+To run CGI under nginx, just use a FastCGI wrapper like [this one](http://technotes.1000lines.net/?p=23). The wrapper must be started somehow just like any other FastCGI program. I use launchd on OSX.
+
+In Linux, you will need the spawn-fcgi and fcgiwrap packages and start
+them with:
+
+ spawn-fcgi -s /tmp/fcgi.socket -n -- /usr/sbin/fcgiwrap
+
+This needs to be ran as your user. It can be added to `inittab` or
+made into a startup script in `init.d`.
+
+Then you need an nginx config plugged in that wrapper. Here's an
+example virtual host configuration:
+
+ server {
+ #listen 80; ## listen for ipv4; this line is default and implied
+ #listen [::]:80 default_server ipv6only=on; ## listen for ipv6
+
+ root /home/anarcat/public_html/wiki.reseaulibre.ca/;
+ index index.html index.htm;
+
+ # Make site accessible from http://localhost/
+ server_name wiki.reseaulibre.ca;
+
+ location / {
+ try_files $uri $uri/ /index.html;
+ }
+ location /ikiwiki.cgi {
+ fastcgi_pass unix:/tmp/fcgi.socket;
+ fastcgi_index ikiwiki.cgi;
+ fastcgi_param SCRIPT_FILENAME /home/anarcat/public_html/ikiwiki.cgi;
+ fastcgi_param DOCUMENT_ROOT /home/anarcat/public_html/wiki.reseaulibre.ca;
+ include /etc/nginx/fastcgi_params;
+ }
+ }
+
