新建一个项目:ms-eureka-ha-center

1.pom文件:

org.springframework.cloud
spring-cloud-starter-eureka-server

2.启动类:

package com.ljf.weifuwu.springcloud.ha.eureka;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;/** * Hello world! * */@SpringBootApplication@EnableEurekaServerpublic class EurekaHaApp{    public static void main( String[] args )    {        SpringApplication.run(EurekaHaApp.class,args);        System.out.println( "EurekaHaApp 高可用启动成功了!!!" );    }}

3.resources配置文件:

 

1.application.yml做为一个公共文件:

spring:  application:    name: ms-eureka-ha-center  profiles:    active: node1

2.application-node1.yml文件:

server:  port: 2001eureka:  instance:    hostname: node1  client:    serviceUrl:      defaultZone: http://node2:2002/eureka/,http://node3:2003/eureka/

3.application-node2.yml文件:

server:  port: 2002eureka:  instance:    hostname: node2  client:    serviceUrl:      defaultZone: http://node1:2001/eureka/,http://node3:2003/eureka/

4.application-node3.yml文件:

server:  port: 2003eureka:  instance:    hostname: node3  client:    serviceUrl:      defaultZone: http://node1:2001/eureka/,http://node2:2002/eureka/

3.不同端口的启动:

5.ip和节点名的映射:C:\Windows\System32\drivers\etc  修改host文件

6.启动访问:EurekaHaApp-node1、EurekaHaApp-node2、EurekaHaApp-node3 逐个启动,前面两个启动过程中可能会报错,可以忽略。

访问node1:

访问node2:

node3:
