2. Introductions
The access point to the WLCG/EGEE Grid is the User Interface (UI).
This can be any machine where users have a personal account and where their user certificate is installed.
The gLite user Interface is a suite of clients and APIs that users and applications can use to access the gLite services from both the LCG and gLite software stack.
From a UI a user can be authenticated and authorized to use the WLCG/EGEE resources, and can access the functionalities offered by the Information, Workload and Data Management Systems.

Start ntpd
yum install ntp
chkconfig --list | grep ntp
chkconfig --level 2345 ntpd on
ntpdate ntp-1.infn.it
service ntpd start

priority=45
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-emi

6. Install by yum UI specific Installation: install UI:
yum install EMI-ui

7. edit site-info.def Edit site-info.def:
nano /opt/glite/yaim/etc/site-info.def
chmod -c 755 /opt/glite/yaim/etc/site-info.def
BDII_LIST="xxxxxxx, yyyyyy, zzzzzz"
LB_HOST=xxxxxxxxxxx
PX_HOST=xxxxxxxxxxx
WMS_HOST=xxxxxxxxx
SITE_NAME="AMMAN-GRID"
VOS="gilda"
OUTPUT_STORAGE="/tmp"

8. Configure CA and VO Gilda provides a package with all the necessary
Configure Certification Authority (CA) and Virtual Organization (VO):
wget -O /etc/yum.repos.d/gilda.repo
Yum install gilda_utils
Fixing the VO configuration
1 )
mkdir /etc/grid-security/vomsdir/gilda/
mv /etc/grid-security/vomsdir/voms.ct.infn.it.pem /etc/grid- security/vomsdir/gilda/ 2)
mv /opt/glite/yaim/etc/gilda/vo.d /opt/glite/yaim/etc/gilda

9. /opt/glite/yaim/bin/yaim -c -s /opt/glite/yaim/etc/site-info.def -n UI
Running Yaim
/opt/glite/yaim/bin/yaim -c -s /opt/glite/yaim/etc/site-info.def -n UI

10. Set environment variable LFC_HOST
nano /opt/glite/etc/profile.d/grid-env.sh
gridenv_set “LFC_HOST” “your lfc hostname”

Creating proxy Done
Your proxy is valid until Wed Sep 1 07:25:
~]$

12. Test UI check LFC: $# echo $LFC_HOST $# lfc-ls /grid/gilda/home
$# lfc-mkdir /grid/gilda/home/xud
$# glite-wms-job-delegate-proxy -d xud
~]$ echo $LFC_HOST
gilda07.ihep.ac.cn
