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。

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。

Openstack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。

Openstack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。

Openstack创建虚拟机1

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。

Openstack创建虚拟机2

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)。

Openstack创建虚拟机3

如下创建秘钥对:

Openstack创建虚拟机4

点击 网络 选项卡,点击网络框中的+为虚拟机选择私有网络。

Openstack创建虚拟机5

以上设置完成后点击运行,开始创建虚拟机。

Openstack创建虚拟机6

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。

Openstack创建虚拟机7

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。

Openstack访问 & 安全1

然后点击添加规则。

Openstack访问 & 安全2

如下添加ICMP规则,允许虚拟机被ping通。

Openstack访问 & 安全3

添加SSH规则,允许虚拟机通过SSH客户端进行连接。

Openstack访问 & 安全4

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)。

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。

Openstack云硬盘1

然后点击更多,选择 编辑挂载。

Openstack云硬盘2

选择要连接到的虚拟机,然后连接数据盘。

Openstack云硬盘3

登陆虚拟机,对已挂在的数据盘进行分区。

Openstack云硬盘4

Openstack云硬盘5

格式化数据盘并挂载。

Openstack云硬盘6

将需要挂载的数据盘 写入/etc/fstab文件,以便开机自动挂载。
