Flask 应用如何部署

文章目录 Flask 应用如何部署 1. Why Flask+Gunicorn+Nginx 1.1 Why? 1.2 Anything More? 2. Flask网站如何部署 2.1 Gunicorn 2.2 Nginx 3. 基于Docker的Flask网站部署 3.1 构建Flask网站的镜像 3.2 Nginx 相关的配置 3.3 用Docker-compose编排服务 4. 其他Python web网站的部署 Flask 应用如何部署 1. Why Flask+Gunicorn+Nginx Flask+Gunicorn+Nginx是最常用的Flask部署方案，大家深究过为何用这样的搭配么？ 1.1 Why? Flask 是一个web框架，而非web server，直接用Flask拉起的web服务仅限于开发环境使用，生产环境不够稳定，也无法承受大量请求的并发，在生茶环境下需要使用服务器软件来处理各种请求，如Gunicorn、 Nginx或Apache，而Gunicorn+Nginx的搭配，好处多多，一方面基于Nginx转发Gunicorn服务，在生产环境下能补充Gunicorn服务在某些情况下的不足，另一方面，如果做一个Web网站，除了服务外，还有很多静态文件需要被托管，这是Nginx的强项，也是Gunicorn不适合做的事情。所以，基于Flask开发的网站

How do I handle interleaved exceptions from different Gunicorn forks?

由 我们两清 提交于 2019-12-13 18:16:15
问题 I have a Flask app running in a forked Gunicorn environment, but the stacktraces are getting interleaved in the logfile. Can each fork have its own logfile? or can each logger have exclusive access while writing to the log? 回答1: Can each fork have its own logfile? Yes, although you probably don't need, or want, that. The easiest way to do this is to just stick os.getpid() somewhere in the filename. or can each logger have exclusive access while writing to the log? There are a few ways to do

问题 I'm running a Django 1.8 project on a DigitalOcean VPS (512 MB RAM, 1 CPU, 20GB SSD). I have Nginx proxying traffic to gunicorn. Here is my gunicorn command (run via supervisor): gunicorn my_web_app.wsgi:application --worker-class gevent --bind 127.0.0.1:8001 --timeout=1200 I noticed that when I upload a ~3-5 MB image to my web app, the gunicorn worker crashes with this error: Jan 16 12:39:46 dev-1 kernel: [663264.917312] Out of memory: Kill process 31093 (gunicorn) score 589 or sacrifice

Heroku deployment using django and gunicorn: Missing gunicorn_django file or dir

由 ☆樱花仙子☆ 提交于 2019-12-13 00:59:47
问题 This blog advises to put the following in my Procfile . web: python myproject_django/manage.py collectstatic --noinput; bin/gunicorn_django --workers=4 --bind=0.0.0.0:$PORT myproject_django/settings.py But running my project on Heroku fails. This is from $ Heroku logs : app[web.1]: bash: bin/gunicorn_django: No such file or directory So there is a gunicorn_django file/dir missing. What should that file/dir contain and where should I put it? Tree . ├── Procfile ├── myproject_django │ ├── admin

How to restart Foreman when code in a Django site changes?

由 自古美人都是妖i 提交于 2019-12-12 22:30:50
问题 I'm running a Django website in a Vagrant box that (roughly) mirrors a Heroku set-up. It uses Foreman with a Procfile like this: web: gunicorn projectname.wsgi > /vagrant/gunicorn.log 2>&1 However, when I change my Django code, the server doesn't restart or reload the code, which makes development... painful! How can I make Foreman serve the new code when it changes? 来源： https://stackoverflow.com/questions/38189188/how-to-restart-foreman-when-code-in-a-django-site-changes
