1、安裝wget下載工具

yum install wget -y

2、進入yum源配置文件

//進入yum配置文件夾
cd /etc/yum.repos.d

//備份之前的配置文件
mv CentOS-Base.repo CentOS-Base.repo.bak

//網易163源
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

//阿里源
wget http://mirrors.aliyun.com/repo/Centos-7.repo

4、設置需要的鏡像源為默認源

//修改指定的yum源為默認yum源
mv /etc/yum.repos.d/Centos-7.repo /etc/yum.repos.d/CentOS-Base.repo

5、清空之前緩存生成新的緩存

//清空緩存
yum clean all
