Eureka server和eureka client分开tomcat台服务器

Question

我正在寻找一种能够将 Eureka 服务器部署到不同于 Eureka 客户端的 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

并且服务器 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，它工作得很好。但是，如果我仅使用服务器启动 tomcat，然后使用客户端启动服务器，我会收到以下错误：

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 服务器位置的信息 running.client 应该向 eureka 服务器注册，为此您需要配置您的客户application.yml如下

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

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

Eureka server和eureka client分开tomcat台服务器

Eureka server and eureka client to separate tomcat servers

spring
