Built by CloudLinux to address the void left by CentOS 8, AlmaLinux emerges as a much-needed alternative for production environments after RedHat shifted the direction of the CentOS project.
You're likely familiar with RedHat's controversial decision to transition the CentOS project into CentOS Stream, which serves as a developer-focused, upstream version of RHEL. This move sparked concern among many CentOS users, but the introduction of AlmaLinux has helped ease those worries.

AlmaLinux is a free and open-source operating system that offers exact 1:1 binary compatibility, making it a direct clone of RHEL 8.0. It is built to succeed CentOS 8 and can be deployed across various setups such as virtual machines, physical servers, desktops, and enterprise systems.
The first stable release of AlmaLinux, known as AlmaLinux 8.3, became available on March 30, 2021. The current stable version – and second major release – is AlmaLinux 8.5.
AlmaLinux 8.5 is a fully production-ready OS and serves as a direct replacement for the upcoming end-of-life CentOS 8 series. Based on Red Hat Enterprise Linux (RHEL) 8.5, this version was released on November 21, 2021—just seven days after the launch of RHEL 8.5.
Major Features of AlmaLinux 8.5
- Secure Boot: In AlmaLinux 8.5, secure boot is completely supported, allowing smooth installation with secure boot enabled. This feature is especially important in enterprise settings where security is paramount.
- OpenSCAP security profiles: This release now supports OpenSCAP security profiles, a set of tools used to identify configuration issues and vulnerabilities within a system.
- The devel-repository now includes additional packages and dependencies. However, keep in mind: these are specifically for development use and shouldn't be activated in live environments.
- New module streams introduced include Python 3.9, Redis 6, MariaDB 10.5, and PostgreSQL 13.
- Updated compiler toolsets now include GCC Toolset 11, LLVM Toolset 12, Go Toolset 1.16, and Rust Toolset 1.54.

Download AlmaLinux DVD ISO images
You can grab the AlmaLinux 8.5 ISO from the official download site. Choose between using a Torrent or downloading the full DVD ISO image, which is quite large at 9.1GB. There are more than 100 mirror locations worldwide, so you can select one nearest to your region for faster downloads.
The DVD ISO contains a GUI and all essential software packages needed to get started. Also, note that the default desktop environment for AlmaLinux is GNOME 3.38. If you have a slow internet connection, consider downloading the minimal ISO instead, which is around 2GB.
It's also worth mentioning that AlmaLinux provides a migration script for existing CentOS Linux users, enabling them to switch without having to do a fresh install. As always, ensure you back up your data before migrating to avoid potential issues.
