How to setup load balancing on multiple websites with only 1 Public IP address available using HAProxy.

Some may wonder how you can host multiple websites on multiple servers when you only have 1 public ip address available it is simple.

We will first need to have linux setup and  configuired.  I have used Centos 5.4 in my example.

 

global
maxconn 4096
pidfile /var/run/haproxy.pid
daemon
nbproc 2 # Number of processing cores. Dual Dual-core Opteron is 4 cores for example.

defaults
mode http
balance roundrobin
cookie SERVERID insert indirect
stats enable
option forwardfor    
retries 3
option redispatch
maxconn 20000
contimeout 50000
timeout client 500000
timeout server 500000
