WHMCS
Lofenta runs WHMCS on a tuned image with OPcache, ionCube, PHP-FPM, and Caddy, so pages load fast. Choose your WHMCS version and PHP version when you deploy, and Lofenta provisions a MariaDB and a Redis and pre-fills the setup. The only thing you add is your license.
Deploying
Pick WHMCS from the templates, then choose a version. 8.13.4 runs on PHP 8.1 or 8.2, 9.0.5 runs on PHP 8.2 or 8.3. PHP 8.2 is the default and the version most WHMCS addons target. Lofenta creates the database and Redis, seeds a clean WHMCS install, and creates your admin account.
Your license
After the app boots, open the admin area with the credentials shown in your project environment variables, then paste your WHMCS license key into the WHMCS_LICENSE_KEY variable and redeploy. The license locks to your app domain on first activation.
Changing PHP later
Change the PHP_VERSION environment variable to another version your WHMCS release supports and redeploy. Your data is untouched.
