Overriding or extending the configuration

If you want to augment of replace the configuration of Nginx, PHP or FPM, there are multiple options:

• Place one or more configuration files in specific directories to augment the configuration
• If that does not suit your needs, you can also simply overwrite the configuration files altogether

These are the files to add or overwrite in order to configure the different parts of the webstack:

Application	Copy files into this directory	Overwrite this file if needed
PHP core directives (8.1)	/etc/php81/conf.d/	/etc/php81/php.ini
PHP-FPM (8.1)	/etc/php81/php-fpm.d/	/etc/php81/php-fpm.conf
Nginx	/etc/nginx/conf.d/	/etc/nginx/nginx.conf
Supercronic	-	/etc/supercronic/crontab
