1 环境
1.1 主机网络
1.1.1 系统的架构
1）节点分为控制节点、计算节点、块存储节点、对象存储节点
2）所有管理网络(10.168.0.0/24)和虚拟网络都使用私网地址连接共有网络（互联网203.0.113.x/8）
3）物理网络与虚拟网络(非10.168.0.0/24段)应当处于不同的网段
4）本架构NAT中的网关地址为10.168.0.1
5）物理节点使用NAT保持时间同步
1.1.2 部署信息
1)控制节点
hostname=rodm.cmdschool.org
ip address=10.168.0.125
OS=CentOS 6.8
2)计算节点
hostname=rod0[1-2].cmdschool.org
ip address=10.168.0.[126-127]
OS=CentOS 6.8
1.1.3 名称服务（可选）
vim /etc/hosts
输入如下信息：
10.168.0.125 rodm.cmdschool.org 10.168.0.126 rod01.cmdschool.org 10.168.0.127 rod02.cmdschool.org

3)允许非控制节点访问ntp服务
vim /etc/chrony.conf 修改同步ntp地址 allow 10.168.0.0/24
4)启动NTP服务
chkconfig chronyd on /etc/init.d/chronyd start
1.3.2 其他节点
1)yum安装chrony服务
yum install -y chrony
2）配置chrony服务
vim /etc/chrony.conf
修改如下:
#server 0.rhel.pool.ntp.org iburst #server 1.rhel.pool.ntp.org iburst #server 2.rhel.pool.ntp.org iburst #server 3.rhel.pool.ntp.org iburst server 10.168.0.125 iburst
3)启动NTP服务
centos6:
chkconfig chronyd on /etc/init.d/chronyd start
centos7:
systemctl enable chronyd.service systemctl start chronyd.service
1.3.3 验证操作
1)控制节点
chronyc sources
显示如下：
210 Number of sources = 4 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== ^- 59.46.44.253 2 8 377 159 -3305us[-3305us] +/- 66ms ^+ dns1.synet.edu.cn 2 8 377 165 -1231us[ -951us] +/- 31ms ^* time5.aliyun.com 2 8 377 160 -30us[ +250us] +/- 27ms ^+ time7.aliyun.com 2 8 377 162 +1348us[+1628us] +/- 35ms
2)其他节点
