Init script example for unoconv on debian

Back to unoconv installation

This script can be installed to /etc/init.d/unoconvd and then linked to system startup with the command:

sudo update-rc.d unoconvd defaults

If you are planning to unoconv service for remote access as described here , notice that it will be listening on localhost interface by default. To make it listen on the different network interface, you need to create /etc/default/unoconv with a content below to override DAEMON_ARGS variable (use specific IP if you have more than one network interface, or 0.0.0.0 to listen on all of them):

# Override arguments to make unoconv listening on network interface.
DAEMON_ARGS="--listener -s 0.0.0.0"

It is also recommended to add this to the root crontab as it is safe to run "sudo service unoconvd start" over and over (it will check if the process is running and start it if required).

Crontab entry to check and start the process every 5 minutes. This version will print a message when unoconv is restarted so that an email will be sent by cron.

Here is the script.
