Installation on Apache with WSGI

This is what is used to host the Demo site & Trac (sharing just 128Mb RAM!)

• mod_rewrite: ​http://web2py.com/AlterEgo/default/show/144

If running on a UNIX variant (as would be recommended) then suggest using the ​Native Cron

vim /etc/crontab
0-59/1 * * * * www-data cd /var/www/web2py/ && python web2py.py -C -D 1 >> /tmp/cron.output 2>&1

cp /var/www/web2py/options_std.py /var/www/web2py/options.py
vim /var/www/web2py/options.py
extcron = True

Ubuntu

apt-get install libapache2-mod-wsgi
a2enmod rewrite
a2enmod deflate
a2enmod headers
a2enmod expires
vim /etc/apache2/sites-available/eden
