==============================
 Deploying Ceph Configuration
==============================
Ceph's current deployment script does not copy the configuration file you
created from the Administration host to the OSD Cluster hosts. Copy the
configuration file you created (*i.e.,* ``mycluster.conf`` in the example below)
from the Administration host to ``etc/ceph/ceph.conf`` on each OSD Cluster host.

::

	ssh myserver01 sudo tee /etc/ceph/ceph.conf <mycluster.conf
	ssh myserver02 sudo tee /etc/ceph/ceph.conf <mycluster.conf
	ssh myserver03 sudo tee /etc/ceph/ceph.conf <mycluster.conf


The current deployment script doesn't copy the start services. Copy the ``start``
services from the Administration host to each OSD Cluster host. ::

	ssh myserver01 sudo /etc/init.d/ceph start
	ssh myserver02 sudo /etc/init.d/ceph start
	ssh myserver03 sudo /etc/init.d/ceph start

The current deployment script may not create the default server directories. Create
server directories for each instance of a Ceph daemon.

Using the exemplary ``ceph.conf`` file, you would perform the following:

On ``myserver01``::

	mkdir srv/osd.0
	mkdir srv/mon.a

On ``myserver02``::

	mkdir srv/osd.1
	mkdir srv/mon.b

On ``myserver03``::

	mkdir srv/osd.2
	mkdir srv/mon.c

On ``myserver04``::

	mkdir srv/osd.3

.. important:: The ``host`` variable determines which host runs each instance of a Ceph daemon.
