LinuxQuestions.org - Create a systemctl script to start a php file

I just figured out how to write a init.d script to create a daemon which runs a php script, and now found I learned the old way. Wonderful...

That being said, my initial experience with systemctl is good, so upward and onward!

Below is what I came up with (with a lot of help) for the old way.

According to /etc/init.d/README

Quote:

Note that traditional init scripts continue to function on a systemd
system. An init script /etc/rc.d/init.d/foobar is implicitly mapped
into a service unit foobar.service during system initialization.

So, as a quick fix, I added my old init.d to my new server, rebooted, and then executed systemctl enable soaptest (/etc/init.d/soaptest), and it was added the old way.

For a starting point, can I backward-engineer the equivalent systemctl script? I tried using systemctl restart soaptest, but no luck. Will doing so not work?

Code:

#!/bin/sh

### BEGIN INIT INFO

# Provides:          Test SOAP Simulator

# Required-Start:    $local_fs $network $named $time $syslog

# Required-Stop:    $local_fs $network $named $time $syslog

# Default-Start:    2 3 4 5

# Default-Stop:      0 1 6

# Short-Description: Start SOAP Simulator

# Description:      Initiate a given PHP file every 5 seconds to simulate a SOAP server.
