=======================
Basic Ceph Client Setup
=======================
Client machines require some basic configuration to interact with
Ceph clusters. This section describes how to configure a client machine
so that it can interact with a Ceph cluster.
.. note::
Most client machines need to install only the `ceph-common` package
and its dependencies. Such a setup supplies the basic `ceph` and
`rados` commands, as well as other commands including `mount.ceph`
and `rbd`.
Config File Setup
=================
Client machines usually require smaller configuration files (here
sometimes called "config files") than do full-fledged cluster members.
To generate a minimal config file, log into a host that has been
configured as a client or that is running a cluster daemon, and then run the following command:
.. prompt:: bash #
ceph config generate-minimal-conf
This command generates a minimal config file that tells the client how
to reach the Ceph monitors. The contents of this file should usually
be installed in ``/etc/ceph/ceph.conf``.
Keyring Setup
=============
Most Ceph clusters run with authentication enabled. This means that
the client needs keys in order to communicate with the machines in the
cluster. To generate a keyring file with credentials for `client.fs`,
log into an running cluster member and run the following command:
.. prompt:: bash $
ceph auth get-or-create client.fs
The resulting output is directed into a keyring file, typically
``/etc/ceph/ceph.keyring``.
To gain a broader understanding of client keyring distribution and administration, you should read :ref:`client_keyrings_and_configs`.
To see an example that explains how to distribute ``ceph.conf`` configuration files to hosts that are tagged with the ``bare_config`` label, you should read the section called "Distributing ceph.conf to hosts tagged with bare_config" in the section called :ref:`etc_ceph_conf_distribution`.
