The Ceph administration node is mainly used for running ceph-deploy: this tool is specifically designed to provision Ceph clusters with ease. It’s not the only way you can create a Ceph cluster, just the most simple.Once all the nodes have been configured with the password-less sudo-capable ceph user, you need to verify that the administration node is able to reach every node by its hostname, since these will be the names of the nodes registered in Ceph. Which means, a command like “ping mon1” should be successful for each of the nodes. If not, check again your dns servers and/or modify the hosts file.With all the networking verified, install ceph-deploy using the user ceph. On a CentOS 7 machine like mine, you need to first add the Ceph repository. If you are running Ubuntu, check the Ceph pre-flight page.
