Bare metal-based installation: Preparing the Fabric Services System nodes
Setting up key-based authentication from the Fabric Services System deployer VM

Setting up key-based authentication from the Fabric Services System deployer VM

From the deployer VM, enable passwordless login for each node in your deployment.
To enable passwordless login for the nodes, run the following command from the deployer VM:
```
$ ssh-copy-id root@<node IP/FQND>
```
Verify that passwordless login has been enabled.
Log in to each node as root from the deployer VM. If passwordless login has been enabled successfully, the login attempt succeeds without prompting you for a password.
```
$ ssh <node IP/FQND>
```
