What to finish, look before learning Linux?

Question

linux

Good afternoon, I ran into a trace. problem: studied CCNA, went through parts 1-2, decided to move to Unix, looked at very basic things: creating users, rights, simple commands, inodes (superficially), etc.
I decided to move on to more practical things, found a couple of video tutorials: and I understand that I don’t understand anything,
why such a network topology, why this or that is needed, etc. I tried to watch the rise of Apache, nginx
(Interested by the web.) - the same thing. Advise what to look / read to close the gaps. In which direction to dig.
I will be grateful!

Answer 1

look

No need to look, raise the virtual machine and do everything yourself, plus google the specific problems or questions that have already arisen.

Answer 2

A two-week video course "how not to insert a USB flash drive into an Ethernet connector."
Necessarily. Don't touch anything without it!

Answer 3

why such a network topology, why do you need this or that

Okay, google.
Olifer and Olifer. Computer networks.

Answer 4

Well, for starters, if you want to get into Linux, you should look for how to install it. Somewhere. It's easier now than it was 15-20 years ago.
And after that, just google where you have already found holes, for example, network topology. Pretty primitive topic, if you enter. Especially as far as I remember at a tsiska with it everything is all right. About 10 years ago, + -, they even had a game that taught on this topic, googled it. maybe something has been preserved.
And the web ... It is enough to set a goal to set up a server on a local machine so that the site is launched on a local computer. And complicate this task. Yes, at least all sorts of dockers.
And in principle, if the graph-interface is on the side, then it may be enough for the WSL-ki.

Answer 5

Damn, well, you ask questions ... What to teach? - what do you need? What distribution will you use? For what purpose? From personal practice, I can give this advice: "First, study the disk layout. Find out what LVM is and how to work with it, don't forget about standard partitions, come up with different cases for yourself, like there is a VM with three disks that are collected in one Logical Volume , and what to do if one of the disks needs to be increased. And what to do if you need to add a 4th disk? And so on. The creation of a server begins with disk layout, and if you don’t know how to do it right, then you will suffer "
And so, lift a couple of wheelbarrows with different distributions, come up with a couple of cases for yourself and try to solve them yourself (with the help of Google and someone's mother)
