Setting up a YUM Repository

Update on:
Feb 4, 2023


YUM (Yellowdog Updater, Modified) is a popular open-source package management system used to install, update, and remove packages in Linux distributions such as Fedora, Red Hat Enterprise Linux (RHEL), and CentOS. YUM makes it easier to manage packages by resolving dependencies, downloading packages from a central repository, and installing them. This article will guide you through the process of setting up a YUM repository for your organization or personal use.

Why Set Up a YUM Repository?

A YUM repository is a central location from which you can install packages. By setting up your own repository, you can control which packages are available, improve performance by downloading packages from a local source, and ensure that all your systems have access to the same packages.

There are many reasons why you might want to set up your own YUM repository. For example, you may want to:

  • Keep your systems up to date with the latest packages
  • Store packages that are not available in the default repositories
  • Control which packages are available to your systems
  • Improve performance by downloading packages from a local source


Before you start setting up your YUM repository, you need to have the following:

  • A Linux server with root access
  • Internet connectivity
  • A package management system installed (such as YUM, RPM, or DNF)

Step 1: Install Required Packages

The first step in setting up a YUM repository is to install the required packages. You will need to install the following packages:

  • createrepo
  • httpd

To install these packages, use the following command:

yum install createrepo httpd

Step 2: Create the Repository Directory

Once the required packages are installed, you need to create a directory where the repository will be stored. In this example, we will use the directory /var/www/html/repo.

mkdir /var/www/html/repo

Step 3: Copy Packages to the Repository Directory

Next, you need to copy the packages that you want to include in the repository to the /var/www/html/repo directory.

For example, to copy all the RPM packages in the /var/www/html/repo directory, use the following command:

cp /path/to/packages/*.rpm /var/www/html/repo/

Step 4: Create the Repository Database

Once the packages have been copied to the repository directory, you need to create a database of the packages. The database is used by YUM to determine which packages are available and their dependencies.

To create the repository database, use the following command:

createrepo /var/www/html/repo/

Step 5: Start the Apache Web Server

The next step is to start the Apache web server so that clients can access the repository. To start the Apache web server, use the following command:

systemctl start httpd

Step 6: Configure the YUM Repository

The final step is to configure the YUM repository on the clients. To do this, you need to create a YUM repository configuration file on each client.

The configuration file should contain the following information:

  • The name of the repository
  • The baseurl of the repository
  • The enabled option (set to 1 to enable the repository, or 0 to disable it)

To create the configuration file, open a text editor and create a file with the following contents:

name=My YUM Repository

Save the file as /etc/yum.repos.d/myrepo.repo. Replace “server.example.com” with the hostname or IP address of your YUM repository server.

Step 7: Test the YUM Repository

To test the YUM repository, use the following command on each client:

yum repolist

This command will display a list of all the available repositories, including the one you just created.

To install a package from the YUM repository, use the following command:

yum install <package name>

Replace “<package name>” with the name of the package you want to install.


Setting up a YUM repository can greatly improve the management of packages in your organization or personal use. By having a central location for your packages, you can ensure that all your systems are up to date and have access to the same packages. The steps in this article provide a basic guide to setting up a YUM repository, but you may need to make additional changes based on your specific needs.
