+使用cephadm bootstrap初始化最小集群
+> cephadm bootstrap 过程是在单一节点上创建一个小型的ceph集群，包括一个ceph monitor和一个ceph mgr，以及监控组件，包括prometheus、node-exporter等。
+```shell
+## 初始化时，指定了mon-ip、集群网段、dashboard初始用户名和密码
+# cephadm bootstrap --mon-ip 192.168.59.241  --cluster-network 10.168.59.0/24 --initial-dashboard-user admin --initial-dashboard-password demo2023

+Enabling client.admin keyring and conf on hosts with "admin" label
+Saving cluster configuration to /var/lib/ceph/2e1228b0-0781-11ee-aa8a-000c2921faf1/config directory
+Enabling autotune for osd_memory_target
+You can access the Ceph CLI as following in case of multi-cluster or non-default config:
+
+       sudo /usr/sbin/cephadm shell --fsid 2e1228b0-0781-11ee-aa8a-000c2921faf1 -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 telemetry on
+
+For more information see:
+
+       https://docs.ceph.com/docs/master/mgr/telemetry/
+
+## 也可以在初始化时指定dashboard用户名和密码  --initial-dashboard-user  admin --initial-dashboard-password demo2023
+# ls /etc/ceph/
+ceph.client.admin.keyring  ceph.conf  ceph.pub  rbdmap
+```
+- ceph.client.admin.keyring  是具有ceph管理员的秘钥
+- ceph.conf  是最小化配置文件
+- ceph.pub  是一个公钥，拷贝到其他节点后，可以免密登录。
+
+> 在5个以上ceph节点时，默认会将其中5个节点当做mon，这可以从`ceph orch ls`中看出来
+```shell
+# ceph orch ls
+NAME           PORTS        RUNNING  REFRESHED  AGE  PLACEMENT  
+alertmanager   ?:9093,9094      1/1  7m ago     46m  count:1    
+crash                           1/1  7m ago     46m  *          
+grafana        ?:3000           1/1  7m ago     46m  count:1    
+mgr                             1/2  7m ago     46m  count:2    
+mon                             1/5  7m ago     46m  count:5    
+node-exporter  ?:9100           1/1  7m ago     46m  *          
+prometheus     ?:9095           1/1  7m ago     46m  count:1  
+```
+
+> 初始化mon后，此时集群还处于WARN状态，没有OSD，MON的数量也才只有1个，MGR也只有1个，所以接下来就是先添加ceph节点。
+```shell
+# ceph -s
+ cluster:
+   id:     67ccccf2-07f6-11ee-a1c2-000c2921faf1
+   health: HEALTH_WARN
+           OSD count 0 < osd_pool_default_size 3
+
+ services:
+   mon: 1 daemons, quorum ceph01 (age 9m)
+   mgr: ceph01.sdqukl(active, since 7m)
+   osd: 0 osds: 0 up, 0 in
+
+ data:
+   pools:   0 pools, 0 pgs
+   objects: 0 objects, 0 B
+   usage:   0 B used, 0 B / 0 B avail
