Introduction to Rocky Linux

In the bustling landscape of operating systems, Rocky Linux stands tall as a pillar of stability and community-driven innovation. Born from the ashes of CentOS, it has swiftly carved its niche, offering a reliable, 100% bug-for-bug compatible alternative to Red Hat Enterprise Linux (RHEL) for both beginners and seasoned veterans.

This article delves into the world of Rocky Linux, exploring its features, advantages, and disadvantages, while showcasing its diverse use cases and solidifying its position as a formidable force in the open-source world.

History of Rocky Linux

Rocky Linux emerged in response to the CentOS project’s strategic shift, which transitioned CentOS Linux from a downstream, binary-compatible rebuild of Red Hat Enterprise Linux (RHEL) to CentOS Stream, a rolling-release distribution closely tied to RHEL development. This move left a void for users seeking a stable and free RHEL alternative. In response, Gregory Kurtzer, one of the original co-founders of CentOS, initiated the Rocky Linux project in December 2020, aiming to provide a community-driven, enterprise-ready Linux distribution.
