RabbitMQ启动报unknown exchange type 'x-delayed-message'

RabbitMQ延迟队列插件未安装，导致以下问题：

ShutdownSignalException: connection error; protocol method: #method<connection.close>(reply-code=503, reply-text=COMMAND_INVALID - unknown exchange type 'x-delayed-message', class-id=40, method-id=10)

代表没有找到对应x-delayed-message的exchange type

插件下载地址：https://www.rabbitmq.com/community-plugins.html

下载下来之后将插件复制到rabbit-service的插件目录(自己的安装目录)中

 

然后开启插件服务：

rabbitmq-plugins enable rabbitmq_delayed_message_exchange
