Resolution for ERROR: torque.setup: line 45: pbs_server: command not found

# ./torque.setup root
initializing TORQUE (admin: root@headnode.com)
./torque.setup: line 45: pbs_server: command not found
ERROR: pbs_server failed to start, check syslog and server logs for more information

Resolution is very simple for this. Th reason for the error as indicated above is that the torque.setup was not able to find the path for pbs_server. Just do the following

# touch /etc/profile.d/torque.sh
vim /etc/profile.d/torque.sh
export PATH=$PATH:/opt/torque/x86_64/bin:/opt/torque/x86_64/sbin

# source /etc/profile.d/torque.sh 

Try ./torque.setup root again. It should work
