spring - Eureka server和eureka client要分开tomcat服务器

Question

我正在寻找一种能够将 Eureka 服务器部署到与 Eureka 客户端不同的 tomcat 服务器的方法。

这是客户端application.yml:

eureka:
  client:
    registryFetchIntervalSeconds: 5
  instance:
    preferIpAddress: true
    leaseRenewalIntervalInSeconds: 10

server:
  port: 8080

spring:
  application.name: my-client
  jmx:
      default-domain: my-client

服务器 application.yml 看起来像:

server:
  port: 8761
eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false

如果我将它们部署到同一个 tomcat 服务器，它会工作得很好。但是，如果我仅使用服务器启动 tomcat，然后再使用客户端启动服务器，则会出现以下错误:

bootstrap.yml 和 application.yml 有什么区别？

如有任何帮助，我们将不胜感激!

您的客户端 application.yml 没有关于您的 eureka 服务器运行位置的信息。客户端应该向 eureka 服务器注册，为此您需要配置您的客户端 application.yml如下

eureka:
 client:
  serviceUrl:
       defaultZone:http:localhost:8081/eureka/

 instance:     
  instanceId:application_name:${random.value}
