What to read on the theory of system administration?

Question

linux

Hello!
Recently, I immediately asked about courses on system administration ...
Right now I decided that it was useless to take courses without knowing the basics.
So I'm asking: write a list of topics to study, and if you can read good books on these topics... For example, on networks, setting them up, etc...
And so that the books are not very abstruse, I'm like 15 years old :)

Answer 1

There is no theory of network administration.
Only practice.
But about the theory of networks - an excellent series
of Networks for the little ones

Answer 2

1. Bormotov. System administration at 100%.
2. Vatamanyuk. Creation, maintenance and administration of networks.
3. Braginsky, etc. Network administration with examples.
4. Olifer. Computer networks.
This is for starters.
Practice by practice, but nobody canceled the theory.
And you can practice on virtual machines, as written above.

Answer 3

You are suffering bullshit. Take it and do it! Start the virtual machine and try. In which case, on a virtual machine, you can roll back or reinstall the system from scratch painlessly.

Answer 4

You first decide why you need it?
Possible options:
1. Just be smart or do something to be proud of.
2. I'm going to enter a university in the IT direction - I want to become DevOps. And I need knowledge now so that I can pass everything automatically and work in my second year.
<other options>
Depending on the options and strategies are different.
