Command-Line-Based Management

Command-line tools offer an alternative to Web-based management. A few tasks can only be done from the command line.

Managing Nodes

Once you have a running Eucalyptus system you can add and remove nodes (hosts running Node Controllers) by executing on a Cluster Controller machine:

$EUCALYPTUS/usr/sbin/euca_conf --register-nodes "<nodename1> ... <nodenameN>"

You will be asked for password to login to <nodenameX>: this is needed to propagate the cryptographic keys. Similarly, to remove a node, execute:

$EUCALYPTUS/usr/sbin/euca_conf --deregister-nodes "<nodename1> ... <nodenameN>"

Adding Users

Warning: Please note that boto must be installed for the following commands to function properly. One method of ensuring this is to install Euca2ools.

The following commands assume that the environment variables exported by a 'eucarc' file for an administrative Eucalyptus user have been set.

Users can be added from the command-line with:

$EUCALYPTUS/usr/sbin/euca-add-user USERNAME

possibly with options --email=EMAIL and --admin (all other properties for a user must be set through the Web interface currently).

To delete a user:

$EUCALYPTUS/usr/sbin/euca-delete-user USERNAME
