How to Install the ELRepo Repository on RHEL 6/7/8 and CentOS 6/7/8

ELRepo stands for Enterprise Linux Repository.

ELRepo is a community repository for Enterprise Linux distributions, including Red Hat, CentOS and other derivatives.

ELRepo is a CentOS community-approved third-party RPM repository that focuses primarily on hardware-related packages to enhance your experience with Enterprise Linux.

This includes file system drivers, graphics drivers, network drivers, sound drivers, webcam, video drivers and the latest kernel.

All ELRepo packages are built against the RHEL kernel, and are compatible with the Redhat derivatives who maintain compatibility with the RHEL kernel.

Why should use ELRepo?

Enterprise Linux provides long-term support by maintaining its stability, which is why the latest hardware is not supported in the distribution kernel.

If some of your hardware is not detected, installing kmod driver packages from ELRepo may fix your problem.

kmod is a set of tools to handle common tasks with Linux kernel modules like insert, remove, list, check properties and resolve dependencies.

You can see all the available packages of ELRepo by going to the following link

ELRepo Repository Contents

ELRepo has four channels. Browse the contents of each channel using the appropriate name with the yum command.

  • elrepo: This is the main channel and is enabled by default. It should be safe to run a ‘yum update’ with this repository channel enabled.
  • elrepo-extras: The elrepo-extras channel provides packages and their dependencies that replace/update RHEL distribution packages.
  • elrepo-testing: The elrepo-testing channel provides packages yet to be released to the main channel and is disabled by default.
  • elrepo-kernel: The elrepo-kernel channel provides both the long-term support kernels and the latest stable mainline kernels. It’s disabled by default.

If you are looking for other third party yum repositories for RPM based systems to extend and enhance the functionality of Enterprise Linux, go to the following link.
