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-http_ssl_module --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;
}
