一.安装并创建虚拟环境 #取消虚拟环境：deactivate
1.安装virtualenv
pip3.9 install virtualenv

2.创建具体的虚拟环境实例
virtualenv /envs/demo2 –python=python3.9

3.激活虚拟环境
source /envs/demo2/bin/activate 这是linux环境下

\envs\demo2\bin\activate 这是windows环境下

#退出虚拟环境 deactivate

二.创建项目
django-admin startproject demo2

3.安装uwsgi
pip install uwsgi

uwsgi –http :8002 –wsgi-file helloworld.py #如果使用了虚拟环境，这个命令一定要在激活了对应的虚拟环境的状态下执行，不然启用的就是系统环境下的uwsgi

直接运行项目：python manage.py runserver 0.0.0.0:8002

具体案例：

项目目录结构：

day16/
├── .idea/
├── app01/
├── day16/
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   ├── wsgi.py
│   └── ...
├── manage.py
├── Monaco.ttf
├── requirements.txt
└── ╩╣╙├modelform╓«╟░╡─app01/

使用心得

1.启动uwsgi –ini uwsgi.ini #此处ini前面是两条短横线，但是显示的是一条，前端展示问题 

2.结束所有uwsgi进程 pkill -9 uwsgi

3.查找所有uwsgi进程 ps aux | grep uwsgi

4.如果需要用一个指定的端口号，记得在平台的安全组中放行此端口

5.如果出现502 Bad Gateway，记得去nginx的error.log和uwsgi的log日志中查看是什么报错
PS：我遇到的是诸如权限的问题，利用chatgpt，大致可以解决
