Deploying Django using Ngnix and Gunicorn on Ubuntu

First of all,  I am going to install MySQL database because we are using it in our project

Installing MySQL 

Update 

sudo apt update

Then install the mysql-server package:

sudo apt install mysql-server

Ensure that the server is running using the systemctl start command:

sudo systemctl start mysql.service

Configure Mysql

mysql_secure_installation

We are  not going to use root user , so we will create new user 

Creating New MySQL User

mysql -u root -p

CREATE USER 'username'@'host' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO ‘user’@'host’;

FLUSH PRIVILEGES;

exit

Now you can login with your username and password using command:

mysql -u username -p 

 

Deploying Django with Nginx and Guicorn

Install python, pip and Ngnix 

sudo apt install python3-pip python3-dev nginx

Creating a python virtual environment 

sudo apt install virtualenv

Create project folder 

cd /
mkdir projects
cd projects

I have created projects folder at root.

Create and activate the virtual env

virtual env 
source env/bin/activate

Upload the django project  

I am going to clone the project from github as i have project on github.

git clone https://github.com/DurgeshCoder/lcwd-back.git

cd lcwd-back

pip3 install -r requirements.txt

 

If you have any migrations then migrate and also put the correct database details in settings.py file

python3 manage.py migrate

Now test application is running on development server or not

python3 manage.py runserver 0.0.0.0:8000

Check using IP and Port 8000.

Now use Gunicorn 

Let's create a system socket file for gunicorn now:

sudo vim /etc/systemd/system/gunicorn.socket

Paste the contents below and save the file

Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock

[Install]
WantedBy=sockets.target```

Next, we will create a service file for gunicorn

sudo vim /etc/systemd/system/gunicorn.service 

Paste the contents below inside this file:

Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

[Service]
User=ubuntu
Group=www-data
WorkingDirectory=/projects/lcwd-back
ExecStart=/projecgs/env/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/gunicorn.sock \
          textutils.wsgi:application

[Install]
WantedBy=multi-user.target```

Lets now start and enable the gunicorn socket

sudo systemctl start gunicorn.socket
sudo systemctl enable gunicorn.socket

Configurations of Ngnix

sudo vim /etc/nginx/sites-available/lcwd

Paste the below contents inside the file created

listen 80;
server_name www.learncodewithdurgesh.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /projects/lcwd-back;
    }

    location /media/ {
        root /projects/lcwd-back;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }

}

Activate the configuration using the following command:

sudo ln -s /etc/nginx/sites-available/lcwd /etc/nginx/sites-enabled/ 

Restart nginx and allow the changes to take place.

sudo systemctl restart nginx

Now check on port 80 your site will run.
