None ROOT password-Less SSH

Hello,

one of our show-stopper in production is to have password-less SSH for ROOT between vertica servers.

We found a by-pass and to use DBADMIN for install_vertica using additional two parameters:

‘--no-ssh-key-install’

‘--ssh-identity’

using dbadmin user rather than root.

This phase actually worked !!!

However, the second phase executed by dbadmin username : supposed to create the DB instance ,  using admintools CLI

It keep prompting : “Enter password for dbadmin@192.168.249.212 (3 attempts left):”

Pressing enter, and the program will continue and the DB will be created.

Here the actual command that I’m using:

/opt/vertica/bin/admintools -t create_db -s apps-vertica-node-1,apps-vertica-node-2,apps-vertica-node-3 -d  verticaDB -l /opt/vertica/config/licensing/Vertica_IPP.dat -P always

Even if I am adding –p ‘<dba-password>’ , it keep prompting the above request.

BTW, SSH from machine 3 to 1,2 as dbadmin worked fine without password.

Any ideas how to overcome/by-pass this prompt issue?

Thank You.
