This topic describes how to add repositories to different Linux distributions by using
Alibaba Cloud software repositories. Software packages for Linux are often stored
in software repositories. After you add a repository, you can use the package management
tool provided by Linux to search for, install, and update software applications in
the repository.
Background information
Note Both Alibaba Cloud users and non-users have free access to Alibaba Cloud software
repositories. You can go to the
Alibaba Open Source Image Site to obtain the software repository of the Linux distribution.

- If you want to add a software repository that is not from Alibaba Cloud, replace
http://mirrors.aliyun.com/repo/Centos-7.repo
in the preceding commands with the URL of the software repository that you want to
add.
- Run the following command to generate a local cache for faster searching for and installation
of software:
sudo yum clean all && sudo yum makecache
- Run the
sudo yum repolist
command to check whether the software repository is added.
After you add an Alibaba Cloud software repository to CentOS 7, the system displays
the following information.
