Issue with Thruk

[Adi Adithya]

Hello Team,

We are seeing issues with thruk where thruk is configured on a cluster where its accessible on one node of the cluster but not on the other node. and we are seeing the below errors from the thruk log:

You need to fix the permission issues. There is nothing anyone can help you. Check the permissions of the folders mentioned in the error.

Cheers,

Hi Sven,

Thanks for the response.

Could you let us know if the thruk.log should be owned by thruk or apache? And should we give 775 as the permission?

Thanks  & Regards,
Adith

There is no "thruk" user. Everything runs as apache user, so the logfiles and folders should be owned by the apache user.

Hi Sven,

We have two node cluster setup for thruk. Thruk.log wont get updated after Oct 22nd. When we do a curl to the localhost, apache webserver comes up. We think the linking between has some issues, that needs to be fixed.
I made changes thruk.log by giving the 775 permissions, and these are the below errors. We have also used thruk user instead of apache as it was redirected from apache user to thruk user.

[thruk]# tail -f thruk.log
