部署前的环境配置：
安装宝塔面板镜像，开通8888端口和22端口，以及项目部署的端口，
例如：
1/15666开放1至15666所有端口，这样可以为以后其他端口开放提供便利。
登录宝塔面板，效果如下
将node项目上传至www/wwwroot 文件夹
在软件商店下载pm2node 进程管理器
下载对应模块和对应node版本号
然后添加mysql数据库，上传sql,并且导入，
完成后点击管理查看效果，如下
更改node 项目mysql的账号和密码
添加node进程
添加成功显示
如果端口号为off, 则表示添加不成功，原因可能为：
1、端口被占用，
2、端口为打开，需要配置安全组
3、数据库连接失败
4、项目逻辑有问题，报错
需要耐心去解决，直至端口号为你项目运行的端口号
进程添加成功后，在宝塔面板安全中心栏，放行3006
接下来就可以通过IP+ 端口访问接口了,效果如下
