Outline

1. Layout of the site managers tutorial

2. Available servers

3. Shared pre-requisite for gLite 3.0 services

3



Layout

• The installation, the configuration and the eventual troubleshooting of the gLite 3.0 services will be shown in real time by the tutors.

• After each demo service installation you will have time to re-install it by yourself each participant on his own assigned VM

• We are going to install gLite services onto VMware Virtual Machines easy to resume the initial status of the VM for the following service re-installation

useful if you need to re-try the installation due to errors/mistakes/tests

4



Deployment

• Each machine has VMWare Workstation and a

GILDA Base VM image

• The tutors will use a Virtual Machine with

IP 150.214.3.245 - grid25.cica.es

• There is also another server which will be

used as gLite 3.0 repository to speed up

the download of RPMs sunsite.rediris.es local gLite 3.0 repository

5



Access to the VMs

• IP address: 130.206.2.xxx (xxx=221-244)

• Hostname : gridXX.cica.es (XX=1-24)• Username : root

• Password : GildaVM.06(xxx = 1…24)

RUN /root/netconfig command.Introduce your machine number and the network will be configured automatically.

gLite 3.0 software pre-requisites

7



• Start from a fresh install of SLC 3.0.x

• Java SDK is required to install almost any LCG/gLite grid service. Due to license issues, it is not found in the LCG repositories. You can download it from:

• wget http://sunsite.rediris.es/mirror/grid.infn.it/java/j2sdk-1_4_2_14-linux-i586-rpm.bin

chmod +x j2sdk-1_4_2_14-linux-i586-rpm.bin ./j2sdk-1_4_2_14-linux-i586-rpm.bin rpm -ivh j2sdk-1_4_2_14-linux-i586.rpm Preparing... ##################################

Installation Pre-requisites

8



• Request a X509 host certificate for the gLite service you are going to install from a Certification Autority (CA). For example, to get host certificates from the GILDA CA, go to: https://gilda.ct.infn.it/CA/mgt/restricted/srvreq.php

• We requested the certificates for you, you can copy them from: http://sunsite.rediris.es/mirror/grid.infn.it/certificados

• Install host certificates (hostcert.pem and hostkey.pem) in /etc/grid-security. chmod 644 hostcert.pem chmod 400 hostkey.pem

• YAIM is a set of bash scripts used to install and easily configure the gLite middleware on the target machine

• Ensure you FQDN is properly set hostname –f

• Find the latest YAIM and gilda_ig-yaim version at http://www.cern.ch/grid-deployment/gis/yaim/

• Download it using wget from http://sunsite.rediris.es/mirror/grid.infn.it/gilda/

glite-yaim-latest.rpm http://sunsite.rediris.es/mirror/grid.infn.it/gilda/gilda_ig-yaim-3.0.0-22.noarch.rpm

• Install using rpm -ivh glite-yaim-latest.rpm rpm -ivh gilda_ig-yaim-3.0.0-22.noarch.rpm

• All the configuration values to sites have to be configured in a site configuration file using key-value pairs.

• This file is shared among all the different gLite node types. So edit once and keep it in a safe place

• Create a copy of /opt/glite/yaim/examples/siteinfo/gilda_ig-site-info.def template (coming from the lcg-yaim RPM) to your reference directory for the installation (e.g. /root): cp /opt/glite/yaim/examples/siteinfo/gilda_ig-site-

info.def /root/my-site-info.def

• The general syntax of the file is a sequence of bash-like assignments of variables (<variable>=<value>, no spaces are allowed around =).

• A good syntax test for your site configuration file is to try to source it manually running the command: source my-site-info.def

Site Configuration File

Local repository

• We have installed a local repository at RedIRIS, so you have to specify its correct path in my-site-info.def:

OS_REPOSITORY="rpm http://sunsite.rediris.es/mirror/grid.infn.it/rep slc306-i386 os updates extras"

LCG_REPOSITORY="rpm http://sunsite.rediris.es/mirror/grid.infn.it/rep glite_sl3-i386 3_0 3_0_externals 3_0_updates"

IG_REPOSITORY="rpm http://sunsite.rediris.es/mirror/grid.infn.it/rep 3_0_0 utils"

GILDA_REPOSITORY="rpm http://sunsite.rediris.es/mirror/grid.infn.it/rep gilda_app-i386 app 3_0_0"

CA_REPOSITORY="rpm http://sunsite.rediris.es/mirror/grid.infn.it/rep glite_sl3-i386 security”

JAVA_LOCATION="/usr/java/j2sdk1.4.2_14"

12



Middleware installation with YAIM

• We are ready to install the services:

• /opt/glite/bin/gilda_ig_install_node /root/my-site-info.def GILDA_ig_myServiceName

• This command will download and install all the needed packages.

• Now we can configure the node:

• /opt/glite/bin/gilda_ig_configure_node /root/my-site-info.def GILDA_ig_myServiceName
