How to Install, setup and config HAProxy loadbalancer for content switching

First here is the guide I have written to install and configure HAproxy. Next, Sometimes we have different servers with different contents, such as one set of servers with all static contents (html, image files) of a website while another set of servers have dynamic contents (cgi, perl, php scripts) This type of config is beneficial in some situations where you want to serve your static data directly from CDN for faster response and dynamic contents from your own servers.

Download, install and configure perlbal to load balance web server

Perlbal is fast and efficient web server, reverse proxy(load balancer). Here are quick steps to get started with it. I have tested perlbal-1.60 on my CentOS 5 box. There are many other possible ways to do the same and the way which worked for me, may not work for you.

Step 1. Download perlbal OR install it via perl cpan, like this:

$ perl -MCPAN -e shell
cpan-> install perlbal

Step 2. Find out its sample config (/root/.cpan/build/Perlbal-1.60/doc/config-guide.txt) or if you downloaded and compiled it, file will be there. Put this file in /etc/perlbal as perlbal.conf.

$ mkdir /etc/perlbal
$ cp /root/.cpan/build/Perlbal-1.60/doc/config-guide.txt /etc/perlbal/perlbal.conf
