### 查看Linux下rabbitmq的安装插件：查找 ###

rabbitmq_delayed_message_exchange

**通过命令：rabbitmq-plugins list**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3NDk1Nzg2_size_16_color_FFFFFF_t_70][]

**此时并没有找到该插件；**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3NDk1Nzg2_size_16_color_FFFFFF_t_70 1][]

### 附：[rabbitmq 插件安装（官网）][rabbitmq] ###

**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； **

**解压后：后缀的.ez**

![20190924133156888.png][]

** 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。
