Many ikiwiki examples name the [[cgi]] "ikiwiki.cgi", and put it somewhere like `~/public_html/ikiwiki.cgi`, or `/var/www/wiki/ikiwiki.cgi`. If you follow those examples, you may find that when trying to edit a page in your wiki, you see the raw contents of the ikiwiki.cgi program. Or get a permission denied problem. This is because apache is generally not configured to run cgi scripts unless they're in `/usr/lib/cgi-bin/`. While you can put ikiwiki.cgi in there if you like, here's how to configure apache (version 2) to run `.cgi` programs from anywhere. These instructions are for Debian systems, but the basic apache configuration should work anywhere. * Edit /etc/apache2/apache2.conf and add a line like this: AddHandler cgi-script .cgi * Find the "Options" line for the directory where you've put the ikiwiki.cgi, and add "ExecCGI" to the list of options. For example, if ikiwiki.cgi is in /var/www/, edit `/etc/apache2/sites-enabled/000-default` and add it to the "Options" line in the "Directory /var/www/" stanza. Or, if you've put it in a `~/public_html`, edit `/etc/apache2/mods-available/userdir.conf`.
