The objective of this guide is to show how to set the system time zone on AlmaLinux. This can be done from both GUI and command line, so we'll be covering both methods in the following instructions.
Setting your system time and time zone is usually done when initially installing AlmaLinux or migrating from CentOS to AlmaLinux. If you skipped that step during installation, have switched time zones, or your system clock has drifted out of sync, we'll help you get it fixed.
In this tutorial you will learn:
How to set time zone on AlmaLinux from GNOME GUI
How to set time zone on AlmaLinux from command line

Docker is a tool that is used to run software in a container. It's a great way for developers and users to worry less about compatibility with an operating system and dependencies because the contained software should run identically on any system.
If you've recently installed AlmaLinux or migrated from CentOS to AlmaLinux, you may be wondering how to get Docker up and running on the system. Unfortunately, Red Hat Enterprise Linux doesn't offer native support for Docker, and neither does AlmaLinux, since it is a fork of RHEL. Instead, Red Hat pushes support for Podman, an alternative to Docker. This makes Docker a bit harder to install, but it's still possible on AlmaLinux.
In this guide, we'll show you how to install Docker on AlmaLinux and get started with installing containerized software. After Docker is installed, you can use it to install software packages much the same way you would use your distro's package manager to download an app. The difference of using Docker is that everything is more automated, with compatibility and dependencies no longer being potential issues.
Up until a late 2020 announcement from Red Hat, CentOS Linux had a longstanding reputation as a dependable and enterprise-class Linux distribution. And now, the main purpose of CentOS is shifting. Along with that comes a name change to CentOS Stream.
In this article, we'll talk about this change of direction for CentOS, and what it means for the huge community of users and businesses that have relied on the distro for years. We'll also see what's next, as many users are left scrambling for a replacement so they can avoid switching to CentOS Stream.
In this guide, we'll show you the step by step instructions to add a new user on an AlmaLinux system. This can be done through both GUI and command line. We'll be covering both methods in this guide, so you can pick whichever option is most convenient for you.
In this tutorial you will learn:
How to add a new user on AlmaLinux from command line
The hostname of a Linux system is important because it's used to identify the device on a network. The hostname is also shown in other prominent places, such as in the terminal prompt. This gives you a constant reminder of which system you're working with. It's a real life saver when you're managing multiple systems through SSH and those command line terminals start to blend together in your mind.
Of course, IP addresses are used when devices need to communicate with each other, but those can change frequently. Hostnames give us a way to know which device we're interacting with either on the network or physically, without remembering a bunch of numbers that are subject to change. Thus, it's important that your system bears a hostname which helps you to identify it quickly. For example, "backup-server" is much more informative than "server2." If you can't easily identify a system's purpose from the hostname, it's time to change it.
In this guide, we'll show you how to change the hostname on AlmaLinux. This can be especially useful if you've recently migrated from CentOS to AlmaLinux and need to update the hostname accordingly. Changing the hostname can be done either by command line or GUI, and we'll show you the steps for both methods below.
In this tutorial you will learn:
How to change the AlmaLinux hostname from command line

The release of AlmaLinux in 2021 was spurred by the change of CentOS Linux from an enterprise-stable operating system to an upstream development branch of RHEL.
With AlmaLinux being branded as a replacement for CentOS, and giving users the option to migrate to AlmaLinux from CentOS, you may be wondering what the differences are between these operating systems.
In this guide, we'll look at what makes AlmaLinux and CentOS so similar, and why new differences between the distributions are causing many to distro hop.
The objective of this guide is to show how to check what version of AlmaLinux a system is running. Whether you've migrated from CentOS to AlmaLinux or performed a fresh install, it's important to keep tabs on the state of your system. This includes information such as the version number of the operating system, kernel version, and other release information.
AlmaLinux is a fork of Red Hat Enterprise Linux, which releases a new major version every few years. Finding your system's version will inform you whether or not you've fallen behind on the latest updates. It's always recommended to update AlmaLinux for the latest security patches and features.
In this tutorial you will learn:

These days, most systems are configured to connect to a network automatically through DHCP by obtaining an IP address assigned through your ISP or your home router. But there may come a time when you wish to opt for a static IP address and you will want to change it. It may be that you are configuring a home LAN and you don't want to use DHCP or simply want a static IP address that you can access from outside your home.
Restarting the network of your AlmaLinux system can be a useful troubleshooting step, for example if you're having problems connecting to the internet.
When it comes to IP addresses on AlmaLinux, you have two main options for how you configure your network interfaces. You can either obtain an IP address automatically with DHCP, or configure the system to use a static IP address, which never changes.
In this guide, we'll show how to configure a static IP address on AlmaLinux. This can be done either through GUI or command line, and we'll be going over both methods. Once a static IP address is configured, it won't change again unless you manually change the IP address later, or turn DHCP on. You can follow this guide whether you've migrated from CentOS to AlmaLinux or have performed a normal AlmaLinux installation.
DID YOU KNOW? You can also configure your DHCP server (or router) to assign your AlmaLinux system a static IP address. This means that your system would still use DHCP, but the server or router will reserve the same IP for the MAC address of your computer's network interface. Instructions for this will vary, depending on your network environment and DHCP server.
In this tutorial you will learn:
How to configure a static IP address via GNOME GUI
How to set a static IP address by directly editing an interface file
How to set a static IP address using the nmcli utility
Like all Linux distros, it's important to keep your AlmaLinux system up to date in order to make sure that you have the latest security updates and newest features. Updating the system usually involves simply upgrading all installed packages to their latest versions.
Since AlmaLinux is a fork of Red Hat Enterprise Linux, there are also system upgrades to a new version every few years, coinciding with the new RHEL releases. This type of update is a full system upgrade, and it's different than simply keeping AlmaLinux up to date.
In this article, we'll cover updating a AlmaLinux system on a per package basis and upgrading the entire operating system. This can be done via command line and GUI. Both methods will be shown in this guide, so you can pick whichever is easier for you.
This is thanks to DHCP, a protocol that the system uses to lease a local IP address from your router. However, some RHEL based distros, including AlmaLinux, don't have this feature enabled out of the box.
In this guide, we'll show you the step by step instructions for a couple different methods of connecting to a network automatically in AlmaLinux. Specifically, this will enable DHCP on a network interface, either temporarily or persistently.
In this tutorial you will learn:
How to connect to network via DHCP temporarily
How to configure persistent DHCP network configuration via command line and GUI

AlmaLinux is an enterprise-ready Linux distribution forked from Red Hat Enterprise Linux. It's a very stable operating system that's meant especially for production envrionments (servers), but you can also install a GUI on AlmaLinux and use it as a desktop operating system.
In this guide, we'll be going through the step by step instructions of installing AlmaLinux. You can follow along with our steps whether you're installing AlmaLinux on a desktop or server. If you already have CentOS installed and want to switch to AlmaLinux, please see our guide on migrating from CentOS to AlmaLinux.
With the change of CentOS Linux from an enterprise-stable operating system to an upstream development branch of RHEL, new projects have rushed to fill the gap left in its wake.
The distros you've probably already heard of are AlmaLinux and Rocky Linux, the two top contenders to act as a viable replacement for CentOS.
For the CentOS users that have decided to switch to another RHEL fork, rather than distro hop entirely, they'll face the question of, "Which distro should I use? AlmaLinux or Rocky?"
In this guide, we'll compare AlmaLinux and Rocky Linux across a few key areas. We'll weigh their pros and cons, see how they stack up against each other, and ultimately give you enough information to help you decide which one you should use.
The main motivation behind the creation of AlmaLinux was to be a viable replacement for CentOS Linux at the time of its shift from an enterprise-stable operating system to an upstream development branch of RHEL.
Now that AlmaLinux is released, it still leaves CentOS users wondering how to switch operating systems. Ideally, this should be done as seamlessly as possible, to prevent downtime, loss of data, etc. In this guide, we'll show you the step by step instructions to migrate from CentOS to AlmaLinux with just a few commands.
