Does your version of CentOS have the @reboot crontab option? If it does this is probably easier unless you want to learn how to write systemd files.

Subject: [EXTERNAL] Running a command at startup
On a support forum, I was told that to turn off my board's blue led run:
echo none | sudo tee /sys/class/leds/blue\:heartbeat/trigger
Well, this does not survive a system reboot. So I was told:
Add the off bit to
/etc/rc.local
Add it above "exit 0"
So of course, CentOS is past using rc.local and recommends:
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this fi
So can someone point me to how to make this into a simple systemd service?
thanks
