1,创建一个maven项目springcloud_eureka

2,导入pom依赖

            <artifactId>spring-cloud-starter-eureka-server</artifactId>

            <!-- 资源文件拷贝插件 -->

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

3,创建application.yml文件,里面配置相应的信息

# 自己的服务端口
server:
  port: 6868 #服务端口

eureka:
  client:
    registerWithEureka: false #是否将自己注册到Eureka服务中，本身就是所有无需注册
    fetchRegistry: false  #是否从Eureka中获取注册信息
    serviceUrl:    #Eureka客户端与Eureka服务端进行交互的地址
      defaultZone: http://127.0.0.1:${server.port}/eureka/

# 开启安全监测     
security: 
  basic:  
    enable: true #开启基于HTTP basic的认证
  user: #配置用户的账号信息
    name: shawemou
    password: shawemou   

4,配置spring_eureka的入口类EurekaSpringAppplication

@EnableEurekaServer
@SpringBootApplication
public class EurekaSpringAppplication {

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

5,访问eureka服务
