Django+uWSGI+nginx 水深无声 2022-02-18 09:41 216阅读 0赞 Django是一个开源的Web应用框架，由Python写成，基于MTV的框架模式。 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。 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，可用于uWSGI和Django进行交互。 uwsgi是一种线路协议，用于uWSGI与其它网络服务器（比如nginx）之间进行交互。 ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjU5NTAxMg_size_16_color_FFFFFF_t_70][] -------------------- **1.安装uWSGI** [root@syztoo syztoo]# pip3 install uwsgi -------------------- **2.使用uWSGI启动项目** [root@syztoo syztoo]# uwsgi --http :8000 --module syztoo.wsgi *** Starting uWSGI 2.0.18 (64bit) on [Wed Apr 17 11:06:55 2019] *** compiled with version: 4.8.5 20150623 (Red Hat 4.8.5-36) on 11 April 2019 11:41:12 os: Linux-3.10.0-957.5.1.el7.x86_64 #1 SMP Fri Feb 1 14:54:57 UTC 2019 nodename: syztoo machine: x86_64 clock source: unix pcre jit disabled detected number of CPU cores: 1 current working directory: /home/syztoo detected binary path: /usr/local/python3/bin/uwsgi uWSGI running as root, you can use --uid/--gid/--chroot options *** WARNING: you are running uWSGI as root !!!
