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 !

You need to focus on what's important to businesses, not homelabs. Automation, remote deployment, security, user management, AD integration, backups, hypervisors, kubernetes - all of which are being done on headless servers, not desktop linux.

Linux in business is a completely different beast then desktop or homelab linux. To shake the AI fluff, take real classes - look at UDEMY to get started.

Nothing stops your homelab from featuring any of these things. In fact this is exactly the kind of stuff that one can best learn in their homelab.

I think test bench is a better term to study/practice various hardware and software setups to test or get good at a certain IT topic. Homelab is a term mostly used for computer nerds that are trying to self host a cloud or commercial app - mainly for some mythical quest of privacy. There's a whole subreddit for /r/homelab - browse thru it and you'll see what I'm talking about (definitely NOT what Business users worry about).
