In the previous video, we already learn how to import cisco router to gns3, next in this 2
video, we are going to learn how to install ubuntu server. we will use the ubuntu server 3
to doing a network automation. 4
Let’s just start, 5
We will install the ubuntu server on virtual box, if you don’t have virtualbox yet, you 6
can download it first. 7
Just go to virtualbox.org, download, and here we can choose the operating system that you 8
use. 9
I will not show you how to install virtualbox, because this is very simple, 10
For now, I already have virtualbox installed on my laptop. 11
Next, we need to download the ubuntu server installer. 12
Go to releases.ubuntu.com/20.04, this is the latest version of ubuntu when this video created. 13
Here we can choose the server version. 14
I also already download this ubuntu installer. 15
Now let’s start learn how to install ubuntu server on virtualbox. 16
Click new here to create a new virtual machine, for the name, let’s say Ubuntu, continue, 17
I will leave the RAM as default, which is 1gig, 18
Continue, and here choose create to create new virtual hard drive. 19
Choose VDI, continue, dynamic, continue, here we can choose the size of the virtual hard 20
drive. 21
The default is 10gig, this is enough, so let’s just create. 22
And done. 23
Let’s start the virtual machine, when we start the virtual machine for the first time, 24
we will need to choose the installer, 25
Add, and then choose the ubuntu installer that we have downloaded before. 26
Start, 27
Okay now we can install the ubuntu server, choose the language, you can use up and down 28
arrow in the keyboard, and to go to the next step, you can use enter. 29
Here I choose English and then enter, 30
Here we have a question about ubuntu update, I choose continue without updating here, and 31
then enter, 32
Here we can choose the keyboard type that we use, this is the right keyboard for me, 33
so just enter, 34
Here we can configure the ip address, but the default is dhcp, for now we will leave 35
it as default. 36
Proxy address, leave it blank, done, 37
Mirror address, leave it default, done, 38
Here we can choose the partition method, the default is automatic partition, if you want 39
to doing a partition by your self, you can choose custom storage layout. 40
If you beginner, just leave it default and done. 41
We can use tab in the keyboard to go to done, and then enter. 42
Here we need to type the username and password, 43
To move from username to the password you can use tab, 44
Here we have a choices to install ssh server or no, in this case I will install ssh server. 45
so we can remote the virtual machine from our laptop. 46
Let’s check this using space in the keyboard. 47
Here we can choose some application. 48
But I will leave it as default. 49
Okay now the installation process is running. 50
We just need to wait until the installation process is done. 51
Okay now the installation is done, we can see installation complete here, but in the 52
buttom, we can see downloading and installing security update, you can wait until the update 53
is done, but for now, I will just cancel the update and reboot. 54
Okay here the ubuntu is ready, let’s login using username and password that we have created. 55
Okay we are success login to the ubuntu server. 56
I think enough for this video, in the next video, we are going to learn how to connecting 57
this ubuntu server with router inside gns3. 58
Thank you for watching and see you on the next video.
