Detailed steps to start the Django project with nginx+uwsgi

nginx+uwsgi+django is our commonly used Django deployment method. As the front-end server, nginx is responsible for receiving all client requests. The requested static files are processed by the nginx server itself because it has a good ability to handle static files, has optimized performance, and supports high concurrency. The uWSGI server is a support server that is used to serve nginx. nginx hands the requested dynamic files to uWSGI for processing. uWSGI implements the uwsgi, wsgi and http protocols. The uwsgi protocol is a custom protocol of uWSGI, which defines the interface between the framework (django) and the server.

1. Install the project environment

System environment: Ubuntu 16.04

Python environment: python3.5.2

Django version: django1.11.7

Nginx environment: nginx_1.10.3

Virtual environment: virtualenv15.1.0

uwsgi version: uwsgi2.0.17.1

Install and enter the project virtual environment:

sudo apt-get install virtualenv
virtualenv -p python3 env_my_project 
source env_my_project/bin/activate
pip install -r requirements.txt

2. Project configuration and operation test

Modify the project configuration file:

cp my_project/settings_local.py.example my_project/settings_local.py

Modify the es configuration file:

cp rs_es/es_settings.py.example rs_es/es_settings.py

wsgi.py:

import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "my_project.settings_local")
application = get_wsgi_application()

Project running test:

python manage.py collectstatic # Collect static files python manage.py makemigrations
python manage.py migrate
python manage.py runserver 0.0.0.0:8001

3. NGINX and UWSGI related configuration

sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/my_project
sudo ln -s /etc/nginx/sites-available/my_project /etc/nginx/sites-enabled/
sudo vim /etc/nginx/sites-enabled/my_project

nginx configuration:

upstream my_project{
 server unix:///var/run/my_project.sock;
}

server {
 listen 8001; //The service port number service is started through nginx and uwsgi communication server_name 192.168.xx.xx; //The ip of nginx proxy 
 charset utf-8;

 # max upload size
 client_max_body_size 10M;

 # send all non-media requests to the Django server.
 location / {
  uwsgi_pass my_project;
  include /etc/nginx/uwsgi_params;
 }

 location /static/ {
  root /home/ubuntu/my_project;
 }
}

Uwsgi configuration:

sudo mkdir /var/log/uwsgi
sudo chmod -R 777 /var/log/uwsgi

uwsgi.ini:
[uwsgi]
chdir=/home/ubuntu/my_project
home=/home/ubuntu/my_project/env_my_project
module=my_project.wsgi:application

socket=/var/run/my_project.sock
chmod-socket = 666

master=True
processes = 5
max-requests=5000

# clear environment on exit
vacuum=True

pidfile=/var/run/my_project.pid
daemonize=/var/log/uwsgi/my_project.log

# git pull automatically restarts the service touch-reload=.git/index

4. Configure Emperor mode monitoring and system automatic startup of uwsgi

Configure Emperor mode listening

sudo mkdir /etc/uwsgi
sudo mkdir /etc/uwsgi/vassals
sudo ln -s /home/ubuntu/my_project/uwsgi.ini /etc/uwsgi/vassals/

The system automatically starts uwsgi

sudo vim /etc/rc.local
/usr/local/bin/uwsgi --emperor /etc/uwsgi/vassals

5. Start Django service through uwsgi

Start uwsgi

uwsgi --ini uwsgi.ini

Restart nginx

sudo service nginx restart

Start the Django service

sudo uwsgi --reload /var/run/my_project.pid

At this point, you can access the service through the ip and port proxy from ngnix in the browser
