To Host App

git clone https://github.com/RiajulKashem/shop_men.git


mkvirtualenv config
pip install -r requirements.txt
python3 manage.py makemigrations && python3 manage.py migrate
echo "from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'riajulkashem@gmail.com', 'admin')" | python manage.py shel

python3 manage.py collectstatic

sudo ufw allow 8080
python3 manage.py runserver 0.0.0.0:8080
deactivate

Install uWsgi

sudo apt-get install python3-dev
sudo -H pip3 install uwsgi

Test uWsgi

uwsgi --http :8080 --home /home/user/Env/config --chdir /home/user/config -w config.wsgi

uwsgi --http :8080 --home /root/Env/config --chdir /opt/config -w config.wsgi

Creating Configuration Files

sudo mkdir -p /etc/uwsgi/sites
sudo nano /etc/uwsgi/sites/config.ini

in configuration file write

[uwsgi]
project = config
uid = riajul
base = /home/%(uid)

chdir = %(base)/%(project)
home = %(base)/Env/%(project)
module = %(project).wsgi:application

master = true
processes = 5

socket = /run/uwsgi/%(project).sock
chown-socket = %(uid):www-data
chmod-socket = 660
vacuum = true

Create a systemd Unit File for uWSGI

sudo nano /etc/systemd/system/uwsgi.service

Start with the [Unit] section, which is used to specify metadata and ordering information. We’ll simply put a description of our service here:

[Unit]
Description=uWSGI Emperor service

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

[Install]
WantedBy=multi-user.target

Install and Configure Nginx as a Reverse Proxy

sudo apt-get install nginx
sudo nano /etc/nginx/sites-available/config

in project(config in sites-available) write

server {
    listen 80;
    server_name 159.65.137.34;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        alias /home/riajul/config/static/;
    }

    location / {
        include         uwsgi_params;
        uwsgi_pass      unix:/run/uwsgi/config.sock;
    }
}

Next, link both of your new configuration files to Nginx’s sites-enabled directory to enable them

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

Check the configuration syntax by typing: sudo nginx -t If no syntax errors are detected, you can restart your Nginx service to load the new configuration

sudo systemctl restart nginx
sudo systemctl start uwsgi
sudo ufw delete allow 8080
sudo ufw allow 'Nginx Full'
sudo systemctl enable nginx
sudo systemctl enable uwsgi

Restart Server

sudo systemctl daemon-reload
sudo systemctl restart uwsgi
sudo nginx -t && sudo systemctl restart nginx
