VestaCP - control panel on a subdomain, how to do it?

Question

System administration

Hello.
I have such a puzzle. I want to configure the control panel in such a way that it opens only at panel.domian.ru. And no other way.
I saw an article detailing the process on how to do this, but it doesn't work on my OS or cp.
OS: Ubuntu 15.04
Vesta 0.9.8-17 Thank you
very much.

Answer 1

nginx proxy pass will help you. You need to reconfigure nginx vesta so that it only listens on ip 127.0.0.1. And the subdomain already has a proxy pass.
