使用说明

首先备份CentOS-Base.repo

1. mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

复制代码

下载对应版本的CentOS-Base.repo, 放入/etc/yum.repos.d/

这是CentOS 5的:

1. wget -O CentOS-Base.repo https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/centos?codeblock=1

复制代码

3. # The mirror system uses the connecting IP address of the client and the
   
4. # update status of each mirror to pick mirrors that are updated to and
   
5. # geographically close to the client.  You should use this for CentOS updates
   
6. # unless you are manually picking other mirrors.
   
7. #
   
8. # If the mirrorlist= does not work for you, as a fall back you can try the
