步骤

1. 启动本地的 Zookeeper 服务，端口号为 2181

   这里 Zookeeper 可以直接使用单机版，如果需要配置集群版的，可以参考 http://xkcoding.com/2017/11/01/zookeeper-cluster.html

2. 启动两个 spring-boot-demo-dubbo-provider 程序，端口号分别使用 8082、8083

3. 启动 spring-boot-demo-dubbo-consumer 程序，端口号为 9090

4. 浏览器输入 http://localhost:9090/greet?name=test

   可以看到，8082和8083端口随机打印

   Hello, test, from port: 8082

   或

   Hello, test, from port: 8083

5. 本地启动 dubbo-admin 可以查看服务提供方和消费方，也可以配置负载均衡策略等等

   关于 dubbo-admin 的安装和配置等，可以参考 http://xkcoding.com/2017/11/08/dubbo-admin-install.html
