Solution

I went around Du Niang today and couldn't solve this problem, but I went to Ali's mirror station to look around, and I found that he had an article.

I see this is not the solution

A command to solve your worries

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
