This is a story all about how, my life got twist turned upside down – by PHP5-CGI on Debian Lenny.
The documentation on this isn’t the best, so here’s how I was able to get PHP5 running.
All commands are assumed to be run as root.
apt-get install php5-cgi
Installs PHP5-CGI, obviously.
Add in the following 3 lines, save and quit
ScriptAlias /php5-cgi /usr/lib/cgi-bin/php5 Action php5-cgi /php5-cgi AddHandler php5-cgi .php
Enables Actions, above
Reloads the apache configurations, and you should be good to go!
