eureka 集群搭建出现 。。 org.springframework Cannot Create new Replica Node :JerseyReplicationClient: http://eureka7002.com:7002/eureka/apps/:

这是7001端口对应的yml文件

server:
  port: 7001


eureka:
  instance:
    hostname: eureka7001.com #eureka服务端的实例名称
  client:
    register-with-eureka: false     #false表示不向注册中心注册自己。
    fetch-registry: false     #false表示自己端就是注册中心，我的职责就是维护服务实例，并不需要去检索服务
    service-url:
      #集群指向其它eureka
      #defaultZone: http://eureka7002.com:7002/eureka/
      #单机就是7001自己
      defaultZone: http://eureka7002.com:7002/eureka/
    #server:
    #关闭自我保护机制，保证不可用服务被及时踢除
    #enable-self-preservation: false
    #eviction-interval-timer-in-ms: 2000

这是7002对应的yml文件
