2.配置文件application.yml

#服务注册中心实例的主机名

spring:

  application:

    name: zl-eureka

  #节点1

  profiles: peer1

server:

  #端口

  port: 5001

eureka:

  instance:

    hostname: peer1

  client:

    #是否向服务注册中心注册自己

    registerWithEureka: true

    #是否检索服务

    fetchRegistry: true

    serviceUrl:

      #服务注册中心的配置内容，指定服务注册中心的位置

      defaultZone: http://peer2:5002/eureka/,http://peer3:5003/eureka/

---

spring:

  application:

    name: zl-eureka

  profiles: peer2

server:

  port: 5002

eureka:

  instance:

    hostname: peer2

  client:

    #是否向服务注册中心注册自己

    registerWithEureka: true

    #是否检索服务

    fetchRegistry: true

    serviceUrl:

      #服务注册中心的配置内容，指定服务注册中心的位置

      defaultZone: http://peer1:5001/eureka/,http://peer3:5003/eureka/

spring:

  application:

    name: zl-eureka

  profiles: peer3

server:

  port: 5003

eureka:

  instance:

    hostname: peer3

  client:

    #是否向服务注册中心注册自己

    registerWithEureka: true

    #是否检索服务

    fetchRegistry: true

    serviceUrl:

      #服务注册中心的配置内容，指定服务注册中心的位置

      defaultZone: http://peer1:5001/eureka/,http://peer2:5002/eureka/

3.启动类注解

@EnableEurekaServer

@SpringBootApplication

public class ZlEurekaApplication {

	public static void main(String[] args) {

		SpringApplication.run(ZlEurekaApplication.class, args);

	}

}

4.启动

首先配置hosts文件，追加以下内容：

127.0.0.1 peer1

127.0.0.1 peer2

127.0.0.1 peer3

4.1 Eclipse启动

Run Configurations中运行3次启动三个节点，profile值分别是peer1、peer2、peer3

4.2 Jar包启动

先将项目打成jar包，然后使用jar命令：

java -jar zl-eureka-0.0.1.jar --spring.profiles.active=peer1

java -jar zl-eureka-0.0.1.jar --spring.profiles.active=peer2

java -jar zl-eureka-0.0.1.jar --spring.profiles.active=peer3

4.3 war包启动
