Installing Our First Linux Virtual Machine for Learning Systems Administration

So explain to me why you skipped turning on networking in the GUI?
In my experience with novice users, you avoid an entire host of issues if you additionally setup networking on that installation screen.
It is not like the desired networking information will change between the GUI install and time you first login.

ready for the next class -
Centos 7 installed in HyperV server W2008r2.

Good point, I'm modifying it now.

I do realize, that it is not hard to setup networking in CentOS, but if your target is novice users, I think enabling networking in the GUI is the best thing to do. Because then you can drop straight to SSH next.

Got it redone with the updated screen shots and details.

Ready & waiting for lesson # 2: Linux: The Lay of the Land, Filesystem Herarchy

Thanks, SAM! I had my VM installed and ready last night.

One other thing that trips people up is it doesn't enable the NIC by default. If you don't configure it and enable autloading, there is no networking until you configure the ifcfg file.

That is what I just said. Turn it on in the GUI during initial config.

Wow, I don't know why I did that. It's been a long day.

It is partially written and open on my desktop (I write in Atom then post over to keep my browser from crashing and losing it.) Hopefully later today.

If anyone has specific topic ideas, feel free to share. I have covered this material for decades but have never taught someone from the ground up and so am trying to figure out how to teach, and cover, the basic stuff both for a beginner and for someone coming from a Windows Admin background and not have huge gaps making things hard to understand.

@scottalanmiller Logging in using SSH with public/private keypairs instead of username/password to increase security might be a good topic or subtopic. Enjoying what has been posted so far!

That's definitely coming. SSH and key management will be major topics.

Something that I'd like a better grasp on is how the mindset is different. Coming from a decade+ of Windows admin work, some of the things that others call easy, or assume that it should be understood, I don't get. There are many examples, but today I ran across an irritating one: installing RAID drivers. In Windows, this is either easy, or undoable. In Linux (during install) it appears to require a significant background. "Just compile from source." is not an easy answer for me at this point because I don't even know where on my mental grid to fit that, much less how to do it for the variety of needed scenarios.

Wait. What? You shouldn't really be installing RAID drivers at least not to my knowledge. As far as the OS is concerned that is just raw disk right?
