is easy. To install packages on each Ceph Node in your cluster. You may
ceph-deploy to install Ceph for your storage cluster, or use package
management tools. You should install Yum Priorities for RHEL/CentOS and other
distributions that use Yum if you intend to install the Ceph Object Gateway or
Deploy a Cluster Manually¶
Once you have Ceph installed on your nodes, you can deploy a cluster manually. The manual procedure is primarily for exemplary purposes for those developing deployment scripts with Chef, Juju, Puppet, etc.
As new versions of Ceph become available, you may upgrade your cluster to take advantage of new functionality. Read the upgrade documentation before you upgrade your cluster. Sometimes upgrading Ceph requires you to follow an upgrade sequence.
