5. And then, enable one of the php module available from the previous installation. Just execute the following command :
[root@10 html]# sudo systemctl enable --now php-fpm Created symlink /etc/systemd/system/multi-user.target.wants/php-fpm.service → /usr/lib/systemd/system/php-fpm.service. [root@10 html]#
6. Finally, restart the Webserver available to implement the change. In this article, the example is using Apache Webserver. Just execute the following command :
[root@10 html]# systemctl restart httpd [root@10 html]#
