In this article we are going to setup RabbitMQ Cluster on CentOS 7 Operating system.
RabbitMQ is an Open Source message-queuing software called a message broker or queue manager. We can say , it is a software where queues can be defined, applications may connect to the queue and transfer a message onto it. The queue-manager software stores the messages until a receiving application connects and takes a message off the queue. The receiving application then processes the message in an appropriate manner. A message can include any kind of information for example, it could have information about a process/task that should start on another application may be on another server or it could be just a simple text message.
