5.4. Enabling Remote Administration

Installing SSH keys for the root user enables you to access the hosts remotely from your personal workstation. Run the following commands to ensure that the root user's SSH configuration directory exists, and it has the correct permissions on the host:

# mkdir /root/.ssh
# chmod 700 /root/.ssh

On your workstation, you can either use the ssh-keygen command to generate a new key pair, or use an existing public key. In either case, edit the /root/.ssh/authorized_keys file on the host and append the public key, or use the ssh-copy-id command to do the same. For example, on your local workstation, run the following command, replacing the example IP address with the IP address of your broker host:

# ssh-copy-id root@10.0.0.1
