spring cloud eureka第一次部署

1.为了部署server1，server2，server3  ，需要修改在host文件新增以下

127.0.0.1 server1
127.0.0.1 server2
127.0.0.1 server3

2.application.yml如下

#spring:
#  application:
#    name: ad-eureka
#
#server:
#  port: 8000
#
#eureka:
#  instance:
#    hostname: localhost
#  client:
#    fetch-registry: false
#    register-with-eureka: false
#    service-url:
#      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

---
spring:
  application:
    name: ad-eureka
  profiles: server1
server:
  port: 8000
eureka:
  instance:
    hostname: server1
    prefer-ip-address: false
  client:
    service-url:
      defaultZone: http://server2:8001/eureka/,http://server3:8002/eureka/

---
spring:
  application:
    name: ad-eureka
  profiles: server2
server:
  port: 8001
eureka:
  instance:
    hostname: server2
    prefer-ip-address: false
  client:
    service-url:
      defaultZone: http://server1:8000/eureka/,http://server3:8002/eureka/

---
spring:
  application:
    name: ad-eureka
  profiles: server3
server:
  port: 8002
eureka:
  instance:
    hostname: server3
    prefer-ip-address: false
  client:
    service-url:
      defaultZone: http://server1:8000/eureka/,http://server2:8001/eureka/

3.进入到project所在目录，maven package 打包

4.进入ad-eureka目录，找到target目录，找到对应的jar

5.分别执行以下命令 ,期间的报错不用管（我搞这些错误几个小时）
 

java -jar ad-eureka-1.0-SNAPSHOT.jar spring.profiles.active=server1

java -jar ad-eureka-1.0-SNAPSHOT.jar spring.profiles.active=server1

java -jar ad-eureka-1.0-SNAPSHOT.jar spring.profiles.active=server1

6.浏览器访问 http://127.0.0.1:8000/

会看到如下，说明部署成功
