3.安装ceph(所有节点执行)

yum install -y ceph ceph-deploy

4.初始化mon节点(deploy节点执行)

ceph-deploy new ceph01 ceph02 ceph03

5.初始化mon(deploy节点执行)

6.修改集群文件(deploy节点执行)

cd /etc/ceph/

ceph-deploy --overwrite-conf config push ceph01 ceph02 ceph03

7.配置admin节点

cd /etc/ceph/
ceph-deploy admin ceph01 ceph02 ceph03

[root@ceph01 ~]# ceph -s
