无法添加Rabbitmq插件

Question

我正在关注此http://www.rabbitmq.com/plugin-development.html链接以构建rabbitmq插件https://github.com/rabbitmq/rabbitmq-web-mqtt

构建完成后，

仅将rabbitmq_mqtt.ez复制到/usr/lib/rabbitmq/lib/rabbitmq_server-3.6.2/plugins

正在运行sudo rabbitmq-plugins enable rabbitmq_web_mqtt 显示：

The following plugins have been enabled:
  cowlib
  cowboy
  rabbitmq_web_mqtt

Applying plugin configuration to rabbit@manish-Lenovo-G510... failed.

正在运行sudo rabbitmq-plugins list

我无法使用paho JS客户端进行连接。那么是什么导致了这个问题呢？我尝试了端口1888,8083,8883,15675

Lager仅在版本3.7.0中，很可能是您构建了master分支。

要构建插件版本3.6.2，您应该：

    git clone https://github.com/rabbitmq/rabbitmq-public-umbrella.git .
    make up BRANCH=rabbitmq_v3_6_2
    cd deps/rabbitmq_web_mqtt
    make dist

修改

您必须禁用并删除旧的.ez文件，复制新文件后，您必须启用该插件。

刚试过，它运行正常，请参阅测试：
