Exercise 2: Torque Batch System Installation

Install the torque server

 yum install emi-torque-server
 yum install emi-torque-utils

Check if munge is installed and if needed install it

• Check if munge is installed

 rpm -qa |grep munge

• If needed install it

 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

should be something like:

 # 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 <...>
