Instalar mod-wsgi
$ sudo apt-get update $ sudo apt-get install libapache2-mod-wsgi
Configurar usuario
$ useradd -M flask $ usermod -s /bin/false flask $ usermod -L flask $ adduser flask www-data
lanzador.wsgi
#!/usr/bin/env python # -*- coding: utf-8 -*- # Si usamos virtualenv activate_this = '/ruta/al/env/bin/activate_this.py' execfile(activate_this, dict(__file__=activate_this)) # Si no está instalada la app: para poder importar import sys sys.path.insert(0, '/ruta/a/la/aplicacion') from <miaplicacion> import app as application
- Tiene que tener permisos de ejecución
$ chmod +x lanzador.wsgi
virtual host en apache
<VirtualHost *:80> ServerName example.com WSGIDaemonProcess yourapplication user=user1 group=group1 threads=5 home=/var/wwww/home ... WSGIScriptAlias / /var/www/yourapplication/lanzador.wsgi <Directory /var/www/yourapplication> WSGIProcessGroup yourapplication WSGIApplicationGroup %{GLOBAL} WSGIScriptReloading On Order deny,allow Allow from all </Directory> </VirtualHost>
$ sudo a2ensite nuevo_sitio $ sudo service apache2 restart | reload
Si hay errores ...
$ tail -f /var/log/apache/error.log
con userdir
<Directory /home/*/public_html> Options Indexes FollowSymLinks MultiViews ExecCGI AddHandler wsgi-script .wsgi Order allow,deny Allow from all </Directory>

- Si usamos sqlite el archivo tiene que tener permisos de escritura para apache!!! (Y el directorio si apache tiene que crear un archivo)

login por https
Del ejemplo de flaskr. Uso de url_for:
url_for('<destino>', _external=True, _scheme='http|https'))
@app.route('/login', methods=['GET', 'POST']) def login(): if not request.is_secure: return redirect(url_for('login', _external=True, _scheme='https')) error = None if request.method == 'POST': if request.form['username'] != app.config['USERNAME']: error = 'Invalid username' elif request.form['password'] != app.config['PASSWORD']: error = 'Invalid password' else: session['logged_in'] = True flash('You were logged in') return redirect(url_for('show_entries', _external=True, _scheme='http')) return render_template('login.html', error=error)
