Frontend Central Server

1.7. Frontend Central Server

A Central Server is a Rocks Frontend node that can kickstart other frontends and provide rolls over the network, in a process called WAN kickstart. All Rocks frontends have the ability to act as central servers.

From Rocks 3.3.0 onwards, the standard distribution in /home/install/rocks-dist contains a distro suitable for WAN kickstart. The only steps you must take is to open WWW access on your frontend for the purpose of RPM package transfer. See Enable WWW access.


Ensure that the hostname on central is fully qualified. Specifically, the "PublicHostname" value in the app_globals table of the database must be correct and reachable from the outside world.

1.7.1. Adding Rolls to serve on a Central

You may wish to serve rolls from your central that you have not installed during installation. All frontends will serve the rolls they were built with to client frontends, but often it is advantageous to serve other rolls as well.

1. Insert the desired roll CD in drive, mount it as /mnt/cdrom.

2. # rocks-dist copyroll

3. Unmount the CD.

(repeat for each desired roll)

4. # cd /home/install
   # rocks-dist dist

If you have a *.iso image of a roll, you can use the "mount -o loop /mnt/cdrom" command instead of burning the CD and mounting it as in step 1.
