11. Final tasks

11.1. Install compute node with cobbler

• Create your own kickstart template /var/lib/cobbler/kickstarts/compute.ks for compute nodes based on /var/lib/cobbler/kickstarts/sample_end.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 mhpc2024.

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.
