I recently setup MQTT on my OpenHab system and everything is working fine. My only problem is that I am unable to get the mosquitto program to start at boot. I run OpenHab and the Mosquitto on my computer running Ubuntu 16.04. I installed the Mosquitto program using openhabian-config. I tried to do the “sudo systemctl enable mosquitto.service”, but it didn’t work. Here is the message I got:
Synchronizing state of mosquitto.service with SysV init with /lib/systemd/systemd-sysv-install…
Executing /lib/systemd/systemd-sysv-install enable mosquitto
Failed to execute operation: Bad message
The only way I can get it to start is to open a terminal screen when my computer starts up and type “mosquitto” to get it to run.
Any help to get mosquitto to start automatically when the computer is started would be greatly appreciated.
Thanks!
Maybe it will suffice to paste this file into /etc/systemd/system/mosquitto.service and afterwards do a
sudo systemctl daemon-reload
But be aware that a script mosquitto.service is already at your system, so you will have to remove the autogenerated file first. Or maybe as a first step, take a look at /etc/init.d/mosquitto This script should start and stop mosquitto without problems:
Hi Udo_Hartmann
Thanks for helping me trying to fix this problem. I copied your script to my system and issued the command “sudo systemctl daemon-reload”. I rebooted but still mosquitto is not starting automatically at boot up.
I then took a look at the script in “/etc/init.d/mosquitto” this is what it contains:
GNU nano 2.5.3 File: mosquitto
#! /bin/sh

exit 1

I issued the command “sudo /etc/init.d/mosquitto start” . It didn’t seem to work. My raspberry pi logs are saying: “Starting MQTT broker connection 'broker” repeatedly.
Any other ideas?
Well, this is a bit different to the debian script:
udo1toni@openhab2:~$ cat /etc/init.d/mosquitto

just as a guess… Maybe /lib/lsb/init-functions has set init_is_upstart to true (should be false as ubuntu 16.04 should use systemd)?
Where do I set it init_is_upstart to false?
I did find this in /lib/lsb/init-functions file:
# If the currently running init daemon is upstart, return zero; if the
# calling init script belongs to a package which also provides a native
# upstart job, it should generally exit non-zero in this case.
init_is_upstart()
{
if [ -x /sbin/initctl ] && /sbin/initctl version 2>/dev/null | /bin/grep -q upstart; then
return 0
fi
return 1
}
(at least from start and stop block) to evaluate if this solves your problem. It is best practice to make a backup of the file before change it
If mosquitto starts without errors, you should investigate why the function init_is_upstart does return the wrong value. I would strongly recommend not to change the function itself, because there are many scripts which rely on the function.
Udo,
I don’t really know Ubuntu that good and I am not sure I want to risk messing up my OpenHAB system by making all these changes. I think I’ll stay with my current setup. I appreciate you trying to help me.
Thanks.
This script should start and stop mosquitto without problems:
