Setting Up A High-Availability Load Balancer With HAProxy/Heartbeat On Fedora 8

Post date: March 2, 2008, 12:03 Category: Installing Views: 4107 Comments
Tutorial quote: This document describes how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Fedora 8. The load balancer acts between the user and two (or more) Apache web servers that hold the same content. The load balancer passes the requests to the web servers and it also checks their health. If one of them is down, all requests will automatically be redirected to the remaining web server(s). In addition to that, the two load balancer nodes monitor each other using heartbeat. If the master fails, the slave becomes the master - users will not notice any disruption of the service. HAProxy is session-aware - you can use it with any web application that makes use of sessions like forums, shopping carts, etc.

High-Availability Load Balancer With HAProxy/Keepalived On Debian Lenny

Post date: June 16, 2009, 10:06 Category: Installing Views: 4530 Comments
Tutorial quote: This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and keepalived 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 keepalived, 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.).
