2017年2月，OpenStack Ocata版本正式release，就此记录上一版本 Newton 结合Ceph Jewel版的部署实践。宿主机操作系统为CentOS 7.2 。
初级版：
192.168.0.0/24 与 192.168.1.0/24 为Ceph使用，分别为南北向网络（Public_Network）和东西向网络（Cluster_Network）。
10.0.0.0/24 为 OpenStack 管理网络。
172.16.0.0/24 为用于 OpenStack Neutron 建立OVS bridge 用于租户业务的provider/external网络。
将它们粗暴的合并为一个网络是可以的，但在生产环境不推荐。
部署基本的 IaaS层服务核心模块：认证Keystone、镜像Glance、计算Nova、网络Neutron、块存储Cinder、Dashboard Horizon。使用 ceph-deploy部署Ceph集群，作为镜像、计算及块存储后端。
Ceph配置样例
[global]
mon_initial_members = controller, network, storage
mon_host = 192.168.0.11,192.168.0.12,192.168.0.13
auth_cluster_required = none
auth_service_required = none
auth_client_required = none
filestore_xattr_use_omap = true
osd_pool_default_size = 2
mon_clock_drift_allowed = 2
mon_clock_drift_warn_backoff = 30
mon_pg_warn_max_per_osd = 1000
public_network = 192.168.0.0/24
cluster_network = 192.168.1.0/24
3 mon+ [磁盘数] osd 使用ceph-deploy快捷部署不使用 keyring , 创建3个pool : glance , nova , cinder
根据情况调整pg_num 与pgp_num
“ 公式：
Total PGs = ((Total_number_of_OSD * 100) / max_replication_count) / pool_count
结算的结果往上取靠近2的N次方的值。比如总共OSD数量是160，复制份数3，pool数量也是3，那么按上述公式计算出的结果是1777.7。取跟它接近的2的N次方是2048，那么每个pool分配的PG数量就是2048。”
