LDG Software Installation

The LDG software is packaged as RPMs which are installed using a private database using a wrapper script. It is fully independent of and does not conflict with the system RPM database. No root privileges are required to install the LDG software. A list of available RPMs can be obtained here.

Perform the following steps to initialise the software root and to install a LCG-based Grid UserInterface (GUI):

1. Check that you have at least 90 MBytes of disk space available in your installation directory.
2. Download setup script.
3. Execute the following commands

      # cd <my_install_directory>
      # sh setup
      # LROOT=`pwd`/lroot; export LROOT

   Or equivalently for csh or tcsh:

      # cd <my_install_directory>
      # sh setup
      # setenv LROOT `pwd`/lroot

4. Select the lastest software release (<rel>), the latest RPM release (<rpmrel>), and the required unix version (<unix>). Execute the installation commands:

      # $LROOT/bin/lrpm -i gui-<rel>-<rpmrel>.<unix>.noarch.rpm
      # $LROOT/bin/lrpm -i gui-default-<rel>-<rpmrel>.<unix>.noarch.rpm
      # $LROOT/bin/lrpm -i env.rpm

The Grid User Interface (GUI) is available for the following unix platforms:

To initialise your LDG software environment you always have to execute the following commands:

   # LROOT=<my_install_directory>/lroot
   # export LROOT
   # . $LROOT/etc/env.sh

   # setenv LROOT <my_install_directory>/lroot
   # source $LROOT/etc/env.csh

Note that LROOT should not contain a terminating '/'.

   # lrpm -i cert.rpm
   # lrpm -i jre.rpm ltools.rpm ltools-default.rpm
   # lrpm -i ildg_cksum.rpm ildg_cksum-default.rpm

   # lrpm -U cert.rpm

Test your software installation using the following command:

   # grid-proxy-init

Or if this does not work:

   # grid-proxy-init -key ~/.globus/userkey.pem -cert ~/.globus/usercert.pem
