EPEL - Install EPEL on Linux CentOS

The dnf list or yum list command will the repositories you have installed at the beginning of the output. Notice that the EPEL (Extra Packages for Enterprise Linux) repository is not included in the output.

~]$ dnf list | head
 * base: centos.mirrors.tds.net
 * centos-sclo-rh: mirror.den01.meanservers.net
 * centos-sclo-sclo: mirror.den01.meanservers.net
 * extras: centos.mirrors.tds.net
 * updates: mirror.genesishosting.com

 

Likewise, the dnf list installed or yum list installed command can be used to determine if EPEL is installed. If EPEL is not installed, nothing should be returned.

dnf list installed | grep -i epel

 

Or the dnf repolist or yum repolist command can be used.

dnf repolist | grep -i epel

 

And yet another way to know if EPEL is installed is to check the /etc/yum.repos.d directory. Notice in this example that the directory does not contain any EPEL files.

~]$ ll /etc/yum.repos.d/
-rw-r--r--. 1 root root 1664 Apr  7  2020 CentOS-Base.repo
-rw-r--r--. 1 root root 1309 Apr  7  2020 CentOS-CR.repo
-rw-r--r--. 1 root root  649 Apr  7  2020 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root  314 Apr  7  2020 CentOS-fasttrack.repo
-rw-r--r--. 1 root root  630 Apr  7  2020 CentOS-Media.repo
-rw-r--r--. 1 root root 1331 Apr  7  2020 CentOS-Sources.repo
-rw-r--r--. 1 root root 7577 Apr  7  2020 CentOS-Vault.repo
-rw-r--r--. 1 root root  616 Apr  7  2020 CentOS-x86_64-kernel.repo

 

The dnf install or yum install command can be used to install EPEL.

dnf install epel-release

 

Or like this (CentOS 7).

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

 

Or like this (CentOS 8).

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

 

The yum list command should now return something like this.

epel-release.noarch  7-11  @extras

 

Now the /etc/yum.repos.d directory should contain EPEL files.

~]$ ll /etc/yum.repos.d/
-rw-r--r--. 1 root root 1664 Apr  7  2020 CentOS-Base.repo
-rw-r--r--. 1 root root 1309 Apr  7  2020 CentOS-CR.repo
-rw-r--r--. 1 root root  649 Apr  7  2020 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root  314 Apr  7  2020 CentOS-fasttrack.repo
-rw-r--r--. 1 root root  630 Apr  7  2020 CentOS-Media.repo
-rw-r--r--. 1 root root 1331 Apr  7  2020 CentOS-Sources.repo
-rw-r--r--. 1 root root 7577 Apr  7  2020 CentOS-Vault.repo
-rw-r--r--. 1 root root  616 Apr  7  2020 CentOS-x86_64-kernel.repo
-rw-r--r--  1 root root 1050 Oct 31  2020 epel.repo
-rw-r--r--  1 root root 1149 Oct 31  2020 epel-testing.repo

 

By default, in the /etc/yum.repos.d/epel.repo file, where only the "epel" block is enabled. A block can be permanently enabled (1) or disabled (0) by editing the epel.repo file.

[epel]
name=Extra Packages for Enterprise Linux 7 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch
metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch&infra=$infra&content=$contentdir
failovermethod=priority

gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

[epel-debuginfo]

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

[epel-source]

#baseurl=http://download.fedoraproject.org/pub/epel/7/SRPMS

failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
gpgcheck=1

 

Or, a block can be temporarily enabled using the yum install --enablerepo command.

dnf install --enablerepo epel-debuginfo

 

A block can be temporarily disabled using the yum install --disablerepo command.

dnf install --disablerepo epel-debuginfo
