Re: Thruk reports /var/tmp/live.sock: No such file or directory inspite of the file being present (Apache Users)

If apache is supposed to interact with that socket file, the user it runs as at least should be in the nagios group looking at how you configured its permissions, or you could change its ownership to nagios:www-data (or however the user httpd uses is named)

Hi Daniel

I am still seeing

No Backend available

None of the configured Backends could be reached, please have a look at the logfile for detailed information and make sure the core is up and running.

Hi,

I am running thruk (version is thruk-2.12-1.x86_64) which is a web interface for nagios 4.2.3 and running httpd-2.4.6-40.el7.centos.4.x86_64 on CentOS Linux release 7.2.1511 (Core)

While accessing thruk web interface http://thruk.mydomain.com/thruk/cgi-bin/status.cgi?host=all&_=1480078344275

I am seeing this issue in thruk.log prod: ERROR: failed to open socket /var/tmp/live.sock: No such file or directory

#ls -l /var/tmp/live.sock
srw-rw---- 1 nagios nagios 0 Nov 25 18:12 /var/tmp/live.sock

I can share the /etc/httpd/conf.d/thruk.conf

Any help will be highly appreciable.

Regards,

Kaushal
