  1. Hands-On Session:Operating System Installation and Configuration Regional SEE-GRID-SCI Training for Site Administrators Institute of Physics Belgrade March 5-6, 2009 Vladimir Slavnic Institute of Physics, Belgrade Serbia slavnic@scl.rs The SEE-GRID-SCI initiative is co-funded by the European Commission under the FP7 Research Infrastructures contract no. 211338

  2. OS Scientific linux 4.7 (Beryllium)‏ Fermi National Accelerator Laboratory and the European Organization for Nuclear Research (CERN) Compatible with and based on Red Hat Enterprise Linux‏

  3. Installation methods • Manual (interactive)‏ • Via kickstart • Installation sources • CD-Rom • Hard disk • NFS • FTP • HTTP

  4. Installation steps 1/3 • TCP/IP configuration • (DHCP or static address)‏ • Installation type • custom • Manual disk partitioning - usually create: • /boot • / • swap

  5. Installation steps 2/3 • Boot loader – grub is our choice • usually no password and installed in MBR • Network configuration • Hostname configuration • Firewall • SELinux

  6. Installation steps 3/3 • Language Support • Time Zone • Root password • Package selection

  7. Configuration 1/7 • Set default init level - 3 • Set NTP • ntp.conf • ntp.drift • ntp.drift.TEMP scp demo:ntp.conf /etc touch /etc/ntp.drift touch /etc/ntp.drift.TEMP chown ntp:ntp /etc/ntp.drift* chkconfig ntpd on /etc/init.d/ntpd start

  8. Configuration 2/7 • Remove existing java packages rpm –qa | grep java rpm –e <packages> • Add scl repos • Disable sl repos • Get scl repos: wget http://rpm.scl.rs/yum.conf/scl-jpackage.repo wget http://rpm.scl.rs/yum.conf/scl.repo wget -N -nd -r -l1 -Ascl-sl* http://rpm.scl.rs/yum.conf/ (or one by one: wget http://rpm.scl.rs/yum.conf/scl-sl.repo)‏ yum update

  9. Configuration 3/7 • Disable yum nightly update chkconfig yum off • Install java yum install java-1.5.0-sun-devel • Install and configure scl-scripts yum install scl-scripts config files in /opt/scl/etc/

  10. Configuration 4/7 • Create SSH keys for exchange ssh-keygen -t rsa -N "" -q -f /root/.ssh/id_rsa; ssh-keygen -t dsa -N "" -q -f /root/.ssh/id_dsa • Copy public keys (.pub) to authorized_keys file cat /root/.ssh/*.pub

  11. Configuration 5/7 • Get scl-lcg-ca.repo wget http://rpm.scl.rs/yum.conf/scl-lcg-ca.repo • Install lcg-CA yum install lcg-CA

  12. Configuration 6/7 • Get specific node gLite repos WN example: wget http://rpm.scl.rs/yum.conf/scl-glite-WN.repo wget http://rpm.scl.rs/yum.conf/scl-glite-TORQUE_client.repo • Install packages yum install torque-2.3.6-1cri.slc4 yum install torque-mom-2.3.6-1cri.slc4.i386.i386 yum install glite-WN yum install glite-TORQUE_client yum install mpiexec yum install lcg-CA

  13. Configuration 7/7 • Get host certificates if needed and copy them to • /etc/grid-security/ • Get configuration files (site-info.def and others)‏ • Configure node with YAIM • Add NFS exports on specific nodes • Ready to go!

  14. Thank you!
