...
STATIC_ROOT = os.path.join(BASE_DIR, ‘static’)

• Kumpulkan semua konten static ke direktori yg telah ditentukan.

$ python3 manage.py collecstatic

• Allow firewall.

$ sudo ufw allow 8000

• Coba jalankan server.

$ python3 manage.py runserver 0.0.0.0:8000

• Coba jalankan server menggunakan gunicorn.

$ gunicorn --bind 0.0.0.0:8000 perpus.wsgi

• Keluar dari virtual environment.

$ deactivate

• Buat service unicorn

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

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=zulx
Group=www-data
WorkingDirectory=/home/zulx/perpus
ExecStart=/home/zulx/perpus/.env/bin/gunicorn --access-logfile - --workers 3 --bind unix:/home/zulx/perpus/perpus.sock perpus.wsgi:application

$ sudo systemctl start gunicorn
$ sudo systemctl enable gunicorn
$ sudo systemctl status gunicorn

• Jika ada perubahan pada file gunicorn.service..

$ sudo systemctl daemon-reload
$ sudo systemctl restart-gunicorn

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/zulx/perpus;

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/zulx/perpus/perpus.sock;
    }
}

• Enable Nginx

$ ln -s /etc/nginx/sites-available/perpus /etc/nginx/sites-enabled/
$ nginx -t
$ sudo systemctl restart nginx

• Buat firewall

$ sudo ufw delete allow 8000
$ sudo ufw allow ‘Nginx Full’
