Tune PHP-FPM pools (pm.max_children) for your RAM
Size PHP-FPM to your server's memory. Choose between dynamic, ondemand and static, calculate pm.max_children from real per-process memory, set pm.max_requests, and act on the max_children warning.
Update DirectAdmin and server software with CustomBuild
Use CustomBuild in DirectAdmin to update Apache, Nginx, LiteSpeed, PHP, MariaDB, Exim and Dovecot, install extra PHP versions and keep DirectAdmin itself current.
Upgrade PHP to a newer version on your VPS
Upgrade a site from PHP 8.1 to 8.3 or 8.4 safely. Install the new PHP-FPM and matching extensions, carry over php.ini changes, switch Nginx or Apache, test, and remove the old version.
Use a different PHP version per website in Nginx
Run each Nginx site on its own PHP version by pointing its server block at a different PHP-FPM socket, give each site a separate pool, and confirm the version without leaving phpinfo exposed.
Use Composer for PHP packages on cPanel hosting
Run Composer on cPanel shared hosting: check it is available, pick the right PHP version, install and update dependencies, handle memory errors and deploy without dev packages.
Use LiteSpeed Cache on any PHP site with .htaccess rules
Cache pages of a custom PHP site or an app without an LSCache plugin using LiteSpeed rewrite rules in .htaccess, with safe exclusions for logged-in users and carts.
Use PHP OPcache on cPanel hosting with CloudLinux PHP Selector
What PHP OPcache does, how to check it is enabled in CloudLinux PHP Selector, sensible OPcache options for WordPress, and how to clear it after deploying code.
WordPress Site Health explained: fix the common warnings
Understand WordPress Site Health status and info: what each common critical issue and recommendation means on cPanel hosting, and how to fix or safely ignore it.
wp-config.php explained: the settings that matter
