1. 配置yum源
cat <<END >/etc/yum.repos.d/ceph.repo
[Ceph]
name=Ceph packages for $basearch
baseurl=http://mirrors.aliyun.com/ceph/rpm-luminous/el7/$basearch
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc

[Ceph-noarch]
name=Ceph noarch packages
baseurl=http://mirrors.aliyun.com/ceph/rpm-luminous/el7/noarch
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc

[ceph-source]
name=Ceph source packages
baseurl=http://mirrors.aliyun.com/ceph/rpm-luminous/el7/SRPMS
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc
END
  1. 安装yum相关依赖 yum -y install yum-plugin-priorities yum install -y yum-utils snappy leveldb gdiskpython-argparse gperftools-libs ntpdate yum install ceph-deploy
  2. 创建目录作为部署目录，存放key密钥，日志等 cd mkdir ceph
  3. ceph软件包安装 ceph-deploy install –no-adjust-repos ceph-03
  4. 创建ceph集群 ceph-deploy new –cluster-network 10.57.26.0/24 ceph-03
  5. 修改ceph.conf，添加参数
[global]
fsid = 56c894f9-3173-476f-bbd0-169d0c0e86eb
cluster_network = 10.57.26.0/24
mon_initial_members = ceph-03
mon_host = 10.57.26.32
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
#添加一下参数
osd_pool_default_size = 1
rbd_default_features = 1
  1. 创建monitor ceph-deploy mon create ceph-03
  2. 为节点准备key ceph-deploy gatherkeys ceph-03
  3. 创建osd ceph-deploy osd prepare ceph-03:/dev/vdb
  4. 激活osd ceph-deploy osd activate ceph-03:/dev/vdb
  5. 允许一主机以管理员权限执行 Ceph 命令 ceph-deploy admin ceph-03
  6. 把改过的配置文件分发给集群内各主机 ceph-deploy –overwrite-conf config push ceph-03
  7. 创建监控 ceph-deploy mgr create ceph-03
  8. 查看mgr状态 netstat -tunlp|grep 7000
  9. 开启dashboard ceph mgr module enable dashboard
