Download Rocky Linux 8 | How to Install Rocky Linux 8.4 on VMware workstation (CentOS 8 alternative)

Rocky Linux has been released on 21st June 2021 and If you have not explored it yet. I will show you how to install Rocky Linux 8.4 in your system.

Installing Rocky Linux in the VMware workstation provides you to explore it without worrying about the dual boot. You don’t need to install it in your system parallel to your existing operating system.

Instead, you can install it on the top of your host operating system using a VMware workstation player.

Why Rocky Linux

RedHat recently announced the shift in the strategy of CentOS and gave a shock to the open community. After December 31st 2021, CentOS will not be supported anymore. So Gregory Kurtzer, who was the founder of the CentOS project decided to work on Rocky Linux. It is a downstream build, like CentOS. Rocky Linux has been made from Scratch instead of a fork-like AlmaLinux. So it took some time to release and came after the AlmaLinux Launch.

System requirements to install Rocky Linux

Make sure you have these pre-requisites in place before installing Rocky Linux –

  • Vmware Workstation Player 15 or 16 (it’s free for personal use)
  • At least 1 Virtual CPU and 1 GB RAM.
  • At least 20GB of hard disk space
  • Backup your important files (optional)
  • Internet connection, as it requires to download some packages online during installation

In case, VMware workstation is not installed already. Select one of the below-mentioned buttons based on your Host OS for step by step installation instructions.

Download Rocky Linux 8.4 ISO 64-bit

  • Visit https://rockylinux.org/download/ and select your preferred ISO. I will go ahead with minimal. For a quick alternative, Click on Download button.

  • Alternatively, you can also select Torrent file, in case you have internet issues in your country like mine.
    • Just click on “Torrent” instead of minimal and save it. If you use chrome browser, it will get download automatically to your download directory.
Download Rocky Linux 8.4 using Torrent file
  • Open it with Torrent client like transmission (ubuntu) or BitTorrent (Windows 10) in your system
    • Download Rocky Linux DVD iso image of 9.91 GB. By default torrent file downloads complete DVD Iso as shown in image. You don’t have risk of losing or resuming your download, if you use torrent file.
Open Rocky Linux torrent file using Torrent client software transmission in Ubuntu
  • If you own Ubuntu 21.04 like me and you don’t have transmission installed by default. Run these commands one by one to install transmission in Ubuntu.
$ sudo apt update
$ sudo apt install transmission

You are good to open the Torrent file now and ready to download Rocky Linux 8.4.

Validate your ISO CheckSum for security

CheckSum validation is really an important step if you are downloading any software from the internet. To make sure it’s legitimate.

  • Open Terminal in Ubuntu by pressing <Ctrl + Alt + T>. Go to your download directory and run this command.
$ cd ~/Downloads
$ sha256sum Rocky-8.4-x86_64-minimal.iso

You will get a long key as shown in the image.

Validate checksum using Sha256 command in Ubuntu Linux

Just match it with the checksum key provided on the Rocky Linux website or download it from here.

If you use Windows 10, Just open the command prompt (CMD) and type the following command to validate the checksum. Either change your directory to Rocky Linux image directory or give a path to the Rocky Linux iso file.

For example, I am in the software directory, where I have my Rocky Linux image iso. So I don’t have to give a path, only the file name is enough as shown in the image.

Run Certutil command to get the SHA256 key.

C:\ certutil -hashfile "path to Rocky Linux iso file" SHA256
Validate Rocky Linux iso image checksum in Windows 10 using certutil command

Check out the video tutorial in this post, in case any issue matching the Checksum file.

How to install Rocky Linux in VMware Workstation Player 16

These are the two phases of Rocky Linux installation –

  1. Create a virtual machine for Rocky Linux
  2. Install Rocky Linux into the Virtual machine

Just follow along step by step to install Rocky Linux in the VMware workstation player.

Step1 – First Launch VMware workstation player 16

The first step would be to create a virtual machine for Rocky Linux 8 in Vmware Workstation 16. So, open the VMware workstation player in your host operating system. For example, I am using Windows 10 as a host OS.

  • Look for VMware workstation in Windows search bar and click Open as shown in image.
Open-vmware-workstation-16

Step2 – Start “Create a New virtual machine” Wizard

Click on Create a new virtual machine, it will start a new Rocky Linux VM wizard.

Step3 – Select media option “I will Install operating system later

On the Media selection page, you have three options.

  1. Installer Disc – if your laptop or PC has CD/DVD drive and you love to burn iso images to CD’s and Dvd’s (old school method). You can select this option. Your physical drive will be visible as /dev/sr0 and you just need to insert the installer disc, you prepared and click on Next.
  2. Installer disc image file (iso) – using this option, you can just browse for your downloaded ISO on your laptop or PC. we will do it in second phase by different route in this tutorial.
  3. I will install the operating system later – if you are not willing to install Operating system immediately or you are not ready with Rocky Linux iso CD or image, you can select this option. If you will continue using this option, it will create a new Virtual machine for you.

I will choose the “install the operating system later” option to showcase each and every step involved to install Rocky Linux in VMware Player -> Click Next.

Step4 – Select a Guest operating system

Select “Guest operating system” as Linux and Version as “Centos 8 64-bit” in wizard-> Click Next.

Note:- Rocky Linux not listed in dropdown currently. But it’s the replacement of CentOS 8. So you can select CentOS 8 64-bit as the version.

Step6 – Specify Disk capacity for Rocky Linux VM

Now it’s time to define your virtual disk size. Generally, 20GB is enough for Rocky Linux or even any other Linux installation. We will also go with the default 20GB disk size.

  • Choose the “split virtual disk into multiple files” option-> Click Next.

specify-disk-capacity-for Rocky Linux 8 VM

A quick explanation of options –

  • Store virtual disk as a single file – You can select this option, but I won’t recommend this. In case you want to copy or move this VM to other PC or laptop, Managing a single file of 20GB or more would be difficult.
  • Split virtual disk into multiple files –  Management of Virtual machine disk file is easy but may have some performance impact due to large files.

Step7 – Review and Customize hardware, if required

On the next screen, click on “Customize hardware” and increase RAM size from 1024 MB to 2048 MB, If you have enough memory in your PC. Otherwise, you can leave it 1024 MB only.
