date：2018-04-28 13:33:41 緩存

一、備份

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

二、下載新的CentOS-Base.repo 到/etc/yum.repos.d/

CentOS 5 （目前已經停用了，無效）post

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

CentOS 6flex

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

CentOS 7阿里雲

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

三、以後運行yum makecache生成緩存

yum clean allspa

yum makecachecode

四、查詢htm

yum repolistblog

五、自動修改yum源腳本

#!/bin/bash
mv /etc/yum.repos.d/* /mnt
a=`cat /etc/redhat-release |awk '{print $3}'|awk -F . '{print $1}'`
if [ $a == 6 ];then
   wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
else
   wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
fi
yum clean all
yum makecache
