  1. Introduction to the tutorial for site managers Vanessa Hamar Universidad de Los Andes – Mérida, Venezuela Nine EELA Tutorial for Managers and Users Bogotá, 05 - 09 March 2007

  2. Outline • Layout of the site managers tutorial • Available servers • Shared pre-requisite for gLite 3.0 services 9th EELA Tutorial, Bogotá, 05-09 March 2007

  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 9th EELA Tutorial, Bogotá, 05-09 March 2007

  4. Deployment • Each machine has VMWare Player/Workstation and a GILDA Base VM image • There is also another server which will be used as gLite 3.0 repository to speed up the download of RPMs • mnto04.uniandes.edu.co local gLite 3.0 repository 9th EELA Tutorial, Bogotá, 05-09 March 2007

  5. Access to the VMs • IP address: 157.253.42.xxx • Hostname : eventogridxx.uniandes.edu.co • Username : root • Password : GildaVM.06 (xxx = 121…170) 5 9th EELA Tutorial, Bogotá, 05-09 March 2007

  6. gLite 3.0 software pre-requisites 9th EELA Tutorial, Bogotá, 05-09 March 2007

  7. Installation Pre-requisites • 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. • chmod +x j2sdk-1_4_2_13-linux-i586-rpm.bin • ./j2sdk-1_4_2_13-linux-i586-rpm.bin • rpm -ivh j2sdk-1_4_2_13-linux-i586.rpm • Preparing... ################################## [100%] • 1:j2sdk ################################## [100%] 9th EELA Tutorial, Bogotá, 05-09 March 2007

  8. Security pre-requisites • 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 9th EELA Tutorial, Bogotá, 05-09 March 2007

  9. We requested the certificates for you, you can copy them from: • http://mnto04.uniandes.edu.co/certs • Install host certificates (hostcert.pem and hostkey.pem) in /etc/grid-security. • chmod 644 hostcert.pem • chmod 400 hostkey.pem 9th EELA Tutorial, Bogotá, 05-09 March 2007

  10. Security pre-requisites (II) • 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-1.0-6.i386.rpm 9th EELA Tutorial, Bogotá, 05-09 March 2007

  11. Node Synchronization with NTP • Syncronization among all gLite 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 • Activate the ntpd service with the following commands: • ntpdate <your ntp server name> • service ntpd start • chkconfig ntpd on • You can check ntpd’s status with: • ntpq -p 9th EELA Tutorial, Bogotá, 05-09 March 2007

  12. YAIM Installation • 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://grid-deployment.web.cern.ch/grid-deployment/gis/yaim/glite-yaim-3.0.0-34.rpm • http://grid018.ct.infn.it/apt/gilda_app-i386/utils/gilda_ig-yaim-3.0.0-27.noarch.rpm • Install using • rpm -ivh glite-yaim-3.0.0-34.rpm • rpm -ivh gilda_ig-yaim-3.0.0-27.noarch.rpm 9th EELA Tutorial, Bogotá, 05-09 March 2007

  13. Site Configuration File • 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/gilda_ig-site-info.def template (coming from the glite-yaim RPM) to your reference directory for the installation (e.g. /root): • cp /opt/glite/yaim/examples/gilda_ig-site-info.def /root/gilda_ig-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 gilda_ig-site-info.def 9th EELA Tutorial, Bogotá, 05-09 March 2007

  14. Local repository • We have installed a local repository at UNAM, so you have to specify its correct path in my-site-info.def: OS_REPOSITORY="rpm http://gaia.eela.ufrj.br/yam sl3-i386 os contrib updates" LCG_REPOSITORY="rpm http://mnto04.uniandes.edu.co/yam glite_sl3-i386 3_0 3_0_externals 3_0_updat es condor" IG_REPOSITORY="rpm http://grid018.ct.infn.it/yam ig_sl3-i386 3_0_0 utils" GILDA_REPOSITORY="rpm http://mnto04.uniandes.edu.co/yam gilda_sl3-i386 app 3_0_0" CA_REPOSITORY=" rpm http://grid018.ct.infn.it/yam glite_sl3-i386 security" 9th EELA Tutorial, Bogotá, 05-09 March 2007

  15. Middleware installation with YAIM • We are ready to install the services: • /opt/glite/bin/gilda_ig_install_node /root/gilda_ig-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/gilda_ig-site-info.def GILDA_ig_myServiceName 9th EELA Tutorial, Bogotá, 05-09 March 2007
