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/][http_127.0.0.1_8000]

会看到如下，说明部署成功
