此时，目录内容如下：
[root@ceph-1 cluster]# ls
ceph.conf ceph-deploy-ceph.log ceph.mon.keyring
8.根据自己的IP配置向ceph.conf中添加public_network，并稍微增大mon之间时差允许范围(默认为0.05s，现改为2s)：
[root@ceph-1 cluster]# echo public_network=192.168.57.0/24 >> ceph.conf
[root@ceph-1 cluster]# echo mon_clock_drift_allowed = 2 >> ceph.conf
[root@ceph-1 cluster]# cat ceph.conf
[global]
fsid = 0248817a-b758-4d6b-a217-11248b098e10
mon_initial_members = ceph-1, ceph-2, ceph-3
mon_host = 192.168.57.222,192.168.57.223,192.168.57.224
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
public_network=192.168.57.0/24
mon_clock_drift_allowed = 2
9.开始部署monitor:
[root@ceph-1 cluster]# ceph-deploy mon create-initial
..
..若干log
[root@ceph-1 cluster]# ls
ceph.bootstrap-mds.keyring ceph.bootstrap-rgw.keyring ceph.conf ceph.mon.keyring
ceph.bootstrap-osd.keyring ceph.client.admin.keyring ceph-deploy-ceph.log
10.查看集群状态：
[root@ceph-1 cluster]# ceph -s
