today I have searched very long to discover if my bitcoin.conf settings are wrong, and I found some mistakes there.
After some fixes I could run commands from my Bitcoin server's command line and it works.

Now the problem is that I still can't use my rpc.

I'm sorry for this, but I just want to know if it's required to install some server like ( Apache, nginx... ) in the Bitcoin server side?
Because I'm new in this kind of stuff and have to learn many things.
