  1. R-GMA Server Installation Claudio Cherubino INFN – Catania Third EELA Tutorial for Managers and Users Rio de Janeiro, 26-30 June 2006

  2. Outline • Introduction to R-GMA • How to install it • R-GMA configuration • Testing Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  3. Introduction to R-GMA • Relational Grid Monitoring Architecture (R-GMA) • Provides Information (which resources are available on the Grid) and Monitoring Services • Developed as part of the EuropeanDataGrid Project (EDG) • Now as part of the EGEE project. • Implementation of the Grid Monitoring Architecture (GMA) from the Global Grid Forum (GGF). • Uses a relational data model. • Data are viewed as tables. • Data structure defined by the columns. • Each entry is a row (tuple). • Queried using Structured Query Language (SQL). Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  4. Relational GMA Schema Registry Store Location Look up Location Producer Consumer Execute or Stream data • The data model is relational. • The table definition is globally unique and is stored in the Schema. • The Registry stores the Producers table name as well as the URL. • The data is inserted in the form of a tuple. • The Consumer gets the tuple from Producers. • Producers • publish: SQL “INSERT” • Consumers • collect: SQL “SELECT” Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  5. Installing R-GMA Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  6. Installation 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 (https://gilda.ct.infn.it/RPMS/) • edg_VO_Gilda rpm (https://gilda.ct.infn.it/RPMS/) • 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 Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  7. Installing R-GMA Server via apt 1. Create the file glite.list in the /etc/apt/sources.list.ddirectory and put these rows into it: rpm http://gaia.eela.if.ufrj.br/yam sl305-i386 os updates contrib rpm http://gaia.eela.if.ufrj.br/yam gilda_sl3-i386 app 3_0_0 rpm http://gaia.eela.if.ufrj.br/yam ig_sl3-i386 3_0_0 utils rpm http://gaia.eela.if.ufrj.br/yam glite_sl3-i386 security rpm http://gaia.eela.if.ufrj.br/yam glite_sl3-i386 3_0 3_0_externals 3_0_updates rpm http://gaia.eela.if.ufrj.br/yam sl305-i386 os updates contrib 2. Digit the following commands: > apt-get update > apt-get dist-upgrade 3. Install R-GMA: > apt-get install glite-rgma-server-config See also http://glite.web.cern.ch/glite/packages/R3.0/R20060502/APT.asp Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  8. R-GMA Server configuration • Copy the configuration template files from • $GLITE_LOCATION/etc/config/templates • To • $GLITE_LOCATION/etc/config • P.S: You can delete the glite-rgma-servicetool-serviceName.cfg.xml template file because it will not be used. • Now we will start to customize the just copied configuration files by replacing the “changeme” value in all user-defined parameters with the proper value. Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006

  9. R-GMA Server configuration • List of XML files to customize: • glite-global.cfg.xml • glite-rgma-common.cfg.xml • glite-rgma-server.cfg.xml • glite-rgma-servicetool.cfg.xml • glite-security-utils.cfg.xml Third EELA Tutorial, Rio de Janeiro, 26-30 June 2006
