RabbitMQ must be installed and configured after Magento Community Edition and before Magento Enterprise Edition.
RabbitMQ is is an open source message broker that offers a reliable, highly available, scalable and portable messaging system.
Message queues provide an asynchronous communications mechanism in which the sender and the receiver of a message do not contact each other. Nor do they need to communicate with the message queue at the same time. When a sender places a messages onto a queue, it is stored until the recipient receives them.
Magento 2.0 Enterprise Edition (EE) uses RabbitMQ to manage these message queues. RabbitMQ cannot be used with Community Edition (CE) installations.
The message queue system must be established before you install Magento. The basic sequence is
- Install RabbitMQ and any prerequisites.
- Configure RabbitMQ.
- Configure your message queue topology.
A basic message queue system can be implemented on EE without using RabbitMQ. See Configure message queues
