    • openHAB version: latest
  • Issue of the topic: Cannot get OpenHAB running

Hi,

my setup runs on a Pi with other goals, so I executed the manual installation as described in the documentation, under Linux (Package Repository Installation) for Apt Based Systems.

wget -qO - ‘https://openhab.jfrog.io/artifactory/api/gpg/key/public’ | sudo apt-key add -
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install openhab
sudo apt-get install openhab-addons
sudo /etc/init.d/openhab start
sudo /etc/init.d/openhab status
sudo update-rc.d openhab defaults
sudo systemctl start openhab.service
sudo systemctl status openhab.service
sudo systemctl daemon-reload
sudo systemctl enable openhab.service

Also changed /etc/default/openhab to other ports (8088 and 8444), to prevent conflicts.

The command sudo systemctl status openhab.service reports:
● openhab.service - openHAB - empowering the smart home

Jul 19 09:16:05 Multi-Pi systemd[1]: Started openHAB - empowering the smart home.`

Which looks fine to me, also Glances reports OpenHAB running.
But even if I wait for hours, the webinterface fails to show.
Scanning ports does also not show ports from OpenHAB active.

Logfiles of OpenHAB in the default locations are all empty.

Hopefully this makes sense to someone?

Regards,

Erwin

What does

sudo netstat -tulpn

especially

sudo netstat -tulpn | grep java

show.

What does

sudo journalctl -u openhab

show ?

Hi Wolfgang, thanks for your reply!

Below the output generated by the commands:
sudo netstat -tulpn

And last the sudo journalctl -u openhab command

Especially the last looks very little to log…

I hope this clarifies where it goes wrong.

Indeed that is less than expected.
Does /var/log/openhab directory exist and is it owned by openhab user as well as the logfile inside the directory ?

Hi Wolfgang,

Below the openhab folder under /var/log:

drwxr-xr-x 2 openhab openhab 120 Jul 18 12:05 openhab

Underlying files exist, but are all 0 bytes.

-rw-r–r-- 1 openhab openhab 0 Jul 18 12:05 audit.log
-rw-r–r-- 1 openhab openhab 0 Jul 18 12:05 events.log
-rw-r–r-- 1 openhab openhab 0 Jul 18 12:05 openhab.log
-rwxr-xr-x 1 openhab openhab 0 Jun 27 22:57 Readme.txt

Are the user rights sufficient?

Regards,

Erwin

yes, they are correct.
