Install TORQUE (OpenPBS) Server on Goby Head Node¶

yum install pdsh-mod-torque torque-server pdsh-mod-torque torque-libs -y 
/etc/init.d/pbs_server start
/etc/init.d/pbs_sched start

The last command was giving:

pbs_sched: LOG_ERROR::Cannot assign requested address (99) in main, bind

After Googling for answer found this http://www.supercluster.org/pipermail/torqueusers/2009-May/009101.html and changed /etc/sysconfig/network to:

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=goby.amigroup.scripps.edu
GATEWAY=137.131.204.1

Then restarted pbs_server and pbs_sched. Encounter another problem:

[root@goby ~]# pbsnodes
munge: Error: Unable to access "/var/run/munge/munge.socket.2": No such file or directory
pbsnodes: Invalid credential

Run the following commands to fix this:

create-munge-key
chkconfig munge on
/etc/init.d/munge start

* Copy nodes to goby:/var/lib/torque/server_priv and restart /etc/init.d/pbs_server.

[root@goby ~]# cd ~
[root@goby ~]# cat > safadmin
#!/bin/sh

for node in `cat  /var/lib/torque/server_priv/nodes |awk {'print $1'}`
do
  echo "Executing on $node" 
  ssh -oStrictHostKeyChecking=no  $node $@
done
[root@goby ~]# chmod +x safadmin 
[root@goby ~]# ./safadmin ls

This adds RSA key for nodes to the list of known hosts.
