1.pom文件添加依赖

<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>

2.使用@EnableEurekaServer注解

@SpringBootApplication
@EnableEurekaServer
public class Application {

    public static void main(String[] args) {
        new SpringApplicationBuilder(Application.class).web(true).run(args);
    }

}

3.配置application.yml 独立模式

server:
  port: 8761

eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

4.配置application.yml 对等模式

---
spring:
  profiles: peer1
eureka:
  instance:
    hostname: peer1
  client:
    serviceUrl:
      defaultZone: http://peer2/eureka/

---
spring:
  profiles: peer2
eureka:
  instance:
    hostname: peer2
  client:
    serviceUrl:
      defaultZone: http://peer1/eureka/

5.高可用模式

eureka:
  client:
    serviceUrl:
      defaultZone: http://peer1/eureka/,http://peer2/eureka/,http://peer3/eureka/

---
spring:
  profiles: peer1
eureka:
  instance:
    hostname: peer1

---
spring:
  profiles: peer2
eureka:
  instance:
    hostname: peer2

---
spring:
  profiles: peer3
eureka:
  instance:
    hostname: peer3

6.首选ip地址 Prefer IP Address

eureka:
  instance:
    prefer-ip-address: true

7.访问

http://localhost:8761

8.注册地址

http://localhost:8761/eureka/

9.启动脚本

java -jar eureka.jar 

java -jar eureka.jar --spring.profiles.active=peer1
java -jar eureka.jar --spring.profiles.active=peer2

java -jar eureka.jar --spring.profiles.active=eureka0
java -jar eureka.jar --spring.profiles.active=eureka1
java -jar eureka.jar --spring.profiles.active=eureka2
