修改centos的源

摘要

修改centos的源

首先备份/etc/yum.repos.d/CentOS-Base.repo

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

进入yum源配置文件所在文件夹

cd /etc/yum.repos.d/

下载163或者阿里云的yum源配置文件，放入/etc/yum.repos.d/(操作前请做好相应备份)

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo # 163
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo # centos5
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo # centos6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo # centos7

运行yum makecache生成缓存

yum makecache

更新系统

yum -y update
