Spring cloud:服务注册 eureka 集群版
环境
- spring cloud Edgware.SR6
- jdk 7
- 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。
