搭建Eureka注册中心

先创建一个maven项目

导入springboot springcloud和Eureka相关依赖

依赖这里一直有错误，改了半天才可以用 ，用的是阿里云的仓库下载的。

resources下的application.yml 文件

#服务端口号
server: 
  port: 8100
eureka: 
  instance: 
  #注册中心ip
    hostname: 127.0.0.1
  client: 
    serviceUrl: 
    #注册地址
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
    #是否需要把吧本项目注册到注册中心
    register-with-eureka: false
    #因为自己是注册中心 所以不需要检索服务
    fetch-registry: false

然后写一个启动类

 
package com.vhukze.app;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
 
/**
* @author zsz
* @version 
* @创建时间：2019年10月9日 上午8:52:42
*/
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
@EnableEurekaServer
public class EurekaApp {
 
	//@EnableEurekaServer表示开启服务 开启注册中心
	
	public static void main(String[] args) {
		SpringApplication.run(EurekaApp.class, args);
	}
}

启动项目访问localhost:8100

现在是还没有提供者 所以这里是空的
