Mosquitto startet nicht.

Übersetzen und ergänzen!

My Xively feeds stopped working recently which I push to via MQTT and more specifically Mosquitto. After checking the service through the console I kept seeing the following error:

pi@raspberrypi ~/node-red $ sudo service mosquitto start
[ ok ] Starting network daemon:: mosquitto.
pi@raspberrypi ~/node-red $ sudo service mosquitto status
[FAIL] mosquitto is not running ... failed!

So the service is starting and then failing straight away. After a bit of hunting around I noticed there was a mention of the mosquitto.db file causing issues being partially locked/corrupted/non-writeable.

Well the best way I thought was to just remove the file to see what would happen:

pi@raspberrypi ~/node-red $ cd /var/lib/mosquitto/
pi@raspberrypi /var/lib/mosquitto $ ls
mosquitto.db
pi@raspberrypi /var/lib/mosquitto $ nano mosquitto.db
pi@raspberrypi /var/lib/mosquitto $ sudo rm mosquitto.db
pi@raspberrypi /var/lib/mosquitto $ sudo service mosquitto start
[ ok ] Starting network daemon:: mosquitto.
pi@raspberrypi /var/lib/mosquitto $ sudo service mosquitto status
[ ok ] mosquitto is running.
