You can also have different urls for apps in one server configuration:

• yourdomain.com/app1/* -> to Node.js process running locally http://127.0.0.1:3000
• yourdomain.com/app2/* -> to Node.js process running locally http://127.0.0.1:4000

In /etc/nginx/sites-enabled/yourdomain:

server {
    listen 80;
    listen [::]:80;
    server_name yourdomain.com;

    location ^~ /app1/{
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass    http://127.0.0.1:3000/;
    }

    location ^~ /app2/{
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass    http://127.0.0.1:4000/;
    }
}

Restart nginx:

sudo service nginx restart

Starting applications.

node app1.js

var http = require('http');
http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello from app1!\n');
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');

node app2.js

var http = require('http');
http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello from app2!\n');
}).listen(4000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:4000/');
