Add a web server
- 1. < Web Server />
- 2. What is a Web Server? • A powerful system which stores, processes and delivers web content over a network which could be either local network as intranet or internet. A typical PC (Desktop or Laptop) + IIS Server (Software) = Web Server
- 3. How it works…? Web Pages Web Server Internet Client • It uses the client/server architecture and HypertextTransfer Protocol (HTTP) for communication.
- 4. Client request consists of several steps: Web Browser Web Server File System 1. User Requests document • User requests document. • Request message is parsed. • Verify that request is authorized. • URL in the request is associated with a file document. • Construct and transmit the response. How it works…? 2.Web Server looks For document in the file system
- 6. Server can generate the response in different ways: 3.Web Server retrieves Document from file system • Server can simply retrieve the file associated with the URL and returns the content to the client. • Server can invoke a script that communicates with other servers or back-end database to construct the response message. How it works…? Web Browser Web Server File System 4.Web Server returns document data to web browser
- 8. Use of Web Server? • Multiple website • Multiple websites can be hosted on single web server with different port numbers assigned to each web site. • Server side scripting • Server-side scripting language PHP would enhance business by producing dynamic contents. • Security • SSL (Secure Socket Layer) would add one more layer of security by encrypting sensitive information. • Failover • IIS offers in-depth diagnostic tools such as failed request tracing, request monitoring and runtime data.
- 9. Business Goal • Web server provides server side coding capability. • It provides high availability with no downtime to end clients. • The web site can be running 24x7 including weekends and off-office hours. • By implementing Webserver, the server side deployments helps in performance. • Troubleshooting with the application is determined based on the logs from the Web server.
- 10. Web Server Setup Environment • Windows 7 operating system • IIS Server 7 • Web Content:WordPress software package (v4.0)
- 11. Network Diagram • A network diagram is a graphical representation of any network. • It’s a small structure of computers and network devices (routers, modem, Ethernet etc.) • It is a sequence of steps.

- 13. Design Features • Configure IIS (Internet Information Services)Web server on Windows 7 operating system. • IIS is an extensible web server created by Microsoft. • It is tightly integrated with Windows operating system. • It supports many protocols such as HTTP, HTTPS, FTP, FTPS, SMTP and NNTP.
- 14. Design Features • Configure PHP (server-side language) to provide the capability to create dynamic content. • PHP is a server side scripting language which can be used to develop web applications. • The PHP database connection script connects to MySQL database to store and retrieve website information. • The generated content would be passed to the web server for display to the user.
- 15. Design Features • Configure MySQL (a database server) to provide the capability to store content. • MySQL is an open source relational database management system. • It is one of the most popular databases and delivers reliable, high performance web-based and embedded database applications. • It is scalable and flexible and used by large corporations. • It is known for its performance, cross platform compatibility, cost and security. • Database system would provide access to database to store and organize site data and information.
- 16. Design Features • Design company’s website usingWordPress and host it on the web server. • WordPress is a Content Management System, use to create beautiful websites. • Free to use and based on PHP and MySQL. • Easy to use and maintain.WordPress admin panel can be used to easily add, update and delete content to the website. • Setup the windows firewall to secure the website from malicious attacks and safety. • A firewall is a system that prevents unauthorized access to or from a private network. • By default windows firewall block all the connections including HTTP port 80 and HTTPS 443.
- 17. Design Features • Setup SSL • Intermediate layer between theTransport andApplication layer. • Establishes secure connection between peers. • Uses secure connection to transfer data from sender to recipient. Transport Layer Secure Socket Layer Network Layer HTTP SMTP POP3 80 25 110 HTTPS SSMTP SPOP3 443 465 995
- 18. Standards & Protocols • HTTP (Hypertext transfer protocol) • HTTP is used between two computers to transfer text from hypertext links. • HTTP works as request-response protocol between the server and user’s browser. • Default port for HTTP is 80.
- 19. Standards & Protocols • HTTPS (Hypertext transfer protocol over Secure Socket Layer) • Secure communication by encrypting sensitive data like login details, credit card details. • The connection from client-server and server-client is secured using 128-bit SSL encryption. • To enable this protocol, web server requires an SSL Certificate. • Default Port for HTTPS is 443.
- 20. Implementation Steps • Installed IIS web server • Installed PHP & MySQL • Downloaded WordPress Steps 1,2,3 • Added website in IIS and bound it to HTTP port 80. • Added content to WordPress. Steps 4,5 • Configure Firewall • Installed SSL certificate to secure theWordPress admin and bound it to HTTPS on port 443. Steps 6,7
- 21. Install IIS Server • Go to Control Panel->Programs and Features • In “TurnWindows features on or off”, select Internet Information Services and it will install IIS with default features. • It will create inetpub/wwwroot directory. • Go to browser and type http://localhost to verify that IIS server has been installed.
- 22. Install PHP • Download PHP installer for windows. • Run the installation setup and follow the process. • Verify that PHP is configured and running on the machine. • Create a file info.php and put it in inetpub/wwwroot • File content is <?php echo phpinfo(); ?> • Browse http://localhost/info.php it will show PHP information page.
- 23. Install MySQL • Download MySQL installer for windows. • Run the installation setup and follow the process. • After installation, connect to MySQL server.
- 24. Download WordPress • DownloadWordPress • Extract the zip file into inetpub/wwwroot/IT640 • Open IIS manager and bind the WordPress on HTTP port 80. • Create Database using MySQL database manager.
- 25. Install WordPress • Browse http://localhost and it will load theWordPress installation page as HTTP port 80 binds toWordPress Directory. • Follow the installation process. • After installation it will load the WordPress admin page. Once logged in admin can add content.
- 26. Configure Firewall • Go to Control Panel->Windows Firewall (Turn on the windows firewall). • This setting would block all the connections and requests including port 80 and 443. • Add New Rule to allow connection on ports 80 and 443.
- 27. Install SSL • Create a self-signed certificate using IIS server. • Bound the certificate to the abccompany.com hostname, using .NET SDK’s makecert.exe. • After creating the certificate, it becomes available in IIS and is ready to be imported by the website.
- 28. Add hostname • Point local IP address 127.0.01 to abccompany.com, edited /windows/system32/drivers/etc/ hosts file • User can access the website at http://abccompany.com instead of http://localhost.
- 29. Secure WordPress admin • Configured theWordPress to strictly use HTTPS while using admin panel and its login. • Browser verifies the hostname from certificate’s “IssuedTo” with the actual host name in the URL. • Most of the browsers show the padlock icon to confirm that identity has been matched, and this secure connection starts with https://abccompany.com
