Eucalyptus Management (1.6)
This part of the Administrator's Guide describes tasks that can be performed on a completed Eucalyptus installation, whether it was installed from source or from packages.
1. Image Management To use Eucalyptus, images must be added and registered with the system. We have a document detailing the steps of this process in Image Management.
2. Node Management Once you have a running Eucalyptus system you can add and remove nodes (systems running Node Controllers) using
$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
$EUCALYPTUS/usr/sbin/euca_conf --deregister-nodes "<nodename1> ... <nodenameN>" 3. User Management 3.1 User sign-up Users interested in joining the cloud should be directed to the front-end Web page (note the https prefix!):
https://your.front.end.hostname:8443/
As soon as the administrator logs in for the first time and enters the email address to be used for application requests, thus activating the Web site for use by others, the login box of the Web site will have an "Apply for account" link underneath it. After a user fills out the application form, an email is sent to the administrator, containing two URLs, one for accepting and one for rejecting the user.
Note that there is no authentication performed on the people who fill out the form. It is up to the administrator to perform this authentication! The only "guarantee" the administrator has is that the account will not be active unless the person who requested the account (and, hence, knows the password) can read email at the submitted address. Therefore, if the administrator is willing to give the account to the person behind the email address, it is safe to approve the account. Otherwise, the administrator may use the additional information submitted (such as the telephone number, project PI, etc.) to make the decision.
Accepting or rejecting a signup request causes an email message to be sent to the user who made the request. In the case of an acceptance notification, the user will see a link for activating the account. Before activating the account, the user will have to log in with the username and password that they chose at signup.
3.2 Adding users Users can be added by the administrator explicitly by logging into the Eucalyptus web interface, as an administrative user, clicking the 'Users' tab, clicking on the 'Add User' button, and filling out the same user form that a user would fill out if they applied themselves. The user will be automatically 'approved' using this method, but their account will not be active until the user clicks the link that is sent via email similar to the above method.
3.3 Managing users If the administrator wishes to disable or delete a user, they can do so through the web interface, as an administrative user, clicking the 'Users' tab, and clicking either the 'disable' or 'delete' link respectively.
