Note: This article is configured for centos7 of arm32. Do not try other systems or different architectures.

1. First, let's switch to root

su root

2. Enter the directory where the configuration file is located

cd /etc/yum.repos.d/

3. Just in case, it's not necessary to back up first

mv CentOS-Base.repo CentOS-Base.repo.bak

vi CentOS-Base.repo

Replace with the following

# 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.
