RabbitMQ

Blueriq supports RabbitMQ as the message broker. The following page describes how to install RabbitMQ: Installing RabbitMQ

After RabbitMQ has been installed, we can configure the queues, exchanges and the bindings between the exchanges and queues. The default configuration has been attached to this page. This file is a JSON file which contains all queues, exchanges and bindings necessary for the DCM setup. It can be imported in the RabbitMQ dashboard in the "Overview" tab, under "Import definitions". 

After importing the file it might be necessary to reconfigure the users. To add a new user so you can remove the guest user. please see: https://www.rabbitmq.com/access-control.html
