Rocky Linux: A Comprehensive Overview
Introduction
Rocky Linux is an open-source enterprise-level operating system designed to be a community-driven alternative to CentOS. Named after one of the co-founders of CentOS, Rocky McGaugh, this Linux distribution emerged in response to Red Hat’s decision to shift CentOS from a stable release to a rolling-release model with CentOS Stream. Since its inception, Rocky Linux has garnered significant attention and support from users and developers alike, solidifying its position in the Linux ecosystem.
History
Rocky Linux was announced in December 2020 by Gregory Kurtzer, one of the original co-founders of the CentOS project. The goal was to create a robust, production-ready platform that mirrors the stability and reliability of CentOS before the transition to CentOS Stream. In June 2021, the first stable release of Rocky Linux (version 8.4) was made available, marking a significant milestone for the community and the wider open-source world.
The project quickly gained traction, with a strong emphasis on transparency, community involvement, and support for enterprise workloads. The Rocky Linux Foundation was established to oversee the project and ensure its sustainability and growth.
