首先备份一下原先的yum源，避免出错无法恢复

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

然后修改base.reop源

wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

安装epel.repo源

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

刷新缓存

yum clean all
yum makecache
