How to Enable and Install Third Party Packages Using EPEL Repository on CentOS/RHEL
In this article we shall try to learn, how to add EPEL Repository for Linux. EPEL (Extra Package for Enterprise Linux) is an open source and free community based repository from the Fedora community team which provides high quality and good add-on software’s for Linux distributions. It has Red Hat Enter Linux, CentOS, Scientific Linux and most of the repositories which are maintained by the Fedora team only.
Why we use EPEL Repositories for Packages
- Provides a lot of open source packages which are installed using yum.
- EPEL repositories are open source and they are 100% free to use.
- There will not be any compatibility issues and they don’t provide any core duplicate packages.
- These are maintained by Fedora team.
To Enable Repository in CentOS/RHEL
We need to download the file using Wget to get the ‘.rpm’ and install using RPM command. As a root user we needed to run the below command.
For Centos 7 or RHEL 7
# wget http://dl.fedoraprokect.org/pub/epl/7/x86_64/e/epel-release-7.6.noarch.rpm # rpm –ivh epelrelease-7-6.noarch.rpm
For Centos 6.x 64-Bit or 32-Bit
32-Bit
# wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm # rpm -ivh epel-release-6-8.noarch.rpm
64-Bit
# wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm # rpm -ivh epel-release-6-8.noarch.rpm
Verifying the EPEL Repo
As the above command will install the EPEL repository in our yum repositories, we can verify that the EPEL repositories are enabled or not by using the below command.
# yum repolist yum repoli Loaded plugins: fastestmirror Determining fastest mirrors epel/metalink | 12 kB 00:00 * base: linux.cc.lehigh.edu * epel: ftp.osuosl.org * extras: mirror.fusioncloud.co * remi-safe: fr.mirror.babylon.network * rpmforge: mirror.lug.udel.edu * updates: centos.mirror.constant.com WandiscoSVN | 951 B 00:00 base | 3.7 kB 00:00 base/primary_db | 4.7 MB 00:00 epel | 4.3 kB 00:00 epel/primary_db | 5.8 MB 00:00 extras | 3.4 kB 00:00 extras/primary_db | 36 kB 00:00 remi-safe | 2.9 kB 00:00 remi-safe/primary_db | 285 kB 00:00 rpmforge | 1.9 kB 00:00 updates | 3.4 kB 00:00 updates/primary_db | 726 kB 00:00 repo id repo name status WandiscoSVN Wandisco SVN Repo 73 base CentOS-6 - Base 6,696 epel Extra Packages for Enterprise Linux 6 - x86_64 12,156 extras CentOS-6 - Extras 60 remi-safe Safe Remi's RPM repository for Enterprise Linux 6 - x86_64 659 rpmforge RHEL 6 - RPMforge.net - dag 245 updates CentOS-6 - Updates 111 repolist: 20,000 As we install the repositories all the yum repositories are located at /etc/yum.repos.d/epel.repo
How to use EPEL Repository
We use the YUM command to search and install the packages. If we want to install MySQL using EPEL repos, we can execute the below command to see if it is available or not
# yum --enablerepo=epel info mysql Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: linux.cc.lehigh.edu * epel: ftp.osuosl.org * extras: mirror.fusioncloud.co * remi-safe: fr.mirror.babylon.network * rpmforge: mirror.lug.udel.edu * updates: centos.mirror.constant.co Installed Packages Name : mysql Arch : x86_64 Version : 5.1.73 Release : 5.el6_6 Size : 2.4 M Repo : installed From repo : base Summary : MySQL client programs and shared libraries URL : http://www.mysql.com License : GPLv2 with exceptions Description : MySQL is a multi-user, multi-threaded SQL database server. MySQL is a : client/server implementation consisting of a server daemon (mysqld) : and many different client programs and libraries. The base package : contains the standard MySQL client programs and generic MySQL files Available Packages Name : mysql Arch : x86_64 Version : 5.1.73 Release : 7.el6 Size : 894 k Repo : base Summary : MySQL client programs and shared libraries URL : http://www.mysql.com License : GPLv2 with exceptions Description : MySQL is a multi-user, multi-threaded SQL database server. MySQL is a : client/server implementation consisting of a server daemon (mysqld) : and many different client programs and libraries. The base package : contains the standard MySQL client programs and generic MySQL files.
To install the MySQL using EPEL repo we needed to run the below command –
Some time the repos are not updated automatically, then we needed to add the repo’s list to our local yum repository, here for demo purpose I am adding MySQL Community edition version 5.6 to our local repository.
# vi /etc/yum. reposes. d/mysql. reports # Enable to use MySQL 5.6 [mysql56-community] name=MySQL 5.6 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
Now we will install the mysql using EPEL repo
# yum --enablerepo-epel install mysql Loaded plugins: fastestmirror Setting up Install Process Loading mirror speeds from cached hostfile * base: linux.cc.lehigh.edu * epel: ftp.osuosl.org * extras: mirror.fusioncloud.co * remi-safe: fr.mirror.babylon.network * rpmforge: mirror.lug.udel.edu * updates: centos.mirror.constant.com Resolving Dependencies --> Running transaction check ---> Package mysql.x86_64 0:5.1.73-5.el6_6 will be updated --> Processing Dependency: mysql = 5.1.73-5.el6_6 for package: mysql-server-5.1. 73-5.el6_6.x86_64 ---> Package mysql.x86_64 0:5.1.73-7.el6 will be an update --> Processing Dependency: mysql-libs = 5.1.73-7.el6 for package: mysql-5.1.73-7 .el6.x86_64 --> Running transaction check ---> Package mysql-libs.x86_64 0:5.1.73-5.el6_6 will be updated ---> Package mysql-libs.x86_64 0:5.1.73-7.el6 will be an update ---> Package mysql-server.x86_64 0:5.1.73-5.el6_6 will be updated ---> Package mysql-server.x86_64 0:5.1.73-7.el6 will be an update --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Updating: mysql x86_64 5.1.73-7.el6 base 894 k Updating for dependencies: mysql-libs x86_64 5.1.73-7.el6 base 1.2 M mysql-server x86_64 5.1.73-7.el6 base 8.6 M Transaction Summary ================================================================================ Upgrade 3 Package(s) Total download size: 11 M Is this ok [y/N]:
By using the EPEL, we can install the trusted and safe Third party packages from the EPEL repository on CentOS / RHEL (Red Hat Enterprises Linux)
