nginx + uwsgi + systemd 部署 flask

Flask 常用部署方式

• uWSGI + Nginx（最常用）

• Gunicorn + Nginx

• gevent.pywsgi + Nginx

使用gevent.pywsgi的完整示例：python
from gevent import pywsgi
from your_app import appserver = pywsgi.WSGIServer(('0.0.0.0', 5000), app)
print("Server running on port 5000...")
server.serve_forever()

导出第三方模块

pip freeze > requirements.txt

创建python虚拟环境

# 安装虚拟环境的第三方包 virtualenv
pip3 install virtualenv# 创建虚拟环境（虚拟环境一般放在项目根目录下）
virtualenv venv# 激活虚拟环境
source venv/bin/activate# 退出虚拟环境
deactivate

下载三方模块

在虚拟环境中导入requirements中的第三方模块

pip install -r requirements.txt

导入数据库

新建 文件 wsgi.py

# wsgi.py
from app import app  # 从应用模块导入 app 实例if __name__ == "__main__":app.run()

 创建uwsgi.ini

[uwsgi]
module = wsgi
callable = app
master = true
processes = 2
threads = 100
plugin = python3
socket = 0.0.0.0:8002# 或者使用Unix socket方式（二选一）
; socket = /myflaskapp/uwsgi.sock
; chmod-socket = 660
; vacuum = true# Python虚拟环境virtualenv = /home/ubuntu/zhiliao_oa/venv# 日志文件
logto = /home/ubuntu/zhiliao_oa/logs/error.log
buffer-size = 65535
die-on-term = true

创建 /etc/systemd/system/flaskoa.service

 配置nginx

# nginx配置server {listen   80;server_name flask.larance.xyz;location / {uwsgi_pass   127.0.0.1:8002;  # uwsgi运行的端口include uwsgi_params;}location /static{alias  /home/ubuntu/zhiliao_oa/static;  # 你收集的静态文件的位置}
}
