**application.yml**

server:
      port: 8761
    
    #  通过eureka.client.registerWithEureka：false和fetchRegistry：false
    #  来表明自己是一个eureka server.
    eureka:
      instance:
        hostname: localhost
      client:
        registerWithEureka: false
        fetchRegistry: false
        serviceUrl:
          defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
    
    spring:
      application:
        name: eurka-server

EurekaServerApplication启动类 添加eureka的注解即可

package com.cxb.springcloud;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    
    @SpringBootApplication
    @EnableEurekaServer
    public class EurekaServerApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(EurekaServerApplication.class, args);
        }
    
    }

eurka-server服务注册中心完成。
