前些天，在不知道网站是因为GFW被k的情况下，傻傻的重装系统，结果vps一样不能连通。后经vps提供商更换ip后一切正常，在这过程中，也有点收获，发现centos修改成网易163的源居然还有这样简单的方法，真后悔没早点知道，我自己还去慢慢在vi下输入网址，真是浪费时间。下面就是最快速度的修改成网易163源的办法。（网易镜像的帮助文件，我当时真没看到，大家自己去看下吧），其实大家可以去安装yum-fastestmirror，大家自行google用法，我的设定之后，匹配的是清华的源，第一次用清华的源，好激动呀。
复制代码
代码如下:
#mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup //先备份原来的设置，做什么修改之前都要有的习惯
CentOS-5

代码如下:
# wget http://mirrors.163.com/.help/CentOS5-Base-163.repo -O /etc/yum.repos.d/CentOS-Base.repo
