When compared to installing other distributions of Linux, Red Hat Enterprise Linux is installed in a somewhat different manner. This will walk you through the process of installing and configuring RHEL on your system.
Red Hat Enterprise Linux, sometimes known as RHEL, is an enterprise-level Linux distribution that serves as more than simply an operating system or server solution. It is more of an ecosystem that has been developed for and around businesses. All types of businesses, from multinational corporations to essential infrastructures like banks and government agencies, put their confidence in the Red Hat system.
Even if it is enterprise-grade software, it does not imply that individuals who do not belong to businesses are unable to receive a taste of what it has to offer. You are welcome to give Red Hat Enterprise Linux a try right now by downloading a free copy of the operating system and subscribing to it at no cost.
You will be walked through the process of downloading and installing Red Hat Enterprise Linux using this tutorial.
Grab the RHEL ISO!
You need the operating system’s disk image in order to install a new operating system, regardless of whether you are installing it on a physical disk or a virtual machine (ISO). The ISO file that you downloaded contains crucial system and setup files that are required for a successful installation.
Due to the size of the RHEL ISO file, which is around 10 GB, you will need to ensure that your USB or DVD has sufficient free space to store the installation data. In such case, reclaiming storage space is as simple as utilizing the terminal.
Signing up for an account is the first thing you need to do in order to obtain the most recent RHEL ISO. On the website, navigate to the Register link and fill out the required fields with your information. It’s possible that we’ll send you a confirmation email to complete the activation of your account. Bring the procedure of unlocking the ISO download to a successful conclusion.
Get the Virtual Machine all set up
Instead of setting up a virtual environment, those of you who plan to install Red Hat on bare metal on your computers will need to generate a bootable USB drive for the installation process. If you intend to install RHEL directly on your machine, you may skip this step and go to the next one.
If you have experience configuring virtual machines in the past, this should be a piece of cake for you, and you may as well skip to the next step if you’re comfortable doing so. Continue reading if you are not familiar with the procedure involved in this process. We’re going to go ahead and assume that you’ve already downloaded and installed VirtualBox. If that is the case, this tutorial on how to install VirtualBox will be of assistance.
Launch VirtualBox, then select the New option from the menu. Choose Linux and Red Hat (64-bit) as the version from the drop-down menu under machine Type. Set aside at least 3096 megabytes’ worth of memory space. Regarding the size of the hard disk, you have the option of keeping the settings as they are or increasing the stakes. However, you shouldn’t make the size smaller.
When you are finished configuring the settings for the system, click the Create button. You ought should be able to locate your freshly constructed virtual machine on the left panel at this point.
After the fundamental parameters have been completed, it is necessary to provide the virtual machine with an ISO from which it may read the installation files.
To access the storage settings for the virtual machine, navigate to the Settings menu and click on the Storage tab. Under Controller: IDE, choose the RHEL ISO file you previously downloaded by clicking on the icon that looks like a disk and then selecting the file from the drop-down menu that appears.
Start your freshly formed virtual machine (VM) by clicking the Start button if you are installing RHEL on a virtual machine. For those who have already built a bootable USB drive, simply plug it in and start the computer from the USB drive.
Using the arrow keys, navigate to the Install Red Hat Enterprise Linux System option on the GRUB bootloader screen, and then press the Enter key.
You should see a screen that allows you to choose the language and the region that you want to use. After you have confirmed your choices, you will get a follow-up warning that will warn you that the build version is not ready for a production environment and will ask you to approve the installation or roll-back modifications. If you click the “Confirm” button, the prompt will disappear.
Caution is warranted if you plan to install RHEL on bare metal; you should really reconsider your decision. If you are truly intent on doing this, our recommendation is that you acquire a ready-to-deploy version of RHEL that costs money. Because this is a free version, the build is an experimental one, which means that it has the potential to be unstable and riddled with bugs.
Those of you using virtual machines can advance without risk by clicking the button that says “I wish to proceed.” This should take you to the RHEL installation dashboard, where you may do a wide variety of key options, like setting up user profiles, partitioning the drive, and so on.
After making your selection, click the Done button after selecting the virtual drive that you had previously designated for the RHEL installation.
After that, you will need to make a user profile so that you can log into Red Hat after it has been installed. The procedure is identical to that of installing Linux via any other method. You should not have any problems proceeding if you have previous experience installing any Linux distribution.
To finish things off, you’ll need to select a one-of-a-kind and long root password for the admin account. After you have completed all of the steps required for the pre-installation process, you may install Red Hat Enterprise Linux on your computer by selecting the Begin Installation button.
Grab a cup of coffee, because it might take a few minutes, depending on the hardware of your system or the resources that you’ve allotted to the virtual machine.
When the installation process is complete, you will be prompted to press the Reboot button in order to restart your device and boot into a brand new RHEL installation. If this is your first time signing in, you may be asked to agree to the licensing information when you are requested to do so.
Examine the terms and conditions of use with extreme caution. If you are pleased with the document, choose the checkbox that says “I agree to the licensing agreement,” and then click the “Finish Configuration” button to complete the process. It will immediately take you to the login page, which is referred to as the GNOME Display Manager (GDM) on RHEL.
You now have Red Hat Enterprise Linux up and running on your desktop; all you need to do is log into the account using the credentials you established during the installation process.
Those of you who have already installed it on VirtualBox should remember to eject the ISO file before starting the computer, since failing to do so might cause a boot-time conflict. The RHEL installation procedure has now been completely finished. It is quite easy to understand, despite the fact that it is not as user-friendly and streamlined as distributions that utilize Calamares.
Wrapping Up the Post-Installation Process
After the installation procedure has been completed, it is only normal to get excited about playing about with the distribution, experimenting with commands, and doing other related things. However, there is a significant after-installation duty that you are responsible for doing. If you don’t do that, you won’t be able to install any software, even something as simple as Neofetch, and you won’t be able to make any modifications to the system.
RHEL is an operating system that operates based on subscriptions, as was described earlier. Even the most fundamental services need you to obtain a license, which is free of charge.
Launch a terminal and register yourself with the subscription manager to activate your free membership. Doing so will make your subscription active.
subscription-manager register –username yourusername –password yourpassword
After that, continue with the next step, which is to attach the subscription management.
subscription-manager attach –auto
You should now be able to execute commands, install packages, and update your system, which, by the way, is the next item you need to complete. If everything is in order, you should now be able to do any of these things.
sudo dnf update
After you have successfully registered and activated your Red Hat system, you should do an update as soon as possible. Because this is a beta version that has not yet been released, the developers will be doing a lot of testing.
Therefore, each update carries with it the possibility of either rendering your system inoperable or rendering it more stable. Maintaining an up-to-date operating system is recommended, despite the fact that you won’t be able to determine which update performs which function.
Protecting Your RHEL Server from Unauthorized Access
Even if your RHEL system is operational, there is no guarantee that it is safe to use in practical terms. If you want to use it as a server, you may as well put in the work to reinforce it before you start using it.
Your system may be kept secure and administered in a risk-free manner with the help of any number of free and open-source security solutions. We have selected a select few applications that you will want to install on your RHEL system, or any Linux system for that matter, that we have chosen by hand.
