11g傻瓜安装教程，
准备环境：
首先用root账户登陆系统
获取IP：dhclient
查看内存空间
[root@localhost ~]# grep MemTotal /proc/meminfo
MemTotal: 3863544 kB
Minimum: 1 GB of RAM
Recommended: 2 GB of RAM or more
看操作系统多少位
[root@localhost ~]# uname -m
x86_64
查看swap空间
[root@localhost ~]# grep SwapTotal /proc/meminfo
SwapTotal: 4063228 kB
内存和swap的使用空间
[root@localhost ~]# free
total used free shared buff/cache available
Mem: 3863544 890756 1966144 15500 1006644 2653992
Swap: 4063228 0 4063228
确定可用共享内存的数量
[root@localhost ~]# df -h /dev/shm/
Filesystem Size Used Avail Use% Mounted on
tmpfs 1.9G 0 1.9G 0% /dev/shm
确定/tmp目录中可用的磁盘空间量，至少需要1G
[root@localhost ~]# df -h /tmp
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/rhel-root 36G 3.6G 32G 10% /
确定系统上的空闲磁盘空间量
[root@localhost ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/rhel-root 36G 3.6G 32G 10% /
devtmpfs 1.9G 0 1.9G 0% /dev
tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs 1.9G 13M 1.9G 1% /run
tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup
/dev/sda1 1014M 170M 845M 17% /boot
tmpfs 378M 28K 378M 1% /run/user/0
/dev/sr0 4.4G 4.4G 0 100% /mnt
查看操作系统版本
[root@localhost ~]# cat /proc/version
Linux version 3.10.0-862.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) ) #1 SMP Wed Mar 21 18:14:51 EDT 2018
查看内核版本
[root@localhost ~]# uname -r
3.10.0-862.el7.x86_64
要求：On Oracle Linux 7 with Red Hat Compatible Kernel
3.10.0-54.0.1.el7.x86_64 or later
[root@localhost ~]# uname --all
Linux localhost.localdomain 3.10.0-862.el7.x86_64 #1 SMP Wed Mar 21 18:14:51 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.5 (Maipo)
配置yum源
vim /etc/yum.repos.d/base.repo
[base]
name=base
baseurl=file:///mnt
enable=1
gpgcheck=0
mount /dev/cdrom /mnt
安装Oracle Database 11g Release 2(11.2)所需的软件包
[root@localhost ~]#yum -y install compat-libcap1 compat-libstdc++-33 compat-libstdc++ gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat
确定是否安装了所需的包
[root@localhost ~]# rpm -q compat-libcap1 compat-libstdc++-33 compat-libstdc++ gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat
compat-libcap1-1.10-7.el7.x86_64
package compat-libstdc++-33 is not installed
package compat-libstdc++ is not installed
gcc-4.8.5-28.el7.x86_64
gcc-c++-4.8.5-28.el7.x86_64
glibc-2.17-222.el7.x86_64
glibc-devel-2.17-222.el7.x86_64

libXi-1.7.9-1.el7.x86_64
libXtst-1.2.3-1.el7.x86_64
make-3.82-23.el7.x86_64
sysstat-10.1.5-13.el7.x86_64
建相关的组和用户
root@localhost ~]# groupadd oinstall
[root@localhost ~]# groupadd dba
[root@localhost ~]# usermod -g oinstall -G dba oracle
[root@localhost ~]# id oracle
uid=1000(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)
[root@localhost ~]# passwd oracle --stdin
Changing password for user oracle.
oracle
passwd: all authentication tokens updated successfully.
配置内核参数
[root@localhost ~]# gedit /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
运行sysctl -p使生效
[root@localhost ~]# sysctl -p
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
创建所需目录
[root@localhost ~]# mkdir -p /u01/app/oracle/product/11.2[一般公司都安装在这个目录]
[root@localhost ~]# chown -R oracle:oinstall /u01[所属用户改成oracle，所属组为osinatll，-R是u01下所有的子目录全改]
[root@localhost ~]# chmod -R 775 /u01[上面更改了所属权限，接下来需要更改权限]
复制安装包至虚拟机
[root@localhost ~]# cd /tmp
[root@localhost tmp]# ls
