中科大（http://centos.ustc.edu.cn/）的镜像站里面有Centos 6.0 镜像了。

 

先备份一下/etc/yum.repos.d/CentOS-Base.repo

#mv /etc/yum.repos.d/CentOS-Base.repo/etc/yum.repos.d/CentOS-Base.repo.bak

 

然后把/etc/yum.repos.d/CentOS-Base.repo文件改为

# 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.

更改一下源的路径就行了。现在可以更新Centos 6.0了。
