(備註：此一共用到4臺機器。分別命名為ceph-admin ,ceph0,ceph1,ceph2.其中ceph-admin作為deploy 機器用於部署，ceph-admin,ceph0作為mon,ceph1，作為OSD，ceph2作為元資料伺服器）

0.配置IP/主機名

1.在每臺機器上建立ceph使用者，

udo useradd -d /home/ceph -m ceph
sudo passwd ceph

2.在每個Ceph節點中為使用者增加 root 許可權

3.安裝ssh伺服器

sudo yum install openssh-server

4.用無密碼的SSH連線到每個Ceph節點來配置你的 ceph-deploy 管理節點. 保留密碼為空:

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.

5.複製祕鑰至每個Ceph節點.

6.修改你的ceph-deploy 管理節點的 ~/.ssh/config 檔案使它能像你建立的使用者(比如, ceph)一樣記錄至Ceph節點 .

7.更新你的倉庫並安裝ceph-deploy  (ceph-admin節點上安裝ceph-deploy，用於部署)
