centos redhat
一般163的源比較好用
1，進入yum源配置目錄
cd /etc/yum.repos.d
2，備份系統自帶的yum源
mv CentOS-Base.repo CentOS-Base.repo.bk
下載163網易的yum源：
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
3，更新玩yum源後，執行下邊命令更新yum配置，使操作立即生效
yum makecache
4，除了網易之外，國內還有其他不錯的yum源，比如中科大和搜狐的，大家可以根據自己需求下載
中科大的yum源：
wget http://centos.ustc.edu.cn/CentOS-Base.repo
sohu的yum源
wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
理論上講，這些yum源redhat系統以及fedora也是可以用 的

# The mirror system uses the connecting IP address of the client and the
