Chapter 7. Install Ceph

Ensure that ceph-deploy is pointing to the cephdeploy.conf file generated by calamari-ctl initialize (e.g., in the exemplary ~/ceph-config directory, the /opt/ICE directory, etc.). Otherwise, you may not receive packages from the local repository. Ideally, you should run ceph-deploy from the directory where you keep your configuration (e.g., the examplary ~/ceph-config) so that you can maintain a {cluster-name}.log file with all the commands you have executed with ceph-deploy. To install Ceph on remote nodes, first use --repo option with ceph-deploy to install the repo files on remote nodes.

For admin node, execute:

ceph-deploy install <ceph-node>

For example:

ceph-deploy install admin-node

For other nodes, execute:

ceph-deploy install --repo <ceph-node> [<ceph-node> ...]
ceph-deploy install <ceph-node> [<ceph-node> ...]

For example:

ceph-deploy install --repo node1 node2 node3 node4
ceph-deploy install node1 node2 node3 node4

The ceph-deploy utility will install Ceph on each node. NOTE: If you use ceph-deploy purge, you must re-execute these steps to re-install Ceph.
