SCore System Installation on Compute Hosts
other than Red Hat and SuSE

1. Set up networking
   /root/.rhosts and the /etc/hosts.equiv files must contain all server and compute host names so that the rsh command works on all hosts. For example,

   server.pccluster.org
   comp0.pccluster.org
   comp1.pccluster.org
   comp2.pccluster.org
   comp3.pccluster.org
   

2. Edit /root/.bashrc on all hosts so that the following line is added:

   export PWD
   

3. Copy commands and files
   To copy comands and files, issue the following commands:

   	# mkdir /opt/score
   	# cd /opt/score
   	# rcp server:/etc/score.conf /etc
   	# rsh server 'cd /opt/score;tar cf - deploy install pbs/*/bin pbs/*/sbin'| tar xf -
   

   Or NFS mount server's /opt/score as following commands:

   	# mkdir /opt/score
   	# mount server:/opt/score /opt/score
   

4. setup Device files and daemon
   To create the PM device files and setup daemon, issue the following commands:

   	# cd /opt/score/install/bin.*
   	# ./setup -score_comp -pbs_comp
   	# chkconfig --add scoutd
   

   Edit the /etc/rc.d/init.d/pm_ethernet file if the machine has more than one ethernet card and you want to use a PM/ethernet device other than the eth0 device, modify the IF variable in the file. For example, if you want to use the eth1, the IF variable should be:

   	IF=eth1
   

   To start daemons, issue the following commands:

   	# (cd /etc/rc.d/init.d;./pm_ethernet start)
   	# (cd /etc/rc.d/init.d;./pbs_mon start)
   	# (cd /etc/rc.d/init.d;./scoopd start)
   	# (cd /etc/rc.d/init.d;./scored start)
   

5. Create the /var/scored and /var/scored/scoreboard directories on all hosts
   The /var/scored/singleuser and /var/scored/multiuser directories must be created on all hosts. If you created a /scored file system, then execute:

   	# chmod 755 /scored
   	# ln -s /scored /var/scored
   	# mkdir /var/scored/scoreboard
   	# mkdir /var/scored/singleuser
   	# mkdir /var/scored/multiuser
   	# chmod 777 /var/scored/scoreboard
   	# chmod 1777 /var/scored/singleuser
   	# chmod 755 /var/scored/multiuser
   

   Otherwise,

   	# mkdir /var/scored
   	# chmod 755 /var/scored
   	# mkdir /var/scored/scoreboard
   	# mkdir /var/scored/singleuser
   	# mkdir /var/scored/multiuser
   	# chmod 777 /var/scored/scoreboard
   	# chmod 1777 /var/scored/singleuser
   	# chmod 755 /var/scored/multiuser
   

6. PBS/SCore
   See PBS/SCore Administrator's Guide if you want to use PBS/SCore.
