centos7更换YUM源为163源

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

yum install -y wget

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

解决：修改文件/usr/bin/yum、/usr/libexec/urlgrabber-ext-down头中相应python为#!/usr/bin/python2.7
