Welcome to AlmaLinux OS, a 1:1 binary compatible RHEL fork, a free Linux OS for the community, by the community.
Why “Alma”? Community is the soul of Linux – and in honor of the community, we decided to call our new distribution Alma: a Latin-language word for soul.
AlmaLinux OS 8.4 (based on RHEL 8.4) is now available. The first stable release of AlmaLinux OS was introduced on March 30, 2021. You can watch our Live Launch Event to learn more.
AlmaLinux OS is an open-source, community-driven project that intends provide and alternative to the CentOS Stable release. AlmaLinux is an OS that is 1:1 binary compatible with RHEL® 8 and a global collaborative of the developer community, industry, academia and research which build upon this technology to empower humanity.
The AlmaLinux OS Foundation is a 501(c)(6) non-profit created for the benefit of the AlmaLinux OS community. The foundation is funded by a $1M annual sponsorship from CloudLinux, Inc. as well as additional funding and support from ARM Holdings, Amazon Web Services, cPanel, Equinix, HiVelocity, Mattermost, The Oregon State University Open Source Lab, Plesk, Progress and others.

Who is AlmaLinux OS for?
Anyone who currently relies on the CentOS stable release to achieve computing objectives. Individuals and organizations that require an enterprise-grade, RHEL-like distribution but who do not want to or cannot pay for a RHEL license.
Why did we call it AlmaLinux OS?
Alma means soul in Spanish and other Latin languages. Looking back, it is easy to see that Linux is as popular and pervasive as it is thanks to the efforts of a passionate, diverse developer community. This community is the soul of Linux, and everyone that relies on a Linux distribution is indebted to the efforts of the Linux community. That is why we called our new distribution AlmaLinux OS.
What motivated us?
We’ve been doing it--for 10 years. We have the staff, the experience, the capabilities and the resources.
How is the community protected from future course changes?
The project is owned and controlled by a non-profit and the Community is involved in every step, including in the governing board. Since everything is open, the community can decide to make any changes they with to make to the project at any time.
Why should I rely on a team with members from CloudLinux, Inc. for a CentOS alternative?
You're not. There is a community of people behind the project and CloudLinux is just one of them. CloudLinux's core product, the CloudLinux OS, is a RHEL fork that has been in place for over ten years. More than 4,000 companies including Dell, Liquid Web, and 1&1 rely on the CloudLinux OS across more than 200,000 product installations. CloudLinux has proven experience in creating and maintaining a RHEL fork and have done so starting with RHEL release 5, right through to release 8. AlmaLinux OS is an opportunity for us to channel our expertise in RHEL into a Linux distribution that serves the broader community. Furthermore, we are including the Linux community right from the inception of AlmaLinux OS. Moving forward, community members will be on the governing board for the AlmaLinux OS project and involved in key decisions too. Finally, AlmaLinux OS will always be free and open source. The community can pick up and continue to develop AlmaLinux OS at any time.
When do we plan on releasing AlmaLinux OS?
In delivering AlmaLinux OS we are essentially continuing a process that is already in place due to our experience in forking RHEL. We are confident that we can rapidly deliver AlmaLinux OS, and plan on doing so in Q1, 2021.
I want to convert from CentOS to AlmaLinux OS. How do I do it?
Switching Linux distros can be a headache, but that is not the case when switching from CentOS to AlmaLinux OS. Just like CentOS, AlmaLinux OS is a 1:1 binary compatible fork of RHEL, so switching is simple. We will provide instructions to swap repositories and keys once the Beta is out.
Can I really port an entire fleet of servers from CentOS to AlmaLinux OS with a single command?
As stated, AlmaLinux OS will be a 1:1 binary compatible fork of RHEL, which means that your applications and services will remain compatible. For that reason, you can rapidly migrate any number of servers with just one command.
Until when will we support AlmaLinux OS?
AlmaLinux partners has committed to supporting AlmaLinux OS until 2029, including stable and thoroughly tested updates and security patches.
