6.2.3. Configuring a High Availability Message Server


For message server redundancy, OpenShift Enterprise uses ActiveMQ's native clustering capability.

Example 6.8. Message Server Configuration

class { 'openshift_origin' :
  # Other settings as appropriate per above examples
  ...

  # Set the msgserver_hostname to the current msgserver host
  msgserver_hostname => <this_msgserver_hostname>,

  # Set the shared password that the cluster members will use
  msgserver_password => <shared_cluster_password>,

  # Specify the hostnames of all of the cluster members.
  msgserver_cluster         => true,
  msgserver_cluster_members => ['msgserver1.openshift.local','msgserver2.openshift.local','msgserver3.openshift.local'],
}
Hosts that have the broker or node role must have the following information as well, even if they are not message server hosts:

Example 6.9. Broker and Node Configuration

class { 'openshift_origin' :
  # Other settings as appropriate per above examples
  ...

  # Specify the hostnames of the msgserver cluster members.
  msgserver_cluster         => true,
  msgserver_cluster_members => ['msgserver1.openshift.local','msgserver2.openshift.local','msgserver3.openshift.local'],
}
