修改 CentOS 默認 yum 源為 mirrors.163.com
- 首先備份系統自帶yum源配置文件/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
- 進入yum源配置文件所在的文件夾
[root@localhost ~]# cd /etc/yum.repos.d/
- 下載163的yum源配置文件到上面那個文件夾內
`[root@localhost yum.repos.d]``# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo`
- 運行yum makecache生成緩存
[root@localhost yum.repos.d]# yum makecache
- 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
