Once you have completed this pre-flight checklist, you are ready to begin using
``ceph-deploy``.
Hostname Resolution
===================
Ensure that your admin node can resolve the server node's hostname. ::
ping {server-node}
If you execute ``ceph-deploy`` against the localhost, ``ceph-deploy``
must be able to resolve its IP address. Consider adding the IP address
to your ``/etc/hosts`` file such that it resolves to the hostname. ::
hostname
host -4 {hostname}
sudo vim /etc/hosts
{ip-address} {hostname}
ceph-deploy {command} {hostname}
.. tip:: The ``ceph-deploy`` tool will not resolve to ``localhost``. Use
the hostname.
Summary
=======
Once you have passwordless ``ssh`` connectivity, passwordless ``sudo``,
installed ``ceph-deploy``, and you have ensured appropriate connectivity,
proceed to the `Object Store Quick Start`_.
proceed to the `Storage Cluster Quick Start`_.
.. tip:: The ``ceph-deploy`` utility can install Ceph packages on remote
machines from the admin node!
