編寫啓動類
@EnableEurekaServer註解聲明這是一個Eureka Server

package com.etoak;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class App {
	public static void main(String[] args) {
		SpringApplication.run(App.class, args);
	}
}

添加配置文件application.yml

server:
  port: 7777
eureka:
   client:
     registerWirhEureka: false  #是否將自己註冊到Eureka Server，默認爲true，由於當前應用就是Eureka Server，故而設爲false
     fetchRegistry: false       #是否從Eureka Server獲取註冊信息，默認爲true，因爲這是一個單點的Eureka Server，不需要同步其他的Eureka Server節點數據，故而設爲false
     serviceUrl:
       defaultZone: http://localhost:7777/eureka/  #設置與Eureka Server交互的地址，查詢服務和註冊都需要依賴這個地址

登錄http://localhost:7777/出現以下頁面成功

附：出現Cannot execute request on any known server錯誤，請詳細檢查配置文件
