Physical Assembly
• Frontend
– Nodes of this type are exposed to the outside
world.
– Many services (NFS, NIS, DHCP, NTP, MySQL,
HTTP, ...) run on these nodes.
• Compute
– These are the workhorse nodes.
• Ethernet Network
– All compute nodes are connected with ethernet
on the private network.
The every machine in cluster called “node”

Install compute node
•
•
•
Log-in to Frontend as root
Open a Terminal program (Right click
opn desktop and select “Terminal”)
Run the insert-thers command
–
•
# insert-ethers
you will see next screen:

Install compute node (cont’d)
• Select “Compute”
25

Install compute node (cont’d)
• When the frontend
machine receives the
DHCP request from
the compute node
• will be displayed for a
few seconds and then
you'll see the
following:

Install compute node (cont’d)
• Press F10 for exit of insert-ethers
• Default name of compute node is compute-X-X
• The first digit call cabinet. It same the cluster
group number.
• For install another cabinet you can restart the
insert-ethers again and use option –cabinet
– # insert-ethers --cabinet=1
• If you use before command you can get compute
node in cabinet “compute-1-X”
27

Remove a compute node from the cluster
• Command
– # insert-ethers --remove="[your compute node
name]"
• Example : remove compute-0-1
– # insert-ethers --remove="compute-0-1"

Rocks Command
• Rocks command line is a set of command
used to manipulate a ROCKS Cluster
• Example
– rocks run host /sbin/poweroff
• For an example the poweroff command is
distributed to all compute node in cluster.
And let few minute all compute node is
shutdown
