一、前言献给和我一样懵懂中不断汲取知识，进步的人们。霓虹闪烁，但人们真正需要的，只是一个可以照亮前路的烛光二、必要的前提 2.1 准备知识 1.django 一个基于python的开源web框架，请确保自己熟悉它的框架目录结构。 2.uWSGI 一个基于自有的uwsgi协议、wsgi协议和http服务协议的web网关 3.nginx 常用高性能代理服务器 4.wsgi.py django项目携带的一个wsgi接口文件如果项目名叫destiny的话，此文件就位于[destiny/destiny/wsgi.py] 2.2 相关资料 wsgi：一种实现python解析的通用接口标准/协议，是一种通用的接口标准或者接口协议，实现了python web程序与服务器之间交互的通用性。利用它，web.py或bottle或者django等等的python web开发框架，就可以轻松地部署在不同的web server上了； uwsgi:同WSGI一样是一种通信协议 uwsgi协议是一个uWSGI服务器自有的协议，它用于定义传输信息的类型，它与WSGI相比是两样东西。 uWSGI :一种python web server或称为Server/Gateway uWSGI类似tornadoweb或者flup，是一种python web server

debugging a uwsgi python application using pycharm

阅读更多关于 debugging a uwsgi python application using pycharm

问题 Is it possible to debug a uwsgi application using an ide like PyCharm? I can debug flask based apps fine by running them directly from pycharm but cannot even run a uwsgi app from within pycharm. Do I have to use remote debugging? Is it possible to start a uwsgi app from within pycharm using run? 回答1: You can still run your WSGI app outside of uWSGI for development and debugging purposes. However sometimes this is not possible, for example if your app relies on uWSGI API features. As far as I

Apscheduler is executing job multiple times

阅读更多关于 Apscheduler is executing job multiple times

问题 I have a django application running with uwsgi (with 10 workers) + ngnix. I am using apscheduler for scheduling purpose. Whenever i schedule a job it is being executed multiple times. From these answers ans1, ans2 i got to know this is because the scheduler is started in each worker of uwsgi. I did conditional initializing of the scheduler by binding it to a socket as suggested in this answer and also by keeping a status in the db, so that only one instance of scheduler will be started, but

Is uwsgi protocol faster than http protocol?

阅读更多关于 Is uwsgi protocol faster than http protocol?

问题 I am experimenting with various setups for deploying django apps. My first choice was using a simple apache server with mod_wsgi, which I had implemented before for private use. Since the current deployment is for public use, I am looking at various options. Based on the information available online, it seems it is good to have nginx for serving static content as well as a reverse proxy for a dynamic content server. Now given my previous knowledge of Apache I was considering using the same

uwsgi does not reload after changing django settings

阅读更多关于 uwsgi does not reload after changing django settings

问题 I have set up uwsgi to serve django behind nginx. Then I change the database in django settings but uwsgi still shows the site with old database. I also tried this suggestion and added touch-reload = /etc/uwsgi/apps-available/django.ini to the ini file. But after restarting uwsgi and touching django.ini it still serves the old site. I tried to deactivate and reactivate virtualenv, no chance either. So really got confused and appreciate your hints. 回答1: From uWSGI docs about touch-reload:

Server-Sent Events with Nginx and uWSGI

阅读更多关于 Server-Sent Events with Nginx and uWSGI

问题 Is it possible to use server-sent events from a python/Flask application that is behind uWSGI and Nginx? I've found packages that implement SSE in python/Flask, but they seem to all do so using gevent and greenlets. https://github.com/DazWorrall/flask-sse Thanks! 回答1: can't you simply use gevent with uWSGI ? Generally this kind of technologies should be used with async engines as the multithread/multiprocess paradigm would be too much costly. 回答2: Recent versions of uWSGI (from 1.9) have

问题 So I'm trying to use uwsgi behind apache2, but I am doing so on a CentOS 6 machine. (I'm use to Debian/Ubuntu based systems for context.) I used pip install uwsgi and followed the directions for launching uwsgi with a Django application (via http://uwsgi-docs.readthedocs.org/en/latest/WSGIquickstart.html). I started to configure apache2 as per http://uwsgi-docs.readthedocs.org/en/latest/Apache.html, but it says nothing about where to get or how to build mod_uwsgi or mod_proxy_uwsgi. mod_uwsgi

问题 I want to run Django with uWSGI behind a NGINX. I will use Django as a API service which should live on this link: project.test/api The Django project itself is blank (1.9.6), just created a app, migrated and created a superuser. My Project structure looks like this: /vagrant/api/here-lives-whole-django /vagrant/api/uwsgi_params /vagrant/frontend/some-frontend-work-seperated-from-django My NGINX setup looks like this: upstream testing { server 127.0.0.1:8000; } server { listen 80; server_name
