Base OS installation
Our platform is built on top of Ubuntu 12.04.04. The installation iso used was ubuntu-12.04.4-server-amd64.iso. The following settings were applied during the installation process:
- Choose relevant language and keyboard settings
- We expect eth2 is the up-link interface (used to internet access and remote control) and should be interface chosen for installation. It is also expected that eth2 will be connect to a network that will assign it a dhcp address.
- Specify a local USERNAME/PASSWORD combo. Please keep track of this information, it will be required for all setup procedures later on.
- Specify Manual partitioning and partition the disk as follows:
Number Type Size Flags File System Mount Point 1 Primary 20GB Bootable Ext4 / 2 Primary 20GB Ext4 /home 3 Primary 116GB Ext4 /export 4 Primary 4GB Swap
- Leave the http Proxy field empty
- specify NO AUTOMATIC UPDATES. This is important as the auto-update process may break some orbit packages.
- Choose opensssh server in the task selection menu. All other tasks will be installed as seprate packages and do not need to be specified here.
- Answer Yes to installing grub on the local boot disk
- Remove the media (and the drive if needed) and reboot.
- If no explicit instruction is given for a setting, it's safe to assume the default should work.
- This version of Ubuntu does not work well with USB flash disk installations, The best results are with a burned CD/DVD and a USB CD/DVD drive as a the boot medium,refrenced here.
Configure Host Name
Edit the follow files:
- /etc/hosts - Single text string with the fqdn of the console machine
- /etc/hostname - Modify this file to properly resolve the hostname of the machine.
For proper console operation, The console is expected to be connected to 4 Networks. Their respective names and purposes are:
- Data - For experiment traffic, Ideally this is in a separate switch plane to avoid mixing / clobbering control traffic
- CM - Low speed network for soft control of power and terminal output of each node
- Control - Management and control traffic to the Nodes. This network is used for imaging and is needs to be fast. Ideal on a non-blocking switch with good back plane throughput.
- Outside - External access for the console. Mostly for remote control and package updates.
To establish the proper address spaces, we put appropriate rules in the /etc/network/interfaces file. We assume the following mapping of interfaces to subnets:
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The CM network interface auto eth1 iface eth1 inet static address 10.1.0.254 netmask 255.255.255.0 broadcast 10.1.0.255 # The Control network interface auto eth3 iface eth3 inet static address 10.10.0.254 netmask 255.255.255.0 broadcast 10.10.0.255 # The Data network interface auto eth0 iface eth0 inet static address 10.20.0.254 netmask 255.255.255.0 broadcast 10.20.0.255 # The primary network interface auto eth2 iface eth2 inet dhcp
