Red Hat free repositories

You need a subscription to access Red Hat sources servers.

Fortunately, you can access most of the packages freely with other sources.

Note: Edit scripts to match your RHEL version! You can view it with hostnamectl.

EPEL repository

EPEL is a repository targetted at Fedora users. It can be used with the following systems:

Red Hat Enterprise Linux (RHEL)
CentOS
Scientific Linux
Oracle Linux

Install via package manager

sudo yum install epel-release

Install manually

If the package was not found using your package manager, you can install it manually.

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum install ./epel-release-latest-*.noarch.rpm

CentOS

To access the majority of the packages for free you can use CentOS ones.

Create a new repository location.

nano /etc/yum.repos.d/CentOS-Base.repo

Paste the following content.

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
