Resetting the RabbitMQ cluster

1. Run this command on both nodes:

vcac-vami rabbitmq-cluster-config reset-rabbitmq-node command on both nodes.

2. Run this command on the first node:

vcac-vami rabbitmq-cluster-config set-cluster-node command on the first node.

3. Run this command on the first node:

vcac-vami rabbitmq-cluster-config generate_join_cluster_variables
 

Note:  Make a note of username, password, cookie, host, and use_longname.

4. Run this command on the second node:
