CentOS7 configuration Alibaba Cloud yum source method code

Open the centos yum folder

Enter the command cd /etc/yum.repos.d/

Download the repo file with wget

Enter the command wget http://mirrors.aliyun.com/repo/Centos-7.repo

If the wget command does not work, it means that the wget tool has not been installed. Enter yum -y install wget and press Enter to install it.

The current directory is /etc/yum.repos.d/, and the Centos-7.repo just downloaded is also in this directory
