<xterm2>
[user@grow-grid gLite-UI]$ sudo ./glite/yaim/bin/yaim -c -s site-info.def -n UI_TAR
</xterm2>

Make sure that the gridenv_set is as follows.
<xterm2>
[user@grow-grid gLite-UI]$ sudo vi /share/osg/ce/glite/gLite-UI/external/etc/profile.d/grid-env.sh
</xterm2>
<file bash "/share/osg/ce/glite/gLite-UI/external/etc/profile.d/grid-env.sh">

</file>

===== CRAB Installation =====
==== Directory Setup ====

Create a directory to be network mounted for CRAB.
<xterm2 root>
[root@grow-grid ~]# mkdir /export/crab
</xterm2>

On the head node edit auto.share to mount the crab directory in /share. Add the following line.
<xterm2 root>
[root@grow-prod ~]# vi /etc/auto.share
</xterm2>
<file bash "/etc/auto.share">
crab grid-0-0.local:/export/crab
</file>

Reset 411, and restart nfs service
<xterm2 root>
[root@grow-prod ~]# cd /var/411; make
[root@grow-prod ~]# service nfs restart
</xterm2>

[[http://cmsdoc.cern.ch/cms/ccs/wm/scripts/Crab/]]\\

  - Change directory to crab.
  - Download the CRAB tarfile.
  - Unpack the tar file.
  - Create a soft link to the version directory.
  - Change directory to CRAB version.
  - Run the configuration script.

<xterm2 root>
[root@grow-grid ~]# cd /export/crab
[root@grow-grid crab]# wget "http://cmsdoc.cern.ch/cms/ccs/wm/www/Crab/Docs/CRAB_2_7_8_patch1.tgz"
[root@grow-grid crab]# tar -xzvf CRAB_2_7_8_patch1.tgz
[root@grow-grid crab]# ln -s CRAB_2_7_8_patch1 current
[root@grow-grid crab]# cd CRAB_2_7_8_patch1
[root@grow-grid CRAB_2_7_8_patch1]# ./configure
</xterm2>

Add the following lines to condor_config.local (if they do not already exist) to allow users to use "scheduler=condor_g" in CRAB.
<xterm2>
[user@grow-in0 ~]$ sudo vi /opt/condor/etc/condor_config.local
</xterm2>
<file text "/opt/condor/etc/condor_config.local">
