After configure an .sh with chkconfig, systemctl says unit myservice not found

I'm doing some labs for test setups... I've developed a bash script to set it to autostart using systemd. I installed chkconfig and configured my script as follows: Using root: cd /mypath cp myscript.sh /etc/init.d/ cd /etc/init.d chkconfig --add myscript.sh chkconfig myscript.sh on systemctl start myscript I'm receiving: Unit myscript.service could not be found.
