Relocatable Distribution

What is relocatable distribution? can allow you install UI or WN as non-root user.

Provide a tarball containing gLite dependencies which might be missing on your host machine.

supported on SL(C)3 on x86.

also work on SL(C)4 on x86 and x86_64 in compatability mode.

23

Installation

Download the two tarballs from the repository.

Create an INSTALL_ROOT directory for the distribution.

Then cd into this directory and untar both tarballs. As an example :

mkdir /gLite

cd /gLite

tar zxvf glite-UI-3.1.8-0.tar.gz

tar zxvf glite-UI-3.1.8-0-external.tar.gz

24

ConfigurationWhen you are already untar the tarball, just run the configure command:

<INSTALL_ROOT>/glite/yaim/bin/yaim -c -s <your site-info.def> -n UI_TAR

To use the UI TAR you have to source one file (*.sh for bash, *csh for tcsh):

$GLITE_EXTERNAL_ROOT/etc/profile.d/grid-env.(c)sh
