Debian installation - no init script created

#1

I installed Duplicati on a Debian box but it did not put an init script in /etc/init.d. Shouldn’t it have? I could write my own but would prefer to use one that came with the .deb package.

Are you using systemd ?
If so, there is no init.d script, instead there is a duplicati.service file:

You activate it with something like:

systemctl enable duplicati

You might also find some useful examples in one of these posts - I know they’re about ReadyNAS installs, but it is Debian based and they do include init.d examples:

Nope I’m still using sysvinit. My Debian install is about 5 years old, but I am on testing so most stuff is modern, just haven’t switched to systemd.

Ok so I’m gonna start with something like this… saved as /etc/init.d/duplicati, chmod 755, update-rc.d duplicati defaults, yadda yadda.

(edit: removed script - see better one below)

I believe you can just use commands like enable, disable, start, and stop as described here:

Ok I enhanced this with the ability to stop the service. Also checks to see if the service is already running so it doesn’t attempt to start it again. Maybe this can help out some other people…

@drwtsn32 Would you mind if I include this script in the packages as an example?

You can add a “example script written by Rod” if you want.

Thanks for this script.
I would like to know your name to add it to the start script as a comment with the name of the author
