Hey i trying to install Discource on my V-Server but my Problem is Port 80 is busy.  
And if i try to run the installer it stops

```
Port 80 appears to already be in use.

This will show you what command is using port 80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
apache2 6045 root 4u IPv6 573533480 0t0 TCP *:http (LISTEN)
apache2 6050 www-data 4u IPv6 573533480 0t0 TCP *:http (LISTEN)
apache2 6051 www-data 4u IPv6 573533480 0t0 TCP *:http (LISTEN)
apache2 6052 www-data 4u IPv6 573533480 0t0 TCP *:http (LISTEN)
apache2 6053 www-data 4u IPv6 573533480 0t0 TCP *:http (LISTEN)
apache2 6054 www-data 4u IPv6 573533480 0t0 TCP *:http (LISTEN)
apache2 6055 www-data 4u IPv6 573533480 0t0 TCP *:http (LISTEN)
apache2 6619 www-data 4u IPv6 573533480 0t0 TCP *:http (LISTEN)

If you are trying to run Discourse simultaneously with another web
server like Apache or nginx, you will need to bind to a different port

See https://meta.discourse.org/t/17247

If you are reconfiguring an already-configured Discourse, use

./launcher stop app

to stop Discourse before you reconfigure it and try again.

```

And i dont have a app.yml to Change the Port

Sorry for my bad English i come from Germany

Discourse requires ports 80 and 443. It cannot be run on a nonstandard port.

You will need to disable or remove Apache to use `./discourse-setup`.

If you want a reverse proxy in front, you can see [How to set up Discourse on a server with existing Apache sites](https://meta.discourse.org/t/how-to-set-up-discourse-on-a-server-with-existing-apache-sites/30013), but it requires a pretty good understanding of Apache and what reverse proxies are (and maybe English!). Oh, or the URL in the message that you include above.

You can copy `samples/standalone.yml` to `containers/app.yml`.
