Set Up A High-Availability Load Balancer With Perlbal/Heartbeat On Debian Etch

Post date: January 13, 2009, 12:01 Category: Installing Views: 3962 Comments
Tutorial quote: This article explains how to set up a two-node load balancer in an active/passive configuration with Perlbal and heartbeat on Debian Etch. 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. Perlbal is session-aware, which means you can use it with any web application that makes use of sessions (such as forums, shopping carts, etc.).

My First Linux Server, Part 1

Post date: April 14, 2005, 22:04 Category: Miscellaneous Views: 5210 Comments
Tutorial quote: Many small businesses are turning to Linux as way to swim against the tide of rising software costs. Are you thinking about diving into Linux for your small business? From the outside, Linux can appear to be a deep ocean of strange jargon in unchartered waters. Who has the time to wade through all that to save a few clams? With Linux, it's not a sink or swim proposition.

Linux is now a lot simpler than you may think. We can provide you with the easiest, simplest, no-problem process for installing Linux on a PC. After going through this simple installation process, you will have a basic machine that you can configure into any kind of server, workstation, or office desktop. Future articles in this My First Linux Server series will help you build productive, Linux-based servers and small office workstations.

The best choices for your first Linux machine are probably the popular Red Hat Linux or SUSE Linux, primarily because both are easy to install and configure. Additionally, these companies are sound choices for the home office or small business. Both vendors have specialized in Linux for many years and offer full corporate product lines supporting your expansion.

Installing Ubuntu Or Fedora From A Windows Or Linux System With UNetbootin

Post date: October 7, 2007, 09:10 Category: Installing Views: 4613 Comments
Tutorial quote: UNetbootin is a tool that allows you to install various Linux distributions (Ubuntu, Fedora, Mandriva, OpenSuSE, Debian, ArchLinux) from a Windows or a Linux desktop over the internet (i.e., you do not need to burn the Ubuntu, Fedora, ... CDs). Unlike the Ubuntu installation with Wubi, real partitions are created during the installation. In the end, you have a dual-boot system (Linux/Windows or Linux/Linux).

Connecting to a Wireless LAN with Linux, Part 1

Post date: April 13, 2005, 19:04 Category: Hardware Views: 4304 Comments
Tutorial quote: Wireless hardware for Linux is a moving target. The wireless network adapter that worked fine with Linux yesterday may be released with an unsupported radio chipset today, and with no indication of the change. So buyer beware--always confirm the chipset before you buy. The good news is a lot of wireless adapters have native Linux support, and for those that don't, the NdisWrapper utility lets you use the Windows drivers on your Linux box.
