我正在尝试创建两个Eureka服务器实例。但是当我运行它时，它们无法互相注册。我得到的错误是：
com.netflix.discovery.DiscoveryClient：从eureka服务器获取所有实例注册表信息 2017-11-02 15：51：14.125 ERROR 34 --- [main] c.n.d.s.t.d.RedirectingEurekaHttpClient：请求执行错误
com.sun.jersey.api.client.ClientHandlerException：java.net.ConnectException：拒绝连接（拒绝连接） 在com.sun.jersey.client.apache4.ApacheHttpClient4Handler.handle（ApacheHttpClient4Handler.java:187）〜[jersey-apache-client4-1.19.1.jar！/：1.19.1]
主要申请文件是：
@SpringBootApplication
@EnableEurekaServer
public class RegistrationServer {
public static void main(String[] args) {
System.setProperty("spring.config.name", "registration-server");
SpringApplication.run(RegistrationServer.class, args);
}
}
registration-server.yml是：
---
spring.profiles: server-1
eureka:
instance:
hostname: localhost #eureka-server
server:
enableSelfPreservation: false
client:
register-with-eureka: true
fetch-registry: true

eureka的两个实例，即server-1和server-2都正常运行。但他们没有相互注册。
答案 0 :(得分：1)
尝试修改您的registration-server.yml，如下所示：您在defaultZone之前错过了两个.yml文件的 ONE 空间。顺便说一句，这些文件中仍有许多语法错误。
对于eureka-server-1：
eureka:
...
client:
...
serviceUrl:
defaultZone: http://server-2:2424/eureka/
对于eureka-server-2：
eureka:
...
client:
...
serviceUrl:
defaultZone: http://server-1:2323/eureka/
这是我的一个尤里卡服务器设置，它可以很好地使两个服务器相互注册：
spring:
application:
name: registry
server:
port: 2323
eureka:
server:
eviction-interval-timer-in-ms: 15000
client:
fetch-registry: true
register-with-eureka: true
serviceUrl:
defaultZone: ${eureka_url:http://localhost:2424/eureka}
instance:
instance-id: ${spring.application.name}:${random.value}
hostname: ${eureka_host:localhost}
secure-port: ${server.port}
non-secure-port-enabled: true
non-secure-port: ${server.port}
答案 1 :(得分：0)
我不确定Eureka是否可以注册另一个Eureka，但概念上看起来它也是一个正在运行的服务。因此可以充当服务和服务器（尤里卡）。但我不完全确定。
无论如何，我认为你应该在你的Eurekaserverapplication中试试这个
@SpringBootApplication
@EnableEurekaClient
@EnableEurekaServer
public class RegistrationServer {
public static void main(String[] args) {
System.setProperty("spring.config.name", "registration-server");
SpringApplication.run(RegistrationServer.class, args);
}
}
尝试将@EnableEurekaClient或@EnableDiscoveryClient放入启动应用程序。由于您的应用程序应该充当客户端和服务器。
所以，我认为那些注释很重要。
答案 2 :(得分：0)
不确定，尝试更改
eureka:
instance:
hostname
到服务器-1＆＃39;和＆＃39; server-2＆＃39;相应
