第1步

备份yum配置文件，修改yum配置文件。
cp /etc/yum.repos.d/CentOS-Base.repo CentOS-Base.repo_bak

vi /etc/yum.repo.d/CentOS-Base.repo

可以用中科大(ustc)yum源，也可以用上海交大(sjtu)yum源，两者只能选一个。

用下面的内容覆盖CentOS-Base.repo就行了。
#中科大(ustc)yum源，http://centos.ustc.edu.cn/centos/5/就是最新的，

#也可以设置成http://centos.ustc.edu.cn/centos/5.5/
