+====== Install RabbitMQ on RedHat 6.6 ======
+If docker is available on the machine then rabbit can be setup via :
+<code>
+docker run -d -p 5672:5672 -p 15672:15672 -p 15674:15674 -e RABBITMQ_DEFAULT_VHOST=admin -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin --hostname rab1 --name rab1con -e RABBITMQ_ERLANG_COOKIE='secret cookie here' rabbitmq:3-management
+# Open url http://localhost:15672 (create user and virtual-host using UI)
+</code>
