drupal 6 : nginx configuration and rewrite rule for enabling clean url

To run your drupal site on nginx, the lightweight web server, you will need a custom conf file to make nginx working with php. If you want to enable drupal's clean url function ( maybe you should because a clean url is both more user-friendly and Search Engine friendly ), you will need a additional nginx rewrite rule. I have managed to get drupal 6 working on nginx, and here is what in my nginx configuration file:

server {
    listen       80;
    server_name  www.o-learn.com ; # your domain name
	client_max_body_size 50M;
	root  /wwwroot/www.o-learn.com; # your drupal site files
	
	charset utf8;
	source_charset utf8;
    access_log  /logs/www.o-learn.com.access.log main; # log file path

	# All dynamic requests will go here
	location / {
		root /wwwroot/www.o-learn.com; # your drupal site files
		index  index.php;
		
		if (!-e $request_filename) {
		    rewrite  ^/(.*)$  /index.php?q=$1  last;
		    break;
		}
	}
		
		error_page  404     /index.php;
		# serve static files directly
        location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico)$ {
            access_log        off;
            expires           30d;
        }
		
	  location ~ .php$ {
	                fastcgi_pass   127.0.0.1:9000; #your spawn_fcgi socket 
	                fastcgi_index  index.php;
	                fastcgi_param  SCRIPT_FILENAME   /wwwroot/www.o-learn.com$fastcgi_script_name;  
							# your drupal site file path

	                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_NAME        $fastcgi_script_name;
	                fastcgi_param  REQUEST_URI        $request_uri;
	                fastcgi_param  DOCUMENT_URI       $document_uri;
	                fastcgi_param  DOCUMENT_ROOT      $document_root;
	                fastcgi_param  SERVER_PROTOCOL    $server_protocol;

	                fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
	                fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

	                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;
	        }
}

I hope it can help you. If you meet any problem, you can leave a comment, and I will try what I can to help.
