#建议Oracle所作分区（本例为/）至少10G
2、配置YUM（需要上公网或架设内网服务器）
[root@stone ~]# cd /etc/yum.repos.d/
[root@stone yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

3、安装所需软件包
[root@stone ~]# cat ora_software1.txt
binutils*
compat-libstdc++*
elfutils-libelf*
elfutils-libelf-devel*
elfutils-libelf-devel-static*
gcc*
gcc-c++*
glibc*
glibc-common*
glibc-devel*
glibc-headers*
kernel-headers*
ksh*
libaio*
libaio*
libgcc*
libgomp*
libstdc++*
libstdc++-devel*
make*
sysstat*
unixODBC*
unixODBC-devel*
[root@stone ~]# cat ora_software1.txt | xargs yum install -y
4、建立oracle所需组和用户
[root@stone ~]# groupadd oinstall
[root@stone ~]# groupadd dba
[root@stone ~]# useradd -g oinstall -G dba oracle
[root@stone ~]# passwd oracle
Changing password for user oracle.
New password:
BAD PASSWORD: it is too simplistic/systematic
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
5、设置安装目录
[root@stone ~]# mkdir -p /u01/oraInventory
[root@stone ~]# chown -R oracle:oinstall /u01/
[root@stone ~]# chmod -R 775 /u01/
将第4步和第5步做成脚本：
[root@stone ~]# cat ora_user_dir.sh
#!/bin/bash
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
echo "123456" | passwd --stdin oracle
mkdir -p /u01/oraInventory
chown -R oracle:oinstall /u01/
chmod -R 775 /u01/
[root@stone ~]# sh ora_user_dir.sh
Changing password for user oracle.
passwd: all authentication tokens updated successfully.
6、设置环境变量
[root@stone ~]#xhost +
[root@stone ~]# su - oracle
[oracle@stone ~]$ export ORACLE_BASE=/u01/app/oracle
7、解压安装包
[oracle@stone ~]$ unzip /mnt/hgfs/software/linux.x64_11gR2_database_1of2.zip
[oracle@stone ~]$ unzip /mnt/hgfs/software/linux.x64_11gR2_database_2of2.zip
[oracle@stone ~]$ ls
database
