centos6和centos7初始化脚本

刚拿到一台机器的确很兴奋，但是和它交流后你会发现他还没准备好，你拿他没办法，只能一样要的教，这里我给出拉网上借鉴的初始化脚本centos6和centos7的shell，附件目录我还是为大家上传到百度云吧，下面就是展示一下思路。

#!/bin/bash
#author jim.zhong
#this script is only for CentOS 6
#check the OS

#——先对系统进行判断，如果是Cent OS 64位，就继续运行。
#——先将系统的安装源设置为网易的（网易的安装源算是国内比较稳定的）
#——安装epel的源和rpmforge的源，利用第三方的源来让yum安装起来更方便
#——更新软件
#——设置为周期进行时间同步（跟国家授时中心的服务器进行时间同步）
#——将系统同时打开的文件个数增大
#——disable = 将ctrl将ctrl alt delete键进行屏蔽，防止误操作的时候服务器重启
#——关闭selinux
#——禁用GSSAPI来认证，也禁用DNS反向解析，加快SSH登陆速度
#——优化一些内核参数
#——调整删除字符的按键为backspace（某些系统默认是delete）
#——打开vim的语法高亮
#——取消生成whatis数据库和locate数据库
#——关闭没用的服务
#—— disable = 关闭IPv6


platform=`uname -i`
if [ $platform != "x86_64" ];then 
echo "this script is only for 64bit Operating System !"
exit 1
fi
