Init Skript für Debian
Zurück zur Installation von unoconv
Dieser Artikel beschreibt ein Skript, das Sie beim Booten von Debian-Systemen verwenden können, um einen unoconv-Listener zu starten. Das Skript kann unter /etc/init.d/unoconvd gespeichert und wie folgt in den Boot-Prozess eingebunden werden:
sudo update-rc.d unoconvd defaults
Wenn Sie den unoconv-Service auf einen anderen Server auslagern wollen (wie hier beschrieben), dann "lauscht" der Prozess standardmäßig auf localhost. Damit er auf einem anderen Netzwerk-Interface lauscht, müssen Sie eine Datei /etc/default/unoconv mit dem unten stehenden Inhalt anlegen und die Variable DAEMON_ARGS überschreiben (verwenden Sie die spetzifische IP-Adresse, wenn Sie mehr als ein Netztwerk-Interface haben oder verwenden Sie 0.0.0.0, um auf allen Netzwerk-Interfaces zu lauschen):
# Override arguments to make unoconv listening on network interface. DAEMON_ARGS="--listener -s 0.0.0.0"
Außerdem empfehlen wir, folgende Zeile in der root crontab zu ergänzen. Damit wird der Prozess alle 5 Minuten gestartet und beim Neustart von unoconv erhalten Sie vom Cron-Job eine E-Mail.

Hier kommt das Skript:
