Flask Flask on Apache with mod_wsgi Apache sites-enabled configuration for WSGI
Example
The advantage of using Apache over the builtin werkzeug server is that Apache is multi-threaded, meaning that multiple connections to the application can be made simultaneously. This is especially useful in applications that make use of XmlHttpRequest (AJAX) on the front-end.
/etc/apache2/sites-available/050-my-application.conf (or default apache configuration if not hosted on a shared webserver)
<VirtualHost *:80>
ServerName my-application.org
ServerAdmin [email protected]
# Must be set, but can be anything unless you want to serve static files
DocumentRoot /var/www/html
# Logs for your application will go to the directory as specified:
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# WSGI applications run as a daemon process, and need a specified user, group
# and an allocated number of thread workers. This will determine the number
# of simultaneous connections available.
WSGIDaemonProcess my-application user=username group=username threads=12
# The WSGIScriptAlias should redirect / to your application wrapper:
WSGIScriptAlias / /path/to/my-application/my-application.wsgi
# and set up Directory access permissions for the application:
<Directory /path/to/my-application>
WSGIProcessGroup my-application
WSGIApplicationGroup %{GLOBAL}
AllowOverride none
Require all granted
</Directory>
</VirtualHost>
