11. Final tasks

11.1. Install compute node with cobbler

Warning

Due to a bug in Cobbler, the snippet redhat_register need to be removed from the kicktart file. In the sample.ks file, this snippet is located in the line 66.

  • Create your own kickstart template /var/lib/cobbler/templates/compute.ks for compute nodes based on /var/lib/cobbler/templates/sample.ks. Keep cobbler specific additions intact.

  • Create a profile which uses this template and assign two of your systems to it

  • Your kickstart should install a minimal set of RPM packages

  • Install at least one good editor (vim or emacs)

  • You should be able to SSH into the node after installation

11.2. Change default password

  • Change the default root password for newly installed systems to mhpc2025.

11.3. Add a custom login message

  • Create a snippet which creates a custom login message by creating the /etc/motd text file.

    Example Login message
    cat > /etc/motd <<EOF
 __  __ _   _ ____   ____
|  \/  | | | |  _ \ / ___|
| |\/| | |_| | |_) | |
| |  | |  _  |  __/| |___
|_|  |_|_| |_|_|    \____|

EOF

  • Modify your kickstart template(s) to use the snippet.
