centos 6.0 yum更新源

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

 

更换源前做好备份，主要是源文件，以及RPM公匙文件
/ect/yum.conf yum配置文件
/etc/yum.repos.d/ repo文件,源站点
/etc/pki/rpm-gpg/ RPM公匙文件

然后登录网站http://mirrors.163.com 或者 http://mirrors.sohu.com，

查看feoora那行的帮助，里面有说明操作。

然后

删除缓存 从新更新
yum clean all
yum makecache

还可以自动添加高速源
安装yum-plugin-fastestmirror(自动挑选快的镜像站)
yum install yum-fastestmirror
注:确定/etc/yum.conf中的plugins=1

 

 

# 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.
