Can not make Mosquitto MQTT as services Topic is solved

[G33RT]

Hi,

I installed Mosquitto MQTT as described here:
http://richardn.ca/2018/02/08/installin ... an-debian/

But at the end of the last command to run it as a service "sudo systemctl start mosquitto.service" I receive an error:

root@DietPi:~# sudo systemctl start mosquitto.service
Job for mosquitto.service failed because the control process exited with error code.
See "systemctl status mosquitto.service" and "journalctl -xe" for details.

systemctl status mosquitto.service

When I run it as mosquitto it runs fine but in foreground which I don not want.

Hi,

many thanks for your report. Why are you not using diepi-software to install Mosquitto ?? This would do all needed steps automatically, including setting up the service.

I did that but Mosquitto did not work, after manual install it does work.

Do you have a suggestion to solve this issue ?

[Joulinar]

what exactly was the issue once you installed Mosquitto using diepi-software

I'm fogotten to copy the fail.
But it was something about Mosquitto not starting, than I did an manual install which works but can not get it runnin as a service.

Wat is the best way to completely de-install Mosquitto, via the diepi-software or via command line ?

[G33RT]

I have de-install Mosquitto via the dietpi-software menu.
Then I reinstall Mosquitto via the dietpi-software and reboot.
After the restart no Mosquitto is runnung !

Please advice me what to do to get it running as a service !

What is the error message? Did you check the log file?

[G33RT]

What log file ?

When I try to sudo systemctl start mosquitto.service it says (See "systemctl status mosquitto.service" and "journalctl -xe" for details)

So check my opening post for the systemctl status mosquitto.service output.
