创建注册管理中心
1.添加依赖
<!--服务注册中心 start-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
<!--服务注册中心 end-->
2.在启动程序添加注解@EnableEurekaServer
@EnableEurekaServer
@SpringBootApplication
public class ItokenEurekaApplication {
public static void main(String[] args) {
SpringApplication.run(ItokenEurekaApplication.class, args);
}
}
3.创建配置文件application.yml
spring:
application:
name: itoken-eureka
server:
port: 8761
eureka:
instance:
hostname: localhost
client:
#表示是否将自己注册到eureka,因为要构建集群,需要将自己注册到集群,所以需要开启
registerWithEureka: true
#表示是否从eureka获取到注册信息,这里为集群,所以应该开启
fetchRegistry: true
serviceUrl:
#表示从默认分区中访问eureka server,多个eureka用过逗号隔开
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/,http://${eureka.instance.hostname}:8861/eureka/
4.运行项目后,打开网址http://localhost:8761
成功即可
