As the file says, it is highly advisable to create your own systemd
service to replace what you put in /etc/rc.d/rc.local (the actual
location, /etc/rc.local should be a symlink to /etc/rc.d/rc.local).  

/etc/rc.d/rc.local still works under CentOS7.  You can continue to use
it, however you'd be better served creating a systemd service unit.
Look at the documentation here:
http://www.freedesktop.org/software/systemd/man/systemd.service.html

Depending on what you're doing, you could probably use a service with
Type=oneshot.  You might want to tell it to also add a
Requires=network-online.target, since judging from the name of the
script, it needs networking to be active.
