为CentOS Stream 9配置镜像

考虑到国际网络访问体验不佳，可以将CentOS Stream 9的安装源配置为国内镜像。建议使用清华大学的镜像站点，可以在这里找到其中关于CentOS Stream 9的镜像配置说明。

配置步骤

可遵照以下步骤进行配置：

  1. 备份现有的安装源配置文件：
    Terminal window
    sudo cp /etc/yum.repos.d/centos.repo /etc/yum.repos.d/centos.repo.backup
    sudo cp /etc/yum.repos.d/centos-addons.repo /etc/yum.repos.d/centos-addons.repo.backup
  2. 使用下面的内容来替换掉centos.repo文件中的所有内容（这些内容可以在上述说明页面中找到）：
    centos.repo
