RabbitMQ Cluster setup on RHEL 6.4

Steps to turn off iptables:

• sudo service iptables save
• sudo service iptables stop
• sudo chkconfig iptables off

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

Setup Erlang cookie:

• 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.
