学习笔记-更换国内镜像源 - CentOS

前言摘要

#    进提供 目前还在使用的 CentOS 版本及替代版本 RockyOS 的源信息
#    版本涵盖 
        CentOS 7
        RokcyOS 9
        CentOS 8
        CentOS Stream
        CentOS 6
#    镜像源 提供 四个版本，更多源可参考镜像源列表文档
        清华大学 镜像源
        北京大学 镜像源 （因为清华大学不提供RokcyOS源）
        阿里云 镜像源
        校园网联合 镜像源
#    为方便操作，全部采用各个镜像源官方脚本
#    文末，提供了 CentOS 7 及 RockyOS 9 的镜像源一键替换脚本
