> 将ceph镜像导出到其他ceph节点上
|
||
```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上导入镜像
|
||
# docker load -i ceph-images.tar
|
||
```

> 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
|
||
