Django application deployment with nginx and uwsgi (Ubuntu)

Deploy for Flask application follow here

Prequisite

• Django
• uwsgi
• nginx

Setup your django project

https://docs.djangoproject.com/en/2.2/intro/tutorial01

Install uwsgi

pip3 install uwsgi

Install Nginx (Web Server)

sudo apt get install nginx

# check nginx is running or not
sudo systemctl status nginx.service

# output should be
● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)

Configure uWSGI

Check your project working fine with uwsgi.

uwsgi --http :8000 --module mysite.wsgi

Create .ini configuration file

In the same project root directory, create a .ini file for uwsgi configuration. For example myproject.ini

# mysite_uwsgi.ini file
[uwsgi]

project_dir = %d

# Django-related settings
# the base directory (full path)
chdir           = %(project_dir)
# Django's wsgi file
module          = mysite.wsgi

# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 1
# the socket (use the full path to be safe
socket          = 127.0.0.1:1200
# ... with appropriate permissions - may be needed
# chmod-socket    = 664
# clear environment on exit
vacuum          = true

die-on-term = true

Save file and test ini file, run command in terminal.

uwsgi --ini mysite.ini

Create a uWSGI startup file

So that we can start/stop django application service, as we do for other system services.

create a systemctl startup file at location /etc/systemd/system. For example /etc/systemd/system/mysite.service

[Unit]

Description="uWsgi server instance for mysite"
After=network.target

[Service]
User={you-user}
Group=www-data
WorkingDirectory=/home/{you-user}/path/myproject/
Environment="PATH=/home/{you-user}/virtualenvs/mysite/bin"
ExecStart=/home/{you-user}/virtualenvs/myproject/bin/uwsgi --ini /home/{you-user}/path/myproject/mysite.ini

[Install]
WantedBy=multi-user.target

Start myproject service and check status

sudo systemctl start mysite.service

# Check the status
sudo systemctl status mysite.service

Configure Nginx

server {
    listen 80;
    server_name 127.0.0.1 localhost;

    location @application {
        include uwsgi_params;
        uwsgi_pass 127.0.0.1:1200;
    }
}

Test your Nginx configuration and restart Nginx.

nginx -t -c /etc/nginx/nginx.conf
# output should be
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

/etc/init.d/nginx restart

hat’s it. Open your localhost in browser and you will see application running with nginx and uwsgi.
