ceph命令应用
记录：337
场景：在CentOS 7.9操作系统上，在ceph集群中，使用ceph命令查看ceph集群信息，以及mon、mgr、mds、osd、rgw等组件信息。
版本：
操作系统：CentOS 7.9
ceph版本：ceph-13.2.10
名词：
ceph：ceph集群的工具命令。
1.基础环境
在规划集群主机上需安装ceph-deploy、ceph、ceph-radosgw软件。
(1)集群主节点安装软件
安装命令：yum install -y ceph-deploy ceph-13.2.10
安装命令：yum install -y ceph-radosgw-13.2.10
解析：集群中主节点安装ceph-deploy、ceph、ceph-radosgw软件。
(2)集群从节点安装软件
安装命令：yum install -y ceph-13.2.10
安装命令：yum install -y ceph-radosgw-13.2.10
解析：集群中从节点安装ceph、ceph-radosgw软件。
2.命令应用
ceph命令，在集群主节点的/etc/ceph目录下使用。
(1)查看ceph版本
命令：ceph --version
解析：查的当前主机安装ceph的版本。
(2)查看集群状态
命令：ceph -s
解析：查看集群状态，使用频率高。
(3)查看集群实时状态
命令：ceph -w
解析：查看集群实时状态，使用命令时，控制台实时监控集群变化。
(4)查看mgr服务
命令：ceph mgr services
解析：命令会打印出："dashboard": "https://app162:18443/"；使用浏览器就能登录dashboard。
(5)查看mon 状态汇总信息
命令：ceph mon stat
解析：汇总mon状态。
(6)查看mds状态汇总信息
命令：ceph mds stat
解析：汇总mds状态。
(7)查看osd状态汇总信息
命令：ceph osd stat
解析：汇总osd状态。
(8)创建pool
命令：ceph osd pool create hz_data 16
解析：创建一个存储池，名称hz_data，分配16个pg。
(9)查看存储池
命令：ceph osd pool ls
解析：能看到存储列表。
(10)查看pool的pg数量
命令：ceph osd pool get hz_data pg_num
解析：查看pool的pg_num数量。
(11)设置pool的pg数量
命令：ceph osd pool set hz_data pg_num 18
解析：设置pool的pg_num数量。
(12)删除pool
命令：ceph osd pool delete hz_data hz_data --yes-i-really-really-mean-it
解析：删除pool时，pool的名称需要传两次。
(13)创建ceph文件系统
命令：ceph fs new hangzhoufs xihu_metadata xihu_data
解析：使用ceph fs new创建ceph文件系统；文件系统名称：hangzhoufs；存储池xihu_data和xihu_metadata。
(14)查ceph文件系统
命令：ceph fs ls
解析：查看ceph文件系统，打印文件系统名称和存储池。
(15)查ceph文件系统状态
命令：ceph fs status
解析：查ceph文件系统状态，打印文件系统的Pool的信息、类型等。
(16)删除ceph文件系统
命令：ceph fs rm hangzhoufs --yes-i-really-mean-it
解析：hangzhoufs是已创建的ceph文件系统名称。
(17)查看服务状态
命令：ceph service status
解析：查看服务状态，查看服务最后一次反应时间。
(18)查看节点quorum状态
命令：ceph quorum_status
解析：查看节点quorum状态。
(19)查看pg状态
命令：ceph pg stat
解析：查看pg状态；pg，placement group。
(20)查看pg清单
命令：ceph pg ls
解析：列出所有pg。
(21)查看osd磁盘信息
命令：ceph osd df
解析：打印osd磁盘信息，包括容量，可用空间，已经使用空间等。
3.命令帮助手册
(1)ceph帮助命令
命令：ceph --help
解析：查看ceph支持全部命令和选项，在实际工作中，查看这个手册应该是必备之选。
