有时候CentOS默认的yum源不一定是国内镜像，导致yum在线安装及更新速度不是很理想。这时候需要将yum源设置为国内镜像站点。国内主要开源的开源镜像站点应该是网易和阿里云了。

修改CentOS默认yum源为mirrors.163.com

1、首先备份系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo

2、进入yum源配置文件所在的文件夹

3、下载163的yum源配置文件到上面那个文件夹内

CentOS7

CentOS6

CentOS5

4、运行yum makecache生成缓存

5、这时候再更新系统就会看到以下mirrors.163.com信息
