Please run this command and post the output:

/usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf -v

partofthething commented 3 years ago

I had a similar issue after my ubuntu install auto-updated to 2.0 and if I had to guess this would be because of the change in how letsencrypt certificates are accessed in 2.0. This is helpful: https://mosquitto.org/documentation/migrating-to-2-0/

chanddavid commented 2 years ago

just go on etc/mosquito file open terminal from that location sudo systemctl start mosquitto.service or sudo systemctl start mosquito sudo systemctl status mosquitto.service
this works for me and hope it works for you guys

Hi Guys, I too face this same Issue can anyone help on this.

Hi @Jai123-Jai ,

I sovled my case by deleting extra .conf files under /etc/mosquitto/ folder.

Not sure if that works for your case.

Thanks.

sensir233 commented 1 year ago

image I open another terminal, log in with the same identity, and use systemctl status mosquitto to view the status, and the same situation occurs. At this time, I use ststemctl start mosquitto to display the error of Jop for mosquitto.service failed beacuse... image At this time, I use ps -aux |grep mosquitto to find the corresponding PID value, kill it, and re-enter systemctl start mosquitto to start normally image

Bobo-bug-lab commented 1 year ago

If another process is using the default MQTT port for Mosquitto (typically 1883), the Mosquitto service will fail to start. Try editing the "mosquitto.conf" sudo nano mosquitto.conf If "listener 1883" exists, try change it to other ports and save.

In my case I deployed Azure iot on my devices so there were ports conflits

shubhamnodered commented 6 months ago

How did i solve it in my case!!!!

Problem: image

mosquitto.conf file: image

Steps, i took:

  1. I started with first checking the log file [/var/log/mosquitto/mosquitto.log] using winscp software text editor. Here, i found "server.key" file is creating problem resulting in permission denied [permission error] image

  2. To resolve it, i checked server.key file permission using ls -l command. It was not the issue: image

  3. Next i used, chown command to check and change ownership image

  4. Next i visited mosquitto.conf file to cross-check for server.key path and deleted any extra lines and spaces after server.key path.

  5. Once done, i saved the mosquitto.conf file and restarted mosquitto. To my wonder it worked this time and mosquitto successfully restarted. image

  6. I checked for the mosquitto status: image

Regretfully, i failed during the testing. So, any help would be appreciated. [I am attaching the error and log file] image
