When working with your CentOS server, you may find yourself in a position where you need to remove installed software packages. This may be the result of software no longer being needed for a given project, or it may be due to conflicts with other software that is installed. A group of software packages is generally contained within what is called a repository.

While it is fairly simple to delete repositories in CentOS, the process does require the use of a command-line interface. As such, it is only recommended to perform the steps in this article if you are comfortable with command-line operations. In this article, we will outline how to delete an installed EPEL repository.

Note that you will require root access in order to use these directions.

Delete Repos

  1. First, connect to your CentOS server with root access via SSH.
  2. Next, search for the package name installed by executing the following rpm command:
    rpm -qf /etc/yum.repos.d/epel.repo epel-release-6-8.noarch
  3. Once you’ve found the package name, remove the packages and repos with the following yum command:
    yum remove epel-release
  4. Finally, it is a good idea to run the following command to clear any cached data regarding the installed packages as this can take up a large amount of disk space.
    yum clean all
