清华大学：
中国科技大学：   （推荐，比较快）


1.以root用户进入CentOS系统。
[root@xuxy ~]# cd /etc/yum.repos.d
2.备份repo
[root@xuxy yum.repos.d]# mv CentOS-Base.repo  CentOS-Base.repo.bak
3.建立新的CentOS-Base.repo文件：（以CentOS 5.2为例）
[root@xuxy yum.repos.d]#vi CentOS-Base.repo
内容如下（以中国科技大学的yum源为例）：
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#
