GLite on Nikhef Desktops

Notes on how to install the gLite UI tarball for Nikhef desktop use

Download the tarballs from the glite website:

• glite 3.1: http://glite.web.cern.ch/glite/packages/R3.1/updates.asp
• glite 3.2: http://glite.web.cern.ch/glite/packages/R3.2/sl5_x86_64/updates.asp

Make sure to download both the glite-UI tarball itself and the glite-UI-externals tarball.

Extracting the tarballs

• Log in as the user 'gridadm' on a Nikhef desktop, login.nikhef.nl (SL4) or login2.nikhef.nl (SL5)
• Go to the global installation directory

cd /global/ices/lcg

• Create a directory for the new tarball and 'cd' into it,

mkdir glite<VERSION>
cd glite<VERSION>

where <VERSION> denotes the full version number of the glite update, e.g. 3.1.35

• Unpack the tarballs

tar xzf .../glite-UI-<VERSION>-0.tar.gz
tar xzf .../glite-UI-<VERSION>-0-external.tar.gz

Configuring using Yaim

• Copy a site-info.def from a previous installation

cd /global/ices/lcg/glite<VERSION>
export INSTALL_ROOT=$PWD
cp -rp ../glite3.1.35/site-info.def ../glite3.1.35/vo.d .

• Modify the INSTALL_ROOT variable to point to the new version
• Run Yaim

$PWD/glite/yaim/bin/yaim -c -s $PWD/site-info.def -n UI_TAR

Cleaning up after Yaim

There are a few things that need to be cleaned up/correct after a default Yaim configuration:

• use the correct grid-security directory

cd $INSTALL_ROOT
mkdir etc
cd etc
ln -fs ../../grid-security
cd $INSTALL_ROOT/external/etc
rm -rf grid-security
ln -fs ../../../grid-security

(not complete yet)

• copy over correct grid-env scripts from previous release
• copy over glite_wms*conf files from bosui

Testing the new installation

• Load the environment first

. /global/ices/lcg/glite<VERSION>/etc/profile.d/grid-env.sh

and watch for any warnings/errors

• Generate a proxy

voms-proxy-init -voms pvier

• Delegate your proxy to the WMS

glite-wms-delegate-proxy -d $LOGNAME.test

• Do a job list match:

glite-wms-job-list-match -d $LOGNAME.test HelloWorld.jdl
