Centos7最小化安装更换yum阿里源

0.安装wget

yum -y install wget

1.首先备份系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2.下载国内yum源配置文件到/etc/yum.repos.d/

阿里源（推荐）：
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

3.清理yum缓存，并生成新的缓存

yum clean all
yum makecache

4.更新yum源检查是否生效

yum update
