windows安装与启动nacos

nacos安装：https://nacos.io/zh-cn/docs/quick-start.html
下载最新的nacos，我下载的是nacos2.0.3的版本
由于nacos是基于数据库来配置系统：

运行sql，生成数据表

配置application.properties文件：

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://xxx.xxx.xxx.xxxx:3389/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=spy1679358426

运行项目：127.0.0.1:8848/nacos
