OpenStack是一个由NASA（美国国家航空航天局）和Rackspace合作研发并发起的，以Apache许可证授权的自由软件和开放源代码项目。
OpenStack是一个开源的云计算管理平台项目，由几个主要的组件组合起来完成具体工作。OpenStack支持几乎所有类型的云环境，项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。OpenStack通过各种互补的服务提供了基础设施即服务（IaaS）的解决方案，每个服务提供API以进行集成。

在openstack-node1上配置：（centos7用chrony，centos6用ntp）
# 安装chrony [root@openstack-node1 ~]#yum install -y chrony # 配置chrony [root@openstack-node1 ~]#vi /etc/chrony.conf # 允许哪些服务器和自己同步 allow 172.30/16 # 设置服务开机启动 [root@openstack-node1 ~]#systemctl enable chronyd.service [root@openstack-node1 ~]#systemctl start chronyd.service [root@openstack-node1 ~]#timedatectl set-timezone Asia/Shanghai [root@openstack-node1 ~]#timedatectl status
在openstack-node2上配置：

MQ 全称 Message Queue，消息队列（MQ）是一种应用程序对应用程序的通信方法。应用程序通过读写出入队列的消息（针对应用程序的数据）来通信，而无需专用连接来链接它们。消息传递指的是程序之间通过在消息中发送数据进行通信，而不是通过直接调用彼此来通信，直接调用通常是用于诸如远程过程调用的技术。排队指的是应用程序通过队列来通信。队列的使用出去了接收和发送应用程序同时执行的要求。RabbitMQ是一个在AMQP基础上完整的，可复用的企业消息系统。他遵循Mozilla Public License开源协议。

访问rabbitMQ，访问地址http://172.30.10.9:15672 默认用户名密码都是guest
1.点击Admin，创建openstack用户密码
2.点击用户名openstack，在“Update this user”菜单中输入密码及标签（administrator）
3.登出当前用户，使用openstack登录，测试是否创建成功
