Centos7 + Django + Nginx +Uwsgi

参考https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-uwsgi-and-nginx-on-centos-7

base_environment: CentOS7

1.安装uwsgi

yum install gcc python-devel  
pip install uwsgi

2.项目中写wsgi.py文件（放在manage.py同级目录下）

# coding: utf-8
import os

# We defer to a DJANGO_SETTINGS_MODULE already in the environment. This breaks
# if running multiple sites in the same mod_wsgi process. To fix this, use
# mod_wsgi daemon mode with each site in its own daemon process, or use
# os.environ["DJANGO_SETTINGS_MODULE"] = "forum.settings"
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "QCOMnewslettermanager.settings")

# This application object is used by any WSGI server configured to use this
# file. This includes Django's development server, if the WSGI_APPLICATION
# setting points here.
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

3.测试uwsgi是否安装成功

uwsgi --http :8200 --chdir /root/QCOM-newsletter-manager/QCOMnewslettermanager/ --wsgi-file wsgi.py

4.创建ini文件配置uwsgi

mkdir -p /etc/uwsgi/sites
mkdir /run/uwsgi
mkdir /var/log/uwsgi
cd /etc/uwsgi/sites
vim xx.ini

[uwsgi]

chdir = /var/project/QCOM-newsletter-manager/QCOMnewslettermanager/
module = wsgi:application

master = true
processes = 5

uid = nginx
socket = /run/uwsgi/QCOMnewslettermanager.sock
chown-socket = root:nginx
chmod-socket = 660
vacuum = true
daemonize = /var/log/uwsgi/newsletter.log
pidfile = /run/uwsgi/newsletter.pid

if error:

plugins = python 

5.创建uwsgi系统启动文件

vim /etc/systemd/system/uwsgi.service

[Unit]
Description=uWSGI Emperor service

[Service]
ExecStartPre=/usr/bin/bash -c 'mkdir -p /run/uwsgi; chown user:nginx /run/uwsgi
ExecStart=/usr/bin/uwsgi --emperor /etc/uwsgi/sites
Restart=always
KillSignal=SIGQUIT
Type=notify
NotifyAccess=all

[Install]
WantedBy=multi-user.target

6.安装nginx

yum install nginx

7.配置nginx

vim /etc/nginx/nginx.conf

server {  
    listen 80;  
    server_name 120.27.123.32;  
    location /static/ {  
        root /var/project/QCOM-newsletter-manager;  
    }  
    location / {  
        include uwsgi_params;  
        uwsgi_pass unix:/run/uwsgi/QCOMnewslettermanager.sock;  
    }  
}  

8.启动

sudo systemctl start nginx  
sudo systemctl start uwsgi（或者单独启动文件uwsgi --ini xx.ini）

9.QUESTION

• admin不加载css，js
  修改settings.py中static的ROOT路径，改为绝对路径后，python manage.py collectstatic
• 配置后无法提交图片
  修改用户组

chown -R nginx QCOM-newsletter-manager/
chgrp -R nginx QCOM-newsletter-manager/

• 报错：

uwsgi: option '--http' is ambiguous; possibilities: '--http-socket' '--https-socket-modifier2' '--https-socket-modifier1' '--https-socket' '--http-socket-modifier2' '--http-socket-modifier1' getopt_long() error

yum install uwsgi-plugin-python
plugins = python （加在ini配置文件中）
