ApacheDS/Pacemaker in cluster mode

daf1kpp · 06-07-2015, 03:00 PM

Hi,
I need to create cluster of 3 nodes with LDAP (ApacheDS - directory server).
I am already familiar how to create cluster with pacemaker and it's resources, but so far I didn't find any information how to create apacheds ldap as resource. There are only examples for OpenLDAP (ocf:heartbeat:slapd).

How to configure pacemaker to have ApacheDS in cluster mode?

Thanks

There are two types of clusters, high availability or high performance, which kind are you building?

That's a high availability cluster.

You'd probably, in a high availability cluster, make the instance(s) running ApacheDS the resource.

ApacheDS probably doesn't know or care if it's running in cluster mode, it's the instance, the underlying OS that has to overcome the problems associated with running in a distributed framework.

In short, if you install RHEL 6.6 on your cluster and then install apacheDS on the RHEL 6.6 server you just installed on your cluster, then snap an image of that installation and do your resource mapping for pacemaker with the understanding you are failing over the instance, not the application, you will probably have a better outcome.

At least that would be my hope.

Thanks for answer, but adding ApacheDS as resource for pacemaker software has advantages i really need to have.

Do you know how to add apacheds as resource for pacemaker?
