  • Setting Up A High-Availability Load Balancer (With Failover and Session Support) With Perlbal/Heartbeat On Debian Etch

    ha Author: Falko Timme • Tags: , • Comments: 4

    Setting Up A High-Availability Load Balancer (With Failover and Session Support) With Perlbal/Heartbeat On Debian Etch 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.).

  • Using memcached With Your vBulletin Forum To Reduce Server Load (Debian Etch)

    Author: Falko Timme • Tags: • Comments: 2

    Using memcached With Your vBulletin Forum To Reduce Server Load (Debian Etch) In this article I will explain how you can reduce server load by using memcached together with your vBulletin forum software (I'm assuming you are running vBulletin on Apache2 with mod_php5). memcached is a daemon that can store objects in the system's memory (e.g. results of database queries) which can speed up your web site tremendously. You can use memcached over a network (i.e., install your web application on one server and memcached on another server), but usually you install both on one server to avoid the networking overhead.
