WMS+LB Server Installation and Configuration Carlos Fuentes Bermejo IRIS-CERT/RedIRIS 11th EELA Tutorial, Madrid de Septiembre de 2007

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

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 root root887 Jun 14 12:28 hostkey.pem WMS+LB services requires a wide range of ports  (Set the firewall allowing input for any protocol in the range of ports > 1023  )

Glite and Gilda Metapackages Usual combination: RB and BDII Possible combination: CE and WMS CE/RB or RB/SE doesn’t work. Metapackag e Node typeDescription lcg-RBRBLCG Resource Broker glite-WMSLBWMSLBWMS + LB node GILDA_ig_R B Gilda LCG RB GILDA_ig_W MSLB Gilda WMS + LB

Gilda RB Installation Modify my-site-info.def and edit this fields:  RB_HOST=grid-XXX Install all packages for a Gilda LCG RB  /opt/glite/bin/gilda_ig_install_node./my-site-info.def GILDA_ig_RB Configure Gilda RB node  /opt/glite/bin/gilda_ig_configure_node./my-site- info.def GILDA_ig_RB

Testing the WMS Login to a user interface (sevillaXX in glite-tutor.ct.infn.it):  Create and Edit rb-test.conf with the following line (replace XXX to match your WMS+LB host):  [  VirtualOrganisation = "gilda";  NSAddresses = {  “gridXX.cica.es:7772”  };  LBAddresses = {  {“gridXX.cica.es:9000"}  };  MyProxyServer = "grid001.ct.infn.it";  ] Try:  Send a job and Monitor the run of your job and if you will be able to retrieve its output, if your are in the right way!

Testing the WMS (II) $ edg-job-submit --config-vo rb-test.conf hostname.jdl  Selected Virtual Organisation name (from --config-vo option): gilda  Connecting to host grid24.cica.es, port 7772  Logging to host glite-rb.ct.infn.it, port 9002  ***********************************************************  JOB SUBMIT OUTCOME  The job has been successfully submitted to the Network Server.  Use edg-job-status command to check job current status. Your job identifier (edg_jobId) is:  - ****************************************************** ****

Testing the WMS (III) $ edg-job-status 0TPYMsyKXKzN8f-QGD8g  ***********************************************  BOOKKEEPING INFORMATION:  Status info for the Job :  Current Status: Scheduled  Status Reason: Job successfully submitted to Globus  Destination: grid011f.cnaf.infn.it:2119/jobmanager-lcgpbs-short  reached on: Thu May 10 11:08:  ************************************************* $ edg-job-status 0TPYMsyKXKzN8f-QGD8ghttps://grid24.cica.es:9000/s- 0TPYMsyKXKzN8f-QGD8g  *************************************************  BOOKKEEPING INFORMATION:  Status info for the Job :  Current Status: Done (Success)  Exit code: 0  Status Reason: Job terminated successfully  Destination: grid011f.cnaf.infn.it:2119/jobmanager-lcgpbs-short  reached on: Thu May 10 11:12:  ***********************************************

Testing the WMS (IV) $ edg-job-get-output 0TPYMsyKXKzN8f-QGD8ghttps://grid24.cica.es:9000/s- 0TPYMsyKXKzN8f-QGD8g  **********************************************  JOB GET OUTPUT OUTCOME  Output sandbox files for the job:  -  have been successfully retrieved and stored in the directory:  /tmp/jobOutput/madrid12_s-0TPYMsyKXKzN8f-QGD8g  ********************************************** $ cd /tmp/jobOutput/grid24_s-0TPYMsyKXKzN8f-QGD8g $ ls  hostname.err hostname.out $ cat hostname.err $ cat hostname.out  egee013.cnaf.infn.it

WMS Logs Logs can be found in  /var/edgwl/networkserver/log/events.log  /var/edgwl/networkserver/log/workload_manager/ev ents.log They are the best starting point to deal with eventual problems. You can monitor and follow the jobs See if the BDII and RGMA purchasing is working fine
