What is a User Interface (UI) ?

How to install a User Interface.

How to configure a User Interface.

Outline


What is a User Interface? The UI is a suite of clients and API that users and applications can use to access the gLite services.

The gLite UI includes the following components:

– VOMS command-line tools– Workload Management System clients and APIs– Logging and Bookkeeping clients and APIs

– Data Transfer command-line clients and APIs– Data Catalog command-line clients and APIs– gLite I/O client and APIs– R-GMA client and APIs


Installing User Interface (UI)


Node Syncronization with NTP Syncronization among all nodes is mandatory. It can be achieved by

the NTP protocol with a time server Install ntp if not already available for your system:

>apt-get install ntp Add your time server in /etc/ntp.conf

• restrict <time_server_IP_address> mask 255.255.255.255 nomodify notrap noquery

• server <time_server_name> • (you can use ntp-1.infn.it – IP 193.206.144.10)

Edit /etc/ntp/step-tickers adding your(s) time server(s) hostname If you are running a firewall, you will have to allow inbound

comminication on the NTP port:-A INPUT -s <NTP-serverIP-1> -p udp --dport 123 -j ACCEPT

Activate the ntpd service with the following commands:>ntpdate <your ntp server name> >service ntpd start>chkconfig ntpd on>ntpq –p

<your ntp server name> =

ntp-1.infn.it


Installation Pre-requisites Start from a fresh install of SLC 3.0.x and verify that apt is installed and properly

configured:>rpm -qa | grep aptInstall apt if necessary:>rpm -ivh

Java SDK is required to install almost any LCG/gLite grid service. Due to license issues, it is not found in the LCG repositories. So please download and install a release of Sun Java SDK >= 1.4.2_08 from http://java.sun.com/j2se/1.4.2/download.html

>chmod +x j2sdk-1_4_2_11-linux-i586-rpm.bin>./j2sdk-1_4_2_11-linux-i586-rpm.bin> rpm -ivh j2sdk-1_4_2_11-linux-i586.rpmPreparing... ###########################################

Security pre-requisites

If you plan to use certificates released by unsupported

EGEE CA’s, be sure that their public key, signing policy

and CRLs (usually distributed with an rpm) are installed

in /etc/grid-security/certificates.

• For the VO GILDA, the RPM is available from

https://gilda.ct.infn.it/RPMS/ca_GILDA-0.28.1.i386.rpm

Install it with the command:

>rpm –ivh ca_GILDA-1.0-1.i386.rpm


Installing User Interface via apt

1. Create the file glite.list in the /etc/apt/sources.list.d directory and put this row on it:

rpm http://211.71.7.254 glite_1.4-i386 1_4 externals updates2. Digit the following commands:

>apt-get update>apt-get dist-upgrade

3. Install User Interface:>apt-get install glite-ui-config

See http://glite.web.cern.ch/glite/packages/APT.asp


Installing User Interface via apt

If the installation is performed successfully, the

following components are installed:

– gLite in /opt/glite

– Globus in /opt/globus

– GPT in /opt/gpt


Installation of VOMS Certificate Install the GILDA's VOMS server host certificates gilda-voms.ct.infn.it.pem, e voms.ct.infn.it.pem, in the

directory /etc/grid-security/vomsdir

Edit the /opt/glite/etc/vomses file as follow:

"gilda" "voms.ct.infn.it" "15001" "/C=IT/O=GILDA/OU=Host/L=INFN Catania/CN=voms.ct.infn.it/[email protected]" "gilda“

Or install the following rpm file:>rpm –ivh glite-voms-vo-gilda-1.0-0.noarch.rpm

(download from http://grid018.ct.infn.it/apt/gilda_app-i386/RPMS/glite-voms-vo-gilda-1.0-

0.noarch.rpm)


User Interface Configuration Configuration comes through the execution of pyhton

scripts, which takes as input XML files. So services have to be configured by editing these XML

files. Attributes in XML file are well commented and

selfexplaining. XML files are provided as templates, under

/opt/glite/etc/config/templates Copy templates file to /opt/glite/etc/config Edit each of them separately. Then we could launch the configurator scripts for the

User Interface.

In order to obtain a correct files configuration, is important to delete from all .XML file the contained string “changeme” and replace it with empty string if necessary.

Configuration Note:


Post configurationIn order to commit configuration, execute the script in

/opt/glite/etc/config/scripts

./glite-uiconfig.py

To assure the correct functionality of the gLite UI it is necessary to add, as root, the following rows in /etc/profile

source /etc/glite/profile.d/glite_setenv.sh

PATH=$PATH:/opt/glite/externals/myproxy-1.14/bin:/opt/lcg/bin:/opt/lcg/sbin

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/glite/externals/myproxy-1.14/lib:/opt/lcg/lib
