AlmaLinux: A Comprehensive Overview
Introduction
AlmaLinux is an open-source, community-driven Linux distribution that emerged as a prominent alternative to CentOS. It aims to provide a 1:1 binary compatible fork of Red Hat Enterprise Linux (RHEL), ensuring that users have a free and stable platform for their server and cloud environments.
History
The inception of AlmaLinux can be traced back to December 2020, following the announcement of CentOS’s shift from a stable release to a rolling-release model. This shift concerned many users who relied on CentOS for production environments. In response, the CloudLinux team announced the creation of AlmaLinux, which would be a free and open-source alternative that would maintain compatibility with RHEL.
The first stable release, AlmaLinux 8.3, was launched in March 2021, and since then, AlmaLinux has experienced rapid adoption in various sectors. The AlmaLinux OS Foundation was also established to ensure the sustainability and community-driven nature of the project.
