CENTOS7更换YUM源为163源

访问地址为:http://mirrors.163.com/.help/centos.html

首先备份源:

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

备份之前的源BASE，进入对应目录。

cd /etc/yum.repos.d/
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
mv CentOS7-Base-163.repo CentOS-Base.repo

刷新YUM的缓存状态：

yum clean all
yum makecache
