Worker Node Client Installation

To install the OSG worker node client software I first mount the desired NFS-mounted filesystem (read-write) on one cluster node. I then create the "wn-client" directory and the following pacman script to download the software: 

VDTSETUP_AGREE_TO_LICENSES=y
export VDTSETUP_AGREE_TO_LICENSES
VDTSETUP_INSTALL_CERTS=l
export VDTSETUP_INSTALL_CERTS
VDTSETUP_EDG_CRL_UPDATE=y
export VDTSETUP_EDG_CRL_UPDATE
VDTSETUP_ENABLE_ROTATE=n
export VDTSETUP_ENABLE_ROTATE
pacman -trust-all-caches -get ITB:wn-client

Then, in order to avoid some confusion with differing $GLOBUS_LOCATION on head node and worker node, I symlink as follows: 

mkdir -p /opt/OSG-0.6/
cd /opt/OSG-0.6/
ln -s /auto/GRID/wn-client-0.6/globus

I also need to set up a cron script on the NFS server to syncronize the signing certificates between the head node and worker node directories: 

#!/bin/sh
rsync -va /opt/OSG-0.6/globus/share/certificates  \
   /auto/GRID/wn-client-0.6/globus/share/certificates
