Hi,

you can use /etc/rc.d/rc.local for this, but it is kind of an old fashioned approach.

CentOS 7 custom start up script

If you absolutely want to use rc.local, you have to enable & start rc-local.service. I have not tried this and what I read on internet tells me that this sometimes may give weird and unexpected results. Please do your own research beforehand should you choose to use this. Link

But a better option is to write a customer systemd service for this. I have followed this for my custom startup scripts and it worked for me.
