  1. SRM + gLite IO Server install Emidio Giorgio INFN Catania First EELA Grid Tutorial for user and system administrators Madrid, 21.02.2006

  2. SRM + gLite IO server • IO server is the gLite component in charge of handling user input-output request • gLite IO server relies against a Mass Storage System implementing SRM interface • gLite IO server comunicates with MSS through SRM • Tested MSS are CASTOR, dCache and DPM • So to use gLite IO you need an SRM too ! • Further details on DPM • https://uimon.cern.ch/twiki/bin/view/LCG/DpmAdminGuide First EELA Grid Tutorial for user and system administrators

  3. Dpm installation First EELA Grid Tutorial for user and system administrators

  4. Installing DPM via apt • Verify if apt is present: • rpm -qa | grep apt • Install apt if necessary: • rpm -ivh http://linuxsoft.cern.ch/cern/slc30X/i386/SL/RPMS/apt-0.5.15cnc6-8.SL.cern.i386.rpm • Add gLite apt repository: • Put one of the following lines in a file (e.g. glite.list) inside the /etc/apt/sources.list.d directory • rpm http://glitesoft.cern.ch/EGEE/gLite/APT/R1.5/ rhel30 externals Release1.5 updates • Update apt repository: • apt-get update • apt-get dist-upgrade • Install DPM server: • apt-get install glite-dpm-disk-server-config • apt-get install glite-dpm-server-mysql-config Extra packages needed (non freely distributable) : • J2SE v 1.4.2_08 JRE: http://java.sun.com/j2se/1.4.2/download.html See http://glite.web.cern.ch/glite/packages/APT.asp First EELA Grid Tutorial for user and system administrators

  5. Preliminary • Request host certificates for the box • https://gilda.ct.infn.it/CA/mgt/restricted/srvreq.php • Copy host certificate (hostcert.pem and hostkey.pem) in /etc/grid-certificates. • chmod 644 hostcert.pem • chmod 400 hostkey.pem • If planning to use certificates released by unsupported EGEE CA’s, be sure that their public key and CRLs (usually distributed with an rpm) are installed. • CA GILDA ones are available from https://gilda.ct.infn.it/RPMS/ca_GILDA-0.28.1.i386.rpm First EELA Grid Tutorial for user and system administrators

  6. gLite configuration – short reminder • Configuration files • XML format • templates provided in /opt/glite/etc/config/templates • Hierarchy of configuration file • Global configuration file • service specific configuration files • Parameter groups • User parameters (‘changeme’) • Advanced parameters • System parameters First EELA Grid Tutorial for user and system administrators

  7. 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 • Xml files are provided as templates, under /opt/glite/etc/config/templates • Copy templates file to /opt/glite/etc/config glite-dpm-server.cfg.xml glite-rgma-gin.cfg.xml glite-global.cfg.xml glite-rgma-servicetool.cfg.xml glite-dpm-disk-server.cfg.xml glite-rgma-common.cfg.xml glite-security-utils.cfg.xml vo-list.cfg.xml First EELA Grid Tutorial for user and system administrators

  8. Other cfg.xml • vo-list.cfg.xml • Fill with the information on the VO (VOMS) that the services will support. • glite-rgma-common.cfg.xml • Set the RGMA-server name(s) • glite-rgma-servicetool.cfg.xml • Just the machine FQDN name on rgma.servicetool.sitename attribute • glite-global.cfg.xml • General aspects. Typically just the JAVA_HOME attribute needs to be changed, put in the location of your JVM • glite-rgma-gin.cfg.xml • “NO” for both the attributes • glite-security-utils.cfg.xml • Just set the cron.mailto attribute value First EELA Grid Tutorial for user and system administrators

  9. glite-dpm-disk-server.cfg.xml • Provides configuration for the DPM clients (gsiftp, rfio) • An instance of dpm-disk-server must be running on each machine exporting disk space • Preliminary • Each “piece” of fs we want to export must stay on a separate partition, owned by the user running DPM client services • So create a separate partition on filesystem • See command history for details Key values : dpm-server.host : set to the DPM server FQDN (itself in this configuration) dpns-server.host : set to the DPNS server FQDN (itself in this configuration) Now we need to configure the DPM server……. First EELA Grid Tutorial for user and system administrators

  10. glite-dpm-server.cfg.xml • Key values • db.typemysql (don’t set root password and be sure that mysql server hasn’t…) • disk-server.list : fill with list of disk server which are exporting filesystems (the box itself in this case) • io-server.voname : name of vo in the IO server this DPM will support • io-server.hostname : put the name of the machine which will run the IO server relying on this DPM (the box itself in this case) • io-server.certificate.subject :the subject of IO server host certificate First EELA Grid Tutorial for user and system administrators

  11. Commit configuration • Once edited xml files, commit configuration for both disk-server and DPM server • cd/opt/glite/etc/config/scripts • ./glite-dpm-disk-server-config.py –-configure • ./glite-dpm-server-config.py –-configure • ./glite-dpm-server-config.py –-start • ./glite-dpm-disk-server-config.py –start First EELA Grid Tutorial for user and system administrators

  12. Post configuration • DPM server and disk-server are now running, but they are not exporting any part of filesystem • We have to build the DPNS namespace, with the right permissions • dpns-mkdir • dpns-chmod • dpns-chown • dpns-setacl • We should make aware DPM clients of which disk space they have to export • dpm-addfs • dpm-addpool • The disk portion we’ll export should stay on a separate partition owned by the user running dpm (dpmmgr usually) • See related history for deep details !

  13. IO server Installation First EELA Grid Tutorial for user and system administrators

  14. Installing gLite IO server via apt • Verify if apt is present: • rpm -qa | grep apt • Install apt if necessary: • rpm -ivh http://linuxsoft.cern.ch/cern/slc30X/i386/SL/RPMS/apt-0.5.15cnc6-8.SL.cern.i386.rpm • Add gLite apt repository: • Put one of the following lines in a file (e.g. glite.list) inside the /etc/apt/sources.list.d directory • rpm http://glitesoft.cern.ch/EGEE/gLite/APT/R1.4/ rhel30 externals Release1.4 updates • Update apt repository: • apt-get update • apt-get dist-upgrade • Install DPM server: • apt-get install glite-io-server-config Extra packages needed (non freely distributable) : • J2SE v 1.4.2_08 JRE: http://java.sun.com/j2se/1.4.2/download.html See http://glite.web.cern.ch/glite/packages/APT.asp First EELA Grid Tutorial for user and system administrators

  18. glite-io-server.cfg.xml • VO instance section(s) : for each VO served, need to configure an instance • init.CatalogType (fireman) • io-resolve-common.SeHostname (the name of SRM box) • io-resolve-common.SrmEndPoint SRM endpoint • io-resolve-common.RootPath DPNS namespace for the VO • io-resolve-common.SeProtocol rfio • io-authz-fas.FasEndpoint endpoint of Fireman catalogue • io-resolve-fireman.FiremanEndpoint = FasEndpoint • io-daemon.Port (< 9999) • General section : service parameter (uid, gid) • init.username init.groupname uid—gid First EELA Grid Tutorial for user and system administrators

  19. Post configuration • Before committing configuration, is better to check the gridmap file is filled • Put on /opt/glite/etc/glite-mkgridmap.conf aline for each served VO • The vo users will be mapped so to the user running IO daemons /opt/glite/etc/config/scripts/mkgridmap.py ./glite-io-server-config.py --configure ./glite-io-server-config.py --start • Enjoy ! group vomss://voms.ct.infn.it:8443/voms/gilda?/gilda gliteio First EELA Grid Tutorial for user and system administrators
