1、首先備份系統自帶yum源配置檔案/etc/yum.repos.d/centos-base.repo

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

2、進入yum源配置檔案所在的資料夾

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

3、檢視centos系統版本

[root@localhost ~]#lsb_release -a

centos7

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

centos6

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

centos5

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

5、執行yum makecache生成快取

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

6、這時候再更新系統就會看到以下mirrors.163.com資訊

[root@localhost yum.repos.d]# yum -y update

已載入外掛程式:fastestmirror, refresh-packagekit, security

設定更新程序loading mirror speeds from cached hostfile

* base: mirrors.163.com

* extras: mirrors.163.com

* updates: mirrors.163.com
