How to install AlmaLinux 8 on VirtualBox: CentOS Alternative

Learn the simple steps to install free RedHat-based AlmaLinux 8 Server GUI on VirtualBox Virtual Machine, PC, or Laptop along with its repository URL to get a CentOS alternative Linux distro. 

AlmaLinux from CloudLinux is the open-source replacement for the CentOS 8 which is not anymore a long-term supported OS version. Thus, to provide an alternative to CentOS 8, the AlmaLinux project has been launched by the CloudLinux developers, who are already known for their stable hosting operating system.

While writing this AlmaLinux installation article on VirtualBox, this Linux was still in the Beta stage, however, the steps will be the same for upcoming versions as well…

What we learn here:

  • Where to Download free RedHat-based AlmaLinux ISO file?
  • How to install AlmaLinux Minimal on VirtualBox virtual machine?
  • Step to set AlmaLinux 8 repository for Network Install ISO

Install and Setup AlmaLinux 8 on VirtualBox VM

Of course, you don’t want to start your main server on this relatively new Linux, although it is based on the popular RedHat code. Thus, creating a virtual machine would be the best idea to start to experience it before actually using it for some commercial purpose.

 

1. Download AlmaLinux 8 ISO

The first thing which we need to set up this CentOS 8 Linux alternative server OS is its DVD ISO file which is available on the Offical website. However, there will be two types of three files available for AlmaLinux one is Network Install CD; the second is Minimal (without extra packages) ISO, and the third one is the full DVD ISO with GNOME GUI desktop and other packages, this one is best for offline installation.  Thus, if you are planning to use AlmaLinux on Desktop for general purpose use then standard full ISO (with extra packages) will be a good option while the server users who want lightweight and selected package ISO can go for minimal or network version. Here is the link to download. Here we are downloading the Network CD ISO.

Type  Description Size
Network Install CD Need Internet to download packages ~ 650 MB
Minimal install Comes without any extra packages ~ 1.8 GB
Full DVD  With all packages and popular Desktop environments for offline installation ~ 8 GB

 

2. Minimum system requirements for AlmaLinux

  • 2 GB System RAM for GUI, however minimal ISO or CLI can go for 512 MB.
  • 2 GHz Processor or higher
  • 20 GB free hard Disk space
  • 64-bit x86 System

 

3. Create a Virtual Machine on VirtualBox

  • Run Virtualbox on Windows, Linux, or macOS
  • Click on the New Menu option to create VM
  • Give some name to your machine and then select Linux as OS type.
  • Set RAM for AlmaLinux, here we are using the GUI version thus use 2GB or more.
  • Create Virtual hard disk storage
  • Select Storage type VDI or VHD, if you are planning to use it later in VMware, then go for VMDK.
  • Dynamically allocated.
  • Set the storage space as per your requirement, however, 20GB will be an ideal one to start.

See the below screenshot to get an idea for the above-given steps.
