Nginx Load Balancer Example Setup and Config

Need to setup an Nginx load balancer and reverse proxy? This simple example will show you not only how to configure Nginx to balance requests across Tomcat, Apache, Express or Node based backend servers, but it will also show you how to weight servers in Nginx and even set up stick session for Nginx.

And what's amazing is how simple it all is. Just add an upstream entry, list your servers, set a weighting and then add the proxy_pass element and you'll have yourself an Nginx load balancer and reverse proxy.

This Nginx load balancer example does use Apache Tomcat as the backend server, but the Nginx configuration and setup is completely agnostic to where the requests get sprayed.
