Jitsi Server Installation Configuration

I have an ubuntu 18.04 web server with my website working on apache2 with PHP.
I also have an rtmp server on nginx there.

I wanted to install Jitsi Server there. Is it possible that my hostname is infocom and website running is fsg,in . Now can I install jitsi on subdomain videocon.fsg.in. Do I need to change hostname to videocon.fsg.in or can it continue with infocom.

Finally I want to have jitsi running on videocon.fsg.in

Request your suggestions.
