sudo cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

sudo vim /etc/yum.repos.d/CentOS-Base.repo

# And comment out all the mirrorlist lines.
# And uncomment all the baseurl lines.
# For CentOS version 8 and below you will also need to change `mirror.centos` to `vault.centos` in the baseurl lines as they are deprecated.

# 就是注释掉mirro 列，打开 baseurl列，然后把mirror.centos都改成 vault.centos。
