視頻鏈接：添加ceph節(jié)點

> 將ceph鏡像導(dǎo)出到其他ceph節(jié)點上
```shell
# docker images ?|grep -v "REPOSITORY" |awk '{print $1":"$2}' |xargs docker save -o ceph-images.tar
# for i in {2..5};do scp ceph-images.tar ceph0$i:/root/;done

## 在ceph02-05上導(dǎo)入鏡像
# docker load -i ceph-images.tar
```
>
> 將ceph.pub公鑰拷貝到其他ceph節(jié)點
```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貝，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將主機(jī)添加到存儲集群中,執(zhí)行添加節(jié)點命令后，會在目標(biāo)節(jié)點拉到ceph/node-exporter鏡像，需要一定時間，所以可提前在節(jié)點上將鏡像導(dǎo)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
```
> 查看加入到集群的節(jié)點
```shell
# ceph orch host ls
