    Installation tarballs can be downloaded from this page.
    • The OSCAR distribution comes in two OSCAR tarballs and a set of repository
      tarballs
      • oscar-base-5.0.tar.gz: the base OSCAR tarball stripped of almost every binary packages (rpms)
      • oscar-srpms-5.0.tar.gz: the SRPMS, you only need this if you want to rebuild rpms
      • oscar-repo-common-rpms-5.0.tar.gz: repository of noarch rpms used on all supported distributions
      • oscar-repo-DISTRO-VERSION-ARCH-5.0.tar.gz: repository of distro and architecture specific rpms.
    • Online documentation
      Is located at: http://svn.oscar.openclustergroup.org/wiki/oscar:5.0:install_guide The installation procedure of OSCAR 5 is quite different to that of previous versions. Please read the documentation!
    • OSCAR installation
      1. Download the oscar-base tarball. Unpack it in /opt. Rename the unpacked directory, if you want (e.g. /opt/oscar)
      2. In the unpacked directory execute as root the command: 
        env OSCAR_HOME=`pwd` scripts/distro-query
        Remember the paths printed in the first two lines under "Distro repository".
      3. Copy all RPMs of the master node's distribution into the directory /tftpboot/distro/DISTRO-VERSION-ARCH or /tftpboot/rpm. Check the table at the beginning of this page for the correct DISTRO-VERSION-ARCH combination for your distribution!
      4. Download the oscar-repo-common-rpms and the oscar-repo-DISTRO-VER-ARCH tarballls suitable for the distribution(s). Unpack them in the directory /tftpboot/oscar/.
      5. In the unpacked directory (e.g. /opt/oscar) execute: 
        ./install_cluster ETH_INTERFACE
        (ETH_INTERFACE is the cluster internal interface on the head node, e.g. eth0).
    • Repositories
      Instead of copying RPMs locally to the master node you can use online repositories: http://svn.oscar.openclustergroup.org/wiki/oscar:5.0:install_guide:ch3.5_advanced_repo
