下载nacos 服务端jar

这边使用的是1.4.1 版本的服务包

下载地址为 https://github.com/alibaba/nacos/releases/tag/1.4.1

在windows 单机方式启动的命令为 startup.cmd -m standalone 默认点击启动文件startup.cmd是集群方式启动的，需要自己手动敲命令以单机的方式启动

启动的默认端口是8848 按默认的端口启动就可以了。

启动后，访问本地的nacos http://localhost:8848/nacos 默认登录用户密码都是 nacos

进去后可以对其修改密码，本地的密码默认应该就够了。

进去的界面如下

本地服务要是想注册进来则注册到该地址就行

搭建个父工程， springbootstudy ，建相应的moudle 工程分别为 studyuser，studyorder

公用工程 studycommon，公用工程放对应的公共类，公共的jar包

引入注册中心的配置，在 studycommon 的配置如下

</project>

studyuser的application.yml配置如下

server:
  port: 8010
spring:
  application:
    name: user-server
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
        namespace: 2a57e550-6295-4269-b1b4-268c46021020

启动 studyuser服务，启动日志如下

nacos管理界面能看到 studyuser注册上来的实例，就说明成功了

至此， nacos 的服务注册就算成功了。
