- Install the eucalyptus-nc package
sudo apt-get install eucalyptus-nc
- 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 <<EOF bridge_ports $interface bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off EOF sudo /etc/init.d/networking restart
Configure /etc/eucalyptus/eucalyptus.conf with the name of the bridge, and restart the node controller:
sudo sed -i "s/^VNET_BRIDGE=.*$/VNET_BRIDGE=$bridge/" /etc/eucalyptus/eucalyptus.conf sudo /etc/init.d/eucalyptus-nc restart
Note that there are several ways to configure a node to have a bridge as its primary interface, depending on the configuration of your machine. We show an example set of steps here but you will need to take care to ensure that this example configuration does not conflict with your local configuration if you wish to use it.
Finally, you need to install the Cluster Controller's eucalyptus user's public ssh key into the Node Controller's eucalyptus user's authorized_keys file. The easiest way to do this:
On the Node Controller, temporarily set a password for the eucalyptus user:
sudo passwd eucalyptus
- Then, on the Cluster Controller:
sudo -u eucalyptus ssh-copy-id -i ~eucalyptus/.ssh/id_rsa.pub eucalyptus@<IP_OF_NODE>
You can now remove the password of the eucalyptus account on the Node:
sudo passwd -d eucalyptus
