Steps to setup a RabbitMQ cluster on RHEL 6.4 64-bit machine:

Installation on all boxes:
  • sudo rpm -ivh  erlang-R15B-02.1.el6.x86_64.rpm –> VMWare erlang version
  • sudo rpm -ivh  rabbitmq-server-3.1.5-1.noarch.rpm –> RabbitMQ version sudo rabbitmq-plugins enable rabbitmq_management –> Enable RabbitMQ management plugin
  • sudo chkconfig rabbitmq-server on –> ”Start the daemon by default when the system boots”
  • sudo rabbitmq-server -detached
  • sudo rabbitmqctl status
  • view the erlang cookie on Node1 –> sudo vi /var/lib/rabbitmq/.erlang.cookie
  • on Node 2 follow the following steps:
    • sudo chmod 755 /var/lib/rabbitmq/.erlang.cookie
    • sudo vi /var/lib/rabbitmq/.erlang.cookie
    • delete value and replace it with the value from Node 1, exit and save the file
    • sudo chmod 400 /var/lib/rabbitmq/.erlang.cookie
    • sudo reboot
Now the actual stuff, adding nodes to cluster:
  • Node 2 –> sudo rabbitmqctl stop_app
  • sudo rabbitmqctl join_cluster rabbit@node1
  • sudo rabbitmqctl start_app

Login to Node1 management console and on overview page, you should find Node 1 and Node 2 listed. Repeat the above steps to join more nodes to the cluster.
