Openstack 使用
OpenStack作为基础设施即服务（简称IaaS）资源的通用前端。首要任务是简化云的部署过程并为其带来良好的可扩展性。本文希望通过提供必要的指导信息，帮助大家利用OpenStack前端来设置及管理自己的私有云。openstack导入虚拟机镜像
如下列出了一下虚拟机镜像，可以在本地下载后通过Openstack界面导入。 https://openstack.redhat.com/Image_resources 也可以参考如下文档自己制作镜像： https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/OpenStack/page/Creating%20qcow2%20CentOS%20Image%20for%20OpenStack 导入镜像：点击左侧的镜像 选项卡，可以看到已经导入的镜像，点击创建镜像 按钮创建镜像。
填写 镜像名称，镜像源选择—镜像文件，格式选择 QCOW2，勾选 公有 框（这样你上传得镜像其他人也能使用），然后点击创建镜像。
创建虚拟机
点击左侧的 实例 选项卡，可以看到已创建的虚拟机，点击右上角的启动云主机创建 虚拟机。
在详情选项卡填写云主机名称、选择云主机的规格类型、云主机数量、云主机启动的源，本文从镜像启动，然后选择镜像名称，点击 访问 & 安全选项卡。
选择一个秘钥对，如果没有需要点击加按钮进行创建，此秘钥对用于登陆创建的虚拟主机（在Openstack中虚拟主机的登陆一般不是通过用户名密码登陆的）。安全组选择default（用于设置防火墙规则）。
如下创建秘钥对：
点击 网络 选项卡，点击网络框中的+为虚拟机选择私有网络。
以上设置完成后点击运行，开始创建虚拟机。
点击更多，分配浮动IP地址，虚拟机只能通过浮动IP地址进行登陆。
访问 & 安全
默认情况下，创建的虚拟机不能被ping 通和进行ssh 连接，需要修改默认安全规则。点击 管理规则。
然后点击添加规则。
如下添加ICMP规则，允许虚拟机被ping通。
添加SSH规则，允许虚拟机通过SSH客户端进行连接。
分配完浮动IP地址并设置好安全规则就可以登陆虚拟机了（必须在生成ssh key的机器上进行登陆）。
[root@fuel ~]# ssh centos@172.16.200.133 [centos@vm-centos-7 ~]$ sudo su - [root@vm-centos-7 ~]#
为虚拟机挂载数据盘
点击 左侧的 云硬盘 选项卡，点击 创建云硬盘 按钮，然后如下填写 创建云硬盘。
然后点击更多，选择 编辑挂载。
选择要连接到的虚拟机，然后连接数据盘。
登陆虚拟机，对已挂在的数据盘进行分区。
格式化数据盘并挂载。
将需要挂载的数据盘 写入/etc/fstab文件，以便开机自动挂载。
