Hi there, I'm in the situation that I need a new HA-cluster in operation, but I want to limit the needed resources to a minimum. After reading the series on the high availability nfs/apache/mysql clusters + loadbalancer I have a couple of questions, I wonder if anyone could give me a hand in this. I'm going to run a php/mysql web-application with several interactive elements (= heavy DB usage) and some data-hogs (movies on demand). At this moment I think that fail-over is more important than pure performance so the setup I have in mind at this moment consists of: 2x loadbalancer 2x webserver 2x db-server + nfs server My questions: - Is this the logical combination or is it better to combine webserver & nfs server on 1 box? - The MySQL clustering solution has loadbalancer 1 as the management node. Shouldn't it be installed on loadbalancer 2 as well? It seems to me that the approach from the tutorial still creates a single point of failure. What happens to the Cluster if LB 1 crashes and DB1 crashes after that? Thanks in advance!
