cephadm 安装部署 ceph 集群

ceph可以实现的存储方式：块存储：提供像普通硬盘一样的存储，为使用者提供“硬盘”
文件系统存储：类似于NFS的共享方式，为使用者提供共享文件夹
对象存储：像百度云盘一样，需要使用单独的客户端
ceph还是一个分布式的存储系统，非常灵活。如果需要扩容，只要向ceph集中增加服务器即可。ceph存储数据时采用多副本的方式进行存储，生产环境下，一个文件至少要存3份。ceph默认也是三副本存储。
ceph的构成Ceph OSD 守护进程： Ceph OSD 用于存储数据。此外，Ceph OSD 利用 Ceph 节点的 CPU、内存和网络来执行数据复制、纠删代码、重新平衡、恢复、监控和报告功能。存储节点有几块硬盘用于存储，该节点就会有几个osd进程。
Ceph Mon监控器： Ceph Mon维护 Ceph 存储集群映射的主副本和 Ceph 存储群集的当前状态。监控器需要高度一致性，确保对Ceph 存储集群状态达成一致。维护着展示集群状态的各种图表，包括监视器图、 OSD 图、归置组（ PG ）图、和 CRUSH 图。
MDSs: Ceph 元数据服务器（ MDS ）为 Ceph 文件系统存储元数据。
RGW：对象存储网关。主要为访问ceph的软件提供API接口。

You can access the Ceph CLI as following in case of multi-cluster or non-default config:
sudo /usr/sbin/cephadm shell --fsid 976e04fe-9315-11ed-a275-e29e49e9189c -c /etc/ceph/ceph.conf -k /etc/ceph/ceph.client.admin.keyring
Or, if you are only running a single cluster on this host:
sudo /usr/sbin/cephadm shell
Please consider enabling telemetry to help improve Ceph:

ceph orch ls #列出集群内运行的组件
ceph orch host ls #列出集群内的主机
ceph orch ps #列出集群内容器的详细信息
ceph orch apply mon --placement="3 node1 node2 node3" #调整组件的数量
ceph orch ps --daemon-type rgw #--daemon-type：指定查看的组件
ceph orch host label add node1 mon #给某个主机指定标签
ceph orch apply mon label:mon #告诉cephadm根据标签部署mon,修改后只有包含mon的主机才会成为mon，不过原来启动的mon现在暂时不会关闭
ceph orch device ls #列出集群内的存储设备
例如，要在newhost1IP地址10.1.2.123上部署第二台监视器，并newhost2在网络10.1.2.0/24中部署第三台monitor
ceph orch apply mon --unmanaged #禁用mon自动部署
ceph orch daemon add mon newhost1:10.1.2.123
ceph orch daemon add mon newhost2:10.1.2.0/24
