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 + cleanstate.
Procedure
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-rpms
On the client node, install the
ceph-commonpackage:# yum install ceph-common
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.
