openstack之虚拟机管理命令
2024-06-07 08:44:11
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
(nova-compute)[root@nc12 ~]# nova secgroup-list --all-tenant|grep hzb | 970a4d5f-cd19-4e1e-ab22-6355044bf79b | hzb-sg-1 | | 17b117b7731e46d6bc0f9f34d767a61b | | fdbffd7a-5f5e-413a-8d78-5f26bdc23c4e | hzb-sg | | 26a8e1feb372493d831c19d4d9e28d73 |
5）创建秘钥

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

+-------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+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, thescheduler 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 provideddestination host by the scheduler. WARNING: This couldresult in failures to actually live migrate the server tothe specified host. It is recommended to either not specifya host so that the scheduler will pick one, or specify ahost without --force. (Supported by API versions '2.30' -'2.latest')
