如何在不同主机上的eureka服务器上注册eureka客户端.春季靴 [英] How to register eureka-clients with eureka-server on different hosts. Spring-boot

问题描述

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.

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.

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:

Now I want to register a service which is running on a linux machine. My properties looks like that:

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localhost的eureka服务器上注册. (最后，它与在localhost上运行的服务相同)

But the service is not able to register on eureka server on localhost. (At the end its the same service which runs on localhost)

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

但是我可以从在本地主机上运行的配置服务中获取配置文件.

But I'm able to get my configuration files from my config-service running on localhost.

我需要将哪些服务从Linux计算机(客户端)注册到localhost(服务器)，以将服务注册到eureka?

我使用以下注释:

服务:

@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaClient
public class MyServiceApplication {

Eureka服务器:

Eureka-Server:

@SpringBootApplication
@EnableEurekaServer
public class EurekaServiceApplication {

P.S .:相反的方法也不起作用.意味着在Linux机器上具有eureka服务器，在localhost上具有服务.获得相同的例外.

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.

Eureka服务器属性:

Eureka-Server properties:

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计算机. (172.25.82.108)

testsrv is the linux machine. (172.25.82.108)

推荐答案

将我的一项服务的.properties更改为.yml文件并更正了defaultZone的拼写错误后，一切正常.

After changing .properties to .yml file of one of my service and corrected misspelling of defaultZone everything works like expected.
