2.2. On an Existing Server

The hpc Roll may also be added onto an existing server (or frontend). For sake of discussion, assume that you have an iso image of the roll called hpc.iso. The following procedure will install the Roll, and after the server reboots the Roll should be fully installed and configured.

$ su - root
# rocks add roll hpc.iso
# rocks enable roll hpc
# rocks-dist dist
# kroll hpc | bash
# init 6
