springCloud搭建分布式微服务学习--3--eureka的集群搭建步骤

1新增eureka的第二个模块
2在c://window//system32//etc的hosts文件中新增如下:

3改两个或三个的eureka模块的yml,进行互相注册:

server:
  port: 7002

eureka:
  instance:
    hostname: eureka7002.com #eureka服务端的实例名称
  client:
    #这里必须要写true,否则不能互相注册,大坑
    register-with-eureka: true
    
    fetch-registry: true
    service-url:
      #设置与Eureka Server交互的地址查询服务和注册服务都需要依赖这个地址,互相注册
      defaultZone: http://eureka7001.com:7001/eureka/

4在服务端和客户端中修改yml:

server:
  port: 80
eureka:
  client:
    fetch-registry: true
    register-with-eureka: true
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka
spring:
  application:
    name: order80
