2.23.12. PHP-FPM

Attention!

PHP-FPM is only available on businesshosting.

PHP—FPM (FastCGI Process Manager) is an alternative implementation of FastCGI mode in PHP. In conjunction with nginx, it provides a higher request processing speed than the default nginx + Apache bundle.

  • Can be used PHP version not lower than 7.0.
  • .Htaccess rules don't apply.
  • PHP-FPM processes are constantly running and consume memory, which is counted in the hosting account quota. With a large number of concurrent requests, a large amount of RAM may be required.
  • PHP only processes files with the extension .php.
  • The standard index file is index.php... For comparison: on request to /html/ Apache will return the contents of the file /html/index.htmlif it exists, and PHP-FPM in such a situation will return a 403 error if the directory /html/ exists, or will send a request to /index.phpif directory /html/ does not exist. When choosing configuration PHP-FPM "Dokuwiki" the standard index file will be doku.php.
  • Routes are configured as follows:
    • If the call goes to a specific file with the extension .php — this file is launched (for example, a request to /path/test.php runs the file /path/test.phpif no such file exists — an error is returned "File not found").
    • If the call goes to URL existing directory — starts index.php from that directory (for example, a request to /wp-admin/ runs the file /wp-admin/index.phpif file index.php not in directory — error 403 is returned).
    • All other requests are redirected to /index.php (requested URL will be available in $_SERVER['REQUEST_URI']).

After changing the web server to PHP-FPM, it becomes possible to select one of the available configuration options:

  • "Default" — no special settings, all requests are redirected to /index.php... Suitable for CMSthat do not require specific settings, for example Joomla! or Octoberas well as frameworks Symfony and Laravel.
  • "Wordpress" — currently the same as "Default"... Perhaps, special settings will be added in the future.
  • "Opencart" — CNC support in format OpenCart.
  • "Dokuwiki" — index file doku.php insteadof index.php, support for CNC format DokuWiki, blocking access to directories /conf/, /bin/, /inc/ and file /install.php.
  • "ModX" — CNC support in format MODX.
  • "Moodle" — support URL ofthekind /index.php/path for Moodle.
  • "PrestaShop" — Support for CNC format PrestaShop.
