sudo python3 makemigrations
sudo python3 migrate
sudo python3 collectstatic


Step 4: After installed the gunicorn needs to test that.

sudo gunicorn –bind btre.wsgi:application
Note: run it whether your code exists.
Step 5: Now create a gunicorn socket file.

sudo nano /etc/systemd/system/gunicorn.socket
[Copy and Paste the contents in socket file]
Description=gunicorn socket
Step 6: Create a service file.

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

[Copy andPaste the contents in service file]

Description=gunicorn daemon

WorkingDirectory=/home/(path of the code content directory)
ExecStart=/usr/local/bin/gunicorn(Path of the gunicorn) \
–access-logfile – \
–workers 3 \
–bind unix:/run/gunicorn.sock \

Step 7: Now enable the socket configuration.

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


Step 8: Check the status of the gunicorn.socket

sudo systemctl status gunicorn.socket

[Copy and Paste the content in file]

server {
listen 80;
server_name localhost;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /opt/workstation/code/btre_project;
}location / {
include proxy_params;
proxy_pass http://unix:/run/gunicorn.sock;

Step 3: Now create a soft link of the configure file.

sudo ln -s /etc/nginx/sites-available/file-name /etc/nginx/sites-enabled
Step 4: Test the nginx configuration if it is correct and restart nginx.

sudo nginx -t
sudo systemctl restart nginx
