Unable to run qpid in a cluster under cman
------------------------------------------
Key: QPID-3483
URL: https://issues.apache.org/jira/browse/QPID-3483
Project: Qpid
Issue Type: Bug
Components: C++ Clustering
Affects Versions: 0.13
Reporter: Alan Conway
Assignee: Alan Conway
Description of problem:
Section 7.1 of user guide "Starting a Broker in a Cluster" describes a way how
to start qpidd in a cluster under cman. That does not work on RHEL 6.x where
corosync requires /etc/corosync/uidgid.d to authenticate non-root access to
corosync. But when corosync runs under cman, cman overrides configuration
parser of corosync by its own parser, taking into account only
/etc/cluster/cluster.conf configuration. That file has no option to setup
uidgid at all.
At the end, as qpidd runs under qpidd user, there is no way to run qpidd in a
RHEL6.x cluster under cman.
Version-Release number of selected component (if applicable):
MRG 2.0 & RHEL 6.x
How reproducible:
100%
Steps to Reproduce (apply the below to at least 3 nodes in a cluster):
1. Edit /etc/corosync/uidgid.d/qpidd per manuals
2. Setup /etc/cluster/cluster.conf to have some working cman configuration
(e.g. use file from https://access.redhat.com/kb/docs/DOC-58232)
3. /etc/qpidd.conf has:
cluster-mechanism=PLAIN
cluster-username=guest
cluster-password=guest
cluster-name=TEST
cluster-cman=yes
4. service cman start
5. service qpidd start
Actual results:
qpidd will fail with:
Starting Qpid AMQP daemon: Daemon startup failed: Failed to initialize CPG.:
security (100)
Expected results:
qpidd will start properly.
