Terminating a uwsgi worker programmatically

独自空忆成欢 提交于 2020-01-16 20:10:12
问题 In my application I need to "simulate" a HTTP timeout. Simply put, in this scenario: client -> myapp -> server client makes a HTTP POST connection to myapp which forwards it to server . However, server does not respond due to network issues or similar problems. I am stuck with an open TCP session from client which I'll need to drop. My application uses web.py, nginx and uwsgi. I cannot return a custom HTTP error such as 418 I am a teapot - it has to be a connection timeout to mirror server 's

nginx+uWSGI+django+virtualenv+supervisor发布web服务器

你说的曾经没有我的故事 提交于 2020-01-14 15:57:26
nginx+uWSGI+django+virtualenv+supervisor发布web服务器 导论 WSGI是Web服务器网关接口。它是一个规范,描述了Web服务器如何与Web应用程序通信,以及Web应用程序如何链接在一起以处理一个请求,(接收请求,处理请求,响应请求) 基于wsgi运行的框架有Bottle,Django,Flask,用于解析动态HTTP请求 支持WSGI的服务器 wsgiref python自带的web服务器 Gunicorn 用于linux的 python wsgi Http服务器,常用于各种django,flask结合部署服务器。 mode_wsgi 实现了Apache与wsgi应用程序的结合 uWSGI C语言开发,快速,自我修复,开发人员友好的WSGI服务器,用于Python Web应用程序的专业部署和开发。 在部署python程序web应用程序时,可以根据性能的需求,选择合适的wsgi server,不同的wsgi server区别在于并发支持上,有单线程,多进程,多线程,协程的区别,其功能还是近似,无非是请求路由,执行对应的函数,返回处理结果。 Django部署 Django的主要部署平台是 WSGI,这是用于Web服务器和应用程序的Python标准。 Django的 startproject管理命令设置一个简单的默认WSGI配置

部署你的CRM程序

部署你的CRM程序 发布CRM你将使用以下软件 nginx uWSGI CentOS7 CRM项目文件 virtualenv supervisor WSGI、uWSGI python web服务器开发使用WSGI协议(Web Server Gateway Interface) python web项目默认会生成一个wsgi.py文件,确定好应用模块。 生产环境中使用的是uWSGI,实现了WSGI所有接口,C语言编写,效率很高的web服务器。 uWSGI是一个全功能的HTTP服务器,实现了WSGI协议、uwsgi协议、http协议等。它要做的就是把HTTP协议转化成语言支持的网络协议。比如把HTTP协议转化成WSGI协议,让Python可以直接使用。 Nginx 使用nginx是为了它的反向代理功能,项目会通过Django+uWSGI+Nginx进行服务器线上部署。 CentOS 1.打包项目CRM文件夹,压缩文件 2.通过xftp、scp、lrzsz等上传文件至Centos服务器 Linux使用技巧 1.通过xshell或者iTerm等软件,多终端操作你的linxu,这样对uwsgi、nginx、项目代码调试的时候,避免来回切换目录,提供工作效率。 2.注意修改了linux软件的配置文件,都要重启服务才能生效。 Virtualenv 构建一个干净,隔离的python解释器环境

uwsgi + Django REST framework: few slow request after idle time

微笑、不失礼 提交于 2020-01-13 14:04:41
问题 I'm running Django REST framework with fairly low request per minute rate during the day. I've noticed one problem that I could't explain or reproduce. Every day, during the night or early in the morning, when my RPM is close to zero I have 1 - 10 requests that are super slow. Average response time for me us between 100 and 200 ms , but this ones are from 50s to 1 minute . On this screen you can see how it happens: As my primary database I'm using MySQL and I've implemented logging for each

centos7 配置 uwsgi 系统服务(systemd)开机自启

放肆的年华 提交于 2020-01-13 01:56:16
背景生产环境中采用 nginx + uwsgi + django 来部署web服务,这里需要实现uwsgi的启动和停止,简单的处理方式可以直接在命令行中启动和kill掉uwsgi服务,但为了更安全、方便的管理uwsgi服务,配置uwsgi到 systemd 服务中,同时实现开启自启的功能; 另,鉴于 supervisor 不支持 python3 ,没采用supervisor来管理uwsgi服务; 具体配置方法如下: step1. 创建配置文件 /etc/systemd/system/server_uwsgi. service step2. 填入以下内容 [Unit] Description=HTTP Interface Server After=syslog.target [Service] KillSignal=SIGQUIT ExecStart=/usr/bin/uwsgi --ini /path/uwsgi.ini Restart=always Type=notify NotifyAccess=all StandardError=syslog [Install] WantedBy=multi-user.target step3. 将该服务加入到systemd中 systemctl enable /etc/systemd/system/server_uwsgi.service

使用django自带后台管理系统,uwsgi启动css格式消失的问题

回眸只為那壹抹淺笑 提交于 2020-01-12 00:06:36
问题 :CSS加载的样式没有了, 原因 :使用了django自带的admin,在使用 python manage.py runserver启动 的时候,可以加载到admin的文件。 而在使用uwsgi启动的时候,一些网页需要的静态文件uwsgi没有找到,所以出现了比较丑陋的情况。 解决方法: 将admin的文件找出来放在static里面,通过uwsgi进行加载; step1: 先收集到all_static下,之后转移到static下; 在settings.py 里 添加 STATIC_ROOT=“all_static” STATIC_URL = '/static/' STATIC_ROOT = os . path . join ( BASE_DIR , 'all_static' ) ST . path . join ( BASE_DIR , 'static' ) ] MEDIA_ROOT = os . path . join ( BASE_DIR , 'static/media' ) 注意一定要是 STATIC_ROOT 不然收集不到 step2: 终端,在manage.py的同级下执行 python manage.py collectstatic 生成如下文件,admin文件是我们想要的。 step3: 将admin文件移动的static下;ps:这一步不是必要的
