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.

3. Check your host Vi /etc/hosts (for example) Start ntpd
# Do not remove the following line, or various programs
# that require network functionality will fail.
localhost.localdomain localhost
gilda01.ihep.ac.cn gilda01
Start ntpd
service ntpd stop
ntpdate ntp-1.infn.it
service ntpd start

4. Repository settings
Specify the mrepo host:
export MREPO=
Configure the repository as follows:
REPOS="dag ig glite-generic lcg-ca glite-ui"
Get repositories with:
for name in $REPOS; do wget $MREPO/$name.repo -O /etc/yum.repos.d/$name.repo; done
Copy LCG-CA
wget -O /etc/yum.repos.d/lcg-ca.repo
Copy the gilda utils:
wget -O /etc/yum.repos.d/gilda.repo

5. Edit /etc/yum.repos.d/glite-ui.repo （NOTICE！！）
# This is the official YUM repository string for the glite 3.2 User Interface
# Fetched from:
# Place it to /etc/yum.repos.d/ and run 'yum update'
[glite-UI]
name=gLite 3.2 User Interface
baseurl=
gpgkey=
gpgcheck=1
enabled=1
[glite-UI_updates]
baseurl=
[glite-UI_ext]
baseurl=
gpgcheck=0

6. install by yum generic installation: UI specific Install: Update java
update the host:
yum clean all
update CA:
yum install lcg-CA
install Gilda utils:
yum install gilda_utils
UI specific Install:
install UI:
yum groupinstall ig_UI_noafs
Update java
yum install java

7. get host certificates ready
$# cp hostcert.pem /etc/grid-security/
$# cp hostkey.pem /etc/grid-security/
$# chmod 644 /etc/grid-security/hostcert.pm
$# chmod 400 /etc/grid-security/hostkey.pem

8. edit site-info.def Edit site-info.def:
vi /opt/glite/yaim/examples/siteinfo/ig-site-info.def
RB_HOST=RB_hostname
BDII_HOST=top-BDII-hostname
WMS_HOST=wms-hostname
LB_HOST=“lb-hostname:9000"

VO_GILDA_VOMS_CA_DN="'/C=IT/O=INFN/CN=INFN CA' '/C=IT/O=INFN/CN=INFN CA'"

9. Edit ig-groups.conf
Edit /opt/glite/yaim/examples/siteinfo/ig-groups.conf,
"/gilda/ROLE=SoftwareManager":::sgm:
"/gilda/grelc/das/*":gilda:::
"/gilda"::::
Remove ig.repo （NOTICE！！！）
cd /etc/yum.repo.d
mv ig.repo ig.repo.backup

10. Configuration
/opt/glite/yaim/bin/yaim -c -s /opt/glite/yaim/examples/siteinfo/ig-site-info.def -n glite-UI

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

12. Test UI
login as a non root users to UI and initialize your voms proxy.
$# voms-proxy-init –voms gilda
~]$ voms-proxy-init -voms gilda
Enter GRID pass phrase:
Your identity: /C=CN/O=HEP/O=IHEP/OU=CC/CN=dong xu

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

13. 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 $LFC_HOST
gilda07.ihep.ac.cn
~]$ lfc-ls /grid/gilda/home
xud
~]$ glite-wms-job-delegate-proxy -d xud
