Linux系统国内镜像站点

一，更换说明

第一步 备份 如centos， mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
第二步 替换，如centos7替换网yum源，运行 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo #centos7
第三步 生成新缓存，如centos，运行 yum clean all && yum makecache

二，常用系统更换脚本
