How To Add, Enable And Disable A Repository In Linux
Many of us using yum package manager to manage package installation, remove, update, search, etc, on RPM based system such as RHEL, CentOS, etc,.
Linux distributions gets most of its software from distribution official repositories. The official distribution repositories contain good amount of free and open source apps/software’s. It’s readily available to install and use.
RPM based distribution doesn’t offer some of the packages in their official distribution repository due to some limitation and proprietary issue. Also it won’t offer latest version of core packages due to stability.
To overcome this situation/issue, we need to install/enable the requires third party repository. There are many third party repositories are available for RPM based systems but only few of the repositories are advised to use because they didn’t replace large amount of base packages.

This can be done on RPM based system such as RHEL, CentOS, OEL, Fedora, etc,.
- Fedora system uses “dnf config-manager [options] [section …]”
- Other RPM based system uses “yum-config-manager [options] [section …]”
How To List Enabled Repositories
Just run the below command to check list of enabled repositories on your system.
For CentOS/RHEL/OLE systems
# yum repolist
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
repo id repo name status
base CentOS-6 - Base 6,706
extras CentOS-6 - Extras 53
updates CentOS-6 - Updates 1,255
repolist: 8,014
For Fedora system
# dnf repolist
How To Add A New Repository In System
Every repositories commonly provide their own .repo file. To add such a repository to your system, run the
following command as root user. In our case, we are going to add EPEL Repository and IUS Community Repo, see below.
There is no .repo files are available for these repositories. Hence, we are installing by using below methods.
For EPEL Repository , since it’s available from CentOS extra repository so, run the below command to install it.
# yum install epel-release -y
For IUS Community Repo , run the below bash script to install it.
# curl 'https://setup.ius.io/' -o setup-ius.sh
# sh setup-ius.sh
If you have .repo file, simple run the following command to add a repository on RHEL/CentOS/OEL.
# yum-config-manager --add-repo http://www.example.com/example.repo
Loaded plugins: product-id, refresh-packagekit, subscription-manager
adding repo from: http://www.example.com/example.repo
grabbing file http://www.example.com/example.repo to /etc/yum.repos.d/example.repo
example.repo | 413 B 00:00
repo saved to /etc/yum.repos.d/example.repo
For Fedora system, run the below command to add a repository.
# dnf config-manager --add-repo http://www.example.com/example.repo
adding repo from: http://www.example.com/example.repo
If you run yum repolist command after adding these repositories, you can able to see newly added repositories. Yes, i saw that.
Make a note: whenever you run “yum repolist” command, that automatically fetch updates from corresponding repository and save the caches in local system.

How To Enable A Repository In System
When you add a new repository by default it’s enable the their stable repository that’s why we are getting the repository information when we ran “yum repolist” command. In some cases if you want to enable their Testing or Dev or Archive repo, use the following command. Also, we can enable any disabled repo using this command.
To validate this, we are going to enable epel-testing.repo by running the below command.
# yum-config-manager --enable epel-testing

If you want to enable multiple repositories at once, use the below format. This command will enable epel, epel-testing, and ius repositories.
# yum-config-manager --enable epel epel-testing ius
For Fedora system, run the below command to enable a repository.
# dnf config-manager --set-enabled epel-testing

For Fedora system, run the below command to enable a repository.
# dnf config-manager --set-disabled epel-testing
Alternatively this can be done by editing the appropriate repo file manually. To do, open the corresponding repo file and change the value from enabled=0
to enabled=1 (To enable the repo) or from enabled=1 to enabled=0 (To disable the repo).
