I have followed the steps here:

If you want to run other websites on the same machine as Discourse, you need to set up an extra NGINX or HAProxy proxy in front of the Docker container. NOTE: This is for advanced admins This guide assumes you already have Discourse working - if you don’t, it may be hard to tell whether or not the configuration is working. You cannot use ./discourse-setup to set up Discourse if another server is using port 80 or 443. You will…

and considered the steps here (but didn’t follow fully):  
[https://meta.discourse.org/t/run-discourse-with-or-alongside-existing-apache-sites/19514](https://meta.discourse.org/t/run-discourse-with-or-alongside-existing-apache-sites/19514)

When I run `/var/discourse/launcher enter app` I get:

`which: no docker.io in (/sbin:/bin:/usr/sbin:/usr/bin:/opt/aws/bin)`

When I run `service nginx restart`

```
[root@ip-xxx.xxx.xxx.xxx ec2-user]# service nginx restart

```

I guess that because port 80 is taken by httpd to serve the currently running Wordpress site.

This is the config in my nginx.conf, this is likely the setting when I was trying to configure to use nginx for the Wordpress site. /var/www/phagerx/htdocs is where the Wordpress installation resides. Shall I change it to point to /var/discourse?

```

```

This is my app.yml:

```
templates:
  - "templates/cron.template.yml"
  - "templates/postgres.template.yml"
  - "templates/redis.template.yml"
  - "templates/sshd.template.yml"
  - "templates/web.template.yml"
  - "templates/web.ratelimited.template.yml"
  - "templates/web.socketed.template.yml"
## Uncomment these two lines if you wish to add Lets Encrypt (https)
  #- "templates/web.ssl.template.yml"
  #- "templates/web.letsencrypt.ssl.template.yml"

## which TCP/IP ports should this container expose?
## If you want Discourse to share a port with another webserver like Apache or nginx,
## see https://meta.discourse.org/t/17247 for details
expose:
  #- "80:80" # http
  #- "443:443" # https

```

This is my discourse.conf:

```
server {
	listen 80; listen [::]:80;
	#listen [::]:80 ipv6only=on default_server;
	server_name ask.phagerx.com; # <-- change this

	location / {
		proxy_pass http://unix:/var/discourse/shared/standalone/nginx.http.sock:;
		proxy_set_header Host $http_host;
		proxy_http_version 1.1;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_set_header X-Forwarded-Proto $scheme;
	}
}

```

[ask.phagerx.com](http://ask.phagerx.com) is intended to be the Discourse forum and [phagerx.com](http://phagerx.com) is the existing Wordpress site working on httpd.

Would appreciate if you can shed some light on the part that I’ve been missing. I have added a new custom port 101 in my AWS security for Discourse traffic to be routed to if necessary. But I haven’t added this new port in all my Discourse config yet.
