Install Ceph packages on each server:
sudo apt-get update
sudo apt-get install ceph-deploy
Create a Ceph cluster on a server:
mkdir my-ceph-cluster
cd my-ceph-cluster
ceph-deploy new <第一台服务器的主机名>
Install Ceph packages and dependencies on each server:
ceph-deploy install --release octopus <第一台服务器的主机名> <第二台服务器的主机名> <第三台服务器的主机名>
Initialize Ceph monitors on each server:
ceph-deploy mon create-initial
Add OSD nodes on each server:
ceph-deploy osd create --data /dev/sdb <第一台服务器的主机名>
ceph-deploy osd create --data /dev/sdb <第二台服务器的主机名>
ceph-deploy osd create --data /dev/sdb <第三台服务器的主机名>
Generate Ceph configuration files and keys on one server:
ceph-deploy admin <第一台服务器的主机名>
Copy the Ceph configuration files and keys to the correct location on each server:
sudo cp ceph.client.admin.keyring /etc/ceph/
sudo cp ceph.conf /etc/ceph/
sudo chown ceph:ceph /etc/ceph/ceph.client.admin.keyring
Start the Ceph service on each server:
sudo systemctl enable ceph-mon.target
sudo systemctl enable ceph-osd.target
sudo systemctl start ceph-mon.target
sudo systemctl start ceph-osd.target
Create a Ceph storage pool on a server:
ceph osd pool create my-pool 128 128
Verify the status of the Ceph cluster:
ceph -s
