Enabling Plug-ins

After creating a RabbitMQ instance, you can enable the plug-ins listed in the following table. The plug-ins are disabled by default when the instance is created.

RabbitMQ plug-ins can be used for testing and service migration. Do not use them for production. For details, see Notes and Constraints.

When plug-ins are enabled, the instance will not be restarted. However, enabling plug-ins rabbitmq_mqtt, rabbitmq_web_mqtt, rabbitmq_stomp, and rabbitmq_web_stomp will restart Keepalived and disconnect the instance. After the instance is disconnected, it may be automatically reconnected depending on the service logic.
