RHEL7: How to install the ELRepo repository.

Share this link

Presentation

The ELRepo project provides packages for Red Hat Enterprise Linux 7 and its derivatives (CentOS, Scientific Linux). It focuses on hardware related packages (kernels, filesystem drivers, graphics drivers, network drivers, sound drivers, webcam and video drivers).

There is a list of the available packages in the ELRepo repository.

Installation Procedure

To install the ELRepo repository, type:

# yum install -y "http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm"

The ELRepo repository consists of 4 channels:

  • elrepo: this is the main repository; it is enabled by default,
  • elrepo-extras: it provides packages and their dependencies that replace/update RHEL distribution packages; it is disabled by default,
  • elrepo-testing: it offers packages yet to be released to the main channel; it is disabled by default,
  • elrepo-kernel: it contains old and recent kernels; it is disabled by default.

Activation/Deactivation Procedure

To permanently enable a channel (use the –disable option to disable), type:

# yum-config-manager --enable channel

To only enable a channel during a package installation, type:

# yum --enablerepo=channel install package
