# Worker Node Installation

## Installation

The Worker Node Client contains the tools that need to be on the compute nodes of your cluster. It's typically placed in a NFS mounted directory (in this example /apps/osg) so all nodes will see the same tools. This should not be the same directory as where you CE was installed, although there will be some duplication.

cd /apps/osg
pacman -get http://software.grid.iu.edu/osg-1.2:wn-client
source setup.sh
vdt-postinstall


You may want to coordinate the fetch-crl and vdt-update-certs activities between your CE and Worker Node installation directories. See the remarks in the Compute Element and Batch Scheduler Interface if you want to do this. Otherwise, vdt-control --enable fetch-crl --vdt-update-certs on one system to keep the CA certs and CRLs current in the Worker Node directory.
