一、安装前准备
由于dubbo被阿里捐献给了apache,这次安装admin时，参考网上的资料，地址还是停留在之前的链接，踩了不少坑，这里记录下。
dubbo-admin下载地址：
地址一：https://github.com/apache/incubator-dubbo/releases
该地址2.6版本以上的包中没有dubbo-admin ,2.5x版本的有
地址二：https://github.com/apache/incubator-dubbo-ops
该地址中的dubbo-admin模块被单独拎出来了，springboot方式启动，可以直接运行main方法，或者使用 java -jar 方式启动，很方便，有github账号的可以fork一下，推荐使用这个版本，本文介绍的就是该版本 。
二、dubbo-spring-boot-starter的使用
github地址：https://github.com/alibaba/dubbo-spring-boot-starter 最新版本为2.0 ，本文也是使用的该版本。

三、dubbo-admin的启动
下载地址二的包，直接在idea中打开，结构如下：
install完成之后，直接右键DubboAdminApplication Run
修改配置文件，位置在 dubbo-admin /src/main/resource下面
