查看Linux下rabbitmq的安装插件：查找

rabbitmq_delayed_message_exchange

 通过命令：rabbitmq-plugins list

此时并没有找到该插件；

附：rabbitmq 插件安装（官网）

下载对应版本，由于我的rabbitmq是3.6.5，所以我安装3.6.x版本； 

下载的压缩包： 

解压后：后缀的.ez

 将插件上传到Linux系统rabbitmq插件目录中，我上面通过ps -ef | grep rabbitmq 命令，已经找到了/usr/lib/rabbitmq/lib/rabbitmq_server-3.6.5/plugins，因此我放在plugins目录下即可。

然后开启rabbitmq_delayed_message_exchange插件

rabbitmq-plugins enable rabbitmq_delayed_message_exchange

再次启动项目，并无报错信息。
