Python Web 程序使用 uWSGI 部署

Python Web 程序使用 uWSGI 部署 WSGI是什么? WSGI,全称 Web Server Gateway Interface,或者 Python Web Server Gateway Interface ,是为 Python 语言定义的 Web 服务器和 Web 应用程序或框架之间的一种简单而通用的接口。自从 WSGI 被开发出来以后,许多其它语言中也出现了类似接口。 WSGI 的官方定义是,the Python Web Server Gateway Interface。从名字就可以看出来,这东西是一个Gateway,也就是网关。网关的作用就是在协议之间进行转换。 WSGI 是作为 Web 服务器与 Web 应用程序或应用框架之间的一种低级别的接口,以提升可移植 Web 应用开发的共同点。WSGI 是基于现存的 CGI 标准而设计的。 很多框架都自带了 WSGI server ,比如 Flask,webpy,Django、CherryPy等等。当然性能都不好,自带的 web server 更多的是测试用途,发布时则使用生产环境的 WSGI server或者是联合 nginx 做 uwsgi 。也就是说,WSGI就像是一座桥梁,一边连着web服务器(如 nginx),另一边连着Python的应用程序Application。但是呢,这个桥的功能很弱

Apscheduler is executing job multiple times

邮差的信 提交于 2019-12-03 04:01:14
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 still the same problem exists and also sometimes when creating a job the scheduler is found not running

Difference between uwsgi_pass and proxy_pass in Nginx?

假如想象 提交于 2019-12-03 03:10:14
问题 I'm running uWSGI behind Nginx and have been using proxy_pass to get Nginx to hit uWSGI. Is there any benefit to switch to uwsgi_pass . If so, what is it? 回答1: uwsgi_pass uses an uwsgi protocol. proxy_pass uses normal HTTP to contact with uWSGI server. uWSGI docs claims that this protocol is better, faster and can benefit from all of uWSGI special features. Are there any real benefits? Yes. You can send to uWSGI information what type of data you are sending and what uWSGI plugin should be

I have basically the default configurations on everything. I have a Python client sending 3 requests per second to that server. The Problem After running the client for about 4 hours, the

Use anaconda environment without activate? (e.g. in Crontab)

a 夏天 提交于 2019-12-03 02:49:07
Being reading this http://conda.pydata.org/docs/using/envs.html Is it possible to run a conda python directly without having to source activate xxx ? In VirtualEnv, you can find the exact location of the python executable and run something like this ./path/to/my/venv/bin/python xxx.py Then xxx.py will be executed with environment on. It's handy to write one-linders in Crontab. Could I do the same with anaconda/miniconda environments? I've been trying this on Centos 6.5, system has python 2.5 which is too old. I installed python 2.7 with miniconda, now I pip installed uWSGI, when executing it
