Impossible de forcer les fichiers PHP Travail "fichier non trouvé"

J'ai installé nginx sur mon VPS, courir sous contrôle CentOS 6.3, et je ne peux pas faire de fichiers PHP.

Voici mon fichier nginx.conf: -

    user  nginx;

        worker_processes  2;



        error_log  /var/log/nginx/error.log warn;

        pid        /var/run/nginx.pid;





        events {

worker_connections  1024;

        }





        http {

        include       /etc/nginx/mime.types;

        default_type  application/octet-stream;



        log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

                                    '$status $body_bytes_sent "$http_referer" '

                                    '"$http_user_agent" "$http_x_forwarded_for"';



        access_log  /var/log/nginx/access.log  main;



        sendfile        on;

        #tcp_nopush     on;



        keepalive_timeout  65;



        #gzip  on;



        include /etc/nginx/conf.d/*.conf;



        fastcgi_buffers 8 16k;

        fastcgi_buffer_size 32k;

        server_names_hash_bucket_size 128;

        server {

        server_name example.org www.example.org;

        listen 198.245.51.xxx;

        root /var/www/forum;

        index index.html index.htm index.php;

        access_log /var/log/virtualmin/example.org_access_log;

        error_log /var/log/virtualmin/example.org_error_log;

        include fastcgi_params;

        fastcgi_param GATEWAY_INTERFACE CGI/1.1;

        fastcgi_param SERVER_SOFTWARE nginx;

        fastcgi_param QUERY_STRING $query_string;

        fastcgi_param REQUEST_METHOD $request_method;

        fastcgi_param CONTENT_TYPE $content_type;

        fastcgi_param CONTENT_LENGTH $content_length;

        fastcgi_param SCRIPT_FILENAME /var/www/forum/$fastcgi_script_name;

        fastcgi_param SCRIPT_NAME $fastcgi_script_name;

        fastcgi_param REQUEST_URI $request_uri;

        fastcgi_param DOCUMENT_URI $document_uri;

        fastcgi_param DOCUMENT_ROOT /var/www/forum;

        fastcgi_param SERVER_PROTOCOL $server_protocol;

        fastcgi_param REMOTE_ADDR $remote_addr;

        fastcgi_param REMOTE_PORT $remote_port;

        fastcgi_param SERVER_ADDR $server_addr;

        fastcgi_param SERVER_PORT $server_port;

        fastcgi_param SERVER_NAME $server_name;

        fastcgi_param HTTPS $https;

        location ~ \.php$ {

                fastcgi_pass           127.0.0.1:9000;

                fastcgi_index          index.php;

                fastcgi_param SCRIPT_FILENAME /var/www/forum/$fastcgi_script_name;

                fastcgi_param DOCUMENT_ROOT /var/www/forum;

                include                 /etc/nginx/fastcgi_params;



        }

        ssl_certificate /home/example/ssl.cert;

        ssl_certificate_key /home/example/ssl.key;

        fastcgi_read_timeout 60;

                        autoindex on;

        }

        }

Je reçois le message suivant chaque fois que j'essaie d'ouvrir www.mydomain.com/index.php ou tout autre fichier php: -
