springCloud-1.搭建Eureka Server項目並啓動

1.使用IDEA，Spring Initializr建立

 

2.填寫項目資料

 

3.選擇spring boot版本，插件選擇Cloud Discovery→Eureka Server

 

4.選擇保存地址

 

5.pom文件

<?xml version="1.0" encoding="UTF-8"?>

</project>

 

6.修改application.yml

server:
  port: 8761

eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

spring:
  application:
    name: eurka-server

    備註：在默認狀況下erureka server也是一個eureka client

    經過eureka.client.registerWithEureka：false和fetchRegistry：false來代表本身是一個eureka server

 

7.啓動文件添加@EnableEurekaServer註解

package com.test.eurekaserver;

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);
    }
}

 

8.去掉勾選

 

9.啓動項目

    備註：若是出現方法或類找不到，請clean

 

10.eurka-server是必須爲了不麻煩咱們後臺啓動eurka-server

        1.install  打成jar包

        

        2.打開終端進入target文件夾      

        3.啓動  java -jar eureka-server-0.0.1-SNAPSHOT.jar

            結束運行：Ctrl+C

           備註：若是端口被佔用

            

            1.ps -e | grep eureka        

            2.kill -9 1410（進程ID）

        4.後臺啓動：nohup java -jar eureka-server-0.0.1-SNAPSHOT.jar /dev/null 2>&1 &

           結束運行：ps -e | grep eureka    kill -9 (進程ID)
