+To run CGI under nginx, you need to use a FastCGI wrapper. The wrapper must be started somehow just like any other FastCGI program. You can 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`. You may also need to make this file writable by the webserver, if that's running as a different user, e.g.:
+
+ chmod a+w /tmp/fcgi.socket
+
+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;
+ }
+ }
+
+Also, note that the `/tmp/fcgi.socket` file needs to be writable by the webserver. I am also unsure as to the security of this setup, as I am using this only on my dev server. Needless to say that [[real fastcgi support|todo/fastcgi_or_modperl_installation_instructions]] would be great. ;) --[[anarcat]]
