Hi, I'm new to HA with Linux and looking for a possibility to build a HA cluster with apache, mysql and a central file storage. I want to use heartbeat-2 to monitor the nodes and services, for sure nothing new and many people have done this before, but somehow I have difficulties to get started. I'm still not sure if heartbeat is all I need to get such a cluster up and running, there is so many other software around which seems also to fit our needs (pacemaker, openais, etc.). So the first question would be if I can do what I want with heartbeat-2?
I have 2 identical Debian etch servers with heartbeat-2 installed on every machine and first want to configure nodes, the ressources and the constrains. Because of the new XML format used in heartbeat-2 another difficulty comes up :(. Because I'm blind and the GUI to configure nodes, ressources and constrains is not accessible for me :(. Editing the cib.xml file manualy is not recommended, but what other possibilities do I have to create a working configuration? Now I have the following questions? - Is heartbeat-2 the software I'm looking for, can I build a HA cluster with apache, mysql and a central file storage with heartbeat-2 only? - Is there a step to step howto somewhere out that describes all necesary steps that are needed to build such a cluster? I found many howtos but either they described a setup with heartbeat-1 or the graphical frontend was used to create the configuration. - Is there another way to build the configuration of nodes, ressources and constrains without using the GUI? I saw cibadmin for example but with this tool I have to know the XML structure of the cib.xml file very detailed it seems. Also I read something about a webinterface that can be used but also I was not able to get more detailed information :(. Sorry for the newby questions but for a beginner the whole thing is a little confusing, especialy if it is not possible to go the normal way to configure a HA cluster with heartbeat-2. Thanks for anny help or tip that can help me to get started!
