Module 1.2 - Lab setup and virtual machine creation

Today I am going to walk you through setting up our Linux lab. We have two choices; you connect to the servers I deployed on the cloud which is very easy to, no need to set up, or you follow the steps I will be mentioning in setting a personal one for yourselves. Either way, sooner or later, you will still have to set up a private lab in the advent of the one on the cloud being inaccessible.

Let’s roll.

Have you heard of virtualization?
Well, you will learn a few things about it today and learn in detail when we get to the module.

In the days when IT started, if you need to run about 15 Operating systems (OS’s), you will need to buy 15 PC’s or 15 servers but as technology began to evolve, a swift way of managing many OS’s on one box became possible by a technology called virtualization. Imagine running about 3 OS’s swiftly on just your one hardware, it can only be the power of virtualization and that is what we are going to set up right away on your system.
We will be installing two different OS’s, RHEL and Ubuntu by using a virtualization software called hypervisor. Any software that does virtualization works on a hypervisor. A hypervisor is a virtual machine monitor (VMM), a process that allows one host computer to support multiple guests. Examples of virtualization software or I’ll rather say examples of hypervisors are VMware workstation, ESXI, hyper V, virtual box, KVM, RHEV, XEN, etc.

ESXi and VMware workstation hypervisors are developed by the company VMware. Hyper V hypervisor is developed by Microsoft, virtual box hypervisor is developed by Oracle, RHEV is developed by Red Hat, etc.

In our setup, the hypervisor we will be using is the Virtual box. If you have VMware workstation, we can also use it, they are kind of similar and kind of follow the same process of installation. Both hypervisors are type 2 hypervisor.

Oh sorry!!!, I forgot to mention that we have type 1, type 2 and hybrid hypervisors. Some developers don’t believe that there is a hybrid hypervisor anyways but if you ask me, “Na who I go ask”. Lol.
We will talk about the types of hypervisors in detail when we get to the module as i mentioned.

Moving forward, below are the steps we will follow for those using windows OS. For those using MAC, I’m so sorry, I don’t use MAC so I can’t take a screenshot but steps are similar. Email me if you have issues, we may have a remote session if I am less busy and walk you through it, but you must make sure you have tried your best first.

1. Download virtualization software. In this case, a virtual box. You may use the link below. Click on the type of OS you are using
https://www.virtualbox.org/wiki/Downloads (about 163mb)
when it’s done downloading, check your downloads. you will get something like this

1. Download virtualization software. In this case, a virtual box. You may use the link below. Click on the type of OS you are using
https://www.virtualbox.org/wiki/Downloads (about 163mb)
when it’s done downloading, check your downloads. you will get something like this

2. Double click on the image above to run the installation or right-click on it and click on “run as an administrator”. You will get an image like the one below, click on next button

3. After clicking on the Next button in the image above, you will get an image like the one below, click on the Next button

4. After clicking on the Next button in the image above, you will get an image like the one below, click on the Next button

5. After clicking on the Next button in the image above, you will get an image like the one below, click on yes, another box pops up, click on install

6. You will be asked if you want to make changes to your PC, click yes.
you will get an image like the one below, click on install

7. When the installation is complete, you will get an image like the one below, click on finish. The checked box will start the VM after the installation.

8. After installation, you will have an image like the one below

Now we have our hypervisor ready, we can start creating our virtual machines (VM)
I earlier said we will be creating two VM’s but we may need to create more than that when we begin to do a lot of stuff like Active Directory (AD) configuration, DNS, DHCP, NFS, NAS, LADP, and the likes. We will get there!!! Home wasn’t built in a day.

CREATING VIRTUAL MACHINES (VM)

Steps
1. Download RHEL OS, ISO image if you don’t have any. You can download it from the link below.
https://access.redhat.com/downloads/content/479/ver=/rhel---8/8.1/x86_64/product-software

(It’s about 7.31 GB) even if I configure a public FTP site and dump it there, you will still have to download it. You can use the cloud server if you can’t afford the data size for now.
OR
You can also use the installation CD if you have any, but be careful not to wipe the whole OS off your system.
NB: I changed my mind, we use RHEL 8 instead of RHEL 7. RHEL 8 standard version came out this year even when Red Hat hasn’t finished the update of RHEL 7 minor version yet. Can you imagine the IT world/business? and this is my first time of using RHEL 8 as well…Let’s upgrade and follow the trend as well “jorr”.
Please use RHEL 7 if your internet is bad and finding it difficult to download, its about 4 GB. There can’t be much difference in installation process between the two.

2. From the image above, that is, step 8, click on the new button, you will get a box like this below, give any VM name you like, make type Linux and version 64-bit, click on next

Class Activity 1.3: Which company developed the KVM hypervisor?

saxwizard:
interesting Read...... thank you sir






the relationship between them is that they are various distribution/variant of LINUX OS,

they are commonly used by enterprises as they are open source and can be modified.

Nice one. Answer is on point

peemeeks:
The common ties between them is that they are built using Unix.

They both run on Command Line Interface (CLI)
They are Open source - free to use although Red Hat slightly vary in this regard.

The difference between both is that Ubuntu is designed for personal use while RedHat tilt towards enterprise (Commercial) usage.

I try small abi

Yeah, you tried. However,there is Ubuntu Server as well. The Ubuntu desktop may be used personally.

Narnah:


They operate on Linus kernel

I guess you meant they both operate on Linux kernel. that's correct

Royalsleek22:

correct

developed by Open Virtualization Alliance (OVA) and I also think it's open source

thanks so much for the effort..

Red hat enterprise Linux binary DVD, Version 7 or 8

Check by the left side where there is product, click on red hat enterprise Linux. It has to be a binary DVD. I made a screen shot of what it should be on step 1 in creating VM.

You can install 8.1 DVD.......

Always try to download directly from OEM nextime. 3rd party can be risky.

thanks so much boss. Really appreciate

Damn!! 7.5gb?? I will just wait for the server you deploy!
Maybe later.
