1、加载wget环境  yum install wget -y 2、备份本地yum源 mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup 3、下载新的CentOS-Base.repo 到/etc/yum.repos.d/ wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 4、生存缓存 yum clean all yum makecache 5、查看yum源 yum repolist
