How to add a script to startup and shutdown in debian?

Question

the title pretty much sums it up.

how do I add a startup.sh and shutdown.sh of my server app to the startup and shutdown sequence of the Debian OS?

Answer 1

On Debian, service & application boot and shutdown scripts should be placed into /etc/init.d/.

Debian provides an example script /etc/init.d/skeleton that you can modify to your taste for your particular application.

Once it's in place, call:

# update-rc.d YOURAPP defaults

To have Debian add the /etc/rc?.d/ symlinks for you.

If you prefer a menu or graphical interface, take a look at the sysv-rc-conf or ksysv package.

Answer 2

You can call your script from /etc/rc.local, prior to the line that says exit 0

As for shutting down your app, I would suggest putting a script in /etc/rc0.d. You need to name it with an uppercase K, and then a 2 digit number which specifies the order these scripts are run, and then a name. It will be called with a parameter "stop", but you can ignore this for a simple stop script.

Answer 3

For startup have a look at this.

For shutdown, create a link / copy your script into one of the /etc/rcX.d folders where X is the runlevel that you want it to execute at. 0 is the shutdown runlevel for Debian I believe.
