flask-project-demo

环境准备

python3 -m venv venv
# mac
. venv/bin/activate
# windows
venv\Scripts\activate

pip install Flask

创建文件gitignore 创建文件夹flaskr, tests

# windows, development表示修改代码不用重启,还开启了调试模式(页面显示错误)
set FLASK_APP=flaskr
set FLASK_ENV=development

# linux
export FLASK_APP=flaskr
export FLASK_ENV=development

flask init-db
# 默认监听127.0.0.1
flask run
# 监听所有网络
flask run --host=0.0.0.0

测试

pytest -s 测试的是已经install的app

打包和安装

安装打包依赖 pip install wheel

生成安装文件(在dist下) python setup.py bdist_wheel

安装 pip3 install flaskr-1.0.0-py3-none-any.whl

部署运行

export FLASK_APP=flaskr 首先得通过flask进行数据库初始化 db_path: /usr/local/python3.7/var/flaskr-instance/flaskr.sqlite

centos 加python3 -m python3 -m flask init-db

pip3 install waitress mac: waitress-serve --call 'flaskr:create_app' windows: waitress-serve --call flaskr:create_app centos: python3 -m waitress --port=5000 --call flaskr:create_app

问题: pip install uwsgi 之后,运行uwsgi 报错:[uwsgi: command not found]

**解决方案:**建立软链接 ln -s /usr/local/python3.7/bin/uwsgi /usr/bin/uwsgi
