EPEL (Extra Packages for Enterprise Linux)

May 31, 2023

What Is Extra Packages for Enterprise Linux?

Extra Packages for Enterprise Linux (EPEL) is a community-driven repository of additional software packages for Enterprise Linux distributions. EPEL was created to address the need for software packages that are not included in the base distribution. These packages provide additional features and capabilities based on the specific needs of a user.

EPEL is maintained and managed by a community of volunteers who are committed to providing high-quality, open source software. The EPEL repository contains a wide range of software packages, including server applications, development tools, system administration utilities, and libraries. Many packages are updated frequently to ensure that they are secure and up-to-date. EPEL also resolves dependencies between packages, making it easier to install and use the software.

To utilize EPEL, users must first enable the EPEL repository on their system, which involves downloading and installing the appropriate package. Once the repository is enabled, users can install software packages from EPEL using their preferred package management tool, such as YUM or DNF.

What Packages and Versions Are Available? 

There are thousands of packages available in the EPEL repository. This vast selection of packages can provide users with additional flexibility and functionality, allowing them to customize their systems to meet their specific needs. Some of the most trusted and widely used packages include:

Git - Git is a popular version control system used for software development. It allows developers to keep track of changes made to their codebase and collaborate with other team members on the same project. Git is highly customizable and flexible, making it a preferred choice for software development teams of all sizes.

Nginx - Nginx is a high performance web server and reverse proxy server. It is designed to handle a large number of concurrent connections and can serve static and dynamic content quickly and efficiently. Nginx is used by many large-scale websites and web applications due to its speed and reliability.

MySQL - MySQL is an open source relational database management system. It is widely used for web development, data analysis, and other applications that require the storage and retrieval of structured data. MySQL is known for its performance, scalability, and ease of use.

PostgreSQL - PostgreSQL is an advanced open source database system. It offers support for complex data types and transactions, making it a preferred choice for enterprise-level applications. PostgreSQL emphasizes reliability and data integrity.

Apache Maven - Apache Maven is a build automation tool used primarily for Java projects. It is designed to simplify the build process and manage project dependencies. Maven is widely used in Java development due to its flexibility and ease of use. 

It is important to exercise caution when installing packages from third-party repositories, including EPEL, as they may not have gone through the same level of testing and verification as official packages. Users should always review the package's documentation, verify its integrity, and ensure that it meets their specific requirements before installing it on their system. 

Enabling Extra Packages for Enterprise Linux

Enabling the EPEL repository is a standard process that can be done using the package manager of Enterprise Linux distribution in use. To enable the EPEL repository, users must download and install the EPEL repository RPM package. Once the installation is complete, they can start using the EPEL repository to search for and install new packages.
