          php-fpm - PHP FastCGI Process Manager 'PHP-FPM'

          php-fpm [options]

          PHP is a widely-used general-purpose scripting language that
          is especially suited for Web development and can be embedded
          into HTML. This is a variant of PHP that will run in the
          background as a daemon, listening for CGI requests. Output
          is logged to /var/log/php-fpm.log.

          Most options are set in the configuration file. The configu-
          ration file is /etc/php-fpm.conf. By default, php-fpm will
          respond to CGI requests listening on localhost http port
          9000. Therefore php-fpm expects your webserver to forward
          all requests for '.php' files to port 9000 and you should
          edit your webserver configuration file appropriately.
