Welcome all to this tutorial. Today I'm
going to show you how to and where to
download Red Hat,
and how can you install it on VirtualBox.
Now even though I know I've said that
this is going to be done in Windows 8.1, and
here I have indeed showed you how to
actually install VirtualBox in Windows
8.1, now I mainly want to show you how to
use VirtualBox, and how to actually
install an operating system here in your
virtualized environment. It does not
matter if you are using Mac, Linux, BSD,
Windows, and pretty much whatever else is
out there that is supported by virtual
box, or that supports VirtualBox, the
interface is the same. There are minor
trivial differences which basically do
not matter at all. I can't imagine why
they would. So, I'm just gonna use a
VirtualBox in my physical machine which
is Fedora,
but the interface is exactly the same. I
could obviously do it here in a virtual
machine, but to install a virtual machine
within a virtual machine, yeah, I would
need, I basically could do it but it
would completely eat up my RAM. If you just
take a look at this, where is it, over
here, this is the current
load of my system. So, it's a bit
ridiculous, right? So the four cores of
the processor...look at the
load. I mean, there it's like 39, 41, 38, 45,
something like that, and look at the RAM
usage. I have around 8 gigs of RAM, out of
those 8 gigs I am using 6. So many things
running on my computer at the moment. So
I'm just gonna use a VirtualBox which
is here on my Linux system, which I am
spinning around the screen now, but the
procedure is exactly the same. I mean,
just take a look at this one, it
says Oracle VM VirtualBox manager. And
now take a look at this one in Windows,
they are exactly the same. Maybe there
are some design differences at the
corners, and bit of difference in terms
of colors, but that's about it.
There's pretty much no difference in
terms of functionality or what you do
here.
Anyway, I have Red Hat here
running. Okay, we're not gonna need that.
Power off the machine, and I'm gonna
delete this one, delete all files, just so
that I can repeat the installation
procedure for you. I did go through it
once. I mean, I have went through CentOS
once, and everything like that. I like
to go through them before I actually
begin a tutorial. Just because sometimes
you encounter problems, flaws, and if I do
encounter them I like to report them
during your tutorials, and show people
how to resolve them in advance. Just in
case they encounter them. Anyway, I'll
just move that out of the way. So you
just open up your browser on whatever
operating system you are using, and if
you're using Windows it doesn't matter.
Just open up your browser as I have
opened it. Now go ahead and type in to
your search engine, I don't know, like red hat,
amazing...
Red Hat, okay, Red Hat the world's
open-source leader. This is their website,
and here you would log in. So you do need
to create an account in order to do this.
Creating an account on Red Hat is
absolutely free. And once you actually
create an account there, head over to
this link, but you can navigate on the
page without problems. But, I'm just gonna
give you a link as the worst case
scenario I guess. Let me just zoom it in.
So it's here, basically, in the downloads
section. It's not that hard to find. There
are a lot of Linux distros out there.
There are a lot of different versions of
Red Hat depending for what purpose are
you downloading. And Red Hat, even
though it is open source, it is not free.
Even though something is open source does
not necessarily have to mean that it's
free of charge.
Although, Red Hat itself is an operating
system, they don't actually charge for
that. Rather, instead, they charge for the
support. So if you want to access the
repositories for which you can download
software and updates, and so on and so
forth, you will need to pay a yearly fee.
Now the good news is that the yearly fee
is like $50 for regular users, for
companies, or something like that, it can
go
up to 3k, or something of a kind. But, hey,
you're a regular user so it's only 50
bucks. And if
you don't want to pay
50 bucks, or something like that,
for the support, or something of a kind,
it's fine.
There is something called CentOS on my
other page. Well, just type into
your search engine CentOS. I'm using
Firefox here but it doesn't really matter.
Whichever operating system, whichever
browser, CentOS, go and visit their page.
I'm just gonna close this one because I
have another one open, and there you go.
CentOS is pretty much a copy of Red Hat.
Red Hat does not have a problem with
that. Just a heads up info, or
something of a kind.
Red Hat does not have a problem with
CentOS. In fact, they cooperate on a lot
of things. Here's why, CentOS doesn't
actually charge for anything. It's
completely free, it's open source. You can
download it for free
without any sort of registration
required, and it gives their users a
chance to see what Red Hat can be really
like. Furthermore, one of the
fundamental differences between CentOS
and red hat is the support. Pretty much
everything else is more or less the same.
So you can download it and you should be
able to follow through the tutorial
without any bigger difficulties of
whatsoever, as things will be pretty much
same. If you do encounter some
problems please let me know, I
will be more than happy to jump in and
help you out. Now there are a few things
that you should pay attention here. When
downloading CentOS, make sure that you
know whether your system is a 32-bit or
a 64-bit operating system. If it's 64-bit
it won't matter, you will be able to run
32-bit images and 64-bit images without
any problems. However, if it is a 32-bit
system then you will not be able to run
64-bit images. And I have made a
bit of a spin here with words, but I
think you get the meaning. Make sure that
you know whether it's 32-bit or 64-bit.
Anyway, so you have a DVD ISO, everything
ISO, minimal ISO, you can certainly choose
one of these three. But, what I would
recommend if you're going to download
CentOS,
just to go to if this is not for you,
alternative downloads might be. So just
go ahead and click here, this will give
you a choice. So you have CentOS 7,
and the version of the 7, and you
have it only for 64-bit systems if I'm not
mistaken. And down below you have
CentOS 6 if you're using a 32-bit system,
just go ahead and download this one
where it says i386. Just in case you are
using a 32-bit system, please keep in
mind a lot of people make this mistake
and then they can't install it into
VirtualBox, they get a lot of errors, and
they can't figure out what is wrong. But,
eventually they do and it's not a major
obstacle I would say, but it certainly
does cause a loss of time. Just a bit of
attention and you can save yourselves a
lot of trouble. Now I won't be showing
the installation for CentOS but it's
it's almost exactly the
same, if not exactly the same. Red Hat,
CentOS, and Fedora, they're pretty much
the same, so no problems there. Fedora is
just an open source, free distro
maintained by Red Hat that is for
desktop users. It's very nice. That is the
one that I like to use as my desktop
machine. Well, that's not true. I ran it
on my laptop and it has served me
extremely well. Anyway, we are now on Red
Hat's website. I have logged into my
account,
and I am here at the
downloads page, download the product. So
it says Red Hat Enterprise Linux desktop,
that is the one that you will need, and
it says 7.1 latest, excellent!
64-bit architecture. Prior to this you're
gonna have a downloads page, and stuff of
a kind. Browse the site, see
what suits you, but this is the one that
I have chosen to download. If you want
another version of it,
just go to the download section on the
site. As soon as you log in you will be,
as soon as you create the actual account,
which is fairly simple to do, you will be
given an option to actually go to the
download section, and there you can
pretty much
choose whatever you want. I have chosen
to download Red Hat Enterprise Linux for
desktops. I know it says
that it's perhaps not the best for
servers, or something like that,
but believe me you can install packages,
you can configure it, and it can run as a
fantastic server. And, besides, it has
pretty much all the functionalities
as the other ones do. However, you
do need to bother with the installation
of extra packages, configuration, and
additional stuff, as opposed to some
other variations where you don't
need to do this. And, for example,
Red Hat server, or something of a kind, it
would support file sizes up to a
petabyte, or something of a kind, which is
humongous!
You're definitely not going to need that
realistically ever. I mean unless you
work in a large company, or something of
a kind, and then they have these products.
But the management, the commands, the
setup, everything is pretty much the same,
there's very little difference. So, go
ahead and select Red Hat 7.1 binary DVD
download. You don't need the
supplementary DVD. Just go ahead and
download the binary DVD, the middle one,
click on the download, and it's gonna
download for you. It's 3.57
gigabytes so it might take a while
for you to download. I'm not gonna
download it now but I have downloaded it
previously. You can see it here. I have
actually downloaded it twice because the
first download was incorrect, it
didn't really work out. So I just
downloaded it again which was really a
painful experience, as it is a rather
large file, and I don't have a really
fast internet connect, that fast of an
internet connection. Here it's like five
megabits, so that was kind of
painful. But, OK, anyway,
feel free to pause the tutorial here and
then continue on when the download is done,
because you
need this file in order to proceed.
Anyway, just go ahead, let's just go ahead
and start up our VirtualBox so that we
may actually begin the installation
process.
Anyway, as I have said...OK, so, where is it,
where is it? As I have said, I'm only
showing you the application here,
and the usage of this application is
exactly the same across all supported
platforms, pretty much. So on Windows,
Linux, Mac, whatever, the setup is pretty
much the same. There is nothing
fundamentally different that you need to
do in order to perform the setup there.
The installation process is
different on different platforms, but the
application itself, the software, it's not.
It's pretty much the same.
It displays the same sort of information,
the process is exactly the same, so no
worries there. Okay, so let's go and
actually create our Red Hat machine. I'm
gonna go ahead and just minimize this
shall we. And I don't really need this.
Let's just, I like to keep this part
open so I know what is going on in the
background. Well, maybe not in the
background, but I know the load on my
system. I know that there are utilities
that you can put on the side that can be
really useful, but for the time being I'm
just gonna leave it as it is so I can
monitor the usage. You can see this is
ridiculous. It gets up to 90% in all four
cores. Ah, that's a joy.
Anyway, even though it's an i7 processor...
Anyway, let's just go ahead and click on
new, select the name of our virtual
machine, what should it be? Let's call it
Red Hat.
You see it says type, Linux. Okay, so it
recognized that by default, and it also
said that the version, Red Hat 64-bit.
Make sure that you select the
proper version for yourself, either
32-bit or 64-bit depending on what you
have downloaded, and depending on what
your system supports. So, please be aware
of that, don't make that mistake.
Anyway, it's 64-bit for me, so go ahead
and click on next. I would recommend
giving it around, I'm gonna give it
around 1.2 gigs of RAM. OK, so I know that
on the net the information exists, and
this is really true that Linux systems
can run on 56 megabytes of RAM, so 56
megabytes of RAM is actually doable on a
Linux system. You can actually run it
which is hilarious. I know, right, 56
megabytes? But, that's not really
recommended. Depending on what
you're gonna do, that is the amount of
RAM that you're going to require. But
if you have RAM to spare, I would
recommend giving it 1.2 for smooth
operations. However, you can also give it
750 megabytes, and you can even go
down to I think
250 megabytes. But you shouldn't really
go lower than 750 if you don't
absolutely need to. Primarily, because, you
might experience some lag, let's put it
so. It's gonna work
that's for sure, it's gonna function, but
you might experience some lag during
your operations. But, anyway, assign
either 1.2 gigs or whatever else you
can spare, that is below 1.2 gigs, for
this purpose. However, as I said, I will
show three separate methods of how you
can do this, how you can actually run
Red Hat parallel to your Windows machine.
You can choose either three of them, see
what works out for you. If you see one
and if you perform that set up, and if
you like it, you can just take a look at
the other two so you can see what else
is possible. But, you don't necessarily
need to do all three of them.
Anyway, so it's 1.2...see if we
can aim it a little bit better...
1.23. Okay, so let's go next. Create a
virtual hard drive now, create, VDI hard
drive file type, okay, next. Dynamically
allocated, next, and now we need to
provide storage. Okay, this is getting a
little bit annoying, so I'm gonna move it
out of the way. But, there we go.
Here I have my temperature gadget. I like
to keep an eye on that as well. Primarily,
because, you've seen the load on my CPU
and all of that. It's a good idea to
keep an eye on these things. Anyway, just
assign it around, I'm gonna give it 32
gigabytes of space on my hard drive, and
that's gonna be acceptable. But, you
can assign it whatever you can spare. And
okay, so maybe I can give it 128
gigabytes, but that's not really gonna
make a difference. I'm just doing it to
show you basically what you can do. I
have a lot of space here that I can use
a lot. Anyway, go ahead and
click on create. But if you don't have
assign whatever you can spare. 32 gigs
would be very nice. Anyway, now you need
to go ahead and right click
settings, system, oh sorry not system,
storage. You have controller IDE and down
below it says empty. Go ahead and click
on empty. In the upper right corner you
have choose virtual cd/dvd disk or a
physical drive, so you can actually
insert a CD, a pre burned CD into your
machine, and then use that one. But, why
bother when you have a an ISO image
ready standing by? So just click on
choose a virtual CD drive, and it doesn't
matter on what system you are, again, you
will be prompted with a file manager
here, file browser, and then you will be
able to navigate to the folder where you
have downloaded your
Red Hat from your web, Red Hat Linux
distribution from the website. So here I
have downloaded mine, here it's DVD one.
Okay, so open, its selected there, I click
OK, and then from here I'm gonna actually
perform the installation. But, I'm running
a little bit short on time, so I'm gonna
call the tutorial here and show you the,
and continue showing you the
installation process in part 2.
