如何从 apache2 VPS 在子域上托管 Node.js 应用程序？

Question

So, I have a Node.js app and I want to host it on a subdomain using my VPS. My VPS is currently running apache2 and my Node.js app uses Express. I have tried Phusion and have also tried this tutorial with no luck. Also, my app uses Puppeteer which I'm not sure it makes a difference. I'm new to servers and web development so any help would be greatly appreciated. Thank you.

You can host the production-grade application with the help of Nginx & PM2 (node process manager) Instead of apache, you can give a try to Nginx since most of the NodeJS or Express application use NGINX as an HTTP proxy front of PM2. You need to do reverse proxy of your domain to localhost:<port>

Sample Nginx vhost,

server {
   server_name application.com;
   location / {
       proxy_pass http://<private-ip>:<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;
   }
}

For setting up PM2 . Install this process manager globally. For more reference you can check it here
