Binding a RabbitMQ Queue

Binding a queue is to relate an exchange to a queue. In this way, producers send messages to exchanges and exchanges route these messages to related queues.

This section describes how to bind queues for an exchange on the console. Exchanges with queues bound can route and store messages to the queues. An exchange can be bound with multiple queues.

Notes and Constraints

In RabbitMQ 3.x.x, the exchange (AMQP default) cannot be bound with any queue.
Internal exchanges can only be bound with exchanges and not queues.

Prerequisites

An exchange has been created.
A queue has been created.

Binding a Queue to an Exchange

Log in to the console.
In the upper left corner, click and select a region.

Select the region where your RabbitMQ instance is.
Click and choose Application > Distributed Message Service for RabbitMQ to open the console of DMS for RabbitMQ.
Click an instance name to go to the instance details page.
In the navigation pane, choose Virtual Hosts.

On the Exchange tab page, click Bind Exchange in the row containing the desired exchange. The Bind Exchange page is displayed.

**Table 1** Binding parameters
Parameter	Description
Type	Select the binding type: To bind a queue, select Queue.
Target	Select a target queue to be bound.
Routing Key	Enter a key string to inform the exchange of which queues to deliver messages to. This parameter is required by direct exchanges and topic exchanges. Such exchanges route messages to queues with the routing keys matched. If this parameter is not set, exchanges route messages to all the bound queues.
