Nginx Upstream Fair Proxy Load Balancer

Description:

The Nginx fair proxy balancer enhances the standard round-robin load balancer provided with Nginx so that it will track busy back end servers (e.g. Thin, Ebb, Mongrel) and balance the load to non-busy server processes.

Further information can be found on http://nginx.localdomain.pl/

Ezra Zygmuntowicz has a good writeup of the fair proxy load balancer and how to use it here: http://brainspl.at/articles/2007/11/09/a-fair-proxy-balancer-for-nginx-and-mongrel

Installation:

You'll need to re-compile Nginx from source to include this module. Modify your compile of Nginx by adding the following directive (modified to suit your path of course):

./configure --with-httpsslmodule --add-module=/absolute/path/to/nginx-upstream-fair make make install

Usage:

Change your Nginx config file's upstream block to include the 'fair' directive:

upstream mongrel { fair; server 127.0.0.1:5000; server 127.0.0.1:5001; server 127.0.0.1:5002; }
