How To Set Up A Loadbalanced High-Availability Apache Cluster Based On Ubuntu 8.04 LTS. Please note that my main reference and source is Falko's article here just modified for Ubuntu 8.04 LTS. Also some parts were taken from Falko's article "The Perfect Server - Ubuntu 8.04 LTS" here. Version 1.0 Author: Mohamed Ghaleb <Mohamed_Ghaleb [at] msn [dot] com> (English and German only please) Last edited 06/03/2008 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. Therefore our load balancer will in fact consist out of two load balancer nodes that monitor each other using heartbeat, and if one load balancer fails, the other takes over silently.

I will use the following setup here: I want to say first that this is not the only way of setting up such a system. Run. Setting up an Encrypted Debian System LG #140. By Kapil Hari Paranjape Ever since I heard that the new Debian “etch” installer supports encrypted LVM, I wanted to try having an encrypted disk. Given recent news stories about loss of identity information from stolen laptops, it is certainly not paranoid to want to do this — and if you tell me otherwise you are probably one of those guys trying to steal my identity information! One way would have been to re-install Debian on my laptop from a Debian install CD after saving all my data — but I can already hear sarcastic clucking sounds to the accompaniment of flapping arms folded at the elbows if I even think this way. The whole point of the exercise would be lost if I have to re-configure my laptop all over again. So here goes! Axioms Let me first describe the disk configuration that I like to have as it might be a bit unusual.

/dev/hda1 which is a small (50-100MB) partition for /boot. This allows me to resize filesystems as and when required. Backups Are Important Making Space in the Boot. Xen-tools.org - The Site for Xen automation. Xen Software: xen-tools.
