Hi, I'm reaching out for a little help and pointers with regard to qpid clustering.
I'm coming into this with nearly zero qpid experience so I will try to be as complete as possible. I am attempting to set up a qpid cluster so that we can scale out our qpid clients across multiple qpid servers. Is it best practice to have a primary enqueue node and dequeue from the secondary nodes in the cluster? My understanding is that replication is geared more for fault tolerance and disaster recovery, and that clustering is geared towards supporting large numbers of concurrent activity. I am currently working on getting qpid clustering working as described here: https://cwiki.apache.org/qpid/starting-a-cluster.html I am running qpid v 0.5 on Fedora 12. I have the following rpms installed: qpidc-0.5.829175-2.fc12.x86_64 qpidd-0.5.829175-2.fc12.x86_64 qpidd-cluster-0.5.829175-2.fc12.x86_64 When I start qpidd and pass the --cluster-name=TEST_CLUSTER option, qpidd aborts with the following error: Starting Qpid AMQP daemon: Daemon startup failed: Cannot join CPG group DEV_CLUSTER: try again (6) I believe I have corosync and pacemaker working. If I start corosync, it takes a bit of time before the crm commands work, but once everything spins up I don't see any warnings when I run: crm_verify -L (no output/warnings) crm configure show node edisondev3 property $id="cib-bootstrap-options" \ dc-version="1.0.5-ee19d8e83c2a5d45988f1cee36d334a631d84fc7" \ cluster-infrastructure="openais" \ expected-quorum-votes="2" \ stonith-enabled="false" \ stonith-enable="false" I've double checked my bindnetaddress in corosync.conf. It lines up with the wiki article and agrees with the output of /sbin/route. I double checked my uidgid.d/qpid file. Initially I had the uid wrong and was getting a security error when I started qpid. Now that I have the correct uid/gid, I am seeing the 'try again' error above. Any tips would be appreciated. -- J. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:[email protected]
