Mosquito fails to start Topic is solved

[Nizzel]

Hi all
Hoping you can help. I’ve installed several bits of software but one of the main ones I want is Mosquito. I don’t have a lot of Linux experience and have spent a lot of time googling this to no avail.

Here is as much information as I can find to give you:

RPi 3 Model B (armv7l)

Hi,

Pls can you post output of following

Code: Select all

journalctl -u mosquitto.service

[Nizzel]

This is all I got:

-- Logs begin at Sat 2020-04-04 09:53:07 BST, end at Sun 2020-04-05 23:00:15 BST. --
-- No entries --

[Joulinar]

can you try to restart your whole system. Once done pls check mosquitto log file

Code: Select all

cat /var/log/mosquitto/mosquitto.log

[Nizzel]

cat: /var/log/mosquitto/mosquitto.log: No such file or directory

[Joulinar]

can you try running the following command manual to start mosquitto.

Code: Select all

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

[Nizzel]

Thanks for the help. I get this:

1586180857: Error: Unable to open log file /var/log/mosquitto/mosquitto.log for writing.

[Joulinar]

pls can you have a look if the log directory is existing

Code: Select all

ls -la /var/log/

[Nizzel]

I can't see it:

Well than you would need to create the missing log folder

Code: Select all

mkdir /var/log/mosquitto
chown mosquitto /var/log/mosquitto
chmod 755 /var/log/mosquitto

than try to start mosquitto manuell again
