1. 安装环境配置

白嫖了阿里云的学生计划服务器：https://developer.aliyun.com/plan/student
这个只要用支付宝认证学生就可以直接获得1个月的免费云服务器，然后完成一个非常简单的课程与考试就能再获得6个月的。
先按照这个教程开一下远程登录服务器的账号和密码：通过密码或密钥认证登录Linux实例
根据这个教程（Linux系统实例快速入门）的步骤2和4设置开一下端口和Apache服务
我个人习惯用VSCode，所以我就是用VSCode连的。可以用ssh，也可以用账号密码直接登录root账号
然后开一个新的用户账号：
useradd user_name
设置密码
之所以不能直接用root，是因为Apache不能用root账号，否则会报错：Error:\tApache has not been designed to serve pages while\n\trunning as root. There are known race conditions that\n\twill allow any local user to read any file on the system.\n\tIf you still desire to serve pages as root then\n\tadd -DBIG_SECURITY_HOLE to the CFLAGS env variable\n\tand then rebuild the server.\n\tIt is strongly suggested that you instead modify the User\n\tdirective in your httpd.conf file to list a non-root\n\tuser.\n
用新账号进/home/user_name，新建虚拟环境：

pip3 install --user pipx
python -m pipx install virtualenv
python -m pipx ensurepath
cd 放包的路径
virtualenv venv_name

安装所需要的工具包：

pip install flask
yum -y install httpd-devel
sudo yum makecache
pip install mod_wsgi
pip install pytz
pip install requests
yum install tmux

配置Apache端口转发（但这玩意得有域名了才用得上，但我的域名还没有备案）：Apache如何配置端口转发_linux 的 apache 如何端口跳转_Leon Jens的博客-CSDN博客 apache 80端口转发 - 掘金 apache配置端口转发的具体方法-Apache-PHP中文网配置文件(httpd.conf)的路径及辅助配置文件的读取 | Apache Apache配置文件httpd.conf详解 - 简书 CentOS 7 Apache httpd 管理 - 阿笨哥

2. 前后台代码编写

测试时直接运行get_input.py，正式上线时在tmux中挂起mod_wsgi-express start-server wsgi.py --processes 4
（如果想调整端口，设置port参数¹）
