三个节点ip信息
controller:192.168.100.10
network:192.168.100.20
compute1:192.168.100.30
修改各节点的/etc/hosts 文件
测试各节点到openstack.org的连通性
controller node
配置NTP服务
yum install -y ntp
vi /etc/ntp.conf 修改文件如下：

restrict -4 default kod notrap nomodify
restrict -6 default kod notrap nomodify
systemctl enable ntpd.service #开机启动
systemctl start ntpd.service
其他节点同样安装
yum install ntp
修改/etc/ntp.conf文件如下：
server controller iburst
开机启动服务：
systemctl enable ntpd.service
systemctl start ntpd.service
