systemd stop script

[alfons]

Hello to all,

I'm not new to linux but until now I don't know anything about systemd. I think it is not straight forward to use.......
Questions I have:
- CentOS 7 uses systemd, but I see all the "old" init.d, rc*.d directories. Does that mean it uses both system V and systemd?
- I need to start a script as the server shut's down to shutdown a database first. In the old days I had to use a K* link in the rc*.d directory. Can anyone give an example of the unit script to be used?

Best regards, Alfons
