yum install munge
Enable munge on your torque cluster
- Check if munge is running
ps -ef |grep munge
Should be something like:
# ps -ef |grep munge munge 26535 1 0 Aug21 ? 00:00:02 /usr/sbin/munged
if not, start munge
service munge start
- Check if munge is set to automatically start at boot time
chkconfig --list |grep munge

# chkconfig --list |grep munge munge 0:off 1:off 2:on 3:on 4:on 5:on 6:off
if not, configure it:
chkconfig munge on
- Check if a munge key is present with right ownership and permissions
ls - /etc/munge/munge.key
should be:
-r-------- 1 munge munge 1024 Aug 14 16:21 /etc/munge/munge.key
if not so,
- create a munge key in one of the hosts:
/usr/sbin/create-munge-key
- set right permissions and ownership:
chown munge:munge /etc/munge/munge.key chmod 400 /etc/munge/munge.key
- Copy the munge key on all the hosts of the cluster
cp /etc/munge/munge.key <...>
