Hi,
I'm not sure what you're exactly trying to do, is it cgi or fastcgi
you want to use?
i managed to get cgi working with fcgi-cgi, yet i didn't figure out how
to make use of fastcgi.
atleast under chroot i was receiving error about prematurely closed
connection while reading response header from upstream.
this was through unix socket. i launched the 'fastcgi processes'
by hand with spawn-fcgi, and saw them die one after another when
trying to access it via browser, to be clear, 1 process died per request,
and i had launched multiple w/-F arg for spawn-fcgi.
i'm not going to try debugging it any further, plain cgi is what i was after.

this is what i was testing plain cgi with, while the above does work,
there is no benefit for the extra w/o fastcgi, needs to be built w/-static:
#include <stdio.h>
int
main(void)
{
printf("Content-type: text/plain\n\n");
printf("req on host %s",
getenv("SERVER_NAME"));
return 0;
}
here is my ngix.conf for testing cgi:
worker_processes 1;
events {
worker_connections 100;
}
http {
include mime.types;
default_type application/octet-stream;
keepalive_timeout 65;
server {
listen 80;
server_name 192.168.2.94;
location = /cgi-bin {
rewrite ^ /cgi-bin/ permanent;
}
location /cgi-bin/ {
fastcgi_index default.cgi;
fastcgi_pass unix:/fcgi.socket;
fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
include fastcgi_params;
}
location / {
root /htdocs;
index index.html index.htm;
}
}
}
