解决CentOS7不维护后无法装软件的问题

更新时直接报域名解析错误：

# yum update
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 未知的错误"

使用以下命令更改源设置：

sed -i.bak \
  -e 's|^mirrorlist=|#mirrorlist=|g' \
  -e 's|^#baseurl=http://mirror.centos.org/centos|baseurl=https://vault.centos.org/centos|g' \
  /etc/yum.repos.d/CentOS-Base.repo

https://vault.centos.org/
