Druid 基础使用-操作篇（Imply ）

一、Imply

    Druid 原生的配置较麻烦，在上一篇单机版安装中有所涉及
   Imply 基于Druid 进行了一些组件的开发，提供开源社区版本和商业版，简化了部署，开发了一些应用.https://imply.io/product

二、

安装

1. 下载nodejs 安装(http://jingyan.baidu.com/article/dca1fa6f48f478f1a5405272.html)
2. .安装imply
   1. 下载最新版本 imply-1.3.1.tar  https://imply.io/download
   2. tar -xzf imply-1.3.1.tar
3. 启动
    1[root@Druid imply-1.3.1]# bin/supervise -c conf/supervise/quickstart.conf  -可以nohup 后台执行

三、Imply 数据的发送
        1.修改 tranquility 组件下server.josn 中的数据相关信息 --表名称、维度列、指标列
         修改后的数据结构如下
