Run the command below first:

sudo nano /etc/systemd/system/xampp.service

If you have gedit, you can use gedit instead of nano

Copy and paste the code below into the text editor and save

[Unit]
Description=XAMPP
[Service]
ExecStart=/opt/lampp/lampp start ExecStop=/opt/lampp/lampp stop
Type=forking
[Install]
WantedBy=multi-user.target

Now run the command below to check the service status.

systemctl status xampp.service

If it’s not running you can start the service like below:

systemctl start xampp

You can use stop instead of start if you’d like stop xampp service, then start with start command.

And when you want to restart xampp (restarts both apache and mysql) you can run:

systemctl restart xampp

That’s all.
