Multiple NodeJS Instances under same domain/SSL

Description:
I have an application that ran on AWS LightSail which ran fine with SSL on port 4000 when it was a single NodeJS application. The application has now been split between into three separate NodeJS applications, UI, API and Chat. How can I set things up to allow access to all three nodeJS applications, all using the same SSL certificate? Ports are 4000,40001 and 4002. Thanks. Colin

Hi @colboy,

Thanks for using Bitnami. Can you give us more information about what do you want to achieve? Do they need to be publicly available all of them using Apache or do you need them to be interconnected internally and only the UI application to be reachable from Apache?

We have a guide about how to install your custom Node.js application and how to serve it through Apache. Can you check it?

All three services are interrelated and need public access. So the UI is the main app. The API is for communication with the database and the ChatServer is for peer to peer chat communication. An earlier version of this, had everything in one NodeJS application and it worked find, serving on port 4000, via Apache, with the port being forwarded via 80.

So in essence, Port 80 redirects to 4000, but 4001 and 4002, still go to their respective paths, so all three fall under the SSL certificate.

A fall back would be to just allow access to 4000, 4001 and 4002 without the port 80 redirect, which would require the user to enter https://mydomain.com:4000 to visit the site, if that's easier to set up.

Hi @colboy,

There are different ways of doing this:

You can access all the applications using Apache and the certificates it has. To do so, I understand you already configured a ProxyPass / to access the first app in the Apache's configuration, right? You can add new "ProxyPass" lines to access the other apps and restart Apache later

  ProxyPass / http://localhost:4000/
  ProxyPassReverse / http://localhost:4000/
  ProxyPass /myapp http://localhost:4001/
  ProxyPassReverse /myapp http://localhost:4001/
  ProxyPass /myotherapp http://localhost:4002/
  ProxyPassReverse /myotherapp http://localhost:4002/

You can also create new virtual hosts under the "/opt/bitnami/apache/conf/vhosts/" folder to configure different subdomains
- yourdomain.com will use the virtual host that redirects to the first app
- myapp.yourdomain.com will be another virtual host that redirects to the second app
- ...
If you want to use https and the app's port to access the app, you will need to configure the SSL certificate in your app itself so the server that runs in the port 4001 is able to use https with the certificates you configured.
