Hi there @selll,

I would recommend following the steps from this tutorial here instead:

https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-16-04#set-up-nginx-as-a-reverse-proxy-server

Then once you want to start a second Node.js application keep the following things in mind:

• Make sure that you use a different port for each application
• Make a copy of the /etc/nginx/sites-available/default to /etc/nginx/sites-available/example2.conf and adjust the values there to match your second application
• Then enable the second site:

ln -s /etc/nginx/sites-available/example2.conf /etc/nginx/sites-example/example2.conf

Finally, restart Nginx as explained in the tutorial.

Let me know how it goes.
Regards,
Bobby
