flask项目部署到云服务器，并通过域名访问后端服务

本篇介绍一下如何把flask项目部署到腾讯云服务器，同时使用域名来访问后端服务

在之前一篇文章中写了一下如何在flask中配置https请求

1、把代码打包上传到服务器

上传至服务器前，需要修改一下启动ip

我的项目启动文件为run_main.py

from data_factory import create_app

app = create_app()

if __name__ == '__main__':
    # app.run(debug=True, host='0.0.0.0', port=5000)
    app.run(debug=True, host='10.xxx.xxx.xxx', port=5000, ssl_context=('7784675_bingshuang.top.pem','7784675_bingshuang.top.key'))

因为要部署到云服务器，所以host需要改为云服务器地址

注意这里不要改为公网ip，要填写内网ip！！

然后把代码上传到服务器，如下

2、域名设置

给域名配置ip地址，这里需要写入服务器的公网ip

3、启动项目

在云服务器中启动flask项目，命令如下

# 首先进入项目目录,然后运行run_main.py
[root@VM-8-3-centos flaskProject]# cd /app/flaskProject/
[root@VM-8-3-centos flaskProject]# python3 run_main.py
