Eureka对等感知示例不起作用

Question

我在运行Eureka服务器示例时面临问题，以理解对等感知的概念。我有以下尤里卡服务：

package com.micro.eurekaserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaServer
public class EurekaServerMicroServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerMicroServiceApplication.class, args);
    }
}

application.yml

spring:
  profiles: peer1
server:
  port: 8761
eureka:
  instance:
    hostname: peer1
  client:
    serviceUrl:
      defaultZone: http://peer2:8762/eureka/

spring:

  port: 8762
eureka:
  instance:
    hostname: peer2
  client:
    serviceUrl:
      defaultZone: http://peer1:8761/eureka/

spring:
  application:
    name: eureka

127.0.0.1   peer2
localhost   peer1
localhost   peer2

com.netflix.discovery.DiscoveryClient    : Can't contact any eureka nodes - possibly a security group issue?

我在日志中还注意到tomcat嵌入式服务器是在端口8080而不是8761/8762上启动的，不知道为什么？

请救命！

尝试从应用程序.java中删除@EnableDiscoveryClient。我的是这样的：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
