CentOS8阿里新镜像源【解决阿里云路径弃用问题】

方案1（脚本中会清空yum.repo.d内的文件）

==防盗标识：本文源文地址，未授权禁止转载https://blog.csdn.net/weixin_44331765/article/details/123068623

1. 创建一个脚本文件cetos.sh
2. 写入以下内容
3. 执行bash centos.sh即可

   
   #!/bin/bash
   cp -r /etc/yum.repo.d /etc/yum.repo.d.bak
   rm -rf /etc/yum.repo.d/*
   cat >> /etc/yum.repo.d/CentOS-Base.repo << EOF
   # CentOS-Base.repo
   #
   # The mirror system uses the connecting IP address of the client and the
   # update status of each mirror to pick mirrors that are updated to and
   # geographically close to the client.  You should use this for CentOS updates
   # unless you are manually picking other mirrors.
   #
   # If the mirrorlist= does not work for you, as a fall back you can try the 
   # remarked out baseurl= line instead.
   #
   #

方案2替换原有的路径

1. 手动替换：

替换CentOS-Linux-AppStream.repo中的内容
1. 注释#mirrorlist=xxxxx
2. 启用baseurl=xxx，并把baseurl中的http路径修改为：baseurl=http://mirrors.aliyun.com/centos-vault/8.5.2111/extras/$basearch/os/
3. 同理替换CentOS-Linux-BaseOS.repo中的mirrorlist=xxx和baseurl并把地址换了即可

2. 脚本执行：执行方法同1
   centos.sh文件内容替换为

#!/bin/bash
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
cat >> /etc/yum.repo.d/CentOS-Base.repo << EOF
	# CentOS-Base.repo

	# unless you are manually picking other mirrors.
	#
	# If the mirrorlist= does not work for you, as a fall back you can try the 
	# remarked out baseurl= line instead.
