Debian How To Set Up A Loadbalanced High-Availability Apache Cluster
Post date: April 28, 2006, 06:04 Category: Network Views: 1723 Comments: 0
Tutorial quote: 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.

Debian Splitting updatedb into daily and weekly
Post date: April 21, 2006, 12:04 Category: System Views: 1034 Comments: 0
Tutorial quote: We all appreciate the locate command when we are such in a hurry we cannot afford a full and in-elegant find. What we like a little less, though, is the updatedb script consuming up all our disk bandwidth at each boot, summoned by anacron.

Of course, this is only the case if you are running a "desktop" machine: since you turn it on when you need to do some work, then you long for a way to shorten the period of reduced usability forced by updatedb.

Inversely, if you run a server that never goes down, and you successfully schedule your updatedb tasks late at night, then this article is not for you.
