前端运维人员已经搭建ceph分布式存储系统环境，使用的设备分别是211、212、213，结构如图：
登录系统服务端，创建用户
[root@node-2 ~]# ceph auth get-or-create client.zyj mon 'allow r' osd 'allow rw pool=tmVideoPool' -o zyj.keyring
[root@node-2 ~]# ceph auth ls
client.zyj
key: AQCeTBhjfjuSChAA+C9cwKEpKP+AElI4U6X0Qw==
caps: [mon] allow r
caps: [osd] allow rw pool=tmVideoPool
这里使用了admin用户，从服务端/etc/ceph目录内以下这两个配置文件拷贝到客户端的/etc/ceph目录下
centos7系统下ceph客户端环境搭建：
添加yum源，/etc/yum.repos.d/ceph.repo，内容为：
[Ceph] name=Ceph packages for $basearch baseurl=https://mirrors.aliyun.com/ceph/rpm-mimic/el7/$basearch enabled=1 gpgcheck=1 type=rpm-md gpgkey=https://mirrors.aliyun.com/ceph/keys/release.asc [Ceph-noarch] name=Ceph noarch packages baseurl=https://mirrors.aliyun.com/ceph/rpm-mimic/el7/noarch enabled=1 gpgcheck=1 type=rpm-md gpgkey=https://mirrors.aliyun.com/ceph/keys/release.asc [ceph-source] name=Ceph source packages baseurl=http://mirrors.aliyun.com/ceph/rpm-mimic/el7/SRPMS enabled=1 gpgcheck=1 type=rpm-md gpgkey=https://mirrors.aliyun.com/ceph/keys/release.asc
执行yum install ceph，安装完毕后Ceph –v
[root@bogon StorageMedia]# ceph -v
ceph version 13.2.10 (564bdc4ae87418a232fc901524470e1a0f76d641) mimic (stable)
查看ceph运行状态：
[root@bogon StorageMedia]# ceph -s
