2. In order to prove that the Apache Webserver can execute a webpage with a PHP script exist in it, just create a new file containing the following line :
<?php phpinfo(); ?>
Save the file in the root folder or root document of the Apache Webserver. Normally, it exists in ‘/var/www/html’. So, just save it in a file with the name of ‘phpinfo.php’ for an example. So, the full complete file exist in ‘/var/www/htm/phpinfo.php’.
3. Execute the file in a Web Browser application. If the installation of the PHP module is a success in an Apache Webserver, the following page will appear :
4. Last but not least, execute the following command to persist or to auto start the Apache Webserver’s service every time the operating system starts :
root@hostname:~# systemctl enable apache2 Synchronizing state of apache2.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable apache2 root@hostname:~#
