Installation Summary

This is a quick, high-level summary of the LosF installation process.

• Storage Preparation - LosF is intended to run from a shared directory between all nodes. This usually means a shared filesystem.

• SELinux Configuration - Currently recommended to be disabled, however in the future this will be addressed.

• Iptables Configuration - Basically, let your nodes get to the master node. Although technically there is no traffic required for LosF other than the local shared directory that LosF is shared on.

• Cobbler Installation - LosF both heavily relies on Cobbler and becomes a wrapper-script for replacing common Cobbler tasks.

• LosF Installation - Far easier than installing Cobbler.

• Kickstart Customization - There is a kickstart Cobbler snippet that needs to be modified and linked. This installs LosF (by mounting the LosF directory) and runs LosF for the first time during installation.

• Version Control - A relevant discussion on using version control and LosF.

• IPMI Considerations - LosF can manage nodes using handy IPMI scripts. There are automated ways to configure IPMI that are included here.

• PXE over Infiniband - Some meta-discussion on using PXE without an Ethernet connection to nodes.

• DNS Zone Authority - Some meta-discussion on linking the local-cluster DNS with the public DNS of an organization.

• SLURM Installation - Installation of a resource scheduler.
