How to Install and Set Up Red Hat Enterprise Linux (RHEL)

Red Hat Enterprise Linux installation differs slightly from installation of other distributions. How to install and configure RHEL on your computer is described here. Red Hat Enterprise Linux, or RHEL, is more than just a server or operating system. Instead, it is an ecosystem that was created for and around businesses. Conglomerates, crucial infrastructures like banks and government agencies, and other entities place their trust in the Red Hat system.

Even though it may only be enterprise-grade software, one can still sample it without being a member of a firm. Red Hat Enterprise Linux is available for free download with a risk-free trial right now!
This manual will show you how to download and set up Red Hat Enterprise Linux.

Step 1: Grab the RHEL ISO!

You need the operating system’s disc image to install a new operating system, whether it be on a physical machine or a virtual one (ISO). Important setup and system files required for a successful installation are contained in the ISO file.

Make sure your USB or DVD has enough free space to fit the setup files because the RHEL ISO file size is around 10GB. If not, utilising the terminal is a simple way to make room.
To get the most recent RHEL ISO, you must first create an account. Click on Register and provide the required information on the website. A confirmation email might be required for account activation. complete the procedure to unlock the ISO download.

Step 2: Prepare the Virtual Machine

Instead of setting up a virtual machine, individuals who will be installing Red Hat bare-metal on their PCs must make a bootable USB. If you intend to install RHEL directly on your PC, you can skip this step.

If you have experience configuring virtual machines, this should be a piece of cake for you, so you may move on to the next stage without waiting. Continue reading if you’re unfamiliar with this procedure. We’ll presume you’ve previously downloaded and set up VirtualBox. If not, this installation tutorial for VirtualBox can assist.

Open VirtualBox and select New. Choose Linux and Red Hat (64-bit) as the version under machine type. Set aside at least 3096 MB of RAM. You have the option to keep the current settings or increase the hard disc size. But don’t reduce the size.

Click Create after the system configurations are complete. Your freshly generated virtual machine ought to appear on the left panel at this point.
After completing the necessary preparations, it’s time to provide the virtual machine an ISO to read setup files from.

Go to the virtual machine’s settings and select the Storage tab. Select the RHEL ISO file you had previously downloaded by clicking on the disk-like icon under Controller: IDE.

Step 3: RHEL installation

To launch your newly formed VM if you are installing RHEL on a virtual computer, click Start. If you’ve made a bootable USB drive, plug it in so you can start your computer from it instead.

Use the arrow keys to navigate to Install Red Hat Enterprise Linux System on the GRUB bootloader screen, then press Enter.

You should see a screen where you can choose your favourite language and location. When you confirm your choice, a second popup will appear warning you that the build version is not suitable for a production environment and requesting that you confirm the installation or roll back the modifications.

A word of advice: You should reconsider installing RHEL bare metal if you are considering doing so. If you’re really committed, we advise purchasing a paid, deployable build of RHEL. This version is free, thus it’s an experimental build that might be prone to problems and crashes.

You can click on I wish to proceed without risk if you’re using a virtual machine. You should then be directed to the RHEL installation dashboard, from which you may partition the disc, create user profiles, and make a variety of other crucial adjustments.
Choose the virtual drive that you had previously designated for installing RHEL, then click Done.

Make a user profile next so you can log in to Red Hat following installation. The procedure is identical to that of every other Linux installation. You should be able to instal any Linux distribution if you have prior experience doing so.

To finish, create a special, lengthy root password for the admin account. Once all of the pre-installation tasks have been completed, click Begin Installation to begin installing Red Hat Enterprise Linux on your computer.

Grab a cup of coffee because, depending on your computer’s capabilities or the resources you gave the virtual machine, it could take up to a few minutes.

Press the Reboot button when the installation is complete to restart your computer and launch a brand-new RHEL installation. You might be asked to accept the licensing terms when you log in for the first time.

Go over the terms and conditions in detail. If the document is satisfactory to you, select I agree to the license agreement and then select Finish Configuration. It will immediately launch you into RHEL’s GNOME Display Manager (GDM), which is the login screen by the way.

Red Hat Enterprise Linux is now operating on your desktop once you log in with the credentials you created during installation.

Don’t forget to eject the ISO file if you installed it using VirtualBox; otherwise, there can be a problem when the computer boots up. The RHEL installation procedure is now complete. It is rather simple, but less user-friendly and streamlined than Calamares-based distros.

Step 4: Post Installation Wrap Up

It is only normal to feel eager to play around with the distro, test out commands, and other things now that the installation procedure is complete. You do need to complete a significant post-installation job, though. Otherwise, you won’t be able to modify the system in any way, including installing something as simple as Neofetch.

RHEL, as we already mentioned, is a subscription-based operating system. To receive even basic services, you must obtain your free licence.

Open a terminal and register yourself using the subscription manager to activate your free subscription.

subscription-manager register –username yourusername –password yourpassword

Attach the subscription manager after that.

attachment-manager subscription —auto

If everything went according to plan, you should now be able to run commands, instal packages, and update your system—which is the next thing you need to do.

Update your Red Hat system as soon as you can after it has been registered and enabled. The fact that this is an unfinished, beta build means that developers will be experimenting a lot.

Therefore, every update has the potential to either damage or improve your system. It’s still recommended practise to keep your system updated even though you won’t be able to know which update does what.

Keeping Your RHEL Server Secure

Even though your RHEL system is operational, it still lacks practical security. It would be better to make the effort to fortify it if you were planning to use it as a server.

There are several open-source and free security solutions available that can protect and safely manage your system. A select handful that you should instal on your RHEL system, or any Linux system for that matter, have been hand-picked by us.
