Edit the ``/etc/hosts`` file to contain the following:
.. code-block:: ini
# controller
10.0.0.11 controller
# compute1
10.0.0.31 compute1
# block1
10.0.0.41 block1
# object1
10.0.0.51 object1
# object2
10.0.0.52 object2
.. warning::
Some distributions add an extraneous entry in the ``/etc/hosts``
file that resolves the actual hostname to another loopback IP
address such as ``127.0.1.1``. You must comment out or remove this
entry to prevent name resolution problems. **Do not remove the
127.0.0.1 entry.**
.. note::
To reduce complexity of this guide, we add host entries for optional
services regardless of whether you choose to deploy them.
