Eureka服务器集群错误（对等感知）

我的问题是关于Spring Cloud Eureka：我正在尝试运行Eureka集群（2个节点，localhost:8761，localhost:8762），但出现一些错误：

重定向EurekaHttpClient：
请求执行错误：
endpoint=DefaultEndpoint{serviceUrl='http://localhost:8761/eureka/}

RetryableEurekaHttpClient：
请求执行失败，消息：java.net。ConnectException：连接被拒绝

DiscoveryClient：DiscoveryClient_UNKNOWN/192.168.1.4:8761-无法刷新其缓存！status=无法在任何已知服务器上执行请求

以下是application. yml文件：

服务器1：

spring:
    profiles: eureka-peer1

server:
    port: 8761

eureka:
    instance:
        hostname: eureka-peer1
    client:
        registerWithEureka: true
        fetchRegistry: true
        serviceUrl:
            defaultZone: http://eureka-peer2:8762/eureka/

服务器2：

spring:
   profiles: eureka-peer2

server:
    port: 8762

eureka:
   instance:
       hostname: eureka-peer2
   client:
       registerWithEureka: true
       fetchRegistry: true
       serviceUrl:
           defaultZone: http://eureka-peer1:8761/eureka/

文件 /etc/hosts：

127.0.0.1   localhost
127.0.0.1   eureka-peer1
127.0.0.1   eureka-peer2

ErekaService1Application.java，ErekaService2Application.java：

package com.example.eurekaservice1;

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

@SpringBootApplication
@EnableEurekaServer
@EnableEurekaClient
public class EurekaService1Application {

    public static void main(String[] args) {
        SpringApplication.run(EurekaService1Application.class, args);
    }

}

删除@EnableEurekaClient并将“stersterAnyEureka”和“fetch删减”设置为“false”会得到相同的结果。

此外，具有这些属性的独立模式会导致相同的错误：

spring:
  profiles: eureka-peer1

server:
  port: 8761

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false

这是pom. xml文件，使用start.spring.io自动生成：
