CentOS 6.6 x64 自动化安装Oracle Database 11gR2 RAC脚本

os:CentOS 6.6
hostname:rac11g03,rac11g04
IP: rac11g03 192.108.56.103 192.108.96.103 192.108.26.103
rac11g04 192.108.56.104 192.108.96.104 192.108.26.104
Oracle:11.2.0.4
storage:openfiler 192.108.26.100:3260

说明:
1.centos 6.6已经做了basic安装,ip和主机名已设置.
2.oracle安装文件p13390677_112040_Linux-x86-64_1of7.zip,p13390677_112040_Linux-x86-64_2of7.zip,p13390677_112040_Linux-x86-64_3of7.zip放在rac11g03的/root下,pdksh-5.2.14-30.x86_64.rpm包放在rac11g03的/root下.
3.密码都用的selectshen,可根据自己的需要修改
4.三个网段,192.108.56.0:public,192.108.96.0:private,192.108.26.0:storage
5.以下脚本可以在健壮性和通用性上做一些调整,以用来在开发测试环境中快速部署RAC.
