Close but no. To reiterate, I’m on Linux + Ubuntu 18.04. I’m using Apache to serve up a standard HTML website (WordPress in the future) and have Discourse installed under a subdomain. I just need to figure out how to set up a reverse proxy (per these tutorials) that will redirect traffic from ports 80 and 443 to new ports since Apache uses both of those ports already. I’m not interested in using Nginx because I have no experience with it and don’t want to bundle it with Apache and make my setup even more complex.
I’m not an advanced developer. I’m just a guy with a fluent understanding of the frontend, basic understanding of panels, limited understanding of SSH, and basically no understanding of everything else (which is why I’m using tutorials).
My end goal is to have two domains with a respective frontpage and with multiple instances of Discourse (one for each website). Simple stuff.
