The mirror queue is based on a common cluster mode, so you have to configure the normal cluster (refer to the previous Windows RabbitMQ cluster ) before you can set up the mirroring queue.Create a new queue on the cluster server: The mirroring queue is implemented through the RABBITMQ configuration policy: The mirroring queue provides three modes:? All: The entire node queue is mirrored;? Exactl

Although the use of RABBITMQ command line to view the management connection, queue, switch is also very convenient, but the command line interface is not always the web GUI more humane, so looked at the next RABBITMQ's official website, did not expect to find this good thing:

Example: implementation of RPC
This is an example of using RPC via AMQP, and RPC is a synchronous process that needs to wait for a response. In the actual application requires special messages, server may be slow performance, server may be shut down. Whether we must use RPC, or if we can replace it in an asynchronous way. Here, we are just demonstrating how to implement an RPC using the message management provided by RABBITMQ. The idea is as follows
