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
 

• Create a munge key in one of the hosts:

 /usr/sbin/create-munge-key

• Check the munge key ownership

 ls -l /etc/munge/munge.key

• Copy the munge key on all the hosts of the cluster

 cp /etc/munge/munge.key <...>

• Start the munge daemon on these nodes

 service munge start  
 chkconfig munge on
