- Preflight Checklist
-=====================
-
-.. versionadded:: 0.60
-
-This **Preflight Checklist** will help you prepare an admin node for use with
-``ceph-deploy``, and server nodes for use with passwordless ``ssh`` and
-``sudo``.
-
-Before you can deploy Ceph using ``ceph-deploy``, you need to ensure that you
-have a few things set up first on your admin node and on nodes running Ceph
-daemons.
-
-
-Install an Operating System
-===========================
-
-Install a recent release of Debian or Ubuntu (e.g., 12.04 LTS, 14.04 LTS) on
-your nodes. For additional details on operating systems or to use other
-operating systems other than Debian or Ubuntu, see `OS Recommendations`_.
-
-
-Install an SSH Server
-=====================
-
-The ``ceph-deploy`` utility requires ``ssh``, so your server node(s) require an
-SSH server. ::
-
- sudo apt-get install openssh-server
-
-
-Create a User
-=============
-
-Create a user on nodes running Ceph daemons.
-
-.. tip:: We recommend a username that brute force attackers won't
- guess easily (e.g., something other than ``root``, ``ceph``, etc).
-
-::
-
- ssh user@ceph-server
- sudo useradd -d /home/ceph -m ceph
- sudo passwd ceph
-
-
-``ceph-deploy`` installs packages onto your nodes. This means that
-the user you create requires passwordless ``sudo`` privileges.
-
-.. note:: We **DO NOT** recommend enabling the ``root`` password
- for security reasons.
-
-To provide full privileges to the user, add the following to
-``/etc/sudoers.d/ceph``. ::
-
- echo "ceph ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/ceph
- sudo chmod 0440 /etc/sudoers.d/ceph
-
-
-Configure SSH
-=============
-
-Configure your admin machine with password-less SSH access to each node
-running Ceph daemons (leave the passphrase empty). ::
-
- ssh-keygen
- Generating public/private key pair.
- Enter file in which to save the key (/ceph-client/.ssh/id_rsa):
- Enter passphrase (empty for no passphrase):
- Enter same passphrase again:
- Your identification has been saved in /ceph-client/.ssh/id_rsa.
- Your public key has been saved in /ceph-client/.ssh/id_rsa.pub.
-
-Copy the key to each node running Ceph daemons::
-
- ssh-copy-id ceph@ceph-server
-
-Modify your ~/.ssh/config file of your admin node so that it defaults
-to logging in as the user you created when no username is specified. ::
-
- Host ceph-server
- Hostname ceph-server.fqdn-or-ip-address.com
- User ceph
-
-
-Install ceph-deploy
-===================
-
-To install ``ceph-deploy``, execute the following::
-
- wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -
- echo deb http://ceph.com/debian-dumpling/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
- sudo apt-get update
- sudo apt-get install ceph-deploy
-
-
-Ensure Connectivity
-===================
-
-Ensure that your Admin node has connectivity to the network and to your Server
-node (e.g., ensure ``iptables``, ``ufw`` or other tools that may prevent
-connections, traffic forwarding, etc. to allow what you need).
-
-
-Once you have completed this pre-flight checklist, you are ready to begin using
-``ceph-deploy``.
