openstack之虚拟机管理命令
在控制节点上建hzb-openrc.sh
export OS_PROJECT_DOMAIN_ID=default export OS_USER_DOMAIN_ID=default export OS_PROJECT_NAME=hzb_tenant export OS_TENANT_NAME=hzb_tenant export OS_USERNAME=huzhengbo export OS_PASSWORD=huzhengbo export OS_AUTH_URL=http://172.16.12.7:35357/v3 export OS_IDENTITY_API_VERSION=3
source hzb-openrc.sh
以上主要是认证，使得后面创建的资源落在hzb_tenant租户上
1、创建虚拟机
1）查看一下规格
[root@cc07 ~]# nova flavor-list|grep vcpus_1 | vcpus_16_cpu_cores_8_cpu_sockets_2_ram_16384_disk_50_eph_0 | vcpus_16_cpu_cores_8_cpu_sockets_2_ram_16384_disk_50_eph_0 | 16384 | 50 | 0 | | 16 | 1.0 | True | | vcpus_16_cpu_cores_8_cpu_sockets_2_ram_32768_disk_50_eph_0 | vcpus_16_cpu_cores_8_cpu_sockets_2_ram_32768_disk_50_eph_0 | 32768 | 50 | 0 | | 16 | 1.0 | True | | vcpus_1_cpu_cores_1_cpu_sockets_1_ram_1024_disk_10_eph_0 | vcpus_1_cpu_cores_1_cpu_sockets_1_ram_1024_disk_10_eph_0 | 1024 | 10 | 0 | | 1 | 1.0 | True | | vcpus_1_cpu_cores_1_cpu_sockets_1_ram_1024_disk_1_eph_0 | vcpus_1_cpu_cores_1_cpu_sockets_1_ram_1024_disk_1_eph_0 | 1024 | 1 | 0 | | 1 | 1.0 | True |
2）查看一下镜像
[root@cc07 ~]# glance image-list|grep test-boshen
| 7dbda9ff-b13f-410b-8152-2c27c6bba4b6 | test-boshen1g |
3）查看一下网络
[root@cc07 ~]# neutron net-list --tenant-id=26a8e1feb372493d831c19d4d9e28d73 +--------------------------------------+--------------+---------------------------------------------------+ | id | name | subnets | +--------------------------------------+--------------+---------------------------------------------------+ | 0575cad8-38b0-4d0a-833c-86779f4f43bb | hzb-pub1 | | | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | hzb-privnet1 | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 10.30.0.0/24 | +--------------------------------------+--------------+---------------------------------------------------+
4）查看一下安全组

11、虚拟机卸载数据卷
nova volume-detach hzb-test 48e23242-6ce6-486f-8841-417693b5f37c
12、虚拟机挂载网卡
usage: nova interface-attach [--port-id <port_id>] [--net-id <net_id>] [--fixed-ip <fixed_ip>] <server>
[root@cc07 ~]# neutron net-list|grep hzb | 0575cad8-38b0-4d0a-833c-86779f4f43bb | hzb-pub1 | | | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | hzb-net | d0ef28a3-68fe-4b66-bb66-e723825fab82 10.23.2.0/24 | | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | hzb-privnet1 | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 10.30.0.0/24 |
[root@cc07 ~]# nova interface-attach --net-id 7856011d-32e7-42a7-887d-2f9dc3c730e7 hzb-test [root@cc07 ~]# nova list +--------------------------------------+----------+--------+------------+-------------+--------------------------------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+----------+--------+------------+-------------+--------------------------------------------+ | bf681562-161c-4d3c-8844-fed602903c6e | hzb-test | ACTIVE | - | Running | hzb-privnet1=10.30.0.65; hzb-net=10.23.2.4 | +--------------------------------------+----------+--------+------------+-------------+--------------------------------------------+
可以绑多个网卡
13、查看虚拟机的网卡信息
[root@cc07 ~]# nova interface-list hzb-test +------------+--------------------------------------+--------------------------------------+--------------+-------------------+ | Port State | Port ID | Net ID | IP addresses | MAC Addr | +------------+--------------------------------------+--------------------------------------+--------------+-------------------+ | ACTIVE | 18d5e605-d058-4f27-95db-723836d66eb5 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.33.0.66 | fa:16:3e:db:33:57 | | ACTIVE | 441965ed-bbc0-4ec8-8498-d292c5649881 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.23.2.4 | fa:16:3e:7b:6c:6a | | ACTIVE | 5f51e282-a65d-4277-8d18-e4ed3618cbef | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | 10.30.0.65 | fa:16:3e:06:40:ff | | ACTIVE | a0152728-08b5-4c95-9206-a4439ca19453 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.23.2.6 | fa:16:3e:7d:03:5b | | ACTIVE | f615713a-1551-48e1-9d0e-f250fb082607 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.23.2.5 | fa:16:3e:94:b0:4c | +------------+--------------------------------------+--------------------------------------+--------------+-------------------+
14、卸载虚拟机的网卡
usage: nova interface-detach <server> <port_id>
卸载网卡，必须指定port-id，因为同一个虚拟机的可能绑定了同一个子网的多个ip，每个ip和port是一一对应的。
[root@cc07 ~]# nova interface-detach hzb-test 441965ed-bbc0-4ec8-8498-d292c5649881 [root@cc07 ~]# nova interface-list hzb-test +------------+--------------------------------------+--------------------------------------+--------------+-------------------+ | Port State | Port ID | Net ID | IP addresses | MAC Addr | +------------+--------------------------------------+--------------------------------------+--------------+-------------------+ | ACTIVE | 18d5e605-d058-4f27-95db-723836d66eb5 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.33.0.66 | fa:16:3e:db:33:57 | | ACTIVE | 5f51e282-a65d-4277-8d18-e4ed3618cbef | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | 10.30.0.65 | fa:16:3e:06:40:ff | | ACTIVE | a0152728-08b5-4c95-9206-a4439ca19453 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.23.2.6 | fa:16:3e:7d:03:5b | | ACTIVE | f615713a-1551-48e1-9d0e-f250fb082607 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.23.2.5 | fa:16:3e:94:b0:4c | +------------+--------------------------------------+--------------------------------------+--------------+-------------------+
15、绑定浮动ip
usage: nova floating-ip-associate [--fixed-address <fixed_address>] <server> <address>
1）看有哪些可用的浮动IP
(nova-api)[root@cc07 nova]# nova floating-ip-list +--------------------------------------+---------------+-----------+----------+-----------+ | Id | IP | Server Id | Fixed IP | Pool | +--------------------------------------+---------------+-----------+----------+-----------+ | 7bb93e28-bf36-4791-aebf-94fafa27d5fa | 172.16.12.219 | - | - | vlan_1612 | | bc258041-139e-4151-98c1-a6ba7960ad59 | 172.16.12.218 | - | - | vlan_1612 | +--------------------------------------+---------------+-----------+----------+-----------+
2）将虚拟机hzb-test的10.33.0.66这个固定ip绑定到浮动IP172.16.12.218
(nova-api)[root@cc07 nova]# nova floating-ip-associate --fixed-address=10.33.0.66 hzb-test 172.16.12.218 ERROR (BadRequest): Unable to associate floating IP 172.16.12.218 to fixed IP 10.33.0.66 for instance bf681562-161c-4d3c-8844-fed602903c6e. Error: External network 519386bf-542a-4769-ac87-1b15ab96550c is not reachable from subnet d0ef28a3-68fe-4b66-bb66-e723825fab82. Therefore, cannot associate Port f615713a-1551-48e1-9d0e-f250fb082607 with a Floating IP. Neutron server returns request_ids: ['req-c59a64e0-9477-4bcc-a34b-bc5cd90fc94a'] (HTTP 400) (Request-ID: req-f28973b4-a31b-48ee-b137-806a7d6420a0)
上面报错是由于两个网段不能直接访问，可以用一个路由把他们绑定起来。
创建一个路由

将路由绑定到外部网络也就是刚才的浮动ip所在的网络
(nova-api)[root@cc07 nova]# neutron router-gateway-set f1a45281-68a1-481a-b62a-ab735c8c2e8e vlan_1612 Set gateway for router f1a45281-68a1-481a-b62a-ab735c8c2e8e (nova-api)[root@cc07 nova]# neutron router-show hzb-route-test +-------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +-------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | nova | | description | | | distributed | False | | external_gateway_info | {"network_id": "519386bf-542a-4769-ac87-1b15ab96550c", "enable_snat": true, "external_fixed_ips": [{"subnet_id": "732a6431-e412-4db6-a5ec-bd9913699bab", "ip_address": "172.16.12.235"}]} | | ha | False | | id | f1a45281-68a1-481a-b62a-ab735c8c2e8e | | name | hzb-route-test | | routes | | | rx | -1 | | status | ACTIVE | | tenant_id | 26a8e1feb372493d831c19d4d9e28d73 | | tx | -1 | +-------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
将路由绑定子网（hzb-sub-net2）也就是10.33.0.66所在的子网
(nova-api)[root@cc07 nova]# neutron router-interface-add f1a45281-68a1-481a-b62a-ab735c8c2e8e hzb-sub-net2 Added interface 3ad406ae-4c83-45d9-9d92-d1ac6d711594 to router f1a45281-68a1-481a-b62a-ab735c8c2e8e.
现在开始再次：虚拟机hzb-test的10.33.0.66这个固定ip绑定到浮动IP172.16.12.218
(nova-api)[root@cc07 nova]# nova floating-ip-associate --fixed-address=10.33.0.66 hzb-test 172.16.12.218
(nova-api)[root@cc07 nova]# nova floating-ip-list +--------------------------------------+---------------+--------------------------------------+------------+-----------+ | Id | IP | Server Id | Fixed IP | Pool | +--------------------------------------+---------------+--------------------------------------+------------+-----------+ | 7bb93e28-bf36-4791-aebf-94fafa27d5fa | 172.16.12.219 | - | - | vlan_1612 | | bc258041-139e-4151-98c1-a6ba7960ad59 | 172.16.12.218 | bf681562-161c-4d3c-8844-fed602903c6e | 10.33.0.66 | vlan_1612 | +--------------------------------------+---------------+--------------------------------------+------------+-----------+
16、解绑浮动IP
usage: nova floating-ip-disassociate <server> <address>
(nova-api)[root@cc07 nova]# nova floating-ip-disassociate hzb-test 172.16.12.218 (nova-api)[root@cc07 nova]# nova floating-ip-list +--------------------------------------+---------------+-----------+----------+-----------+ | Id | IP | Server Id | Fixed IP | Pool | +--------------------------------------+---------------+-----------+----------+-----------+ | 7bb93e28-bf36-4791-aebf-94fafa27d5fa | 172.16.12.219 | - | - | vlan_1612 | | bc258041-139e-4151-98c1-a6ba7960ad59 | 172.16.12.218 | - | - | vlan_1612 | +--------------------------------------+---------------+-----------+----------+-----------+
17、列出虚拟机的安全组
usage: nova list-secgroup <server>
(nova-api)[root@cc07 nova]# nova list-secgroup hzb-test +--------------------------------------+---------+------------------------+ | Id | Name | Description | +--------------------------------------+---------+------------------------+ | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | +--------------------------------------+---------+------------------------+
上面有4个安全组，是因为虚拟机hzb-test绑定了4个ip，每个ip默认绑定了一个default安全组
18、绑定安全组
(nova-api)[root@cc07 nova]# nova add-secgroup hzb-test boshen-sg2 (nova-api)[root@cc07 nova]# nova list-secgroup hzb-test +--------------------------------------+------------+------------------------+ | Id | Name | Description | +--------------------------------------+------------+------------------------+ | db7599e0-be38-4955-93d9-ed20f2a8a298 | boshen-sg2 | xxxxxxxxx | | db7599e0-be38-4955-93d9-ed20f2a8a298 | boshen-sg2 | xxxxxxxxx | | db7599e0-be38-4955-93d9-ed20f2a8a298 | boshen-sg2 | xxxxxxxxx | | db7599e0-be38-4955-93d9-ed20f2a8a298 | boshen-sg2 | xxxxxxxxx | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | +--------------------------------------+------------+------------------------+
上面的方法会给所有的ip都应用了安全组，boshen-sg2
如果我们只是想给具体的某一个ip应用安全组，那么只能更新具体的port
(nova-api)[root@cc07 nova]# nova list-secgroup hzb-test
+--------------------------------------+---------+------------------------+
| Id | Name | Description |
+--------------------------------------+---------+------------------------+
| 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group |
| 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group |
| 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group |
| 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group |
+--------------------------------------+---------+------------------------+
(nova-api)[root@cc07 nova]# nova interface-list hzb-test
+------------+--------------------------------------+--------------------------------------+--------------+-------------------+
| Port State | Port ID | Net ID | IP addresses | MAC Addr |
+------------+--------------------------------------+--------------------------------------+--------------+-------------------+
| ACTIVE | 18d5e605-d058-4f27-95db-723836d66eb5 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.33.0.66 | fa:16:3e:db:33:57 |
| ACTIVE | 5f51e282-a65d-4277-8d18-e4ed3618cbef | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | 10.30.0.65 | fa:16:3e:06:40:ff |
| ACTIVE | a0152728-08b5-4c95-9206-a4439ca19453 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.23.2.6 | fa:16:3e:7d:03:5b |
| ACTIVE | f615713a-1551-48e1-9d0e-f250fb082607 | 7856011d-32e7-42a7-887d-2f9dc3c730e7 | 10.23.2.5 | fa:16:3e:94:b0:4c |
+------------+--------------------------------------+--------------------------------------+--------------+-------------------+
现在我们将安全组boshen-sg2应用到10.23.2.5这个port上
(nova-api)[root@cc07 nova]# neutron port-update --security-group=boshen-sg2 f615713a-1551-48e1-9d0e-f250fb082607 Updated port: f615713a-1551-48e1-9d0e-f250fb082607 (nova-api)[root@cc07 nova]# nova list-secgroup hzb-test +--------------------------------------+------------+------------------------+ | Id | Name | Description | +--------------------------------------+------------+------------------------+ | db7599e0-be38-4955-93d9-ed20f2a8a298 | boshen-sg2 | xxxxxxxxx | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | +--------------------------------------+------------+------------------------+
19、卸载安全组
(nova-api)[root@cc07 nova]# nova remove-secgroup hzb-test boshen-sg2 (nova-api)[root@cc07 nova]# nova list-secgroup hzb-test +--------------------------------------+---------+------------------------+ | Id | Name | Description | +--------------------------------------+---------+------------------------+ | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | | 6a5dd6bb-600f-49bb-b37b-91059ff4074b | default | Default security group | +--------------------------------------+---------+------------------------+
上面的方法会给所有的ip都卸载了安全组，boshen-sg2
20、查看vnc
(nova-api)[root@cc07 nova]# nova get-vnc-console hzb-test novnc +-------+----------------------------------------------------------------------------------+ | Type | Url | +-------+----------------------------------------------------------------------------------+ | novnc | http://172.16.12.7:6080/vnc_auto.html?token=cf81ba3f-3103-4f49-9b9c-85a910f74848 | +-------+----------------------------------------------------------------------------------+
21、resize（通过设置不同的flavor实现的）
nova resize hzb-test vcpus_1_cpu_cores_1_cpu_sockets_1_ram_2048_disk_60_eph_0
22、lock/unlock
lock后，可以防止对其进行其他误操作
nova lock hzb-test nova unlock hzb-test
23、创建快照
其工作原理是对 instance的镜像文件（系统盘）进行全量备份，生成一个类型为 snapshot的 image，然后将其保存到 Glance上。快照之前，最好先pause虚拟机
nova create-image hzb-test hzb-test-snapshot
24、重建
nova rebuild hzb-test-snapshot
25、shelve/unshelve
1）、shelve 将 instance 保存到 Glance 上，之后可通过 Unshelve 重新部署。 Shelve 操作成功后，instance 会从原来的计算节点上删除。
[root@cc07 ~]# nova shelve h001 [root@cc07 ~]# nova list +--------------------------------------+------+--------+-------------------------------+-------------+-------------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+------+--------+-------------------------------+-------------+-------------------------+ | 4c46b8fd-dfff-4971-83c7-6ac8e46b99e9 | h001 | ACTIVE | shelving_image_pending_upload | Running | hzb-privnet1=10.30.0.66 | +--------------------------------------+------+--------+-------------------------------+-------------+-------------------------+
[root@cc07 ~]# glance image-list|grep h001 | 32e9c33f-ae53-4ff2-9885-1f3909a7b094 | h001-shelved |
会自动生成镜像h001-shelved
2）unshelve， 会重新选择节点部署，可能不是原节点。
usage: nova unshelve <server>
26，migrate/live-migration
1)、migrate，将 instance 迁移到其他计算节点。 迁移之前，instance 会被 Shut Off，支持共享存储和非共享存储。不支持指定迁移到哪个计算节点
usage: nova migrate [--poll] <server> Migrate a server. The new host will be selected by the scheduler. Positional arguments: <server> Name or ID of server. Optional arguments: --poll Report the server migration progress until it completes.
nova migrate cc64cd70-a4d2-4850-aec9-dd9147866956
2）live-migration，能不停机在线地迁移 instance，保证了业务的连续性。也支持共享存储和非共享存储（Block Migration）
usage: nova live-migration [--block-migrate] [--force] <server> [<host>] Migrate running server to a new machine. Positional arguments: <server> Name or ID of server. <host> Destination host name. If no host is specified, the scheduler will choose one. Optional arguments: --block-migrate True in case of block_migration. (Default=auto:live_migration) (Supported by API versions '2.25' - '2.latest') --force Force a live-migration by not verifying the provided destination host by the scheduler. WARNING: This could result in failures to actually live migrate the server to the specified host. It is recommended to either not specify a host so that the scheduler will pick one, or specify a host without --force. (Supported by API versions '2.30' - '2.latest')
