Overview<\/h2>\n
\n
Warning:<\/div>\n
\n We strongly<\/strong> recommend that you only activate Apache PHP-FPM if your server has at least 2 GB of RAM available, or at least 30 MB of RAM per domain. If you enable PHP-FPM on a server with less than the required RAM, your server may experience severe performance issues.\n <\/div>\n<\/div>\n

PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that allows a website to handle high loads. PHP-FPM maintains pools (workers that can respond to PHP requests) to accomplish this. PHP-FPM is faster than traditional CGI-based methods, such as SUPHP, for multi-user PHP environments. It does not<\/strong> overload a system\u2019s memory with PHP from Apache processes.<\/p>\n

    \n
  • LiteSpeed Web Server uses the lsphp<\/code> binary. LiteSpeed Web Server does not<\/strong> use the system\u2019s PHP-FPM implementation in WHM\u2019s MultiPHP Manager<\/em> interface (WHM >> Home >> Software >> MultiPHP Manager)<\/em>.<\/li>\n
  • To monitor applications that use PHP-FPM, select the Monitor<\/em> checkbox for the PHP-FPM service for cPanel Daemons<\/em> service in WHM\u2019s Service Manager<\/em> interface (WHM >> Home >> Service Configuration >> Service Manager)<\/em>.<\/li>\n<\/ul>\n

    Running PHP-FPM with CentOS 7, CentOS 8, or AlmaLinux 8 and EasyApache 4<\/h2>\n

    On CentOS 7, CentOS 8, and AlmaLinux 8 systems, EasyApache 4 uses the PrivateTmp<\/code> option with PHP-FPM. EasyApache 4 does this to increase security for temporary files that the running processes in PHP-FPM access. The PrivateTmp<\/code> option creates special directories in the \/tmp<\/code> directory for each Apache PHP-FPM version your system uses. It\u2019s possible that each time you or the system restarts the PHP-FPM service, the PrivateTmp<\/code> option will create a new directory.<\/p>\n

    \n
    Warning:<\/div>\n
    \n

    Removing the PrivateTmp<\/code>-created directories, either manually or automatically, will cause errors in applications or websites that use PHP-FPM. We strongly<\/strong> encourage that you do not<\/strong> remove these directories. If you need to remove any of these directories, we recommend that you restart the Apache PHP-FPM service. This ensures that Apache PHP-FPM will work correctly.<\/p>\n

    To restart Apache PHP-FPM, use the following command:<\/p>\n
