  1. BDII Server Installation and Configuration Manuel Rubio del Solar Extremadura Advanced Research Center (CETA-CIEMAT) 11th EELA Tutorial for Users Sevilla, 10-14th September 2007

  2. This presentation is based on LCG and gLite manuals and previous EELA tutorials

  3. Outline • Information System Overview • How to install a BDII Server • BDII customization and references

  4. Information System Overview

  5. LCG 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.

  6. LCG Information System Hierarchy 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 Abbreviations: BDII: Berkeley DataBase Information Index GIIS: Grid Index Information Server GRIS: Grid Resource Information Server From LCG2.3.0 site GIIS has been replaced by “site” BDII

  8. Installing BDII Server

  9. Installation Pre-requisites • Always verify the deployment of • Java SDK • NTP daemon • APT • Latest glite-yaim • Check your host certificates in /etc/grid-security and its permissions: • -rw-r--r-- 1 root root1127Jun 14 12:27 hostcert.pem • -r-------- 1 root root887 Jun 14 12:28 hostkey.pem • Firewall must be opened for BDII listening port (2170). • On /etc/sysconfig/iptables add • -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 2170 -j ACCEPT • And execute • service iptables restart

  10. Glite and Glida Metapackages • Usual combination: RB and BDII • CE and BDII doesn’t work.

  11. site-info.def Fields • 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"

  12. Generic BDII Installation • Edit /opt/glite/yaim/examples/site-info.def and use it in all the nodes. • Install the metapackage for a BDII • /opt/glite/yaim/scripts/install_node ./my-site-info.def glite-BDII • Configure as BDII node • /opt/glite/yaim/scripts/configure_node ./my-site-info.def BDII

  13. Gilda BDII Installation (I) • Create a directory called BDII in the root directory. (mkdir /root/BDII) • Copy /opt/glite/yaim/examples/siteinfo/site-info.def to the recently created directory. • Rename the copied file to my-site-info.def

  14. Gilda BDII Installation (II) • Modify my-site-info.def and edit this fields: BDII_HOST=(YOUR HOSTNAME) BDII_HTTP_URL=“http://grid018.ct.infn.it/fileadmin/bdii/gilda-bdii-update.conf” • Install all packages for a Gilda BDII • /opt/glite/bin/gilda_ig_install_node /root/BDII/my-site-info.def GILDA_ig_BDII • Configure Gilda BDII • /opt/glite/bin/gilda_ig_configure_node /root/BDII/my-site-info.def GILDA_ig_BDII

  15. BDII Server Testing & Customization

  16. Test Your New BDII Server • Issue an ldapsearch to check if BDII is correctly publishing the information: • ldapsearch -x -h grid-XXX -p 2170 -b mds-vo-name=local,o=grid • Logged into a User Interface machine use lcg-infosites: • export LCG_GFAL_INFOSYS=grid-XXX • lcg-infosites --vo gilda se

  17. BDII customization • BDII log files in /opt/bdii/var/bdii.log • BDII configuration files in /opt/bdii/etc • bdii.conf: BDII_PORT_READ=2170 BDII_PORTS_WRITE="2171 2172 2173" BDII_USER=edguser BDII_BIND=mds-vo-name=local,o=grid BDII_PASSWD=23385 BDII_SEARCH_FILTER='(|(objectClass=GlueSchemaVersion)(objectClass=GlueTop))' BDII_SEARCH_TIMEOUT=30 BDII_BREATHE_TIME=60 -- every 2 minutes BDII cache is refreshed BDII_AUTO_UPDATE=yes - set to no if you want to create a static list of GIIS BDII_AUTO_MODIFY=yes BDII_DIR=/opt/bdii/ BDII_UPDATE_URL=http://grid018.ct.infn.it/fileadmin/bdii/gilda-bdii-update.conf BDII_UPDATE_LDIF=http://goc.grid-support.ac.uk/gridsite/bdii/BDII/www/bdii-update.ldif SLAPD=/usr/sbin/slapd SLAPADD=/usr/sbin/slapadd

  18. BDII Customization • 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 • /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 …
