- osd 3 : osd0, osd1, osd2

- mgmt : mgmt

- mds : mds0

1. /etc/hosts

2. 각 노드들 hostname 수정

3. ceph 유저생성

# sudo useradd -d /home/ceph -m ceph

# sudo passwd ceph

# echo "ceph ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/ceph

# sudo chmod 0440 /etc/sudoers.d/ceph

4. SSH 인증키 (mgmt 서버에서 패스워드 없이 각노드들 컨트롤)

모든 노드들 진행

ceph@mgmt:~$ ssh-keygen

Generating public/private rsa key pair.

Enter file in which to save the key (/home/ceph/.ssh/id_rsa):

Created directory '/home/ceph/.ssh'.

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/ceph/.ssh/id_rsa.

Your public key has been saved in /home/ceph/.ssh/id_rsa.pub.

The key fingerprint is:
