Oracle11.2.0.1 install script in Linux-X64-

Before installing Oracle on linux, You need to perform a series of configurations. Manual execution of each environment is slow;
Two scripts are written here for automatic configuration and installation. Currently, the installation is successful on your CentOS6.3 linux template;
It is not tested on other systems. before using it, you must first understand the script, configure a static IP address for the NIC, and modify the IP address before performing the operation;
Scripts are composed of a series of functions in sequence;
