如何在不同主机上的eureka服务器上注册eureka客户端。Spring靴

我在本地主机上运行我的eureka服务器。我可以在运行服务的localhost上注册其他所有设备，一切正常。

现在，我想注册一个在Linux机器上运行的服务。我的属性如下所示：

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/

但是该服务无法在本地主机上的eureka服务器上注册。（最后是在本地主机上运行的相同服务）

我得到那些例外：

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

但是我可以从在localhost上运行的config-service中获取配置文件。

我使用以下注释：

服务：

@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaClient
public class MyServiceApplication {

尤里卡服务器：

@SpringBootApplication
@EnableEurekaServer
public class EurekaServiceApplication {

PS：同样，相反的方法不起作用。意味着在Linux机器上具有eureka服务器，在localhost上具有服务。获取相同的例外。

Eureka-Server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

testsrv是linux机器。（172.25.82.108）
