X-Forwarded-Proto and Flask

由 瘦欲@ 提交于 2019-12-18 03:52:20
问题 I have precisely the same problem described in this SO question and answer. The answer to that question is a nice work around but I don't understand the fundamental problem. Terminating SSL at the load balancer and using HTTP between the load balancer and web/app servers is very common. What piece of the stack is not respecting the X-Forwarded-Proto? Is it werkzeug? Flask? uwsgi? In my case I'm using an AWS ELB (which sets X-Forwarded-Proto) => Nginx (which forwards along X-Forwarded-Proto to

问题 I'm using ubuntu 13.04. I'm running uwsgi using sudo service uwsgi start I've configured log file in django as /home/shwetanka/logs/mysite/mysite.log But I'm getting this error - ValueError: Unable to configure handler 'file': [Errno 13] Permission denied: '/home/shwetanka/logs/mysite/mysite.log' How do I fix it? This should not happen when I run uwsgi as sudo. 回答1: You need to fix permissions with the chmod command, like this: chmod 775 /home/shwetanka/logs/mysite/mysite.log . Take a look at

Django +uwsgi+python3+nginx + mysql 部署

环境： 服务器ip：192.168.0.110 centos服务器 6.4 + mysql 5.6 + django1.11 +nginx 1.13.7 + uwsgi 2.0.18 uwsgi介绍 uWSGI是一个Web服务器，它实现了WSGI协议、uwsgi、http等协议。Nginx中HttpUwsgiModule的作用是与uWSGI服务器进行交换。 要注意 WSGI / uwsgi / uWSGI 这三个概念的区分。 WSGI是一种Web服务器网关接口。它是一个Web服务器（如nginx，uWSGI等服务器）与web应用（如用Flask框架写的程序）通信的一种规范。 uwsgi是一种线路协议而不是通信协议，在此常用于在uWSGI服务器与其他网络服务器的数据通信。 而uWSGI是实现了uwsgi和WSGI两种协议的Web服务器。 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（type of information），每一个uwsgi packet前4byte为传输信息类型描述，它与WSGI相比是两样东西。 uWSGI的主要特点如下 超快的性能 低内存占用 多app管理 详尽的日志功能 高度可定制（内存大小限制，服务一定次数后重启等） nginx+uwsgi 工作原理： 　　nginx负责建立一个本地的工作环境，就是本地服务器，类似于pycharm的

How to set up autoreload with Flask+uWSGI?

由 ぐ巨炮叔叔 提交于 2019-12-17 23:20:36
问题 I am looking for something like uWSGI + django autoreload mode for Flask. 回答1: You could try using supervisord as a manager for your Uwsgi app. It also has a watch function that auto-reloads a process when a file or folder has been "touched"/modified. You will find a nice tutorial here: Flask+NginX+Uwsgi+Supervisord 回答2: I am running uwsgi version 1.9.5 and the option uwsgi --py-autoreload 1 works great 回答3: If you're configuring uwsgi with command arguments, pass --py-autoreload=1 : uwsgi -

Non-blocking concurrent wsgi server

由 核能气质少年 提交于 2019-12-17 19:52:06
问题 I am trying to be able to respond incoming web requests simultaneously, while processing of a request includes quite long IO call. I'm going to use gevent, as it's supposed to be "non-blocking" The problem I found is that requests are processed sequentially even though I have a lot of gevent threads. For some reason requests get served by single green thread. I have nginx (with default config which isn't relevant here I think), also I have uwsgi and simple wsgi app that emulates IO-blocking

问题 I am getting this error in my nginx-error.log file: 2014/02/17 03:42:20 [crit] 5455#0: *1 connect() to unix:/tmp/uwsgi.sock failed (13: Permission denied) while connecting to upstream, client: xx.xx.x.xxx, server: localhost, request: "GET /users HTTP/1.1", upstream: "uwsgi://unix:/tmp/uwsgi.sock:", host: "EC2.amazonaws.com" The browser also shows a 502 Bad Gateway Error. The output of a curl is the same, Bad Gateway html I've tried to fix it by changing permissions for /tmp/uwsgi.sock to 777.
