适用CentOS7下Oracle database 11g预安装脚本
在执行脚本之前，将CentOS7的iso镜像文件以及数据库的两个zip包（p13390677_112040_Linux-x86-64_*.zip）放入/opt目录即可，此脚本实现环境参数的自动调整以及不能联网时本地YUM源的依赖包安装
#!/bin/bash
#Oracle DataBase 11g preinstall Enviroment
#Usage:Log on as the superuser('root'),and then execute the command
#echo "Now start change HOSTS and backup hosts /etc/hosts.bak"

#echo "#public ip ent0" >>/etc/hosts
#echo "172.16.16.10 orcl" >>/etc/hosts
#echo "change hosts succeed"
