Hi, everybody! I’m trying to install discourse on a subdomain. My main domain is running wordpress, which was built using docker-compose. The subdomain and the domain are using the same VPS server. For the installation I followed this guide: https://meta.discourse.org/t/run-other-websites-on-the…

Did you change the ports in the app.yml so that Discourse isn’t trying to use the ports that NGINX wants? [image] Daniel Jurnik: Sorry, I’m a beginner with Linux / NGINX / Docker things. Any advice would be appreciated. Thank you. This is an advanced setup that requires understanding of DNS,…

As I mentioned, wordpress is running on the main domain. If I understood correctly, the other NGIX works in the container together with wordpress. I followed this tutorial: How To Install WordPress With Docker Compose | DigitalOcean If I run the netstat -tulnp command, this is what I get: Active…

As I stated, I believe the other NGIX (the one for wordpress) works in a container together with MySQL, and Wordpress. This is what I get by running docker ps command: CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS …

That would be why the external nginx cannot boot, as the ports are taken by the internal one. You probably need to shut that container down and transfer it’s config for Wordpress to the outer nginx layer. Also, those are separate containers, the nginx is separate from MySQL and WordPress.

I shut down the webserver (NGIX container) and tried to start the external NGIX. Still not working. [image] Firepup Sixfifty: Also, those are separate containers, the nginx is separate from MySQL and WordPress. You’re right. It’s my fault. I thought all the apps mentioned were in one contain…

Did you change the ports in the app.yml so that Discourse isn’t trying to use the ports that NGINX wants?

This is an advanced setup that requires understanding of DNS, https and certificates, nginx, reverse proxies, docker, and routing.
