Nginx config file isn't locating my Codeigniter/PHP app

Question

I can't figure out how to make the Nginx config file locate my Codeigniter app. Serving PHP on this server is not the problem b/c if I put a php file in my root directory, I can echo "hello world";.

Here's my Nginx config file which is nearly verbatim from this tutorial. Note that I've manipulated many of these parameters and none had an effext so I'm wondering whether I need to look beyond this file to get it to work?:

server {
    listen   80;
    server_name www.mysite.com mysite.com;
    root   /var/www;
    index index.html index.php index.htm;
    access_log /var/log/nginx/access.log; 
    error_log /var/log/nginx/error.log;  

    location / {
      try_files $uri $uri/ /index.php;
    }

    location ~* \.php$ {
      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      fastcgi_split_path_info ^(.+\.php)(.*)$;
      include fastcgi_params;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

I've been thinking all along this is a simple path issue b/c Codeigniter has a somewhat confusing routing structure but just can't see the problem with my config. Thoughts?

Answer 1

Everything up top matches what I have for a CI project, then this is my location config:

location ~ \.php$ {
   include /etc/nginx/fastcgi_params;
   fastcgi_pass   127.0.0.1:9000;
   fastcgi_index  index.php;
   fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

Not sure if by removing the wildcard * would help, or getting rid of the split_info param...
