Spring Cloud 之 服务注册与发现实战

一.启动Eureka Server集群

准备三台云主机，分别开启三个Eureka服务，三个服务二二进行复制。可以准备三个application.yml配置，分别如下：

application-server1.yml

server:
  port: 8761

eureka:
  instance:
    hostname: eurekaServer1
    appname: eurekaServer1
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://eurekaServer2:${server.port}/eureka/

application-server2.yml

server:
  port: 8761

eureka:
  instance:
    hostname: eurekaServer2
    appname: eurekaServer2
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://eurekaServer3:${server.port}/eureka/

application-server3.yml  

server:
  port: 8761

eureka:
  instance:
    hostname: eurekaServer3
    appname: eurekaServer3
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://eurekaServer1:${server.port}/eureka/
