What is the order in which to learn the skills of a system administrator?

Question

System administration

Good evening.
Not so long ago, I started reading a lot of books on Linux and FreeBSD administration, which actually led me to the desire to become a system administrator (And that article on Habrahabr did not scare me at all, but only fueled my interest). A good friend of mine tried to help me by making a list of basic skills for a system administrator. Such lists are found everywhere, and all have only one problem. In what order? What kind of books to start with and what skills do you need to master first? I hope that for a question with such a vague wording, I will find an answer to it, not without outside help. Thanks in advance.

Answer 1

Try to build a tyrnet access server on Linux or FreeBSD. Full-fledged, with routing, with a firewall, with a proxy, NAT, connecting to AD and authentication of proxy users in it with access control by groups, with mail, a local web server. And for IPTV to work, if you have it, of course. And try to do it without any iRedMail-s, but with handles, from the console with text configs - here, everywhere and everywhere, as a result, text configs. It's not easy and not fast :) For a snack, you can set up a VPN with a neighbor with authentication using certificates that you issue yourself - to yourself and your neighbor :) When all this works for you, you yourself will give advice here :)

Answer 2

for literature, Evie Nemeth would recommend "System Administrator's Guide"
RHCSA / RHCE Red Hat Linux Certification Study Guide

Answer 3

IMHO, start doing.
As soon as you come across something you don't understand, read the literature. Start by manually installing Apache+MySQL+PHP on the virtual machine.

Answer 4

CityCat4 described everything correctly and after such practical skills, you can definitely give advice here)) But it scares you a little, because you don’t know what to grab onto ..
But if you are new to Linux, it would be nice to start from the basics. And most importantly, make a virtual machine with classic Ubuntu and try to complete tasks.
That's how I started and continue to study.
At the initial stage, watch a worthy video course by Kirill Semaev LPIC1,2 (there is even a DZ)
After all, try to choose the simplest task for implementation. In my opinion, this is a file server, then complicate it and bring it into a domain.
Further, when the information is in your head to meet what's what, start the checklist from CityCat4. Although after that you yourself must decide what is more of a priority for you.
In my case, it was easier with such a scheme, but again, I repeat without practice and a working virtual machine, without the practice of typing commands, everything is somehow not remembered.
PS Google thematic articles, browsing the habr on the subject.
Good luck with your study!
