Individuals and organizations that require an enterprise-grade linux distribution, without the need for a commercial license agreement. AlmaLinux OS is also a perfect replacement for anyone who has historically relied on the CentOS Linux releases to achieve computing objectives, and for whom CentOS Stream is not the right solution.

In July of 2023, we announced that we were shifting our goal from being a downstream rebuild of RHEL to maintaining ABI compatibility with RHEL. For the AlmaLinux team that means that everything from software applications to kernel modules that work on RHEL will work on AlmaLinux, and if they don't we would consider that a bug.

AlmaLinux OS 9.2 is FIPS-140 compliant. Read more in this blog post: FIPS Validation for AlmaLinux OS


The initial backers and supporters for AlmaLinux OS were already extremely active in the enterprise Linux ecosystem, and had significant experience with RHEL forks. They knew the impact that the loss of CentOS Linux would have across all industries, and had the means and knowledge to help.

The AlmaLinux OS Foundation is a 501(c)(6) that was founded in March of 2021 to own and manage the AlmaLinux OS project. We have been involving the community since the beginning, and the governing board is chosen by members of the foundation. At all times, AlmaLinux OS will be free and open.

Switching Linux distros can be a headache, but that is not the case when switching from CentOS to AlmaLinux OS. Using AlmaLinux-deploy you can migrate to AlmaLinux in-place. If you are coming from CentOS 7, or need to upgrade between major versions, EL易升 (developed and maintained by the AlmaLinux Community) allows you to migrate to, and upgrade AlmaLinux in-place.

Since AlmaLinux is binary compatible with RHEL®, your applications and services should be completely interoperable. You can rapidly migrate any number of servers using AlmaLinux-deploy. 如果你使用的是 CentOS 7 或 8,并且需要有关升级和迁移的帮助,请检阅 ELevate.

The AlmaLinux OS Foundation has committed to supporting AlmaLinux OS 8.x until 2029, and AlmaLinux 9.x until 2032. This includes stable and thoroughly tested updates and security patches.

One of the most significant features of AlmaLinux is its binary compatibility with Red Hat Enterprise Linux (RHEL). This compatibility ensures that software developed and tested on RHEL can be easily deployed on AlmaLinux without modifications, making it an attractive choice for businesses seeking a seamless migration path.
Despite Red Hat’s actions, it appears at least one of the RHEL clones is thriving and showing how open source can deal with similar threats.
Joe Brockmeier, an open-source community expert, and former Red Hatter, appreciates what AlmaLinux is doing. 'The AlmaLinux community has chosen to be the friendly fork.'
AlmaLinux announced that the distro’s latest and greatest, AlmaLinux 9.2, now has FIPS 140-3 certification, which means it has passed the Federal Information Processing Standard’s latest benchmark for validating the effectiveness of cryptographic hardware.
AlmaLinux was one of the first such alternatives, and it has quickly risen to the top of the heap.
AlmaLinux very quickly became the CentOS replacement to beat. 48 hours after Red Hat released version 8.5 of Red Hat Enterprise Linux (RHEL), the developers released version 8.5 of AlmaLinux.
