Command Reference › rekey

rekey

The rekey command updates the administrator access keys for a grid to the access keys of the distribution server.

This command has the following format:

aldo rekey grid= name [ controller_ip= ] [ controller_name= ]

grid= name

Specifies the name of the grid for which you want to update the keys.

controller_ip= ipaddr or controller_name= host

Specifies the address or DNS name of the grid controller. This value is not required if the grid was installed from the same distribution server on which the rekey command is being run.

Examples: Update Keys

• This example rekeys the test1 grid:

  aldo rekey grid=test1
  

• This example specifies explicit controller address. The example shows a safer method to rekey a grid. The method works even if the configuration cache on the distribution server is not present.

  aldo rekey grid=test2 controller_ip=10.64.64.64
  

Remarks:

To rekey grids

1. Include the required set of access keys in the ~/.ssh/authorized_keys file on the distribution server.
2. After saving the file and before closing the session, open a new SSH session to the distribution server to verify access.
3. Issue aldo rekey on all grids that you want to rekey.
