What is AlmaLinux? A Quick Introduction

AlmaLinux is a free, open-source, community-driven Linux distribution that’s binary-compatible with Red Hat Enterprise Linux (RHEL). It was developed by the AlmaLinux OS Foundation, a 501(c)(6) non-profit organization, to provide a stable, secure, and production-grade enterprise operating system. AlmaLinux was originally called Project Lenix but was renamed in January 2021. 

AlmaLinux History: How it Developed?

Back in 2020, the CentOS world got shaken up when it announced a shift away from being a stable, RHEL (Red Hat Enterprise Linux) compatible option. This left many users who relied on CentOS’s stability in a bit of a bind.

Enter AlmaLinux, a brand-new project that emerged in early 2021. The name itself is a cool twist, with “alma” meaning “soul” in many Latin languages. The idea? To capture the essence of the passionate Linux community and create a free, stable alternative that carried the torch of the traditional CentOS experience.

Developed by the AlmaLinux OS Foundation, AlmaLinux hit the ground running with a beta version in February 2021. By March 2021, the first stable release was out, offering a whopping eight years of support. This commitment to long-term stability was music to the ears of users who craved a reliable foundation for their projects.

Big companies like ARM, Amazon Web Services, Equinix, and even Microsoft saw the potential in AlmaLinux and adapted this operating system.  It’s safe to say that AlmaLinux has become a major player in the enterprise Linux game, all thanks to its focus on community, stability and all-important RHEL compatibility.  So, if you’re looking for a dependable, community-driven Linux option, AlmaLinux is definitely worth checking out!

What are the Editions of AlmaLinux?

Like every other release, AlmaLinux also has different versions. In this section, you will explore multiple AlmaLinux versions, including the latest ones. As you can see, this OS is not like Windows, which carries a legacy of versions. Only 3 years ago, AlmaLinux 8 was launched, and now AlmaLinux 9 is also used by the industries. Let’s decode them one by one, and we will find the best between AlmaLinux 8 vs AlmaLinux 9.

What Was The Purpose Of Designing AlmaLinux?

In the IT industry, there is a plethora of Linux operating systems available. Then why AlmaLinux outpaced the competition? What was the motto behind it? Let’s have a quick look. 

So, the answer is that AlmaLinux is considered to be one of the best enterprise-grade operating systems that can be installed in cloud hosting servers and bare metal servers. Hence, meeting business growth is not a challenge any more! AlmaLinux has also emerged as an RHEL alternative where users build, secure, and manage application-centric operating architecture. 

AlmaLinux is compatible with different environments, which include physical and desktop environments. And because of its reliability, many Linux VPS hosting servers preconfigure them for customers. Both personal and enterprise needs can be met through this operating system. However, for personal purposes, you need a strong budget!

AlmaLinux Features: Decoding Their Best USPs

Are you satisfied with the justification behind the AlmaLinux foundation? If yes, let’s brainstorm some of the key AlmaLinux features that make it a powerful Linux distro.

AlmaLinux Features: Decoding Their Best USPs

1. CentOS alternative

Do you want a CentOS alternative? AlmaLinux has the solution for you! With this, you don’t want to be especially dependent on CentOS 7 or its other versions. AlmaLinux has the potential to create the same positive user experience in terms of design and performance. It follows the latest UI/UX trends because of the binary compatibility with RHEL. So, if you are a CentOS user, don’t hesitate to use AlmaLinux; it will give the same user experience to you. In fact, you can migrate the same script from CentOS to the AlmaLinux environment. 

2. Stability and Source Coding Standards

All source code of AlmaLinux is based on RHEL. So, if you are familiar with RHEL or basic Linux commands or codes, AlmaLinux is a cakewalk for you! Later, you can optimize these codes as per your requirements. All source codes are publicly available, and that’s the magic of its community!

So, here’s the deal with AlmaLinux and the new software. Imagine CentOS Stream as a kind of testing ground. New stuff gets rolled out there first, like a trial run. Once they iron out any kinks and squash the bugs, Red Hat Enterprise Linux, the commercial version, gets the update. Then, finally, it trickles down to AlmaLinux users. AlmaLinux might not be on the cutting edge, but you get a stable system that’s been tested.

3. Fees and Licenses

It’s free! Yes, you heard it right! This statement is justified on the AlmaLinux OS. Despite being used commercially, this Linux distro meets the online business goals, providing users with a set of features and paid operating systems for free. 

Hence, there is no contract fee or registration charge involved. You can use AlmaLinux without restrictions. Instead of its paid competitors, this open-source operating system caters to your needs. 

4. Community and Support

No more technical burden to access the AlmaLinux. After all, you are getting support from different AlmaLinux communities in terms of project financing and development. Several IT community members tap the potential of this Linux community to build a strong open-source foundation. 

If you want more support, managed web hosting service providers are available to help you out! There are professional certified experts who assist in operations and other technical activities.

How to Install AlmaLinux? A Step-by-Step Guide

Installing AlmaLinux is a straightforward process, but it involves a few steps. Here’s a rundown to get you started:

How to Install AlmaLinux
  • Download the AlmaLinux ISO: Head over to the official AlmaLinux website https://almalinux.org/get-almalinux/ and grab the ISO image that suits your system’s architecture (64-bit is recommended for most users).
  • Create a Bootable USB Drive: You’ll need a USB drive with at least 2GB of free space. Use a tool like Rufus or Ventoy (depending on your operating system) to write the downloaded ISO image onto the USB drive. This creates a bootable USB that you can use to install AlmaLinux.
  • Boot from the USB Drive:  Restart your computer and configure your BIOS/UEFI settings to boot from the USB drive first. This usually involves pressing a specific key (like F12 or Delete) during startup to access the boot menu and selecting the USB drive.
  • Follow the Installation Steps:  Once you boot from the USB drive, the AlmaLinux installer will appear. The installer will guide you step-by-step throughout the installation process. Here are some key things you’ll configure:
  • Language and Keyboard Layout: Choose your preferred language and keyboard layout.
  • Storage: Decide how you want to partition your disk drive. You can choose automatic partitioning for a simpler setup or manual partitioning for more control.
  • Network Connection: If you’re connected to the internet, you can choose to configure your network settings during installation.
  • Root Password and User Account: Set or reset with the strong password for the root user (the main administrative account) and create a regular user account for everyday tasks.
  • Begin Installation:  Once you’ve reviewed your configuration choices, initiate the installation process. The installer will format your drive (if necessary) and copy the AlmaLinux files to your system.
  • Reboot and Log In:  After the installation is complete, you’ll be prompted to reboot your system. Remove the USB drive and boot normally. You’ll then be able to log in to your newly installed AlmaLinux system using the user account you created during installation.

AlmaLinux Alternatives: Rocky Linux Vs CentOS vs RHEL

If you are not satisfied with the AlmaLinux, here are some of the AlmaLinux alternatives which you can consider. Below, we have discussed about AlmaLinux vs Rocky Linux vs CentOS vs RHEL. But before that, let’s decode them in depth. 

AlmaLinux Alternatives: Rocky Linux Vs CentOS vs RHEL

1. Rocky Linux

Rocky Linux is another solid option, built from the same RHEL source code as AlmaLinux, so you know it’s reliable. Think of it as the “stick to the plan” sibling.

Rocky Linux is all about stability, which is great for folks who need their systems running smoothly all the time. It works on a bunch of different system setups, no problem. The downside? Updates might not be the snappiest, and some folks say it’s not the most user-friendly.

It’s completely free, has a whopping 10-year support window, and even throws in a handy migration script to help you switch over from other Enterprise Linux distributions.

2. CentOS

CentOS was the go-to for many years, built from RHEL source code and offering a free, community-driven alternative. CentOS recently decided to wind things down. So, while it’s still technically out there for older versions, it won’t be getting new updates or support. 


RHEL, the king of the stable Linux castle! This is the premium option, the source code that AlmaLinux and Rocky Linux are based on. It’s known for rock-solid stability and top-notch enterprise support, but there’s a price tag attached. Think of it as the designer jeans with all the bells and whistles – fantastic quality, but you’ve got to pay for the name.

The upside? RHEL is insanely stable, perfect for mission-critical systems that can’t afford any downtime. You also get access to professional support, which can be a lifesaver if things get complicated. But yeah, it’s not free. So, it’s all about weighing the pros and cons – you might be willing to shell out for the extra security and support, or you might be happy with a free, community-driven option like Rocky or Alma.
