Instalación rápida de Gunicorn utilizando Systemd

Introducción

Creamos un servicio, en este caso se llamara como mi blog.

    [alberto@barrahome barrahome-flask]$ sudo nano /etc/systemd/system/barrahome.service

Agregamos el siguiente contenido:

    [Unit]
    Description=Barrahome web application
    After=network.target

    [Service]
    User=alberto
    Group=alberto
    WorkingDirectory=/home/alberto/barrahome-flask
    ExecStart=/usr/bin/python3 /usr/bin/gunicorn --bind 0.0.0.0:8000 boot:app

    [Install]
    WantedBy=multi-user.target

Habilitamos el servicio y luego recargamos systemd y sus servicios:

    [alberto@barrahome barrahome-flask]$ sudo systemctl daemon-reload
    [alberto@barrahome barrahome-flask]$ sudo systemctl start barrahome
    [alberto@barrahome barrahome-flask]$ sudo systemctl status barrahome
