java - 如何在不同主机上向 eureka-server 注册 eureka-clients。 Spring Boot

Question

我在我的本地主机上运行我的 Eureka 服务器。我能够在本地主机运行的服务上注册我的所有其他服务，一切都按预期工作。

现在我想注册一个在 linux 机器上运行的服务。我的属性看起来像这样:

spring.application.name=myService-service
spring.cloud.config.uri=http://myMachine.domain.lan:8888
server.port=8002
eureka.client.service-url.default-zone=http://myMachine.domain.lan:8761/eureka/

但该服务无法在本地主机上的 Eureka 服务器上注册。 (最后它是在本地主机上运行的相同服务)

我得到那些异常:

java.net.ConnectException: Connection refused
com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

但我能够从在本地主机上运行的配置服务获取我的配置文件。

从 linux 机器(客户端)到本地主机(服务器)将我的服务注册到 eureka 需要哪些配置？

我使用这个注解:

服务:

@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaClient
public class MyServiceApplication {

Eureka 服务器:

@SpringBootApplication
@EnableEurekaServer
public class EurekaServiceApplication {

P.S.: 反之亦然。意味着在 linux 机器上有 eureka 服务器，在本地主机上有服务。获取相同的异常。

Eureka 服务器属性:

spring.application.name=eureka-service
spring.cloud.config.uri=http://myMachine.domain.lan:8888
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.instance.hostname=KBHWS242.myDomain.lan
eureka.instance.prefer-ip-address=true

将我的一项服务的 .properties 更改为 .yml 文件并更正 defaultZone 的拼写错误后，一切都按预期进行。
