After RedHat announce that it will discontinue CentOS, CloundLinux which maintains its own commercial distribution created AlmaLinux. Its first stable version ”AlmaLinux OS 8.6″ was released on 30th march 2021.

In this guide, I will discuss the steps that you can follow to install AlmaLinux “Emerald Puma” on your system.

Prerequisites

To follow this guide you should have the following –

A computer with at least 2 GB RAM, 20 GB hard disk, and a 64-bit processor
A 16 GB pen drive to use as an installation medium
Good internet connection for downloading AlmaLinux ISO file

Download AlmaLinux ISO file

For installing AlmaLinux you need its image file, to download the AlmaLinux iso file first go to the download page on its official website then choose a version for x86_64 architecture.

You can download one of the given setups of AlmaLinux –

Minimal – This is the minimal setup of AlmaLinux of size 1.4 GB
DVD – The DVD iso is around 7.5 GB in size
Boot – This is the network installer setup of around 700 MB
Torrent – If you want you can download the operating system by using a torrent client

You can directly download AlmaLinux-9.0-x86_64-dvd.iso by using the given command –

wget http://repo.extreme-ix.org/alma/9.0/isos/x86_64/AlmaLinux-9.0-x86_64-dvd.iso

Make USB bootable

Once the download is completed and you have the AlmaLinux ISO file, now you need to make the USB bootable. You could use one of the given methods on your system to make your Pendrive bootable –

On Windows machine

If you are using a Windows system the best-recommended way to create a USB bootable is by downloading and using the Rufus application. This tool has a user-friendly GUI where you can easily select your iso file and use it to make the USB bootable.

On a Linux system

If you are using a Linux system then you could use the dd command. To make USB bootable using this method first open your terminal by pressing ctrl+alt+t and then use –

sudo dd if=AlmaLinux-9.0-x86_64-dvd.iso of=/dev/sdb status=progress

Where AlmaLinux-9.0-x86_64-dvd.iso is the input file and /dev/sdb is the name of USB don’t forget to replace it with yours.

I will recommend using automatic partitioning until you don’t know about the manual partitioning of a disk. After selecting the options click on Done.

The next option in this column is KDUMP, keep it to its default.

Click on the Network & Host Name to configure the internet on your system. Here you can enable an existing network or add a new one. Once configured click on Done.

Next in the Localization column, click on Keyboard to configure the keyboard layout, and Language Support to choose your language. Click on Time & Date to choose your time zone.

Below the LOCALISATION column, you will see USER SETTINGS, click on Root Password to set a password and enable the root account. If you enter a weak password you need to click twice on Done.

If you want to create a new user then click on the User Creation this will open the window to fill in the details of the new user as given in the image below.
