+> 将ceph镜像导出到其他ceph节点上

+> 将ceph.pub公钥拷贝到其他ceph节点
+```shell
+# ssh-copy-id -f -i /etc/ceph/ceph.pub ceph02
+# ssh-copy-id -f -i /etc/ceph/ceph.pub ceph03
+# ssh-copy-id -f -i /etc/ceph/ceph.pub ceph04
+# ssh-copy-id -f -i /etc/ceph/ceph.pub ceph05

+## 也可以用以下命令拷贝，在ceph01上操作
+# for i in {2..5};do ssh-copy-id -f -i /etc/ceph/ceph.pub ceph0$i;done

+> 使用cephadm将主机添加到存储集群中,执行添加节点命令后，会在目标节点拉到ceph/node-exporter镜像，需要一定时间，所以可提前在节点上将镜像导入。
+```shell
+# cephadm shell ceph orch host add ceph02 192.168.59.242 --labels=mon,mgr
+# ceph orch host add ceph03 192.168.59.243 --labels=mon
+# ceph orch host add ceph04 192.168.59.244
+# ceph orch host add ceph05 192.168.59.245
+```
+> 查看加入到集群的节点
+```shell
+# ceph orch host ls
