==================================
Deploying the Ceph Configuration
==================================
Ceph's ``mkcephfs`` 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
if you are using ``mkcephfs`` to deploy Ceph.
::
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 does 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``::
sudo mkdir srv/osd.0
sudo mkdir srv/mon.a
On ``myserver02``::
sudo mkdir srv/osd.1
sudo mkdir srv/mon.b
On ``myserver03``::
sudo mkdir srv/osd.2
sudo mkdir srv/mon.c
On ``myserver04``::
sudo mkdir srv/osd.3
.. important:: The ``host`` variable determines which host runs each instance of a Ceph daemon.
