Software

/marksw

/marksw/ contains a large selection of pre-compiled software for use by the group. Each package is found in /marksw/$NAME/$VERSION/. The source code and details of how the software was built is in /marksw/$NAME/$VERSION/SOURCE. In the bash (csh) configuration file /marksw/BASHRC (/marksw/CSHRC), is a simple shell function, module, which can be used in the following ways:

1. module avail
2. module $NAME/$VERSION ...

The first use lists the possible $NAME/$VERSION options for the second use. The second use simply adds for each $NAME/$VERSION argument, /marksw/$NAME/$VERSION/bin and /marksw/$NAME/$VERSION/sbin to the beginning of the contents of the PATH environment variable; /marksw/$NAME/$VERSION/lib64 and /marksw/$NAME/$VERSION/lib to the beginning of the contents of the LD_LIBRARY_PATH environment variable; and /marksw/$NAME/$VERSION/man to the beginning of the contents of the MANPATH environment variable.

The module command is sourced in the global bash configuration file /etc/bashrc and in the global csh configuration file /etc/csh.local.

Install SystemImager Image Server (for Imaging Workstations)

The following relates to the once-off installation of systemimager for serving images. See CentosWorkstation for information as to the actual use of systemimager for getting the images onto the image server for serving.

• yum install perl-AppConfig
• rpm -iv systemconfigurator-2.2.11-1.noarch.rpm systemimager-common-4.1.6-1.noarch.rpm systemimager-server-4.1.6-1.noarch.rpm systemimager-x86_64initrd_template-4.1.6-1.noarch.rpm systemimager-x86_64boot-standard-4.1.6-1.noarch.rpm
• mkdir -p /systemimager/{images,overrides,tarballs,torrents}
• Edit /etc/systemimager/systemimager.conf:
  • DEFAULT_IMAGE_DIR = /systemimager/images
  • DEFAULT_OVERRIDE_DIR = /systemimager/overrides
  • AUTOINSTALL_TARBALL_DIR = /systemimager/tarballs
  • AUTOINSTALL_TORRENT_DIR = /systemimager/torrents
• Make sure firewall allows incoming connections to port 873/TCP (for serving images over rsync)
• We don't use the tftp server for network booting the workstations as we don't have access to the DHCP server for the MD VLAN, rather a boot CD is created (or systemimager is booted through Grub). See CentosWorkstation for details.
• Turn on image server for permanent operation:
  • chkconfig systemimager-server-rsyncd on
