Linux for net/sys admins question

[come on man]

hey guys, soon I'm gonna start my courses for sys and net administration  and yet I have 0 experience with Linux.Can you recommend me which distro to use at first?In my country the requirements in the jobs are mostly RedHat,Fedora,Debian.Should I start straight with them or it's better if I start with something easier like Ubuntu?I wonder if I should start learning linux even now before the course starts,but the thing which makes me think to postpone the learning of Linux is maybe I will have to learn how to troubleshoot systems on Windows and after that we are studying Linux

I started with ubuntu server. Once you know how to navigate through it, edit stuff or whatever that makes you comfortable navigating through it.

Debian is very similar so that change is quickly made.

 

Have no experience with fedora or red hat but i've tried centOS (which is afaik similar to redhat) which was easy to use but you just need to know what programs are available.

With ubuntu you have apt-get for updating and upgrading stuff, redhat uses yum. Different program, different syntax, but that's just a matter of reading documentation.

 

If you have time, try to go through this: https://www.linuxcertification.co.za/sites/default/files/linux-esentials-manual.pdf

yesterday my friend made a video how his arch linux boots for 2 seconds and he said it loads faster with systemd,because the loading is parallel.How to use that systemd?Or it's just implemented on particular distros?

TBH: I'd start learning the distro they will be teaching in the class.

Once you understand and are comfortable with that distro, changing distros will be a snap, because you understand the basics.

don't get into systemD vs init scripts, that's a rabbit hole you will never emerge from.

that makes sense,maybe you are right.why would you recommend to not get into systemd or init scritps?I thought by default ppl will always choose systemd over openrc,but I heard openrc is more stable.Anyways,maybe I'm wrong or it's just a too wide discussion for Linux newbies

(Linux admin here)

systemd is the antithesis of everything Linux stands for. Like I said, you don't want to go down that rabbit hole, at least not in a public forum. PM me if you want more however.

Yeah, we're not looking forward to porting our Linux configurations to systemd at work when we swap to CentOS 7

If you want to come as close to Redhat as possible you can use CentOS or Sientific linux (both of which are RHEL based. I really have no good answer for you as you seem to use most of them, so maybe testing all the things on all, or focus on the system you use the most in class?

The closest to Redhat is Fedora. Fedora is the community version of RHEL.

To the OP, I say load up a USB with different distro and play around in the them.  Get familiar with moving around in terminal and using text editors like vi and nano.  That way you have some familiarity with some of the distros.

Ubuntu or Debian is a good place to start, the only significant difference between Debian based and Redhat based distros is that the latter has it's important config files in /etc/sysconfig/ and it uses SELINUX instead of AppArmor, another difference is the logfiles but this is a minor thing.
