uWSGI部署Django项目

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Django、Flask框架写的程序）通信的一种规范。

Windows环境安装uWSGI

 1、uWSGI包下载

直接在cmd中使用pip install uwsgi会报错，AttributeError: module 'os' has no attribute 'uname'

#离线下载uWSGI地址
https://pypi.org/project/uWSGI/#files

2、修改uwsgiconfig.py文件

#修改导入包
import platform
#将os.uname() 全部替换为platform.uname()

3、执行setup.py

#进入文件目录后再运行
python setup.py install

　　发现还是报错了，原因是没有C语言编译 Exception: you need a C compiler to build uWSGI 

4、下载安装MinGW

#参考安装MinGW
https://jingyan.baidu.com/article/0320e2c11564ca1b87507b8f.html

5、再次运行setup.py

      安装成功

　　

Centos7环境安装uWSGI

#安装python环境
yum install -y python3
#安装编译环境
yum install -y python3-devel gcc
#安装uWSGI
pip3 install uWSGI

uWSGI启动Django

1、创建django项目

django-admin startproject testproject

  

2、启动django 的配置

在与settings.py 同级目录下新建wsgi.py

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "projectName.settings")

application = get_wsgi_application() 

　　

在与manager.py同级目录下创建uwsgiConfig/uwsgiConfig.ini

[uwsgi]
#项目目录
chdir = /usr/local/src/sykj-portal/sykj_website
# 虚拟环境
home=/usr/local/src/pyENV/sykj_website_ENV/
PYTHONHOME=/usr/local/src/pyENV/sykj_website_ENV//bin/
#启动uwsgi的用户名和用户组
uid = root
gid = root
#指定项目的application
module = sykj_website.wsgi:application
#启用主进程
master = True
#进程个数
processes = 2
# 使用进程数  threads = 2 使用的线程数
harakiri = 60
# 最大超时时间
max-requests = 5000
# 最大请求数，到了后就会自动重启
#指定socket
#socket = 127.0.0.1:3000  
#指定http
http = 0.0.0.0:3000
socket = /usr/local/src/sykj-portal/sykj_website/uwsgi/sock/supercrm.sock
#配置pid文件位置
pidfile = /usr/local/src/sykj-portal/sykj_website/uwsgi/master.pid
# 配置日志文件位置
daemonize = /usr/local/src/sykj-portal/sykj_website/uwsgi/log/uwsgi.log
# 服务退出或重启，自动删除pid和socket文件
vacuum = True
#序列化接受的内容，如果可能的话
thunder-lock = True
#启用线程
enable-threads = True
#设置自动中断时间
harakiri = 30
#设置缓冲
post-buffering = 4096
#项目中静态文件static的路径
static-map = /static=/usr/local/src/sykj-portal/sykj_website/sykj-static

设置项目自动启动

#赋予rc.local可执行权限
chmod +x /etc/rc.d/rc.local

#在rc.local添加启动脚本路径
/usr/local/src/.../start_project.sh

#使rc.local文件生效
source /etc/rc.d/rc.local
