zookeeper注册服务中心

zookeeper代替eureka

长时间没心跳会删除

eureka可以有90秒等待以及保护措施，zookeeper更坚决些

是分布式协调工具，可以实现注册中心功能

需要先在liunx上安装zookeeper

需要开放端口 2181 2888 3888

#8004表示注册到zookeeper服务器的服务提供者端口号
server:
  port: 8004

spring:
  application:
    #服务别名注册到zookeeper的服务名称
    name: cloud-provider-payment
  cloud:
    zookeeper:
      connect-string: 192.168.68.128:2181

@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain8004{
    public static void main(String[] args){
        SpringApplication.run(PaymentMain8004.class,args);
    }
}

服务注册后检查

./zkCli.sh    开启客户端

或者在idea上看
