AlmaLinux is a Linux-based operating system designed for server needs. It emerged as an alternative following a policy change to CentOS. Many server users needed a stable, free, and compatible system with Red Hat Enterprise Linux. AlmaLinux was created to address this need.

AlmaLinux is developed by the community and supported by a nonprofit organization. Its primary focus is long-term stability and full compatibility with RHEL.

A Brief History of AlmaLinux

In 2020, CentOS changed direction to CentOS Stream. This change left many users without a stable system for production.

In response, CloudLinux initiated the AlmaLinux project. The goal was clear: to create a free operating system that was 1:1 compatible with RHEL.

The first version of AlmaLinux was released in 2021. Since then, the community has grown rapidly.
