Hi there and thank for making this community,

My name is Peter and i am an indie game developer and i need a little help to setup 3 domains on a hostinger vps.
I had a little experience in the past with mybb board and web design but i don't have enough experience to find my way on an unmanaged vps.

I have done my home work and read a lot and i am getting more comfortable but just need to understand some basic concepts.

I do all my setup under unbuntu 20.04 on console command and so far i have install unbuntu 20.04 and made myself a user and setup ssl with putty,install nginx, setup firewall etc.

What i basically need to know is what is the folder structure for hosting 3 domains on one vps? Do i need to make all 3 folders in the root directory or in 3 separate folders in nginx directory? I also want these 3 domains to be under same ssl if possible.
Precision, the 3 domains are not sub domains,the fisrt one is www.mygame.online, the second www.gamevlog.online and the last www.gamesupport.online.

Thank for any help i can get since as an indie game dev i cannot afford to hire a specialist for the moment.

Regards Peter
