Passwordless SSH

If Kinetica is installed in a clustered environment, configuring passwordless SSH will make management considerably easier. Run the following command on the head node to set up passwordless SSH between the head node and the worker nodes for the gpudb users created during deployment:

sudo /opt/gpudb/core/bin/gpudb_hosts_ssh_copy_id.sh

If necessary, you can copy SSH public keys for non-gpudb users to all the hosts in a cluster (made available with gpudb_hosts_addresses.sh) using the ssh-copy-id tool that is part of OpenSSH:

ssh-copy-id -i ~/.ssh/<public_key_name> <user>@<hostname>
