ClusterPack Tutorial

Background
This tool is the driver that installs and configures appropriate components on every Compute Node.
z
Registers Compute Nodes with SCM and SIM on the Management Server.
z
Pushes agent components to all Compute Nodes.
z
Sets up each Compute Node as NTP client, NIS client, and NFS client.
z
Starts necessary agents in each of the Compute Nodes.
z
Modifies configuration files on all Compute Nodes to enable auto-startup of agents after
reboots.
z
Allows for the configuration of additional networks with clnetworks
z
Prints a PASS diagnostic message if all configuration steps are successful.
clnetworks
Each Compute Node is known to the Management Server through the IP address and specified to
manager_config. These interfaces are collectively known as the Cluster Network. This term can be
somewhat confusing when a cluster consists of both private nodes and public nodes. This is possible, for
example, when an initial set of Compute Nodes is created on a private network and then additional node
s
outside the private network are added using -a. The IP address of each Compute Node known by the
Management Server makes up the Cluster Network.
ClusterPack includes a utility to configure additional networks on all of the Compute Nodes. These
networks, like the Cluster Network, refer to a logical collection of interfaces/IP addresses and not to a
p
hysical network. However, they must share a common netmask. The concept of a network is defined as:
z
A name (for reference only)
z
A subset of the nodes in the cluster
z
A network interface for each node in the subset
z
An IP address for each interface
z
A name extension that is added to the hostname of each machine and associated with each
host's interface.
z
A netmask
To define additional networks, use the command clnetworks. This tool is also called from compute_conf
i
clnetworks provides a text-
b
ased interface for selecting nodes, network interfaces and IP addresses. It gu
i
the user through the creation of a network. It is also possible to modify an existing network. When you h
a
finished creating or updating networks, clnetworks will ensure that each interface specified is configured
correctly and ensure the proper entries in each host's /etc/hosts file.
Overview
The compute_config program will register the nodes with various programs.
