A Red Hat training course is available for Red Hat Ceph Storage

Appendix C. Installing the Ceph Command Line Interface

The Ceph command-line interface (CLI) enables administrators to execute Ceph administrative commands. The CLI is provided by the ceph-common package and includes the following utilities:

  • ceph
  • ceph-authtool
  • ceph-dencoder
  • rados

Prerequisites

  • A running Ceph storage cluster, preferably in the active + clean state.

Procedure

  1. On the client node, enable the Red Hat Ceph Storage 3 Tools repository: 

    [root@gateway ~]# subscription-manager repos --enable=rhel-7-server-rhceph-3-tools-els-rpms

  2. On the client node, install the ceph-common package: 

    # yum install ceph-common

  3. From the initial monitor node, copy the Ceph configuration file, in this case ceph.conf, and the administration keyring to the client node:

    Syntax

    # scp /etc/ceph/<cluster_name>.conf <user_name>@<client_host_name>:/etc/ceph/
# scp /etc/ceph/<cluster_name>.client.admin.keyring <user_name>@<client_host_name:/etc/ceph/

    Example

    # scp /etc/ceph/ceph.conf root@node1:/etc/ceph/
# scp /etc/ceph/ceph.client.admin.keyring root@node1:/etc/ceph/

    Replace <client_host_name> with the host name of the client node.
