How to Install Apache with PHP-FPM on Debian 10

PHP Installation

For the PHP installation we recommend to use Ondřej Surý‘s PPA, which provides latest PHP versions for Debian systems. Add this PPA to your Debian system using the following commands:
wget -q https://packages.sury.org/php/apt.gpg -O- | sudo apt-key add -
sudo echo "deb https://packages.sury.org/php/ buster main" | tee /etc/apt/sources.list.d/php.list
After that, install the required PHP version. You can simply execute the following commands for the default PHP version installation with PHP-FPM packages.
apt update
sudo apt install php php-fpm
Note:- When you are using PHP-FPM. All the PHP modules configurations are residing under /etc/php/7.3/fpm/ directory. You can read more about enable/disable PHP modules.

After installing the above packages php7.3-fpm service will automatically be started. You can make sure by typing below command on terminal.
sudo systemctl status php7.3-fpm
