Welcome back everybody. Let's just continue on. So I have my virtual machine
here, it's running, the installation process is complete. I didn't take
any screenshots, nothing special there. Just let it finish till the end. That is
all, nothing else. So, go ahead and click on reboot, capture, okay, until we install
guest additions. So it's rebooting now. Just wait for it, shouldn't take that
long. And after it reboots we're gonna be doing several things which you will need
to do afterwards. The post installation procedure. Let's just...you can let
that run. You don't need to actually change it there to boot, or anything like
that. So please enter passphrase for this. If you remember, we have encrypted them,
and I have entered the decryption password. It is very important that you
remember your encryption keys, as I've stated previously. If you're the sort of
person that forgets them, write them down. If you don't feel like putting it, if you
feel like it you're gonna forget it, or something like that, better than not to
put it because you're gonna lock yourself out of your own disk, and that's
gonna be pretty bad. Anyway, what I want to say is that if you've decided to
actually get the Red Hat subscription for $50, you will be able to enable
certain repositories from which you will be able to pull the information from.
Okay, so license is not accepted, we will fix that shortly. Let's just click on I
accept license agreement. Done, finish configuration, and boot into your Red Hat
machine for the first time. As I said, we're gonna have access to certain
repositories, but no big deal there. You should really know, you should really
know how to do this, primarily because tomorrow when you're managing
Red Hat systems, you will need to enable individual subscriptions for machines,
and what machine has access to what sort of
packages from the Red Hat Network. Anyway, here it says subscription registration,
this assistant will guide you through the process of registering your system,
with Red Hat to receive software updates and other benefits. Okay,
so you don't need to register now. It is not necessary. Well, let's just go ahead
and say that we do want to register here, and then afterwards I will show you how
can you register in the post installation period as well
via the command line. So I'll just select yes I'd like to register now,
forward, I will register a subscription. Okay, so default. We do
not need proxies, done. Let's see what happens now. Come on, come on,
yep, there we go. So is it gonna show my password? No, it will not. So, login name, I
believe it was creator69. So original, right?
And I even misspelled it. There we go, there we go with that as well. So, just
type in the username that you have created on the Red Hat website, through
the process of registration, and then use the same password, no problems. If you
forgot it, of course you can go to Red Hat and say forgot password,
something of a kind, and it will reset it to your email, or something.
Now please enter the following for the system name. Okay, we
don't actually need to do that at the moment. We can just leave it at default.
Done, the subscription management registration is registering. You will only
be able to do this if you actually bought the license itself for one year,
where Red Hat provides updates, maintenance, and support.
Well, not maintenance, sorry, provides updates and support which is very nice. As I said,
you can at all times just go over to the website and basically start
a chat, and they will help you out with pretty
much everything that you need. Okay, so Red Hat Enterprise, Linux desktop,
support, type virtual, quantity one, done. Go for it...
aAtaching subscriptions, this should finish up shortly. Oh, by the way...okay, so
it's finished actually before I had a chance to show you, but it doesn't really
matter. I have the command standing by. Here's what I want to show
you, basically. There are these two commands which you can use in order to
register yourself from the command line, on a system which has already been
installed. So random guy shall now log in for the first time. No, don't do this to
me.
Yes, there we go. I almost thought I forgot my password which would be quite
embarrassing, but, oh, well, what can you really do about it? These things happen. I
will later on probably show you how to actually recover your password from a
loss as well, so that shouldn't be a problem.
Excellent! So, we have booted into Red Hat, and you can see it's a relatively simple
desktop without that much configuration. So, capture, so I'm just gonna leave it
here with English United Kingdom. You can change it to whatever you wish of course.
You can add additional keyboards here if you would like, but no I don't need any
additional keyboards. Okay, so you can also add some accounts here on the cloud,
but generally not a bright idea if you're gonna link your Facebook
account, or something like that. Here if I say Add Account, let me just
show you. You can say Google, oh, don't do this to me, add account. Okay, so I
got Google, onCloud, Facebook, some other things. All in all, if you have business
accounts that are directly related to this machine, or here physically. Well, not
physically, but the accounts that you own, that you use for business, and for
transactions, and stuff of a kind. I would then definitely suggest that to
actually link them with strong passwords, but I definitely would not suggest you
link, I don't know, a Facebook account which you use, basically, for
socializing, or something of a kind, or anything that falls into that category
of non professional things. So don't don't do that. If you're gonna have
professional account, sure. But, something for fun, no point. Just open up your
browser and log in. Let's just to go ahead and cancel that and press on next. Start
using Red Hat Enterprise Linux client, excellent! So now we're in Red Hat, and
okay it's gonna give us some getting started in the browser, but we don't
actually need that at the present because I know where things are. Feel free to read
through that if you wish. The desktop is fairly simplistic. This is gnome
if I'm not mistaken. And you don't have, you can install different desktops here with
more advanced graphical features, but we'll see what we can do later on to
actually change how this thing looks like. But, before we do
anything, I want to have a full screen mode. I don't want to be messing around
with this small image, and I'm sure you don't want to be looking at it either. So
go into devices, insert guest additions CD image. Could not find VirtualBox guest
additions disk image file. Do you wish to download this disk image file from the
Internet? Yes, I do. Thank you very much. You sure you want to
download VirtualBox from...ok, so which site is it?
Ok, so, yeah. Go ahead and download it. Make sure to check these things if they look
fishy, or something of a kind, then don't. Rather instead, copy the
address and check it out on the net. See if it's legit, or something of a kind. If
it's not then absolutely do not. While this is going on, while the network
operations manager is going on, let's just go into devices, network, network
settings. Make sure to change this from NAT to bridged adapter. But, I'm just
gonna leave it running for now while the download is going on because I don't
want to actually interfere with it in any way. But, change it from NAT to
bridged, and then under name select an adapter. As I have showed you in the
previous tutorials, make sure that you do that, don't forget to do it. Primarily
because, well, it's better to have a machine
with an individual LAN IP address that is separate and detached from the others,
but that can yet communicate without any problems of whatsoever, as opposed to it
going through NAT which is not really good. Not something that I favor, anyway.
Not that it's not that good. It's good for protection and firewalls. Just to
give you an example of what NAT is, its network address translation. So, let's say
you have a router, your own home router, that you use in your house that has been
given to you by your ISP provider for which you paid money, and then you have a
machine behind it, like a laptop, desktop, or a phone, or whatever,
it's completely irrelevant, then all the communication is done through that
router, and that router is the device which actually has a public IP address
from there all the requests are forwarded to the machines that actually
made those requests. So, if you're opening up a web browser, not a web browser, if
you're opening up a web site it's gonna go through the router, and then the
router is gonna receive the information and forward them to the correct
device within LAN. That is why we use network address translation protocol. But,
with the coming of the ipv6 addresses that's gonna become quite redundant.
Anyway, I'll just go ahead and see, oh, this is still downloading. Okay, so it's 50% now.
It is taking quite a while, but no worries there. I assure you it's gonna finish.
While it is going on, let's just have a look at some of the other
features that we have here. So this is where your name is
displayed, and you can play around with notifications, and this is also where you
click when you want to turn your machine off in terms of GUI. Into settings and
other things we will get into later, but for the time being, let's just go over
some of the basic options that you have here. So we've got settings, we got logout,
we got lock, we got power off. By the way for lock, in most of the
cases, you can use control alt l. It's a really good habit
for laptops. Especially if you leave them unattended, not a good idea. You can
check out the date, you have the calendar, it's fairly simple. Let's take a look at
it. The calendar, like any other calendar, nothing much to say there. Over here you
go to the battery if you're on a laptop, and under power
settings, aside from choosing your plan whether
it's extensive use and high performance, or whether it's power saving mode,
something of a kind, look, you have here a blank screen. So to blank the screen
after five minutes, don't do that. Well, these are my preferences. You can
choose them to whatever you want them to be. Automatic suspend, off, but when
battery power is critical, hibernate. You can choose power off or hibernate.
Surprisingly enough, it doesn't have that many options like I do on fedora, but
maybe, okay, no, apparently that's it. Not much there. But, you know when you're
using Linux machines, the batteries tend to last forever. They're very energy
efficient so to say. I don't want to get into all of these things at the moment.
In the follow-up tutorial, I will actually explain about the GUI,
and not the follow up tutorial but once we are through this mini chapter
within the course, through these three ways in which you can actually set up your
entire environment. Excellent! So, the VirtualBox guest
additions disk image file has been successfully downloaded, do you wish
to register this disk file image? Insert into the virtual drive, thank you very
much. Important software updates, install them.
Come on...
Okay, so VirtualBox additions contains software intended to be automatically
started, would you like to run it? This is the equivalent of you putting a CD into
your machine and running it, so just go ahead and run. It does require a password
so go ahead and type in your root password. Authenticating...oh,
come on.
Excellent! So it's running this in the terminal, and it should finish up shortly,
after which time I do believe that we're gonna need to perform reboot, but I'm
kind of hoping that we won't and it will catch it automatically. This process
it might take a while, but I don't think... the main guest module has failed? Okay, let's
see if this is gonna present some major issues. I don't know, it can have some
failures. It's still gonna work. The way I've experienced it, anyway, on my
other virtual machines. Press return to close this window,
excellent! So, are you gonna load it up now, or do we need to restart? Oh, we
definitely need a restart. So, install updates and restart. Sure, why not. Here we
go.
Okay, I don't want to capture. Excellent! So, let's just wait up until it boots and
see what happens. Remember, we are looking for a full screen because I really don't
feel like doing this on a small screen, and believe me neither will you. So, once
again we are prompted for a decryption password, and there you go. It's booting
up again. The boot process is not that slow, it's relatively fast. There are some
updates that have been applied as well, but we will need to perform additional
checkups on this, and these systems need to be updated quite frequently too.
Although, unlike Windows, it's not gonna force a restart on you. It's not gonna
restart in the middle of things while you're doing something important. That
will never happen with Linux, quite literally. And, pretty much, you do these
sort of updates manually with the packet managers on a regular basis, pretty much on
a daily basis. There are small updates. Although, the updates for Linux are
generally never as big as updates for Windows, so it's gonna take you a very
short amount of time to fill them up. And it doesn't take like a process of ages.
When you reset the machine you get that spinning circle, it says please do not
turn your computer off until the updates apply. Oh, that's a killer, it can be a bit
annoying. But, oh, well, what can you really do about it? Not much if
you want to apply updates in Windows, that is what you have to do, but in Linux
not so much. Let's see how far this is... come on, please. Okay, so it has popped a
little bit, but still gonna take a while. So I'm just gonna pause the tutorial
here and we will continue on in the next one, so you don't have to wait for this
to be over. Anyway, I bid you farewell until then.
