诈一看启动时正常的，但是一访问：

我的配置文件

server:
  port: 6000

spring:
  application:
    name: eureka-server-demo

eureka:
  instance:
    hostname: 127.0.0.1
    lease-expiration-duration-in-seconds: 30
    lease-renewal-interval-in-seconds: 30
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://$eureka.instance.hostname:$server.port/eureka/

就是感觉没啥毛病，但就很是郁闷呀，结果就直接把项目删除，重新搭建，啥也不改，竟然就成功了，对比发现就端口不一样，结果换了个端口，莫名其妙好了，经查资料说 6000端口一般是***端口，一般都是关闭的，所以才导致的这个问题，还能怎么办，改个端口呗！！！
