  1. Software installation and setup Viet Tran Institute of Informatics Slovakia

  2. Overview • Creating new user account • Installing Java and Ant • Installing Globus Toolkit 4 • Setting up environment variable • Setting up security configurations • Deploying services Medigrid meeting Bratislava March 10-11

  3. Requirements • PC with Windows XP or Linux • Static IP addresses, should be registered to DNS • Memory, speed Medigrid meeting Bratislava March 10-11

  4. Creating a new user account • At the moment, we are installing GT4 in user home directory to avoid possible conflicts with other grid software • Do not use your working account, but create a new user (e.g. “globus”) for the installation Medigrid meeting Bratislava March 10-11

  5. Installing Java • Download Java SDK 1.4.2 from http://java.sun.com • WSRF work with Java 1.5, but not sure all other components will work • Use SDK, not JRE because you may need to compile some java code • Just unpacking the installation package to a directory (e.g. /home/globus/java or c:\globus\java) Medigrid meeting Bratislava March 10-11

  6. Installing Ant • Download Ant from http://jakarta.apache.org and unpack it to a directory (e.g. /home/globus/ant or c:\globus\ant) Medigrid meeting Bratislava March 10-11

  7. Installing Globus Toolkit 4 • We can provide binary package of Globus installation because the installer does not work in Windows XP • The Java core binary distribution of Globus miss some important components (MDS, CAS, OGSA-DAI) • Linux users can try to use the original installer • Just download the binary package of GT4 from us and unpack it in a directory (e.g. /home/globus/gt4 or c:\globus\gt4) Medigrid meeting Bratislava March 10-11

  8. Setting environment variable • These variables JAVA_HOME, ANT_HOME, GLOBUS_LOCATION must be set • In Linux with Bash • Add to /home/globus/.bashrc these lines export JAVA_HOME=/home/globus/java export ANT_HOME=/home/globus/ant export GLOBUS_LOCATION=/home/globus/gt4 • In Windows XP Go to Control Panel -> System -> Advanced -> Environments and add the variable • For convenient, user can add bin directories into PATH environment Medigrid meeting Bratislava March 10-11

  9. Setting trusted CAs • Download CA signing polices files and stored it in ~/.globus/certificates directory (i.e. /home/globus/.globus/certificates for Linux or C:\Documents and Settings\globus\.globus\certificates) Medigrid meeting Bratislava March 10-11

  10. Setting security configuration • Request host certificates for the services from CA and store them in files (e.g. /home/globus/.globus/hostcert.pem and /home/globus/.globus/hostcert.pem ) • Edit etc/globus_wsrf_core/server_config.wsdd and global_security_descriptor.xml for provide access to the certificates Medigrid meeting Bratislava March 10-11

  11. Deploying application services • Receive GAR files from service developers and deploy them into Globus (by simple ant command) Medigrid meeting Bratislava March 10-11

  12. Starting the container • Execute GLOBUS_LOCATION/bin/globus-start-container If everything is OK, you can start to use the web services Medigrid meeting Bratislava March 10-11

  13. Setting up MDS • There are several configuration files that must be modified • Leave that setting later, until you have your services working correctly Medigrid meeting Bratislava March 10-11
