下面是一个rac搭建时候的一个环境自动部署脚本，这个脚本可以自动帮你完成安装数据库需要的包，创建oracle,grid用户，并且配置环境变量，已经配置操作系统参数，大部分工作都可以完成，可以根据自己需要修改该脚本。该脚本运行选择（2） ios，指定.iso镜像文件的绝对路径就可以自动部署环境了（.ios文件需要你手动上传到服务器上面）。（该脚本可以根据自己需要来修改）

 Please insert the os install Disc or upload the iso.
Where is your operation system installation media?
1) dvd Disc
2) iso

Where is the iso?(in absolute path,e.g., /u01/rhel-server-6.4-x86_64-dvd.iso)/u01/rhel6.4.iso

记住这里将服务器上的镜像文件位置写上，后面环境就自动部署了。
