ComputeMode server appliance

Retrieving virtual appliances

• To retrieve the appliance for the Virtualbox system:

wget http://computemode.imag.fr/files/appliances/ComputeMode_Appliance_2.0_vbox_64bits.zip

for VMware:

wget http://computemode.imag.fr/files/appliances/ComputeMode_Appliance_2.0_vmware_64bits.zip

• Then, unzip the appliance:

For Virtualbox:

unzip ComputeMode_Appliance_2.0_vbox.zip

For VMware:

unzip ComputeMode_Appliance_2.0_vmware.zip

Configuration of your new CMserver appliance

For VirtualBox:

• Create and configure a new virtual machine with virtualbox:

Create a new virtual appliance

Configuration of the new appliance

Configuration of the new appliance

Configuration of hard disk

Configuration of the new appliance

Configuration of the new appliance

• A new appliance is now available, you now have to configure the network:

Configuration of the network

You may define two interfaces: the first interface bridged with your local interface eth0 for example, to access to your server through a ssh connection:

Configuration of your bridged connection

The second, with a NAT configuration, to allow the cmserver to access to the outside (to upgrade packages for example):

Configuration of your bridged connection

Finally you have to configure your local network. The eth0 (the bridged) interface have to access to the CMserver network, this is an example of how to configure the /etc/nerwork/interfaces file:

Configuration of the /etc/network/interfaces file

Finishing the installation: configuration of the cmserver

• You just have to start your appliance and log-in with the following credentials (be carrefull with the US default keyboard map)

login: root
password: icatis

• Once logged, a script is executed the first time the appliance is booted to configure: timezone, keyboard map...:

Execution of the cmaskconfig script during the first boot

• To finish the installation, just edit the /etc/nerwork/interfaces file from the cmserver and configure your two new interfaces like following:

# The bridged interface:
auto eth0
iface eth0 inet static
       address 172.28.255.253
       netmask 255.255.0.0
# The NATed interface:
auto eth1
iface eth1 inet dhcp

• Just reboot the cmserver to complete your installation

How to create nodes to test the appliance

• You can quickly create a diskless node for the computemode cluster:

Creation of a diskless node

Creation of a diskless node

Creation of a diskless node

• and then configure the network of this node:

Network configuration of the diskless node

Configure the first interface bridged with your local eth0 interface:

Network configuration of the diskless node

And to finish configure the boot order of your node to set the network boot in first:

Boot order of the diskless node
