CentOS配置YUM源（163、搜狐）

CentOS自带的YUM源下载速度太慢，一般都换成国内的YUM源，一般网易的是比较快的，下载速度可达到700/S左右，而且更新速度快。正题：更新方法如下：先进入yum源配置目录
cd /etc/yum.repos.d
备份系统自带的yum源
mv CentOS-Base.repo CentOS-Base.repo.save
下载yum源
163的yum源：
wget http://mirrors.163.com/.help/CentOS-Base-163.repo
sohu的yum源
wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
更新玩yum源后，建议更新一下，使操作立即生效
yum makecache
