Hi I am trying to deploy my Django Project to Production for the first time using Nginx and gunicorn on linode.
Currently I did not set a venv file I just downloaded all the requirements in the system as a whole. I am using Linode Server and selected Django from the market place and the set system is Debian. The project was working perfectly well with portal 8000 but now I am trying to take it to development.
I have made the following steps: sudo nano /etc/systemd/system/gunicorn.service
[Unit]
Description=Gunicorn service for project
After=network.target
[Service]
User=www-data
Group=www-data
WorkingDirectory=/var/www/DjangoApp/
ExecStart=/usr/local/bin/gunicorn --workers 3 --bind unix:/var/www/DjangoApp/project.sock project.wsgi:application
[Install]
WantedBy=multi-user.target
I can't find the sock file in the project but this is the tree of the project if it helps cd /var/www/DjangoApp:
api db.sqlite3 project manage.py media README.md requirements.txt static tac users
in the /var/www/DjangoApp/project
asgi.py __init__.py __pycache__ settings.py urls.py wsgi.py
in my sudo nano /etc/nginx/sites-available/project
server {
listen 80;
server_name 111.111.111.11;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /var/www/DjangoApp/;
}
location / {
include proxy_params;
proxy_pass http://unix:/var/www/DjangoApp/project.sock;
}
}
here is the log error

My question: Where can I find the .sock file to connect to it to fix this error. Any suggestions would be appreciated to find solution to fix 502 Bad Gateway
Before creating the service file you need to create systemd Socket that in turn create the sock file, to do that you need to create a file under /etc/systemd/system/<file name you want> like the following.
sudo nano /etc/systemd/system/gunicorn_django_app.socket
in that file you need to provide the following details
[Unit]
Description=Gunicorn service for project
[Socket]
ListenStream=/run/gunicorn_django_app.sock
[Install]
WantedBy=sockets.target
This will create a sock file under /run/gunicorn_django_app.sock
Then you need to create a systemd service file in the path /etc/systemd/system/<file name you like>
like the following
sudo nano /etc/systemd/system/gunicorn_django_app.service
In the file you need to provide service related details
[Unit]
Description=gunicorn daemon
Requires=gunicorn_django_app.socket
After=network.target
[Service]
User=username # user that can access those files
Group=www-data # group that can access those files
WorkingDirectory=<projectpath>
ExecStart=/<guincorn path>\
--access-logfile - \
--workers 3 \
--bind unix:/run/gunicorn_django_app \
DjangoApp.wsgi:application
then you have to start the services
sudo systemctl start gunicorn_django_app.socket
sudo systemctl enable gunicorn_django_app.socket
to know more use the below link this will help you to understand more on this concepts. it's in ubuntu linux but debain based linux (it will work on Linode too) digitalocean
