I believe many inexperienced people don't know what the rabbitmq image queue is. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Ordinary cluster: a RabbitMQ cluster is made up of multiple broker nodes, so in terms of the overall availability of the service, the cluster is flexible to single point of failure, but it should also be noted that although exchange and binding can survive a single point of failure, queue and the message held on it are not, because queue and its contents are only stored on a single node. Therefore, the failure of a node shows that its corresponding queue is not available.

Mirror queue: solves the problem that queue is out of sync in a general cluster, so that a node in the cluster can still hang up and be available.

The rabbitmq image queue feature needs to be implemented with rabbitmq policy enabled and based on rabbitmq policy. The policy is used to control and modify a cluster-wide vhost queue behavior and Exchange behavior. If the policy is enabled by any node in the cluster, the policy will be automatically synchronized to the cluster node.

Command line operations:

Rabbitmqctl set_policy ha-all "^ queue"'{"ha-mode": "all"}'

Web interface operation:
