Debian High-Availability Load Balancer With HAProxy/Heartbeat On Debian Lenny
Post date: July 14, 2009, 09:07 Category: Views: 2522 Comments: 1
Tutorial quote: This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Debian Lenny. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content. Not only does the load balancer distribute the requests to the two backend Apache servers, it also checks the health of the backend servers. If one of them is down, all requests will automatically be redirected to the remaining backend server. In addition to that, the two load balancer nodes monitor each other using heartbeat, and if the master fails, the slave becomes the master, which means the users will not notice any disruption of the service. HAProxy is session-aware, which means you can use it with any web application that makes use of sessions (such as forums, shopping carts, etc.).

On the subject of load balancing, why not get the highest availability while not getting caught in high prices? Kempís got some great load balancers that are low priced and high in quality: http://www.kemptechnologies.com/?utm_source=blog&utm_medium=pv&utm_content=zs&utm_campaign=home
