问题：

解决rabbitmq-plugins enable rabbitmq_delayed_message_exchange
：plugins_not_found

我是在docker-compose环境部署的

解决步骤：

1. 挂载进去后，到 rabbbitmq容器的 /opt/rabbitmq/sbin 目录下去
2. 执行./rabbitmq-plugins enable rabbitmq_delayed_message_exchange
   而不是./rabbitmq-plugins enable rabbitmq_delayed_message_exchange-3.13.0.ez
