Create the Installer Account and Propagate the SSH Key

The user account needed to start and stop server instances and to load and unload tables to those servers must be configured with passwordless secure shell (SSH).
To reduce the number of operating system (external) accounts, it can be convenient to use the SAS Installer account for both of these purposes.
Implementing passwordless SSH requires that the public key be added to the authorized_keys file across all machines in the cluster. When you create user accounts using SAS High-Performance Computing Management Console, the console propagates the public key across all the machines in the cluster in a single operation.
To create an operating system account and propagate the public key, follow these steps:
  1. Make sure that the SAS High-Performance Computing Management Console server is running. While logged on as the root user, enter the following command from any directory: 
    service sashpcmc status
    (If you are logged on as a user other than the root user, the script returns the message sashpcmc is stopped.) For more information, see To start the SAS High-Performance Computing Management Console server.
  2. Open a web browser and, in the address field, enter the fully qualified domain name for the blade 0 host followed by port 10020.
    For example: http://myserver.example.com:10020
    The Login page appears.

    • Propagate User
    • Generate and Propagate SSH Keys
    When you are finished making your selections, click Create.
    The New User Propagation page appears and lists the status of the create user command. Your task is successful if you see output similar to the following figure.
