None ROOT password-Less SSH
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:
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 [email protected] (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?
