So, what do you need to install Red Hat Enterprise Linux?
Well, the answer is, it depends on the type of installation that you want to perform.
Is it going to be a physical installation, cloud-based, or virtual?
And is it with or without a graphical user interface?
And what exactly are you going to do with the server?
Based on the answer to these questions in real life, you can get very different hardware
requirements.
Most important for us right now is that you know what to do to follow along in this class.
Well, there's only one simple answer, and that is, you need to install a virtual machine
in this class.
Don't use containers, don't use WSL, don't use cloud instances, because you will miss
functionality that is important for the exam.
Install a virtual machine.
So what does this virtual machine need?
Well, two gigabytes of RAM.
If you have it, better use four.
It will run better on four gigabytes of RAM, 20 gigs of disk space, a network connection,
and optical drive or access to the DVD ISO.
Before I'm going to show you how to perform a basic installation, let me show you how
to create the virtual machine environment.
Okay, so I'm not going to show you how to perform every different types of virtual machine
creation.
I'm showing you VMware Fusion on macOS.
I definitely can recommend VMware Fusion if you're using macOS or VMware Workstation,
if you are using Windows or Linux to create your virtual machine.
And then what do you need to do?
Well, you need to specify how you want to install.
I want to install from a disk or image.
Then I'm continuing, and you need to specify which disk or image you want to use.
Either you scroll down from a list of images that you've used before, or you use your finder
or whatever it's called to browse to the appropriate image.
And then you click continue.
Then it's asking, what are you installing?
Well, as RHEL 10 was only released a week ago, I don't see a RHEL 10 version yet, but
I do see Red Hat Enterprise Linux 9.
So as that comes closest, let me go for Red Hat Enterprise Linux 9.
Now we see the hardware overview.
I don't like the fact that it only has two gigs of RAM.
So I'm going to change that by clicking customize settings.
And there, I need to give my virtual machine a name.
And give it any name that you want.
It's only for your own organizational purposes.
OK, so next you can see the settings window.
And in the settings window, the most important is processes and memory.
Two processor cores, that's OK.
But do yourself a favor and set your memory to four gigs in total.
And then you can just close it, after which you can see your RHCSA virtual machine ready
to run.
In the next video, you'll learn how to perform an installation of RHEL 10.
