There is literally no instructional guide on how to set up bitcoind on a server. I've tried for around 30 minutes now and I have no idea what I'm doing.

So far I installed the package.

and every single command other than "bitcoind -?" just returns with "bitcoind can not obtain a lock of data entry" "bitcoin is probably already running"

I understand that bicoin is running, but how do I know what is it doing? How do I set this up? What does this even do? Does it send funds or does it create its own wallet? What is going on?

Can anyone help me?

Thanks in advance!
