Both nginx and apache are webservers and can do what you need.
Apache calls this Name-based Virtual Hosts. (see ServerName/ServerAlias)
Nginx calls this Name-based virtual servers (see server_name in the docs)

Either will listen on ports 80/443 on the IP and proxy the request depending on the hostname used. If you’re not really familiar with either, I would recommend nginx. It’s very popular, the documentation is good and the syntax is a lot better IMO.

I hear caddy is also a nice alternative with even simpler syntax, but I haven’t used it myself.

Good luck!

I can see how you’re not yet familiar with all these terms :p Both nginx and apache are http servers and work the exact same in your case.

The server (apache or nginx) listens on the IP on port 80 and 443. Depending on the hostname that is used to connect, the request is proxied to a different location. Apache calls this virtual hosts, nginx call this virtual servers

Please correct me if I’m wrong, but here’s what I think the situation is:

• you have two different sevices that you have domains for, e.g. lemmy and bitwarden.
• you have two domains, lets call them lemmy.com and bitwarden.com .
• you have one (public?) IP address. let’s call that 123.123.123.123 .
• you want to use this IP address for both domains (e.g. bitwarden.alpha.com and lemmy.beta.com)

In that case you need both domains to connect to the same computer (because that’s the one with that IP address) which routes it to the correct location (either on the same computer or on a different one).

You basically have two solutions (that you already mentioned)

1. single machine

• You run both services on a single machine, listening on different ports on localhost/127.0.0.1 .
  • lemmy listens on port 1234 and bitwarden on port 8080.
• You use nginx (or caddy/apache) to listen on the web ports (80, 443) and reverse proxy(!) the content.
  • if the domain is lemmy.com it proxies from localhost:1234
  • if the domain is bitwarden.com it proxies from localhost:8080 This is the easiest solution IMO.

2. different machines.

This is essentially the same, but instead of the services running locally, one or both run on different machines.

• you run both services on different machines
  • lemmy on 10.0.0.10:1234
  • bitwarden on 10.0.0.20:8080
• You use nginx again as reverse-proxy(!):
  • if the domain is lemmy.com it proxies from 10.0.0.10:1234
  • if the domain is bitwarden.com it proxies from 10.0.0.20:8080
• be sure to check the firewall settings of the machines, that allow it.

In both cases the IP address points to the machine running nginx.

If you can run both services on the same machine with docker, you should just use this: https://github.com/nginx-proxy/nginx-proxy
