Automatically starting oneshot service on bootup

I have a oneshot service which I want to start at boot time on rhel 7.4.

I understand that "chkconfig --add" is one way to achieve this. But it requires the startup script to be present in

/etc/init.d directory

For non-oneshot services, I understand that the "Restart=" option could be used in the systemd service file.

If I try to set Restart=always for a oneshot service, it doesn't work. Oneshot service needs "Restart=no".

Is there any way I can start a oneshot service upon boot without having the script in

/etc/init.d directory

First of all, since we have not mentioned your Systemd service, here an example:

Example filename:

/etc/systemd/system/my-startup-script.service

Example content:

[Unit]
Description=My startup script
#After=network.target

[Service]
Type=oneshot
ExecStart=/root/my-startup-script.sh
RemainAfterExit=true

[Install]
WantedBy=multi-user.target

After that, just enable it:

systemctl daemon-reload
systemctl enable my-startup-script

In this way you have enabled your service. So, after every reboot, your oneshot service (or whatever normal service) will be executed.

That's all my friend!

"systemctl enable" takes care of starting any service, be it oneshot or other.
