title: How to register eureka-clients with eureka-server on different hosts. Spring-boot
body: <p>I'm running my eureka-server on my localhost. I'm able to register all my other on localhost running services and everthing works like expected.</p>
  
  <p>Now I want to register a service which is running on a linux machine. My properties looks like that:</p>
  
  <pre><code>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/
  </code></pre>
  
  <p>But the service is not able to register on eureka server on localhost. (At the end its the same service which runs on localhost)</p>
  
  <p>I get those exceptions:</p>
  
  <pre><code>java.net.ConnectException: Connection refused
  com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server
  </code></pre>
  
  <p>But I'm able to get my configuration files from my config-service running on localhost.</p>
  
  <p><strong>Which configurations do I need to register my service to eureka from linux machine(client) to localhost(server)?</strong></p>
  
  <p>This annotations do I use:</p>
  
  <p>Service:</p>
  
  <pre><code>@SpringBootApplication
  @EnableDiscoveryClient
  @EnableEurekaClient
  public class MyServiceApplication {
  </code></pre>
  
  <p>Eureka-Server:</p>
  
  <pre><code>@SpringBootApplication
  @EnableEurekaServer
  public class EurekaServiceApplication {
  </code></pre>
  
  <p>P.S.:Also the opposit way is not working. Means having eureka server on linux machine and the services on localhost. Get the same exceptions.</p>
  
  <p><strong>Edit1:</strong></p>
  
  <p>Eureka-Server properties:</p>
  
  <pre><code>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
  </code></pre>
  
  <p><strong>Edit2:</strong></p>
  
  <p>testsrv is the linux machine. (172.25.82.108)</p>
