Whether you want to provide RESTful object services and/or block devices to a cloud solution, deploy a CephFS filesystem or use Ceph for another purpose, all Ceph clusters begin with setting up your host computers, network and the Ceph Object Store. A Ceph object store cluster has three essential daemons:
Step 1: Preflight
Client and server machines may require some basic configuration work prior to deploying a Ceph cluster. You can also avail yourself of help from the Ceph community by getting involved.
Step 2: Object Store
Once you’ve completed your preflight checklist, you should be able to begin deploying a Ceph cluster.
Step 3: Ceph Client(s)
Most Ceph users don’t store objects directly. They typically use at least one of Ceph block devices, the CephFS filesystem, and the RESTful gateway.
