CentOS修改yum源

CentOS修改yum源

注意:如果你当前登录用户是root用户,则把以下所有命令前面的sudo去掉,否则可能无法执行。

备份原配置文件

进入yum源配置目录:

cd /etc/yum.repos.d

如果没有先安装wget:

sudo yum install wget

修改yum源,就是修改CentOS-Base.repo的内容,所以我们要先备份一下原来的:

sudo mv CentOS-Base.repo CentOS-Base.repo.backup

下载新配置文件

然后用wget下载国内的yum源(即CentOS-Base.repo文件),新的在哪呢?目前国内主要有三个yum源:
