Eureka搭建三个节点

配置文件如下：

spring:
  application:
    name: eureka
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://localhost:7900/eureka/,http://localhost:7901/eureka/,http://localhost:7902/eureka/

---
spring:
  profiles: 7900
server:
  port: 7900
eureka:
  client:
    instance:
      hostname: eureka-7900

---

spring:
  profiles: 7901
server:
  port: 7901
eureka:
  client:
    instance:
      hostname: eureka-7901
---
spring:
  profiles: 7902
server:
  port: 7902
eureka:
  client:
    instance:
      hostname: eureka-7902

启动时分别按照配置文件的端口号以及按配置文件名称启动即可，如下图：
