Memory Usage PHP-FPM

Hi, I finally recently decided to upgrade from EA3/suPHP (Cloudlinux servers) to EA4 + PHP-FPM. Everything went fine, however one thing was not immediately obvious after the upgrades. Namely certain PHP settings are controlled via PHP-FPM settings such as disable_functions and error_reporting (and many others). You may think that your 'disable_functions' are set correctly via php.ini (multiphp editor in WHM) but they're not. PHP-FPM has its own settings. To ensure that you have disable_functions actually in place for ALL accounts on the server, you will need to follow these steps: 1. Create /var/cpanel/ApachePHPFPM/ ie. "mkdir /var/cpanel/ApachePHPFPM/" 2. Create /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml ie. "touch /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml" 3. Open the above yaml file with your favorite editor ie. pico /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml 4. Enter the following line, exit and save. php_admin_value_disable_functions : phpinfo,dl,passthru,proc_open,proc_close,shell_exec,system,exec,show_source,popen,allow_url_fopen ^^ obviously adjust the list of functions you want to disable. 5. /scripts/php_fpm_config --rebuild That's it...the disable_functions are now in place and actually functional. In my system_pool_defaults.yam I have also added php_admin_value_error_reporting : E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED php_admin_flag_allow_url_fopen : off The error_reporting in particular drove me crazy for days as some older web sites were breaking (due to strict/deprecated error messages) even though my normal php.ini settings were set to disable strict/deprecated. As it turned out, just like the 'disable_functions' issue above, PHP-FPM also uses it's own error_reporting settings. PLEASE NOTE: /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml affects all PHP-FPM users on the system. If you want to only modify a particular user, you can, read
