以下为修改Centos6.5的yum源:

1. 备份原镜像文件,便于后期恢复

[root@keepmydream ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

 

2.下载新的CentOS-Base.repo 到/etc/yum.repos.d/ 

Centos5地址:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

Centos6地址:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

Centos7地址:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

 

3. 清除缓存

yum clean all

 

4. 生成缓存

yum makecache
