Creating root and vertica_dba Accounts
vertica_dba accounts must have their own RSA or Digital Signature Algorithm (DSA) keysets.
This requirement is necessary only if the local security policy has configured SSH
vertica_dbapublic key(s) must be in the
/var/db/vertica/.ssh/authorized_keysfile on all Analytics nodes. Create them if they don't exist.
rootpublic key(s) must be in the
/var/db/vertica/.ssh/authorized_keysfiles on all Analytics nodes. Create them if they don't exist.
rootaccounts on the Analytics nodes may have different keysets, depending on local security policy. In this case, public keys from the root account on all Analytics nodes need to be added to both
authorized_keysfiles noted above.
