如何更换安装Linux源？

yum，全称“Yellow dog Updater, Modified”，是一个专门为了解决包的依赖关系而存在的软件包管理器。类似于我们软件管家一样，一键安装软件并解决环境依赖关系，而且也可以管理并一键卸载。

执行以下脚本，自动根据您的系统进行全自动化操作换YUM

  1. wget http://mirrors.qingyunl.com/Shell/vps/yum_apt_select.sh;bash yum_apt_select.sh

1、CentOS7
①、先备份当前的安装源目录

  1. \cp  -rp /etc/yum.repos.d/    /etc/yum.repos.d_back

②、注释mirrorlist

  1. sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*.repo

③、将baseurl的地址指向清华源

  1. sed -i 's|#baseurl=http://mirror.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn|g' /etc/yum.repos.d/CentOS-*.repo

替换后，执行下面命令进行生成软件包的缓存
