Hello and welcome to St..
OS installation this is the fun part.
Yes this is where we gonna get our hands dirty.
We can go ahead and download the center as iso image file from the from the Internet.
Once we have it downloaded then we will go to the installation a complete installation of sent OS Linux
operating system.
So are you ready.
So now I want you to go ahead and open up your browser any browser that you prefer.
Whether it's i e Firefox or Chrome.
So let's go in.
I have my browser open already.
I will go into Google now.
The second step is you could use google or any search engine that you like.
And I want you to type sent OS download and hit enter.
Once you hit enter you will get the first link.
I want you to go and click on it or you could simply go in and click on download.
But first let's go to this first link.
So the first link or the first page you will see download S.O.S.
Now sometimes you will see three options in this page.
One is a DVD ISO.
Second one is everything DVD ISO.
And third one is minimal ISIL.
If you are seeing three or if you are seeing two right now it doesn't matter because what we need is
DVD ISIL.
This is the one that we need to click on.
So go ahead and click on DVD.
So this will bring you to the links where the ISIS images are saved.
So all those links are actually the links to the servers or the and oftentimes referred to as mirrors
these mirrors.
When you click on it it will take you to the file where the file location is.
So go ahead and pick any one of your choice I'll recommend that you pick the first one.
So go ahead and click on the first one.
Once you click on the first one it will ask you a prompt you to save the file you have to see the file
to you to the location so go and click ok if you do not know where the file is being saved.
You see this little arrow here.
If you are using the Firefox you will see this little arrow here click on it and it will tell you that
it is being downloaded right now.
I do not want to download because I have already downloaded that file previously because I don't want
it to waste time your time and my time to go through the complete download.
So let's minimize this page.
Let's go to a desktop because all my downloads go into my desktop.
Now you already have this S.O.S file.
OK.
Now I want you to go ahead and click on a double click on your Oracle watch tool box the icon you have
on your desktop.
If you do not have that icon your desktop then you go to the start menu and find that up and you will
go ahead and start from here.
When it opens up you will see the my first Linux for Linux VM.
The one we created earlier these two you probably not going to see it because I was playing around with
some windows washing machine.
Anyway it's just you could just ignore them.
Click on the first.
My first Linux VM and click on start.
Now this is powering up your words from machine.
This is exactly the same way as if you powering on your physical machine by pressing the button on it.
So now it is asking since this virtual machine has no operating system.
So by default is asking you to attach a virtual disk to it.
So it is asking where is the location of that which will disk which you want to install that operating
system.
So go ahead and click on this little icon which will browse us to our desktop where we have our iso
image saved.
Click on this little one and you will see right here on our desktop folder.
When you click on our desktop you come down and you will see right here is a Santo 0 7 which we have
downloaded a few minutes ago.
So go ahead and click on open and click on start.
By the way this top thing right here is telling you you have option to capture a keyboard option turn
on this will cause the opposite virtual machine or automatic capture you could just go ahead and cancel
it.
Now it's telling you at the screen is telling you this is a center where seven install center with seven
test this media and install it sent to us seven or do the troubleshooting right now by default test
this media and install Santa a seven is selected you do not want to test this media usually this option
is picked when you have a DVD install and the reason we do the test because sometimes a DVD have scratches
on it that's why we wanted to go through the test.
So since this is iso image we don't do that.
So go ahead and hit up arrow key on your keyboard and it will select or highlight the top one it's safe
to install Santo 7.
And now go ahead and hit enter.
It is actually bringing the iso image copying the files that are needed to actually install the operating
system.
So it will go through certain star processes.
It will start up the gooey.
That will allow us to go through the installation of the Linux S.O.S operating system.
We will give it a minute for the goal to come up she right here says starting installer one moment and
the installer.
The gooey itself is called Anaconda.
This is the name they have given.
Why.
I don't know but this is the name.
If you wanted to keep in mind you just remember that Anaconda is the gooey tool or the gooey Vizard
that will help you to install the Linux operating system.
Now you are on the Welcome to Centro a seven welcome page.
What language would you like to use during the installation.
By default English and I am in United States so I'll pick English United States if you are in any other
country will recommend as you pick that country or if you want to pick a different language you could
pick that.
However I am not going to tell you how you could go through the installation with different language
anyway so I would prefer that you stay on English and then you definitely you could pick a different
country.
Now go ahead and click on continue at the bottom right.
OK so now it says please complete items mark with this action.
This icon before continuing to the next step.
Now the date and time is the first one we have already preselected America's New York Time Zone.
If you wanted to change the time zone depending on which time zone you are in.
Go ahead and click on it and change the time zone keyboard it by default it selects English and U.S.
language support.
Again English United States installations source local media which means that we are installing the
operating system through the local iso image.
So it's already been selected.
Perfect.
Next stop software selection.
This is where it has by default the software selection as minimal install.
If you leave that as is minimal install then it will install the Linux operating system but it will
not have any gooey on it.
Well remember one thing most of the time in corporate environment there are no gooey on Linux.
But since we are going through some practice we will go to some goofy practices as well because I do
want you to know how gooey works in Linux as well.
So we'll go ahead and click on software selection and that's where we will pick up a couple of different
additional software that are required in the minimum installed.
We have other options as well if you wanted to use sys administration tools or any other tools you could
pick them.
We can leave as default compute node.
Anything any debugging tools directory clients hardware monitoring tools development tools.
Most of these tools are used by developers since we are now going through the development training.
We will leave that as is infrastructure server.
What type of server are we going to run on this machine.
I will tell you you could pick any one that you think you might need it later on you could pick the
DNS server for now because we are going to code DNS which is bind in this training so you could pick
DNS if you do not pick DNS server at this time there is no issue.
We could always install DNS server or package later on.
But anyway just to show you how it works I just selected one DNS name server.
Anything else that you wanted to select here you could.
If you don't want to just follow my lead then let's go to the next one.
File and Print Server.
You can leave everything as is I said basic web server we don't need it virtualization host and no server
of it.
Yes.
This is where we have to come in and if you notice as you are going down all the other options that
were available on the base environment are all actually added here as well.
So don't worry about it they are repetitive.
It's not that this option will have a different DNS server and that this base environment.
So right now we are in the server with Chloe environment.
I want you to go down and pick K.D. E which is KDE is a plasma workspace a highly configured graphical
user interface.
I also want you to pick Java platform because if you are running certain application that requires Java
we could bring that up.
Um let's see what we have we have all the virtualization tool
okay.
I think we are good here with the KDE.
Now the next one is genome desktop.
Now genome desktop are are the desktop that also provide some type of applications for the user let's
say if you want to use Firefox or if you want to use calculators or something on the good side then
you could select this desktop as well so go ahead and click on genome applications.
Any other tools we need Internet application email chat videoconferencing software we don't want that
because most likely in corporate environment you will not be using any of these KDE plasma workstation
workspaces development and creative workstation.
And that's pretty much it.
You don't really need any other applications or add ons for the selected environment.
Now go ahead and click done now you will see this option right here.
It will tell you checking software dependency it means it is going to our ISO image and asking that
ISO image hey this user has selected these these many packages do you have these packages for me to
install on this operating system it's going to say hey OK no problem let me go ahead and check that.
So it's or is checking the source and it's checking the software dependency as well.
So what is needed for those add ons that we need to install installation destination wireless running
we'll go to the next one it's his installation destination now how do we want to protection are disk
installation destination right.
Nice is automatic partitioning selected if you want to change that meaning.
Right now we have 10 gig.
This is the disk size that we selected when we were creating the Virtual Machine.
This this size has shown up here is telling us we have 10 gig of this space.
How do you want to partition it.
We are telling it automatically configured the partitioning if you know or if your organization has
a requirement to partition a disk into different slices or different partitioning then you will go ahead
and click on i will configure partitioning.
Now go ahead and click on done
next one is K dump K dump is enabled.
If something goes wrong k means Colonel.
If there is something wrong with your system a colonel is going to write some messages and logs.
That is often referred in a Linux language as a dump that is enabled.
So it's always a good practice to leave that enabled.
So this way if you are troubleshooting with your vendor let's say if you have centaurs redhead involved
they could go ahead and take a look at your logs.
Next one we have is networking and hostname.
Okay you we are on a network and hostname configuration at the bottom you'll see hostname.
Go ahead and highlight what we have right now and hit delete and type in the hostname of the Linux operating
system.
Type the same one as we picked for our VM my first Linux VM and click on Apply as soon as you click
on Apply you'll see the current hostname was changed to the hostname that you have picked.
Now the second thing is to configure the ether net.
Now remember by default if you're machine or your washing machine.
This is your washing machine.
If it is running on a P.C. that has one gig often network port it will show up here as beat 1 gig.
And right now it is showing its why it for me because I have selected or I or my machine there I'm running
this washing machine is wired.
So go ahead and click on configure
and by default it will show up the tab as Ethan it e e and PS Your S3 is the name of our network adapter
so we'll click on general and we'll click automatically connect to this network when it is available
that the rest of the setting is blacked out.
By default you can leave as default IPTV free for setting is the setting for automatic DSP if you want
to assign an IP then you wouldn't have to change it to manual but we want the IP to be assigned automatically
so we will leave it as is.
And then the last one is IP 6 settings.
We don't use that right now.
So go ahead and click on save.
So once you click on Save you will see it tells you automatically connected it is given an IP already
and now you could go ahead and click on done.
OK.
And so our network and hostname has been configured now.
The last part a security profile no profile is selected you can leave that as is unless your organization
has a specific procedure to put it in place for security policies.
Then you could define it here.
But for now you could just leave as is and go ahead and click on begin installation.
Once you click on begin installation you will see at the bottom it will start creating your ID your
protections that were selected that you asked the system to selected for you.
Now it's going to starting package installation process.
While this is going through the packet installation we have to use the settings to define first as root
password.
So go ahead and click on root password is not set.
And here you would have to put in the root password.
Pick anything that you you will remember
if you notice I picked a vk password.
You should pick a strong password if you are if you're working for a company or if you are an organization.
But if you are just following my lab or you are doing this everything as a tutorial that is fine you
could pick a weak password.
However if you notice at the bottom it says the password you have provided it is weak the password fails
the directory check it is based on a direction dictionary word which you will have to press done twice
to confirm.
So OK I understand it is a weak password in order for me to keep that password I have to press it done
twice.
1 2.
Now it has taken that weak password user creation.
Let's go ahead and create our first user full name.
Let's put in our first name by default Linux takes the first name as the first letter.
First initial last name as complete last name.
So for me the user name will be.
I have Sol.
Keep your user name shorter than 32 characters and you do not use spaces.
That is fine.
We are not using any spaces we are only using 6 letters.
Make this use it administrator.
You can leave that out.
Requires a password to use this account.
Yes.
Let's pick a password again.
It is weak I understand.
I would have to do the same thing done twice
OK.
It is done now.
If you come down and you notice right here it the operating system is stalling or this Vizard is installing
packages for this operating system.
Total number of packages that are required to be installed are thirteen hundred and ninety seven.
You might have a little more or a little less but that's OK.
It depends.
And it changes over time what other packages are installed what are the dependencies are store.
So again if your packages do not match with my packages do not panic you are OK.
So now you'll see it is going through the packages installation at this point.
It is.
It has installed almost 400 packages and there are still about six or eight hundred packages that needs
to be installed.
And this process will take.
I would say somewhere between 10 minutes to 30 minutes I am going to fast forward this entire process
to save time.
Now the packages installation has been completed.
Now it is going to some post installation setup.
All right.
Finally our installation has been completed successfully now.
S.O.S is now successfully installed and ready for you to use.
Go ahead and reboot to start using it.
Click on reboot.
Well since the system comes back online it will give you the initial setup page the first page is about
licensing you have to accept the license click Accept license agreement click on done network and hostname
if you notice we have already selected this network and host named configuration.
During our installation so that you don't need to do it again click done and right here says finish
configuration.
Go ahead and click on finished configuration.
Finally our entire Linux installation has completed and now we have to log in the first time.
Click on your name or you could also log in as root a sheet.
If you remember you have picked a root password you would have to click on and not listed and type and
use an improved password.
But for now we will go in as ourself and we will put in a password.
Click on sign in or hit enter.
All right.
This is the desktop.
This is how it looks like in Santo.
It is very similar to Red Hat S.O.S.
You have these icons right here.
You can resize them if you want to.
You could delete any icons you could create icon and you could explore other things on the application
and spaces so.
Also one more thing when it starts up.
It also gave you this welcome page so you just leave as English.
Go ahead and click on Next.
Typing if you want to change anything you leave a default location services.
I usually keep it off if you want to leave it on.
It's really up to you.
Click Next connect to online accounts.
You don't have to do that.
Click Skip and then start using sent OS Linux.
So once again congratulations.
So now you know how to do the complete Linux S.O.S installation.
If you think that you missed something then I will recommend you to go ahead and delete this entire
Linux we m and go ahead and create a new washing machine and do the Linux installation again from scratch.
The more you do the more practice you will do the more you will learn.
All right.
Good luck.
