系统部署环境
系统配置
OpenStack部署平台包含4个计算节点，系统配置如下表所示。 序号 1 IP 192.168.100.81 101.101.101.81 192.168.100.82 101.101.101.82 192.168.100.83 101.101.101.83 192.168.100.84 101.101.101.84 主机名 CPU 2*8Core 2.4GHz Intel(R) Xeon(R) CPU E5-2630 2*8Core 2.4GHz Intel(R) Xeon(R) CPU E5-2630 2*8Core 2.4GHz Intel(R) Xeon(R) CPU E5-2630 2*8Core 2.4GHz Intel(R) Xeon(R) CPU E5-2630 内存 磁盘 操作系统 CentOS Linux release 7.2.1511 CentOS Linux release 7.2.1511 CentOS Linux release 7.2.1511 CentOS Linux release 7.2.1511 Controller 64GB 1.7TB 2 Computer01 64GB 1.7TB 3 Computer02 64GB 1.7TB 4 Computer03 64GB 1.7TB 其中，我们选取Controller节点作为OpenStack的管理节点和Ceph的部署节点，选取Computer01~Computer03作为计算节点。所有节点部署Ceph OSD
OpenStack安装版本为Mitaka
安装参考：http://docs.openstack.org/mitaka/install-guide-rdo/
http://docs.openstack.org/mitaka/zh_CN/install-guide-rdo/index.html。
Ceph安装版本为Jewel
安装参考：http://docs.ceph.com/docs/master/start/
两者集成参考：http://docs.ceph.com/docs/master/rbd/rbd-openstack/。
网络配置
本部署采用self-service网络架构。
基本配置 时间同步
安装NTP（Network Time Protocol）协议实现软件Chrony，保证管理节点与计算节点之间的时间同步。
A. 管理节点Controller上执行以下操作：
4
安装chrony组件 # yum install chrony 修改配置文件
#vim /etc/chrony.conf
修改时钟服务器
server 0.centos.pool.ntp.org iburst server 1.centos.pool.ntp.org iburst server 2.centos.pool.ntp.org iburst server 3.centos.pool.ntp.org iburst
追加子网段，允许其他节点可以连接到Controller的chrony daemon allow 192.168.100.0/24
开机自启动并启动NTP服务 # systemctl enable chronyd.service #systemctl restart chronyd.service
B. 其他节点执行以下操作 安装chrony组件 # yum install chrony
修改配置文件
# vim /etc/chrony.conf
修改时钟服务器为Controller server Controller iburst
开机自启动并启动NTP服务 # systemctl enable chronyd.service # systemctl start chronyd.service
C. 验证时间同步服务
在Controller节点上验证NTP服务 # chronyc sources
在其他节点上验证NTP服务 # chronyc sources
