Dubbo-admin管理平台搭建
Dubbo的使用，其实只需要有注册中心，消费者，提供者这三个就可以使用了，但是并不能看到有哪些消费者和提供者，为了更好的调试，发现问题，解决问题，因此引入dubbo-admin。通过dubbo-admin可以对消费者和提供者进行管理。
Dubbo-admin可以对注册到zookeeper注册中心的服务或服务消费者进行管理，但是否正常对Dubbo服务没有影响，管控台也不需要高可用，因此可以单节点部署。
1、从官网下载源码
# git clone https://github.com/alibaba/dubbo.git
2、配置dubbo.properties：
$ vim dubbo/dubbo-admin/src/main/webapp/WEB-INF/dubbo.properties
dubbo.registry.address=zookeeper://192.168.10.101:2181 注：这里说明下zookeeper地址，这个指的是已经部署好的注册中心zookeeper的IP地址，端口号不变
dubbo.admin.root.password=root
dubbo.admin.guest.password=root
3、进行构建并打成war包
# cd dubbo/dubbo-admin
# mvn package -Dmaven.skip.test=true
4、把构建好的war包放到tomcat下运行，war包在dubbo/dubbo-admin/target/下
5、用浏览器打开地址 http://localhost:8080/dubbo-admin，账号密码都是 root，则就可以进入到 dubbo管理控制台
FAQ：
一、打包时Maven依赖找不到
1.错误：[ERROR] Failed to execute goal on project dubbo-common: Could not resolve dependencies for project
2.原因：dubbo-admin工程下pom.xml中有些jar包不能被公网访问到
3.解决办法：
- 根据报的依赖错修改version 比如：
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>2.5.3</version>
</dependency>
2.下载相应的jar包放到本地仓库
3.参考网址：https://github.com/alibaba/dubbo/issues/22
