Issue installing Discourse on OVH VPS Ubuntu 22.04

Installation
42

Only true if it’s being managed by systemd, which isn’t always the case. I’ve seen too many instances where some random package installs it, disables the service, and then starts and stops it as needed.

I’ve also seen at least one package in the past that installed a .service file for it even though nginx wasn’t actually installed.

The both of those will happily tell you the status is disabled. The apt method guarantees that if it is actually installed you’ll know unless it was compiled from source, and we probably wouldn’t be having this conversation if that was the case. :slight_smile:

Hello @Claudia Thanks for your help.

Hello @Jagster

When I do systemctl status ngin
The result is : Unit nginx.service could not be found.

You’ve definitely got the full nginx installed. I also see some web applications listed that require it, like Kopano.

Does someone else have access to your VPS?

@xiaokong23357 I did this in app.yml file
expose:

  • “80:80” # http
  • “9090:80” # http" ensures that nginx can be proxed to discourse
  • “443:443” # https

After I did ./launcher rebuild app

Always the same message on the browser :

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

For online documentation and support please refer to nginx.org.
Commercial support is available at nginx.com.

Thank you for using nginx.

@Claudia
No only me and the provider OVH of the VPS

48

If I’ve a full ngix installed why when I do systemctl status ngin
The result is : Unit nginx.service could not be found.

Or it’s installed but not running.

You can delete port 80 without using it to prevent conflicts between discourse and nginx

You don’t have Nginx working as reverse proxy. Plus now you are redirecting two ports as 80. You must have either one, not both. And because you aren’t using Nginx, and because of that you don’t have virtual host proxying to port 9090 or any other port you must comment out that.

Do you have anything else installed via docker? Because now it sounds a bit like your Nginx in docker works but Discourse itself is down.

That was a fresh install, right? I would discard whole VPS and start over.

I would spin up a new vm and start over, but in any case, you can try to remove nginx.

apt remove nginx

You need to leave discourse with access to port 80.

It is a good bet that you have hit let’s encrypt rate limits. You’ll likely need to use a different subdomain or wait a week.

Hello
I didn’t find the solution so I decided to change hosting provider.
Thanks to all for the support.
