人生三从境界:昨夜西风凋碧树,独上高楼,望尽天涯路。 衣带渐宽终不悔,为伊消得人憔悴。 众里寻他千百度,蓦然回首,那人却在灯火阑珊处。

Nova组件概述

一、Nova组件概述

计算节点通过Nova Computer进行虚拟机创建,通过libvirt调用kvm创建虚拟机,nova之间通信通过rabbitMQ队列进行通信。
Nova位于Openstack架构的中心,其他服务或者组件(比如Glance、Cinder、Neutron等)对它提供支持,另外它本身的架构也比较复杂。

作用:

  1. Nova是OpenStack最核心的服务模块,负责管理和维护云计算环境的计算资源,负责整个云环境虚拟机生命周期的管理。
  2. Nova是OpenStack的计算服务,负责维护和管理的网络和存储,提供计算服务。

三、nova和其他组件交互操作

1、云主机卷挂载操作

nova
    volume-attach               Attach a volume to a server.                 # 卷挂载到云主机
    volume-attachments          List all the volumes attached to a server.   # 查看所有挂载到云主机上的卷
    volume-detach               Detach a volume from a server.               # 卷从云主机上卸载
    volume-update               Update volume attachment.                    # 卷挂载状态更新

# 卷挂载到云主机
nova volume-attach <server> <volume> [<device>]
    Positional arguments:
    <server>  Name or ID of server.
    <volume>  ID of the volume to attach.
    <device>  Name of the device e.g. /dev/vdb. Use "auto" for autoassign (if
                supported). Libvirt driver will use default device name.

[root@controller cinder]# nova volume-attach test111 f594e936-05e2-4a8c-b4c9-b96bbe7e2c82 /dev/vdb
+----------+--------------------------------------+
| Property | Value                                |
+----------+--------------------------------------+
| device   | /dev/vdb                             |
| id       | f594e936-05e2-4a8c-b4c9-b96bbe7e2c82 |
| serverId | 4b3a90f0-4177-44cc-8ef2-34a0e5d56b33 |
| volumeId | f594e936-05e2-4a8c-b4c9-b96bbe7e2c82 |
+----------+--------------------------------------+

# 查看所有挂载到云主机上的卷
[root@controller cinder]# nova  volume-attachments test111
+--------------------------------------+----------+--------------------------------------+--------------------------------------+
| ID                                   | DEVICE   | SERVER ID                            | VOLUME ID                            |
+--------------------------------------+----------+--------------------------------------+--------------------------------------+
| f594e936-05e2-4a8c-b4c9-b96bbe7e2c82 | /dev/vdb | 4b3a90f0-4177-44cc-8ef2-34a0e5d56b33 | f594e936-05e2-4a8c-b4c9-b96bbe7e2c82 |
+--------------------------------------+----------+--------------------------------------+--------------------------------------+

# 卷从云主机上卸载
nova volume-detach <server> <volume>
    Positional arguments:
    <server>  Name or ID of server.
    <volume>  ID of the volume to detach.

[root@controller cinder]# nova  volume-detach test111 f594e936-05e2-4a8c-b4c9-b96bbe7e2c82
[root@controller cinder]# nova  volume-attachments test111
