Installing the Eucalyptus Node Service on a running Ubuntu system consists of doing the following on one or more systems: 1. [[https://help.ubuntu.com/10.04/serverguide/C/installation.html|Install Ubuntu 10.04 Server]] 1. Update to the most current state in the Ubuntu archive: {{{ sudo apt-get update sudo apt-get dist-upgrade }}} 1. Install the eucalyptus-nc package {{{ sudo apt-get install eucalyptus-nc }}} 1. Configure the system's primary ethernet interface as a bridge. The node controller will attach virtual network interfaces to this bridge for VM that is started before it to enable network connectivity. * Note: Remember the name of your node's bridge device (we assume the name of your bridge device is "br0" for the rest of this document). * For details on configuring a bridge, see: [[http://doc.ubuntu.com/ubuntu/serverguide/C/network-configuration.html]] * The following script should configure your bridge correctly in most setups: {{{ interface=eth0 bridge=br0 sudo sed -i "s/^iface $interface inet \(.*\)$/iface $interface inet manual\n\nauto br0\niface $bridge inet \1/" /etc/network/interfaces sudo tee -a /etc/network/interfaces < }}} * You can now remove the password of the ''eucalyptus'' account on the Node: {{{ sudo passwd -d eucalyptus }}} The following diagram depicts what your setup should now resemble: {{http://pompone.cs.ucsb.edu/~nurmi/images/euca-topo.png}}
