If the following error message is displayed:

[Root @ dev-zhanghua ~] # Systemctl enable rc-local.service
The unit files have no [Install] section. They are not meant to be enabled
Using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
. Wants/or. requires/directory.
2) A unit's purpose may be to act as a helper for some other unit which has
A requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call ,...).

 

Sudo vim/usr/lib/systemd/system/rc-local.service

Add at the end of the rc-local.service file:

[Install]
Wantedbypolicmulti-user.tar get

And re-set the boot start:

Sudo systemctl enable rc-local.service
