shared_tables
Go to http://site1 and run through the install process in the normal way, using the database
name 'drupal_site1'.
In MySQL (please download the MYSQL web client) Administrator create a new back-up
project of the 'drupal_site1' database containing _only_ the tables to share, save it and run it.
Save .sql file on the hard disk.
Check Drupal tables for sharing users are as follows
authmap
profile_fields
profile_values
rolesessions
users

The absolute basic essential tables (if you don't want to share any data except for the users and
sessions, no profile data, roles, etc.) are
sessions
users
To Open ID authentication enabled also need to share the openid_associations table.
(This is not a definitive list. But other features like taxonomy, etc. can be shared. Each site has
its own permissions matrix - but share one across all sites.)
Edit the .sql script created and update the database name within to 'drupal_shared_tables'.
Using the Restore interface, run the .sql script. Now have a database called
'drupal_shared_tables' containing only the list of tables above.
Go to http://site2 and run through the install process in the normal way, using the database
name 'drupal_site2'.
Go back to original 'drupal_site1' database and drop the same list of tables from the schema.
Perform same for the 'drupal_site2' database.
Databases are ready now.
Browse to your Drupal application and edit /sites/site1/settings.php. Change these lines:
<?php
$db_url = 'mysqli://user:password@localhost/drupal_site1';
$db_prefix = '';
?>
To:
<?php
$db_url = 'mysqli://user:password@localhost/drupal_site1';
$db_prefix = array(
'default' => '',
'authmap' => 'drupal_shared_tables.',
'profile_fields' => 'drupal_shared_tables.',
'profile_values' => 'drupal_shared_tables.',
'role' => 'drupal_shared_tables.',
'sessions' => 'drupal_shared_tables.',
'users' => 'drupal_shared_tables.',
);
?>
NoteNoteNoteNote the all important trailing dot on the end of drupal_shared_tables – This is very much
required! This is pre-pending table name info to Drupal's default table name, so the dot is required
or Drupal will try to select
drupal_site_1.drupal_shared_tablesauthmap
Instead of the desired
drupal_shared_tables.authmap

Do the same for /sites/site2/settings.php, but with $db_url set to drupal_site2.
Now login as the super user on both sites separately (http://site1/user or http://site2/user)
Using the credentials you entered when you installed site1, give them both different settings,
modules, permissions and content but use the same user credentials. Moreover, if you create a
user on site1, you will see them in users in site2, but with an entirely independent set of
permissions you can decide on a site level.
Now for the shared logins. Download and unzip the Single Sign On module in to
/sites/all/modules.
Enable the Single Sign On Controller module on the site you want to use as the master for
logins (the controller) - in this case, site1. Enable the Single Sign On Client module on all other
sites, for this example just site2.
Then IMMEDIATELY add the following line to settings.php for both sites or you will get
PHP errors:
<?php
# Single Sign On settings:
$conf['session_inc'] = 'sites/all/modules/sso/session.singlesignon.inc';
?>
Copy and paste the Controller information on site1 (found at admin/settings/singlesignon-
controller) over to the Client settings on site2 (go to admin/settings/singlesignon-client). Save
settings on site2 and logout of both sites.
Go to http://site1/user and login. Now go to http://site2. You should stay logged in. Logout
again and see you are logged out in both locations. Reverse it so you login on site2 and visit
site1.

Not all languages are available for every version of Drupal, but if the one required in the site is
available, follow these steps to install Drupal in your language:
Download the language file from the translation server.
Create a directory named translations inside the directory of the profile you will be using. This
is most likely inside profiles/standard.
Move the downloaded .po file inside the translations folder you just created.
Install Drupal as per usual by visiting www.somesite.com/install.php.
AutomatingAutomatingAutomatingAutomating installation and updatesinstallation and updatesinstallation and updatesinstallation and updates
Once you start to add modules and a theme to the site, downloading and keeping translations
updated manually will be very complex and tiring. It is suggested that instead you start off with
the Localized Drupal installation profile or adapt the Localization update module to keep yourself
updated.
