How to install Discourse on Apache server with existing site

Hi, I have a Wordpress site on my server and I need to install Discourse. I followed this guide but it assumes I have a running instance of Discourse, which I do not have. I tried google, but I keep coming up with the same error every time I run ./discourse-setup

This is the output:

Port 80 appears to already be in use.

This will show you what command is using port 80
apache2 16511 root 4u IPv6 123057 0t0 TCP *:http (LISTEN)
apache2 16514 www-data 4u IPv6 123057 0t0 TCP *:http (LISTEN)
apache2 16515 www-data 4u IPv6 123057 0t0 TCP *:http (LISTEN)
apache2 16516 www-data 4u IPv6 123057 0t0 TCP *:http (LISTEN)
apache2 16517 www-data 4u IPv6 123057 0t0 TCP *:http (LISTEN)
apache2 16518 www-data 4u IPv6 123057 0t0 TCP *:http (LISTEN)
apache2 16550 www-data 4u IPv6 123057 0t0 TCP *:http (LISTEN)

Any ideas?

You will need to edit the app.yml file by hand to install on a different port.

I don’t have one since I can’t start the installation. Should I make one, and if so, what should it look like?

Discourse-setup created it. It’s in the containers directory.

It didn’t.

root@LoadScreen:/var/discourse/containers# ls
root@LoadScreen:/var/discourse/containers# ls -a
. … .gitkeep

So true;sorry about that. The guide you linked to describes how to create it. Or you can quit apache and then run discourse-setup.

A good first step would be to turn off apache and get discourse working, then try to make the changes to have apache reverse proxy.

Doing it, thanks! What would be the next steps? What specific changes should I make?

While we’re at it, I’d like to make one suggestion though, prefer moving to Nginx instead of Apache 2 as it is known to cause issues with discourse.

For that matter, for a low volume site, it’s easier to have 2 1GB droplets than a single 2GB droplet. A single 1GB droplet won’t have enough RAM. If you already have a server with 4GB or more, it might make sense. For most people, the only compelling reason to have both on the same server is if you want to do a subfolder install.

I was experimenting with installing Discourse alongside Apache, but after a while I gave up as this was a challenge way above my skill level, and to prevent breaking anything more than I’d already broken, I decided it was a much better idea to setup a separate droplet for my forum, both to release pressure on my other server, and for a simpler management.

I believe that’s possible with proxies, or am I completely lost now?

Thank you all for your help.

And @nicrats that’s exactly how I feel and I think that’s what I might end up doing.
