• Basic installation of Debian Squeeze

Networking

• edit /etc/networks/interfaces Note that at some point eth1 should be configured by DHCP, it is on the UCD LAN and must be registered correctly (update MAC address with services). eth0 is the internal network.

# The loopback network interface
auto lo eth0 eth1

iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
        address 192.168.21.254
        netmask 255.255.255.0
        gateway 192.168.21.1

iface eth1 inet static
        address 193.1.132.124
        netmask 255.255.252.0
        gateway 193.1.132.1

• set resolv.conf:

nameserver 137.43.116.19
nameserver 137.43.116.17
nameserver 137.43.105.22
domain ucd.ie
search ucd.ie

• Install non-free linux firmware for network interface (eth0). Edit /etc/apt/sources.list including the lines:

deb http://ftp.ie.debian.org/debian/ squeeze main contrib non-free
deb-src http://ftp.ie.debian.org/debian/ squeeze main contrib non-free

• Install firmware-linux:

  apt-get update && apt-get install firmware-linux
  

• follow the guide to installing Clonezilla here. Essentially:
  • add repository key

    wget -q http://drbl.sourceforge.net/GPG-KEY-DRBL -O- | apt-key add -
    

  • the line add to /etc/apt/sources.list:

    deb http://drbl.sourceforge.net/drbl-core drbl stable
    

  • run:

    apt-get update && apt-get install drbl && /opt/drbl/sbin/drbl4imp
    

  • accept default options to drbl4imp.

• After Clonezilla has installed edit /etc/dhcpd3/dhcpd.conf, adding all entries for test nodes hcl07 and hcl03. Also ensure these nodes have been removed from the inplace heterogeneous.ucd.ie server so that they are only served by one machine.

Install NIS

Copy users from passwd, groups and shadow from /etc on hcl01.

Install nis.

Edit /etc/defaultdomain so that it contains:

heterogeneous.ucd.ie

Edit /etc/defaults/nis so that it contains:

# Are we a NIS server and if so what kind (values: false, slave, master)
NISSERVER=master

Edit /etc/ypserv.securenets so that is contains:

# allow connects from local
255.0.0.0	127.0.0.0
# allow connections from heterogeneous subnet
255.255.255.0 192.168.21.0

The NIS host is also a client of itself, so do the client set up as follows:

Edit /etc/hosts end ensure the NIS Master is listed

192.168.21.254		heterogeneous.ucd.ie	heterogeneous

Edit /etc/yp.conf and ensure that it contains:

domain heterogeneous.ucd.ie server localhost

Edit /etc/passwd adding a line to the end that reads: +::::::. Edit /etc/group with a line +::: at the line.

The NIS Makefile will not pull userid and groupids that are lower than a certain value, we must set this to 500 in /var/yp/Makefile

MINUID=500
MINGID=500

Start the ypbind and yppasswd services. Then initialise the NIS database:

/usr/lib/yp/ypinit -m

Accept defaults at prompts.

Now start other NIS services

service nis start

Installing Ganglia Frontend

Install the packages gmetad and ganglia-webfrontend.

Configure the front end by appending to /etc/apache2/apache2.conf, the following:

Include /etc/ganglia-webfrontend/apache.conf

Configure gmetad by adding to the /etc/ganglia/gmetad.conf, the following line:

data_source "HCL Cluster" hcl07

After all packages are configured execute:

service apache2 restart
service gmetad restart

Pointing your browser to here should display the monitoring page for HCL Cluster. gmond must also be installed and configured on the cluster nodes.
