How to Enable and Customize PHP-FPM Directives/Pool for a Domain or Server Wide :: cPanel

What is PHP-FPM?

PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that makes a website capable of handling strenuous loads. By setting specific amounts of resources, it even allows a host to process a domain’s requests. To accomplish this, the PHP-FPM maintains “pools” (workers available to respond to PHP requests) where these “pools” of workers allow the website to handle more requests than it normally could.

PHP-FPM is faster than traditional CGI-based methods such as SUPHP for multi-user PHP environments. It does not overload a system’s memory with PHP from Apache processes as ruid2+php-dso does. This method is useful when a user receives extra traffic that requires resources to process it. For example, your website may receive a spike in traffic after a TV show features it or is linked from a popular website.

Forcefully refreshing disk space usage directly from cPanel

If user disk space usage is reflected incorrectly in cPanel, there is a way to force refresh the disk quota of cpanel directly from cPanel.

We will be able to remedy this by refreshing the cPanel cache for this user. This can be done by removing the /home/username/.cpanel/datastore directory, which will be recreated upon the next access of that account’s cPanel.

1. Login to cpanel->file manager -> ensure show hidden file is enabled.
2. Go to /home/username/.cpanel
3. Rename datastore/ to something else
4. Then click disk space usage, it will force refresh the usage
