由于CentOS Linux 8已达到生命周期结束，自2021年12月31日后不再接收官方开发资源。要更新CentOS，需将镜像更改为vault.centos.org。解决方案是执行一系列命令来修复yum下载metadata失败的问题。

来自官方解释：

CentOS Linux 8 had reached the End Of Life (EOL) on December 31st, 2021. It means that CentOS 8 will no longer receive development resources from the official CentOS project. After Dec 31st, 2021, if you need to update your CentOS, you need to change the mirrors to vault.centos.org where they will be archived permanently.

解决方案：依次执行以下语句

cd /etc/yum.repos.d/
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
yum update
