  1. gLite UI Installation Bouchra RAHIM(rahim@cnrst.ma) Joint EPIKH/EUMEDGRID-Support Event in Rabat Morocco, 30.05.2011

  2. gLite UI • The access point to the glite Grid is the User Interface • This can be any machine where users have an account and where their user certificate is installed • From a UI, a user can be authenticated and authorized to use the glite Grid resources • It provides CLI tools to perform some basic Grid operations: • list all the resources suitable to execute a given job; • submit jobs for execution; • cancel jobs; • retrieve the output of finished jobs; • show the status of submitted jobs; • retrieve the logging and bookkeeping information of jobs; • copy, replicate and delete files from the Grid; • retrieve the status of different resources from the Inforamtion System 2

  3. Preliminaries • The instructions provided in this presentation assume that you are going to use a machine with Scientific Linux 5.4 installed. • Virtual Machine image (GILDA VM Base_SLC5.4_x86_64) available at:https://gilda.ct.infn.it/VirtualServices.html 3

  4. Preliminaries Login as root@pcxx.magrid.ma XX = 01, 02, 03, ….., 28 Password: grid2011 Preliminaries

  5. System requirements • Check if exists the ntp service otherwise install that: yum install ntp • Check that public machine name is NOT an alias for “localhost”, but appears on a line by its own, like in the following: • Please check: • If you have a valid hostname • To verify, type: hostname -f • To edit the hostname: • Disable Selinux: make sure /etc/selinux/config contains line: • REBOOT your server, for changes to take effect • root# cat /etc/hosts 213.92.16.191 servername.some.domain.org servername 127.0.0.1 localhost.localdomainlocalhost • vim /etc/hostname • vim /etc/sysconfig/network • hostname <pc_name> • service network restart • SELINUX=disabled 5

  6. System requirements (2/2) • Disable automatic yum update: • chkconfig yum off ; service yum stop • Similarly disable other useless services (sendmail, pcmcia, isdn,...): see for example http://wiki.eumedgrid.eu/twiki/bin/view/InfrastructureStatus/SiteSecurityAndPerformance • Cleanup yum cache: • yum clean all • Download list of important packages from CIC portal, https://cic.gridops.org/index.php?section=vo&vo=eumed see section “Other requirements” and save to a file, then issue command: • cat <file.txt> | xargs -i yum -y install {} 6

  7. Repository settings • Specify the mrepo host: export MREPO=http://repo.magrid.ma/yumrepo/glite32 • Configure the repository as follows: REPOS="dag glite-GENERIC lcg-CA glite-UI" • Get repositories with: for name in $REPOS; do wget $MREPO/$name.repo -O /etc/yum.repos.d/$name.repo; done • Install CAs (this need to be done for ANY profile): yum install lcg-CA ca-policy-egi-core ca-policy-lcg 7

  8. YUM install • Glite UI Metapackage installation: yum groupinstall glite-UI • we use groupinstall command to install all the packages for the glite-UI group of packages, read from the comps.xml file on the repo server. • glite-UI: all the software needed to install and run a gLite User Interface, yaim-utilities for the configuration of the UI, libraries, and all the CLI tools to interact with the gLite Grid services. 8

  9. site-info.def • All the configuration samples files are located in /opt/glite/yaim/examples/siteinfo directory • it’s better to make a copy of the original files • Open your own site-info.def and customize it: mkdir/opt/glite/yaim/etc/siteinfo/ cp /opt/glite/yaim/examples/siteinfo/site-info.def /opt/glite/yaim/etc/siteinfo/site-info.def vi/opt/glite/yaim/etc/siteinfo/site-info.def 9

  10. EUMED Settings - Setup site-info.def https://twiki.cern.ch/twiki/bin/view/LCG/Site-info_configuration_variables#UI BDII_HOST=bdii.eumedgrid.eu (or your own if you have one) WMS_HOST=wms-01.eumedgrid.eu (or your own if you have one) LB_HOST=wms-01.eumedgrid.eu (or your own if you have one) PX_HOST=myproxy.ct.infn.it LFC_HOST=lfc.ulakbim.gov.tr (or your own if you have one) DPM_HOST=torik1.ulakbim.gov.tr (or your own if you have one) 10

  11. Add EUMED Settings VOS="eumed" Add eumed here VO_EUMED_SW_DIR=$VO_SW_DIR/eumed VO_EUMED_DEFAULT_SE=$SE_HOST VO_EUMED_STORAGE_DIR=$CLASSIC_STORAGE_DIR/eumed VO_EUMED_VOMS_SERVERS="'vomss://voms2.cnaf.infn.it:8443/voms/eumed?/eumed' 'vomss://voms-02.pd.infn.it:8443/voms/eumed?/eumed'" VO_EUMED_VOMSES="'eumed voms2.cnaf.infn.it 15016 /C=IT/O=INFN/OU=Host/L=CNAF/CN=voms2.cnaf.infn.it eumed' 'eumed voms-02.pd.infn.it 15016 /C=IT/O=INFN/OU=Host/L=Padova/CN=voms-02.pd.infn.it eumed'" VO_EUMED_VOMS_CA_DN="'/C=IT/O=INFN/CN=INFN CA' '/C=IT/O=INFN/CN=INFN CA'" VO_EUMED_WMS_HOSTS="wms-4.dir.garr.it wms.ulakbim.gov.tr wms-01.eumedgrid.eu wms.grid.arn.dz rb-eugrid.eri.sci.eg“ !Make sure to comment VO_<vo_name>... 11

  14. Configuring UI • Update the date (ftp://repo.magrid.ma/pub/GridSchoolConfFiles/) configure ntp : /etc/ntp.conf , /etc/ntp/step-tickers /etc/init.d/ntpd stop ntpdate ntp.marwan.ma /etc/init.d/ntpd start • Disableiptables • service iptables stop • Chkconfigiptables off • Configure the UI with YAIM (To check the syntax : source <path_to_siteinfo>/site-info.def ) /opt/glite/yaim/bin/yaim -c -s <path_to_siteinfo>/site-info.def -n glite-UI • If everything is ok, the UI is now READY for testingYAIM does not configure the LFC_HOST variable; please edit the file /opt/glite/etc/profile.d/grid-env.sh and add the following for eumed: gridenv_set "LFC_HOST" "lfc.ulakbim.gov.tr" 14

  15. Testing UI [root@pc01 ~]# adduser grid01 • [root@pc01 ~]# mkdir /home/grid01/.globus [root@pc01 ~]# cp /root/user_cert/usercert.pem /home/grid01/.globus/usercert.pem [root@pc01 ~]# cp /root/user_cert/userkey.pem /home/grid01/.globus/userkey.pem [root@pc01 ~]# chown grid01 /home/grid01/.globus/usercert.pem [root@pc01 ~]# chown grid01 /home/grid01/.globus/userkey.pem [root@pc01 ~]# chmod 400 /home/grid01/.globus/userkey.pem [root@pc01 ~]# su – grid01 [grid01@pc01 ~]$ voms-proxy-init --voms eumed Enter GRID pass phrase: [grid2011] Your identity: /C=MA/O=MaGrid/OU=CNRST/CN=Grid School Creating temporary proxy ................................................................. .......................................

  16. Testing UI for GILDA • OtherTests: Copy a jdl file: Password [grid01] Submit a job: lfc-ls /grid scp grid01@ui01.magrid.ma:/home/grid01/hostname.jdl . glite-wms-job-submit -a –o jobid hostname.jdl 16

  17. Testing UI for EUMED Installation • For the real installation you have to export you personal certificate from web browser to the UI and than have a look at the following: ATTENTION USE eumed INSTEAD gilda • Certificate management: https://grid.ct.infn.it/twiki/bin/view/GILDA/HowToConvertPkcs12ToPem • Voms creation with extentions https://grid.ct.infn.it/twiki/bin/view/GILDA/AuthenticationAuthorization#Creation_of_a_proxy_with_voms_ex • Job Submission https://grid.ct.infn.it/twiki/bin/view/GILDA/SimpleJobSubmission • Data Management https://grid.ct.infn.it/twiki/bin/view/GILDA/DataManagement 17
