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.

This document describes how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Fedora 8.

This tutorial shows how to set up a two-node Apache web server cluster that provides high-availability. In front of the Apache cluster we create a load balancer that splits up incoming requests between the two Apache nodes. Because we do not want the load balancer to become another "Single Point Of Failure", we must provide high-availability for the load balancer, too.

I know this topic is somewhat advanced for some of you, but for others hopefully this will be useful. So what is a load balancer? To better understand the term, let me explain to you a bit the meaning of load balancing.

This tutorial was written for the Debian Lenny distribution and supposes that the user has knowledge about what load balancing is and some basic skills of Linux, our two load balancers consist out of 2 machines that monitor each other [heartbeat], if the master stops responding the secondary one [Backup] will take the master role [Backup -> Master].

In this article I will describe how you can monitor your Debian Lenny server with munin and monit.

This tutorial shows how to set up a high-availability storage with two storage servers (Debian Lenny) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Debian Lenny as well) will be able to access the storage as if it was a local filesystem.

Cherokee is a very fast, flexible and easy to configure Web Server. It supports the widespread technologies nowadays: FastCGI, SCGI, PHP, CGI, TLS and SSL encrypted connections, virtual hosts, authentication, on the fly encoding, load balancing, Apache compatible log files, and much more.

Debian Etch is soon to be unsupported by the Debian team, therefore all Debian Linux Servers need to be upgraded to Debian Lenny. I have upgraded many Linux servers to Debian Lenny over the past months, so I am providing this guide on how to upgrade Debian Etch to Debian Lenny.
