linux修改yum源鏡像源

修改CentOS默認yum源為國內yum鏡像源

1、首先備份系統自帶yum源配置文件/etc/yum.repos.d/CentOS-Base.repo（備份前建議先安裝wget，yum install wget）

[root@localhost ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、進入yum源配置文件所在的文件夾

[root@localhost ~]# cd /etc/yum.repos.d/

3、下載163的yum源配置文件到上面那個文件夾內

CentOS7

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

CentOS6

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

CentOS5

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS5-Base-163.repo

4、運行yum makecache生成緩存

[root@localhost yum.repos.d]# yum makecache

至此，操作全部完成。

5、這時候再更新系統就會看到以下mirrors.163.com信息

[root@localhost yum.repos.d]# yum -y update
已加載插件：fastestmirror, refresh-packagekit, security
設置更新進程Loading mirror speeds from cached hostfile
* base: mirrors.163.com
* extras: mirrors.163.com
