Server yml配置

###eureka 服务端口号
server:
  port: 9100
###服务注册名称
eureka:
  instance:
    hostname: 127.0.0.1
  ###客户端调用地址
  client:
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:8100/eureka/
    ###因为该应用为注册中心，不会注册自己
    register-with-eureka: true
    ###因为自己为注册中心 ,不会去在该应用中的检测服务
    fetch-registry: true
  server:
    #测试关闭自我保护机制保证 不可用服务及时提出
    enable-self-preservation: false
    eviction-interval-timer-in-ms: 2000
spring:
  application:
    name: app-clear-eureka

注意保护机制的配置，在生产环境下建议关闭自我保护机制。但是在线上环境要打开

Client yml配置

###eureka 服务端口号
server:
  port: 8200
###服务注册名称
eureka:
  instance:
    hostname: 127.0.0.1
    ##配置心跳时间间隔  
    lease-renewal-interval-in-seconds: 1
    ##配置服务端心跳等待时间上线，两秒内没收到则剔除这个服务
    lease-expiration-duration-in-seconds: 2
  ###客户端调用地址

  client:
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:8100/eureka/,http://${eureka.instance.hostname}:9100/eureka/
    ###因为该应用为注册中心，不会注册自己
    register-with-eureka: true
    ###检测应用中的服务
    fetch-registry: true
spring:
  application:
    name: app-clear-order

注意zk版本关系

yml配置

###订单服务的端口号
server:
  port: 8002
###服务别名----服务注册到注册中心名称
spring:
  application:
    name: zk-member
  cloud:
    zookeeper:
      connect-string: 127.0.0.1:2181

consul配置

启动consul命

consul agent -dev -ui -node=cy

-dev开发服务器模式启动，-node结点名为cy，-ui可以用界面访问，默认能访问。

测试访问地址:http://localhost:8500
