Spring cloud:服务注册 eureka 集群版

环境

  1. spring cloud Edgware.SR6
  2. jdk 7
  3. sts 4.6.0

背景

实现一个服务注册组件 eureka 集群版。由于在一台电脑上启动,所以使用不同的端口,端口分配为 8761,8762 和 8763。

搭建步骤

pom.xml 不需要新增依赖。

hosts 增加映射

由于使用域名进行访问,所以在 hosts 中进行配置,增加如下的内容:

127.0.0.1 eureka1
127.0.0.1 eureka2
127.0.0.1 eureka3

第一个节点

application.yml:

server:
  port: 8761

spring:
  application:
    name: eureka

eureka:
  instance:
    hostname: eureka1
  client:
    serviceUrl:
      defaultZone: http://eureka1:8761/eureka/,http://eureka2:8762/eureka/,http://eureka3:8763/eureka/

第二个节点

application.yml:

server:
  port: 8762

spring:
  application:
    name: eureka

eureka:
  instance:
    hostname: eureka2
  client:
    serviceUrl:
      defaultZone: http://eureka1:8761/eureka/,http://eureka2:8762/eureka/,http://eureka3:8763/eureka/

第三个节点

application.yml:

server:
  port: 8763

spring:
  application:
    name: eureka

eureka:
  instance:
    hostname: eureka3
  client:
    serviceUrl:
      defaultZone: http://eureka1:8761/eureka/,http://eureka2:8762/eureka/,http://eureka3:8763/eureka/

启动项目

直接使用 main 方法启动三个项目。

package jiangbo.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class JiangBoApplication {

    public static void main(String[] args) {

        SpringApplication.run(JiangBoApplication.class, args);
    }
}

验证结果

分别访问 localhost:8761 localhost:8762 localhost:8762 看看能否看到 eureka 的界面,并且能看到集群信息。
