nginx的server块如何支持php

server
{
    listen 80;
    server_name abc.com;
    index index.html index.htm index.php;
    root /var/www;

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

}
