Ejercicio 1: Desplegando aplicaciones flask con Apache + mod_wsgi

En esta tarea se usa la aplicación Guestbook.

Crear venv

mkdir venv
cd venv
sudo apt update
sudo apt install python3-venv
python3 -m venv .
source bin/activate

Descargar Guestbook

sudo apt install git
git clone https://github.com/josedom24/guestbook.git
pip install -r requirements.txt
sudo apt install redis

Probar funcionamiento

Por ahora, usando el servidor de desarrollo:

python3 app.py

Fichero wsgi

/home/vagrant/guestbook/app/wsgi.py

from app import prog as application

Hacer que Apache sirva Guestbook

sudo apt install apache2
sudo apt install libapache2-mod-wsgi-py3

Creo /etc/apache2/sites-available/guestbook.conf:

<VirtualHost *:80>

        ServerName www.guestbook.com
        DocumentRoot /home/vagrant/guestbook/app

        <Directory /home/vagrant/guestbook/app>
            Require all granted
        </Directory>

        WSGIDaemonProcess guestbook python-path=/home/vagrant/guestbook/app:/home/vagrant/venv/lib/python3.9/site-packages
        WSGIProcessGroup guestbook
        WSGIScriptAlias / /home/vagrant/guestbook/app/wsgi.py process-group=guestbook

</VirtualHost>

Lo habilito:

sudo a2ensite guestbook.conf

Reinicio Apache:

sudo systemctl restart apache2

Modifico mi /etc/hosts:

# ej1-apps-flask-apache2-mod_wsgi resolutions
