问题 What are the benefits of running uWSGI in master mode if I'm only running a single app? Does master mode offer process management benefits that make it more reliable than, say, running via Upstart? 回答1: upstart is only a process manager, the uWSGI master has access to lot of memory areas of workers (well it is the opposite indeed) so it can make truly monitoring of the behaviour of workers, in addition to this it allows graceful reloading, exports statistics and dozens of other things.

Flask容器化部署原理与实现

本文将介绍Flask的部署方案:Flask + Nginx + uWSGI,并使用docker进行容器化部署,部署的实例来源 Flask开发初探 ,操作系统为ubuntu。 Flask系列文章 : Flask开发初探 WSGI到底是什么 Flask源码分析一:服务启动 Flask路由内部实现原理 部署方案 在开发时,我们使用flask run命令启动的开发服务器是werkzeug提供的,但是这种方式目的是为了开发,不能很好的扩展,不适合生产部署。生产部署,我们需要一个更强健,性能更高的WSGI服务器(关于WSGI,可参考 WSGI到底是什么 ,常用的服务器有:uWSGI、Gunicorn等,本文以uWSGI举例。 像uWSGI这类WSGI服务器内置了Web服务器,所以我们不需要web服务器也可以与客户端交换数据,处理请求和响应,但是内置的web服务器不够强健,一般情况下都会使用一个常规的web服务器运行在前端,为WSGI服务器提供反向代理,web服务器选择Nginx,Nginx会把外部的请求转发给uWSGI处理,接收到响应后再返回给客户端,这样做的好处有: 提高静态文件的效率,因为Nginx处理静态文件的速度非常快 提升系统安全性,避免直接暴露WSGI服务器 提升程序处理能力,通过设置反向代理,配置负载均衡可以实现。 uWSGI配置 在使用uwsgi部署flask应用时

1,申请域名证书成功后,下载压缩包,一定要选择Nginx的证书类型,解压后得到一个key文件一个pem文件,将这两个文件上传到服务器的root目录 2,打开nginx配置文件 vim /etc/nginx/conf.d/default.conf 同时添加http和https的协议配置,需要注意的是,http需要阿里云安全协议暴露80端口,https需要阿里云安全协议暴露443端口 server { listen 80; server_name vip.queyou688.com; rewrite ^(.*)$ https://${server_name}$1 permanent; access_log /root/myweb_access.log; error_log /root/myweb_error.log; client_max_body_size 75M; location / { include uwsgi_params; uwsgi_pass 127.0.0.1:8001; uwsgi_param UWSGI_SCRIPT dms.wsgi; uwsgi_param UWSGI_CHDIR /root/dms; } location /static { alias /root/dms/static; } } server { listen 443 ssl;

Django 是一个用 Python 实现的 web 框架, 使用django 部署 web 项目可以说是迅速方便, django 的许多特性都让我爱不释手, 如默认的 sqllite 数据库, 强大后台管理, 自带的 XXS 的表单验证, 基于 MVC 的设计, 写不到两百行代码就可以搭建一个网站. 这里我使用的是阿里云的 centos7 + nginx 为例, 部署第一个 django 项目. 服务器: 阿里云 centos 7.4 数据库: MariaDB 5.5.56 http代理: Nginx django: 1.11.7 先在阿里云控制台 -> 安全组 -> 配置规则 -> 添加安全组规则 端口范围: 80/80 授权对象: 0.0.0.0/0 其余默认 安装 MariaDB 5.5.56 MariaDB 是 centos 中 MySQL 的替代品, 使用与 MySQL 一致 yum install -y mariadb mariadb-server yum install -y mysql-devel python-devel python-setuptools pip install mysql-python 启动 Mariadb 服务 systemctl start mariadb 登入, 修改密码, 创建数据库, 作为 django 项目的默认数据库 #

How to create one uwsgi log file per day?

吃可爱长大的小学妹 提交于 2019-12-09 15:42:04
问题 I use uwsgi with the parameter --daemonize /logs/uwsgi.log This file is however becoming large and I would like to split it into smaller pieces. One per day would be preferable. I have done that for nginx where it was easy to specify the log file name using date variables. Is it possible to do the same for uwsgi? Something like: [uwsgi] daemonize=/logs/uwsgi-$year-$month-$day.log Or is there another way to get the same result, without too much involvement of other processes? 回答1: uWSGI by
