Nginx configs have gotten really short.

gistfile1.nginxconf

server {
	server_name example.com;
	return 301 http://www.example.com$uri;
}

server {
	server_name www.example.com;
	root /var/www/example.com;

	try_files $uri /index.php?$args;

	location /index.php {
		include fastcgi_params;
		fastcgi_pass unix:/var/run/php5-fpm.sock;
	}
}
