Tutorial on how to deploy a Django application on Linux VPS with Apache, NGINX and uWSGI

Preparing the environmnet

sudo apt-get install python3-venv

• Create virtual env

python3 -m venv venv

• Clone repository

git clone your-url.git

• Install requirementst pip install -r requirements.txt

• Run the collectstatic command python manage.py collectstatic

• Create the database python manage.py migrate

• Create a superuser python manage.py createsuperuser

Setup static and media files

• Make sure your settings.py has the following configurations:

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, "static")

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

• Run Django collectstatic python manage.py collectstatic

Install and setup

• Install uwsgi on your virtual environment

sudo apt-get install python3.6-dev
sudo apt-get install build-essential libssl-dev libffi-dev python-dev
pip install wheel
pip install uwsgi

• Install and start Nginx

sudo apt-get install nginx
sudo /etc/init.d/nginx start

Configure Nginx

• Create the file uwsgi_params on your project path

vim uwsgi_params

---- file content -----

uwsgi_param  QUERY_STRING       $query_string;
uwsgi_param  REQUEST_METHOD     $request_method;
uwsgi_param  CONTENT_TYPE       $content_type;
uwsgi_param  CONTENT_LENGTH     $content_length;

uwsgi_param  REQUEST_URI        $request_uri;
uwsgi_param  PATH_INFO          $document_uri;
uwsgi_param  DOCUMENT_ROOT      $document_root;
uwsgi_param  SERVER_PROTOCOL    $server_protocol;
uwsgi_param  REQUEST_SCHEME     $scheme;
uwsgi_param  HTTPS              $https if_not_empty;

uwsgi_param  REMOTE_ADDR        $remote_addr;
uwsgi_param  REMOTE_PORT        $remote_port;
uwsgi_param  SERVER_PORT        $server_port;
uwsgi_param  SERVER_NAME        $server_name;

• Create NGINX config file at /etc/nginx/sites/available

upstream django {
    server unix:///home/ubuntu/django-apache-nginx-uwsgi-vps-ubuntu/mysite.sock; 
}

server {
    listen      8000;
    server_name example.com;
    charset     utf-8;

    client_max_body_size 75M; 

    location /media  {
        alias /home/ubuntu/django-apache-nginx-uwsgi-vps-ubuntu/media; 
    }

    location /static {
        alias /home/ubuntu/django-apache-nginx-uwsgi-vps-ubuntu/static;
    }

    location / {
        uwsgi_pass  django;
        include     /home/ubuntu/django-apache-nginx-uwsgi-vps-ubuntu/uwsgi_params; 
    }
}

• Create a symlink on sites-enabled sudo ln -s ~/path/to/your/mysite/mysite_nginx.conf /etc/nginx/sites-enabled/

• Restart Nginx sudo /etc/init.d/nginx restart

• Download an image to media folder and test

• Run and test using Unix sockets uwsgi --socket mysite.sock --module mysite.wsgi --chmod-socket=666

• Create the ini file

[uwsgi]
chdir           = /home/ubuntu/django-apache-nginx-uwsgi-vps-ubuntu
module          = django_vps.wsgi
home            = /home/ubuntu/venv
master          = true
processes       = 10
socket          = /home/ubuntu/django-apache-nginx-uwsgi-vps-ubuntu/mysite.sock
vacuum          = true
chmod-socket    = 666

• Testing with .ini file uwsgi --ini mysite_uwsgi.ini

Configuring the uWSGI as Emperor mode

sudo mkdir /etc/uwsgi
sudo mkdir /etc/uwsgi/vassals
sudo ln -s /home/ubuntu/django-apache-nginx-uwsgi-vps-ubuntu/mysite_uwsgi.ini /etc/uwsgi/vassals/
uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data

Setup systemctl to start on boot

https://uwsgi-docs.readthedocs.io/en/latest/Systemd.html

cd /etc/systemd/system/

sudo vim djangovps.service


======
[Unit]
Description=Django VPS uWSGI Emperor
After=syslog.target

[Service]
ExecStart=/home/ubuntu/venv/bin/uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data
RuntimeDirectory=uwsgi

======

sudo chmod 664 /etc/systemd/system/djangovps.service

sudo systemctl daemon-reload

sudo systemctl enable djangovps.service

 sudo systemctl start djangovps.service

 sudo systemctl status djangovps.service

journalctl -u djangovps.service

Setup Apache2 with Nginx as a reverse Proxy

• disable nginx default symlink to open port 80

 cd /etc/nginx/sites-enabled/
 sudo rm -rf default
 sudo /etc/init.d/nginx restart

sudo apt-get install apache2
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod proxy_balancer
sudo a2enmod lbmethod_byrequests

sudo systemctl restart apache2

• Creating the Vhost

cd /etc/apache2/sites-available
sudo vim django_vps.conf

<VirtualHost *:80>
    ServerName 52.16.70.162
    ProxyPass / http://127.0.0.1:8000/
    ProxyPassReverse / http://127.0.0.1:8000/
</VirtualHost>

• Enable symlink on site-enable

sudo ln -s /etc/apache2/sites-available/django_vps.conf /etc/apach
e2/sites-enabled/

• Edit default vhost to your extra website

Setup Django to user Postgres DB

sudo apt-get install python-pip python-dev libpq-dev postgresql postgresql-contrib
adduser <username>
sudo su - postgres
psql
\password
\q
createuser --interactive
createdb <database name>
psql
ALTER DATABASE <database name> OWNER TO <role name>;
ALTER USER <username> WITH PASSWORD '<new password>';
add psycopg2 on requirements.txt
push + pull
install requirements.txt

Consultando o banco de dados

sudo su
su postgres
psql
\list
\c djangodb
\dt ( show tables )
select * from auth_user;
\q
exit
