修改centos yum源
阿新 • • 發佈：2018-12-10
有時候CentOS預設的yum源不一定是國內映象，導致yum線上安裝及更新速度不是很理想。這時候需要將yum源設定為國內映象站點。國內主要開源的開源映象站點應該是網易和阿里雲了。
修改CentOS預設yum源為mirrors.163.com
1、首先備份系統自帶yum源配置檔案/etc/yum.repos.d/CentOS-Base.repo
| 1 |
[[email protected] ~]# 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
| 1 |
[[email protected] ~]# cd /etc/yum.repos.d/
|
3、下載163的yum源配置檔案到上面那個資料夾內
CentOS7
1[[email protected] yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
CentOS6
| 1 |
[[email protected] yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo |
CentOS5
| 1 |
[[email protected] yum.repos.d]# wget http://mirrors.163.com/.help/CentOS5-Base-163.repo
|
4、執行yum makecache生成快取
| 1 |
[[email protected] yum.repos.d]# yum makecache
|
5、這時候再更新系統就會看到以下mirrors.163.com資訊
| 1 2 3 4 5 6 |
[[email protected] yum.repos.d]# yum -y update
已載入外掛：fastestmirror, refresh-packagekit, security
