Introduction
On supported operating systems, EasyApache 4 uses the PrivateTmp option with PHP-FPM. EasyApache 4 does this to increase security for temporary files that the running processes in PHP-FPM access. The PrivateTmp option creates special directories in the /tmp directory for each Apache PHP-FPM version your system uses. It’s possible that each time you or the system restarts the PHP-FPM service, the PrivateTmp option will create a new directory.
These files will use the following naming convention:
/tmp/systemd-private-*-ea-phpXX-php-fpm.service-*/tmp/
Procedure
Please note that removing the PrivateTmp-created directories, either manually or automatically, will cause errors in applications or websites that use PHP-FPM. We strongly encourage that you do not 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.
To restart Apache PHP-FPM, use the following command:
/usr/local/cpanel/scripts/restartsrv_apache_php_fpm --hard
Alternatively, set the session.save_path directive in the local php.ini file to the default value to prevent systemd from creating the private tmp directories.
The following article covers how you can make changes to your php.ini file:
