  1. BDII Server Installation Yubiryn Ramírez G. ULA – Venezuela. Ninth EELA Tutorial Users and System Administrators. Bogotá, 09.03.2007.

  2. This presentation is based on LCG and gLite manuals and previous EELA tutorials Bogotá, Ninth EELA Tutorial, 09.03.2007

  3. Outline • Information System Overview • How to install a BDII Server • BDII customization and references Bogotá, Ninth EELA Tutorial, 09.03.2007

  4. Information System Overview • The Information System (IS) provides information about grid´s resources and their actual status. Bogotá, Ninth EELA Tutorial, 09.03.2007

  5. Information System Levels • Resource level: Grid Resource Information Server (GRIS) • One GRIS on top of each CE, SE, RB, MyProxy (no WNs). • Sensors and scripts get status of concrete resources statically (e.g. GlueCEUniqueID) or dynamically (e.g. GlueCEStateWaitingJobs) • Site level: Grid Index Information Server (GIIS) • Compiles all the information of the different GRISs in a site. • LCG-2 recommends using a BDII instead of a GIIS • Improves robustness and stability. • Called the site BDII. • Top level: Berkeley DB Information Index (BDII) • Keeps all Grid information about the VOs (generally only one). • Stores information from local BDIIs or GIISs in its database. • Only queries sites that are included in a configuration file. Bogotá, Ninth EELA Tutorial, 09.03.2007

  6. BDII • Users and other Grid services (such as the RB) can query BDIIs to get information about the Grid status. • Each BDII collects information from the site GIISes (or local BDII) defined in a configuration file, which is accessed through a web interfaces. • Every two minutes a cron-job runs a script and collects information (pull model) from all the GIISes (local BDII) listed in the configuration file. Bogotá, Ninth EELA Tutorial, 09.03.2007

  7. BDII Abbreviations: BDII: Berkeley DataBase Information Index GIIS: Grid Index Information Server GRIS: Grid Resource Information Server Each site can run a BDII. It collects the information coming from the BDIIs/GIISs At each site, a site GIIS collects the information given by the GRISs Local GRISs run on CE, SE, RB, MyProxy at each site and report dynamic and static information From LCG2.3.0 site GIIS has been replaced by “site” BDII Bogotá, Ninth EELA Tutorial, 09.03.2007

  9. Installing BDII Server Bogotá, Ninth EELA Tutorial, 09.03.2007

  10. Pre-requisites • Start from the base machine you installed in the INTRODUCTORY tutorial • Verify that these packages are installed and properly configured: • Java SDK • Ntp daemon • CA_Gilda rpm • edg_VO_Gilda rpm • glite-yaim-3.0.0-11 • gilda_ig-yaim-3.0.0-37 • Also check that your host certificates are present in /etc/grid-security and have proper permissions: -rw-r--r-- 1 root root 1127 Jun 14 12:27 hostcert.pem -r-------- 1 root root 887 Jun 14 12:28 hostkey.pem Bogotá, Ninth EELA Tutorial, 09.03.2007

  11. Glite and Gilda Metapackages • Usual combinación: RB and BDII • CE and BDII: doesn´t work Bogotá, Ninth EELA Tutorial, 09.03.2007

  12. site-info.def • BDII_FCR: URL of the Freedom of Choice for Resources. (Web interface that provides a facility for VOs to modify resources list available for them on a BDII level, based on their own decision or Sites Functional Test (SFT) results) • BDII_HOST:BDII Hostname. • BDII_HTTP_URL:List of the GIIS (or site BDII) from which the BDII server fetches the information • BDII_REGIONS:List of nodes publishing information on the BDII. BDII_REGIONS="CE SE RB LFC VOBOX PX FTS MON“ BDII_CE_URL="ldap://$CE_HOST:2135/mds-vo-name=local,o=grid" BDII_SE_URL="ldap://$CLASSIC_HOST:2135/mds-vo-name=local,o=grid" … … BDII_FTS_URL="ldap://$FTS_HOST:2170/mds-vo-name=resource,o=grid" BDII_MON_URL="ldap://$MON_HOST:2135/mds-vo-name=local,o=grid" Bogotá, Ninth EELA Tutorial, 09.03.2007

  13. site-info.def Copy http://mnto04.uniandes.edu.co/Base/gilda_ig-site-info.def into /root/my-site-info.def and edit these fields: BDII_HOST=eventogridXX.uniandes.edu.co Bogotá, Ninth EELA Tutorial, 09.03.2007

  14. Installation and Configuration • Install the BDII server: /opt/glite/bin/gilda_ig_install_node /root/my-site-info.def GILDA_ig_BDII • Configure the BDII server: /opt/glite/bin/gilda_ig_configure_node /root/my-site-info.def GILDA_ig_BDII Bogotá, Ninth EELA Tutorial, 09.03.2007

  15. Firewall configuration Be sure that your firewall is open for bdii listening port 2170: In /etc/sysconfig/iptables add: -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 2170 -j ACCEPT service iptables restart Bogotá, Ninth EELA Tutorial, 09.03.2007

  16. BDII Server Testing & Customization Bogotá, Ninth EELA Tutorial, 09.03.2007

  17. BDII testing • Issue an ldapsearch to check if BDII is correctly publishing sites informations: ldapsearch -x -h <hostname> -p 2170 -b 'mds-vo-name=local,o=grid‘ • Log into a LCG User Interface machine and use lcg-infosites: export LCG_GFAL_INFOSYS=<hostname>:2170 lcg-infosites --vo gilda ce Bogotá, Ninth EELA Tutorial, 09.03.2007

  18. BDII customization • BDII configuration file can be found in /opt/bdii/etc/bdii.conf Bogotá, Ninth EELA Tutorial, 09.03.2007

  19. BDII customization BDII_PORT_READ=2170 BDII_PORTS_WRITE="2171 2172 2173" BDII_USER=edguser BDII_BIND=mds-vo-name=local,o=grid BDII_PASSWD=26082 BDII_SEARCH_FILTER='(|(objectClass=GlueSchemaVersion)(objectClass=GlueTop))' BDII_SEARCH_TIMEOUT=30 BDII_BREATHE_TIME=60every 2 minute BDII cache is refreshed BDII_AUTO_UPDATE=yesthe list of GIIS is dynamic (no=static) BDII_AUTO_MODIFY=no BDII_DIR=/opt/bdii/ BDII_UPDATE_URL=http://grid018.ct.infn.it/fileadmin/bdii/glite-bdii-update.conf BDII_UPDATE_LDIF=http:// SLAPD=/usr/sbin/slapd SLAPADD=/usr/sbin/slapadd Bogotá, Ninth EELA Tutorial, 09.03.2007

  20. BDII customization BDII log files in /opt/bdii/var/bdii.log Bogotá, Ninth EELA Tutorial, 09.03.2007

  21. BDII customization (II) • Example: • Change BDII_UPDATE_URL to: http://grid-deployment.web.cern.ch/grid-deployment/gis/lcg2-bdii/dteam/lcg2-all-sites.conf • Restart the service with: /etc/init.d/bdii restart • Give a look to the new information published by the service Bogotá, Ninth EELA Tutorial, 09.03.2007

  22. BDII customization (III) The file /opt/bdii/etc/bdii-update.conf contains the list of GIIS: ... INFN-CATANIA ldap://grid010.ct.infn.it:2170/mds-vo-name=infn-catania,o=grid # 2.6.0 INFN-CNAF ldap://grid011f.cnaf.infn.it:2170/mds-vo-name=infn-cnaf,o=grid # 2.6.0 INFN-PADOVA ldap://gilda-ce-01.pd.infn.it:2170/mds-vo-name=infn-padova,o=grid # 2.6.0 IISAS-BRATISLAVA ldap://dgt01.ui.savba.sk:2170/mds-vo-name=iisas-gilda,o=grid # 2.6.0 ULA-MERIDA ldap://grid006.cecalc.ula.ve:2170/mds-vo-name=ula-merida,o=grid Bogotá, Ninth EELA Tutorial, 09.03.2007
