Step 1

Backup

mv redhat.repo redhat.repo_bak

Switch to the source file directory

cd /etc/yum.repo.d/

Aliyun mirror Download the Aliyun CentOS 8 repository

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo

---- If you do not have wget, use curl
curl -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo

163 mirror

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

---- If wget is not installed, download with curl
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

Step 2

Change the default configuration

# Modify the following two configuration files and change the value of enabled to 0
vi /etc/yum/pluginconf.d/product-id.conf
vi /etc/yum/pluginconf.d/subscription-manager.conf

Clean up

# Clear the yum cache
yum clean all
# Rebuild the yum cache
yum makecache

Method 2

Create the repo file

Go to the /etc/yum.repo.d/ directory and create

vi CentOS-stream-8.repo

Copy and paste the following content
