Hello everyone and welcome to another
tutorial video. This is the first video
of a 72 part series which will take you
from beginner to advanced in Linux
system administration. In this series we
will be using Red Hat Linux, and by the
end you should be ready to take the Red
Hat Certified System Administrator Exam.
Now before we get started, I would like
to take a quick moment to give a shout

take a look down there. So, without
further ado, let's get started!
Welcome everybody to this course. Today I
would like to introduce it to you, and to
go over a few things such as who is the
course meant for, who can attend the
course, what can you expect to gain from
it, and what can you expect to learn
would be a better way of putting it.
Anyway, this course I have designed
it to be a two-part course. One part will
be covering the very basics of Linux
as an operating system. So,
we will cover the graphical
user interface, then we will cover
terminal basic commands there. We will
dig a little bit deeper into the
advanced commands as well in the first
part. You will see how it is installed,
how you can modify things.
The first part of the course is
generally geared towards you
becoming comfortable using a Linux
operating system. So if you've never used
it before, if you've never
encountered anything of a kind before,
the first part of the course will be
great for you.
No steps will be skipped and you will be
able to learn everything from the ground up.
So, from the very basics and then we will
move on to the advanced stuff.
There are several ways of doing
this, of transitioning into Linux. And a
long time ago when I was using Windows, I
have transitioned into it by using first
a virtualized system, and then I was
and then I used a dual boot, and
then afterwards I pretty much switched
permanently to Linux. I still do have a
virtual machine of Windows 8.1, but I
rarely use it just for some applications,
or for some sort of testing, or something
of a kind. Anyway, I will show you methods
of installation, how you can install it
so you don't have to worry. Even though I
have Linux installed as my main machine,
don't worry about it, if you're using
Windows I will show you in great detail
how you can do this in Windows. How you
can install it on a virtual machine in
Windows, and how you can actually install
it as a dual boot. I know that a lot of
the people on the net, and in my
previous courses, have had problems
installing dual boot Linux systems with
Windows 8.1 and 8 due to the boot
system of Windows 8 and 8.1.
You don't have to worry about it. I will
show it to you in great detail how to do
it, so you can just follow the exact
step-by-step procedure, and that won't be
any sort of a problem or anything
of a kind. Anyway, the second part of the
course is basically geared towards
passing a Red Hat
certification. Red Hat certifications are
one of the most valued ones in the world,
and they are one of the top Linux
certificates that you can get. Pretty
much every server administrator, or
something of a kind, pretty much has one
of those. They are not cheap, I can tell
you that. They cost quite a bit of money,
but they are well worth it. I mean
a lot of the people out there when you
apply for a job as a server admin, or
something of a kind, they will ask you do
you have any certificates, or something
of a kind. And if you tell them that you
have a Red Hat certificate that means a
great deal. It carries a lot of weight. So
the second part of the course we will
deal with more advanced stuff. But, I
don't want you to worry about it. If
you're a beginner, I will cover all the
necessary things up to that point, so you
will be ready to dig in
to pretty much all the advanced terminal
commands. And then we will get down to
getting ourselves ready for that
certificate, for that exam, so that you
may obtain the certificate. Anyway, Red
Hat certificates are taken separately
from this course. So, you can take
them at any point of time, pretty much
anywhere in the world, but this course
that I have laid out here for you will
prepare you for it, and
you should be able to pass
it without any bigger problems. Anyway,
there are a few things which you will
require in order to follow through this
course, aside from an active internet
connection and the
computer. I wouldn't say that
you will necessarily need a Red Hat
edition of Linux, I'm just talking about
general stuff here. Later on when we get
into this tutorials, I will definitely
make an effort to show you exactly where
you can download, what and how you can
install each and every single one of
those things. So, you don't have to worry
about that. For the time being, I just
wanted to talk about, to tell you in
general what you will need and what you
should expect that you need to download,
or something of a kind. So,
you will most likely need a Red Hat
image which you can get from a Red Hat
website. And it's not free, it's 50 bucks,
something of a kind. The image itself is
free but the support for the image,
if you wish to use Red
Hat repositories, or something of a kind,
and believe me you will need to use them,
then the price is actually 50 bucks per
year. There are other more advanced
subscriptions that cost more, but this is
the cheapest one that you can take, and
this is honestly
the one that anyone getting into, anyone
starting will need. You won't need anything
more advanced, or anything of a kind.
Anyway, the second thing is
that you don't necessarily need to
install Red Hat, you don't necessarily
need to download Red Hat. You can
actually download CentOS which is
pretty much a copy of Red Hat. It's
completely free, and pretty much the same
commands apply which is very nice. But
you don't get the same level of support
as you do with Red Hat. Because on Red
Hat you can log
into your account to go to their website,
and you can start an instant chat with
their tech support, and they
will resolve any Red Hat issues that you
might happen to have. Which is fantastic,
and it doesn't really cost that much. I
mean 50 bucks a year that's
nothing. It's actually 49 but I just
rounded it to 50. Also, Red Hat has a free
distribution, open source
fedora for desktop users. So it's
completely open source, and Red Hat's
open source as well, and CentOS is open
source as well, but it's free of charge
as well. Fedora is free of charge so you
can download it from the Fedora website,
that's a Red Hat maintained distro. And,
as I said, it's free of charge, and it's
for desktop users, and that is what I use
on my system today. It's not that great
for servers, that's obvious. You can run
servers fine, no problems.
But, any bigger work, any serious work,
you're obviously not going to do on
Fedora. You would do it on CentOS
which is pretty much a copy
of Red Hat. And Red Hat doesn't have a
problem with it because CentOS doesn't
actually sell anything, they just give it
out for free. Red Hat doesn't actually
sell the operating system itself either,
they just sell the support for it,
anyway. And you will be able to install
CentOS, it will run without any further
problems as well. If you don't want to
pay those 50 bucks for the support,
you can install CentOS and the commands
will be pretty much the same. There might
be some slight variations, but you
shouldn't worry about it
that much. Although, I would strongly
recommend if you are a beginner to
just go ahead and get the Red Hat
edition. It's not that expensive, it's not
a killer or something of a kind, it's for
the whole year. Anyway, you will also need
VirtualBox, a virtualizer on your Windows
machines. Because even though my main
machine runs on Linux, I will show you in
detail how to perform an installation on
Windows in a virtualized environment, how to virtualize Linux
on your Windows system. I will also show
you how to dual boot with Windows 8.1 as
well, and how you can make this smooth
transition, if you're a Windows user, to a
Linux based platform. There are numerous
reasons for this which we will cover in
the follow up lectures. But for the time
being, these are
some general things that you
will need, and see if you fit into any of
the groups of people, that I have stated
previously, that could benefit, that will
benefit from this particular course.
Until then I bid you all farewell, and if
you are here, if you decided to take this
course, it's a huge step, and I wish you a
lot of luck with it.
