Eureka Server集羣

1.開啓註解:

@SpringBootApplication
@EnableEurekaServer
public class SpringCloudEurekaApplication {

	public static void main(String[] args) {
		SpringApplication.run(SpringCloudEurekaApplication.class, args);
	}
}

2.application.yml

---
spring:
  application:
    name: spring-cloud-eureka
  profiles: peer1
server:
  port: 8001
eureka:
  instance:
    hostname: peer1
  client:
    serviceUrl:
      defaultZone: http://peer2:8002/eureka/,http://peer3:8003/eureka/
---
spring:
  application:
    name: spring-cloud-eureka
  profiles: peer2
server:
  port: 8002
eureka:
  instance:
    hostname: peer2
  client:
    serviceUrl:
      defaultZone: http://peer1:8001/eureka/,http://peer3:8003/eureka/
---
spring:
  application:
    name: spring-cloud-eureka
  profiles: peer3
server:
  port: 8003
eureka:
  instance:
    hostname: peer3
  client:
    serviceUrl:
      defaultZone: http://peer1:8001/eureka/,http://peer2:8002/eureka/

3. IDEA的run configration中通過配置

 

第一個cluster-peer1：

main class：com.neo.SpringCloudEurekaApplication

program arguments： --spring.profiles.active=peer1

選中 allow parrallel run。

第二個cluster-peer2：

main class：com.neo.SpringCloudEurekaApplication

program arguments： --spring.profiles.active=peer2

選中 allow parrallel run。

 

第三個cluster-peer3：

main class：com.neo.SpringCloudEurekaApplication

program arguments： --spring.profiles.active=peer3

選中 allow parrallel run。

4. hosts文件增加配置

127.0.0.1  peer1  
127.0.0.1  peer2
127.0.0.1  peer3

5. 啓動cluster-peer1、cluster-peer2、cluster-peer3
