Synnefo v0.14.8 release introduced support for Debian Wheezy (and Django 1.4). To upgrade from Squeeze to Wheezy you should make sure to change the 'ENGINE' option in /etc/synnefo/10-snf-webproject-databases.conf to 'django.db.backends.postgresql_psycopg2. Replace postgresql_psycopg2 with the DB engine you are using.
If you’re upgrading to Synnefo v0.14.8 on Squeeze, you should also make sure to have the Squezee backports repository installed, since snf-webproject depends on >=python-django-south-0.7.3, which on Squeeze is only available from the backports repository.
Since v0.14.8, Synnefo also ships an example Gunicorn configuration file, that gets installed automatically at /etc/gunicorn.d/synnefo.example. To use it you need to do two things:
# mv /etc/gunicorn.d/synnefo.example /etc/gunicorn.d/synnefo
Finally, add any other special configuration option needed by your deployment in this file.
Warning
The logging location for the Synnefo gunicorn project has changed in /etc/gunicorn.d/synnefo.example: The default configuration no longer stores logs under /var/log/gunicorn/synnefo.log, but under /var/log/synnefo/gunicorn.log instead, for two reasons: a) uniformity with the rest of Synnefo, b) the version of gunicorn included in Wheezy now drops privileges to www-data:www-data properly, so it can no longer log under /var/log/gunicorn, which is owned by root.
