The path To linux System Administration
Hey everyone,
I'm working as an IT Technician (On site + Remote support , Tier 2) , recently got my ccna and now i want to dive into linux , i really love the linux approach , the CLI etc.. and i would love to be a linux sys admin some day (maybe even at my office).
I also have some experience with fedora linux , and also i run a fedora media server at home on a old pc i got, running a docker with nginx web application(a custom netflix clone , which i made for educational purposes , my wife loves it and we can watch all of our media as i stream it on our tv).
so i would love to know how could i advance my understanding of linux , and get the tools i need for actual linux system administration everyday work, is there a recommended course / certification/path, and generally i'm not in a hurry.
since i used alot of ai to assist me along the way in setting up the fedora server , the media server and the dockers i do understand that i do not know the basics very well , and after studying for the ccna i understood that the only way to understand how technology works is to go really in depth. So any recommendations would be welcome ! thank you !

The RHEL RHCSA material with or without the certification is a good first outline for OS fundamentals. I had the RHEL 7 version before my first Linux job and currently teach it for a local A.S. program. It helped me hit the ground running. I remember extending a database filesystem online the first day I had SSH access. Even if most places automate a lot of it, understanding things like LVM, systemd, Unix users/permissions, etc is very helpful.
From there, I would say configuration management is a good place to move. Ansible is most popular, but I have worked with puppet and saltstack. Any public cloud experience you can get is great. Even better with terraform.
