Public and private SSH keys and connections aren’t hard when you grok how SSL/TLS works. Encryption in general is good to have a handle on conceptually, I’d recommend picking up and reading a short introduction on the basics.
Copying, listing, renaming, or unlinking files is usually embedded in your shell of choice itself. As the the shell is the way you call and run programs, you can’t know it enough.
The GUI of whatever desktop you’re used to using is effectively a shell itself, and has the same function: copy, list, rename, remove files and run programs. The difference is, instead of executing a command as you would on the CLI (i.e., entering the path to the file binary and hitting “enter”), you click on an icon representing the same file.
man
,find
,grep
,ssh
,chmod
, andchown
. Then your editors:vi
,emacs
, orjoe
.nano
is easy to use, but a little skill with a more advanced editor goes a long way.ping
,netstat
,host
, andtcpdump
.When you get all that, Ansible is nothing; it’s a way to systematically SSH into machines based on a local inventory and run a set of commands or scripts on all of them.
Never learned puppet, but it’s just one alternative to Ansible which looks to achieve the same thing: treating a set of hosts like they’re numbered cattle instead of carefully named and spoiled pets.
Edit: I suppose you can PM me your questions, if you want. Trying to write out and explain things helps me understand them better.
