Не получается настроить nginx + php-fpm для работы с Симфони?

server {
    listen      **.**.186.154:80;

    error_log   /var/log/nginx/domains/mydomain.com.error.log error;

    location / {

        try_files $uri /app.php$is_args$args;

            include         /etc/nginx/fastcgi_params;

    }
