Nagios Support Forum

Hello,
Anyone knows or has any good installation and configuration guide for a mod gearman implementation?
The one in Consol Lab is quite old.

Thanks

SO, I found the below guide:
https://assets.nagios.com/downloads/nag ... ios_XI.pdf

Unfortunately, whenever I install Mod_gearman, I get below error in the end and I can't stop/start it.

Restarting gearmand (via systemctl): Job for gearmand.service failed because a configured resource limit was exceeded. See "systemctl status gearmand.service" and "journalctl -xe" for details.
[FAILED]
Redirecting to /bin/systemctl restart nagios.service
gearmand.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig gearmand on
Redirecting to /bin/systemctl restart mod-gearman-worker.service


Any clues guys?

And, when checking the status:

[root@nagios tmp]# systemctl status gearmand.service

Found the issue within the logs!

ERROR 2021-01-15 10:56:49.000000 [ main ] socket()(Address family not supported by protocol) -> libgearman-server/gearmand.cc:482


Had to modify the /etc/rc.d/init.d/gearmand and add "-L 0.0.0.0" when it start so it only uses ipv4.

start() {
echo -n $"Starting $prog: "
daemon --pidfile=$pidfile --user=gearmand $gearmand -d $OPTIONS -L 0.0.0.0
RETVAL=$?
echo
[ $RETVAL = 0 ] && (touch $lockfile; pgrep -f $gearmand > $pidfile)
return $RETVAL
}
