zookeeper的安装参考：

1.pom依赖

2.application.yml配置

spring:
  application:
    name: zookeeper-client-1 #微服务名称
zookeeper:
  address: 127.0.0.1:2181
  timeout: 4000

3.注册微服务

启动上述client工程后，打开bin/zkCli.cmd查看节点：

说明zookeeper-client-1已经成功注册到zookeeper。

另外还可以使用工具ZooViewer查看节点及其详细信息，

可以看到微服务名，计算机地址和端口：

4.增加同一个微服务下的节点

当我们修改application.yml的端口为9080后重启client后（之前8080不要关闭），可以发现该微服务下有两个节点：

可见，增加节点成功。
