How to host 3 node applications with 3 different domains on one VPS?

Question

I'm stuck trying to set up multiple Node apps on different domains on the same Digital Ocean camera. I followed Host Multiple Node.js Applications on the same VPS with nginx, forever and crontab exactly.

I have all the correct pointers and a set of records.

I can not force applications to run (from forever) on any port other than the standard express 3000.

I changed the Nginx settings as he asked:

I uncommented server_names_hash_bucket_size 64; (as they say)

I created the /etc/nginx/conf.d/example.com.conf files for applications (these are different domains, I put 1 on port 3000 and the other on 4000).

Example:

server {
listen 80;

server_name your-domain.com;

location / {
    proxy_pass http://localhost:{YOUR_PORT};
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}

}

, Nginx ? "npm start"? ?

});
