查看Linux下rabbitmq的安裝插件：查找

rabbitmq_delayed_message_exchange

通過命令：rabbitmq-plugins list

 

 此時並沒有找到該插件；

附：rabbitmq 插件安裝（官網）

  https://www.rabbitmq.com/community-plugins.html

 

 下載對應版本，由於我的rabbitmq是3.6.5，所以我安裝3.6.x版本；

 

 然后開啟rabbitmq_delayed_message_exchange插件

rabbitmq-plugins enable rabbitmq_delayed_message_exchange

再次啟動項目，並無報錯信息。

Error: Channel closed by server: 406 (PRECONDITION-FAILED) with message "PRECONDITION_FAILED - Invalid argument, 'x-delayed-type' must be an existing exchange type"　

這個問題困擾我了一會兒，詳情可見 Github Issues rabbitmq-delayed-message-exchange/issues/19，正確操作如下圖所示：
