openstack之虚拟机管理命令
生活随笔
收集整理的這篇文章主要介紹了
openstack之虚拟机管理命令
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
在控制節點上建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以上主要是認證，使得后面創建的資源落在hzb_tenant租戶上
1、創建虛擬機
?1）查看一下規格
[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）查看一下鏡像
[root@cc07 ~]# glance image-list|grep test-boshen | 7dbda9ff-b13f-410b-8152-2c27c6bba4b6 | test-boshen1g |3）查看一下網絡

(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 | +-------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+將路由綁定子網（hzb-sub-net2）也就是10.33.0.66所在的子網
(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.現在開始再次：虛擬機hzb-test的10.33.0.66這個固定ip綁定到浮動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、解綁浮動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、列出虛擬機的安全組
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個安全組，是因為虛擬機hzb-test綁定了4個ip，每個ip默認綁定了一個default安全組
18、綁定安全組
(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 | +--------------------------------------+------------+------------------------+上面的方法會給所有的ip都應用了安全組，boshen-sg2
如果我們只是想給具體的某一個ip應用安全組，那么只能更新具體的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 | +------------+--------------------------------------+--------------------------------------+--------------+-------------------+現在我們將安全組boshen-sg2應用到10.23.2.5這個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、卸載安全組
(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 | +--------------------------------------+---------+------------------------+上面的方法會給所有的ip都卸載了安全組，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（通過設置不同的flavor實現的）
nova resize hzb-test vcpus_1_cpu_cores_1_cpu_sockets_1_ram_2048_disk_60_eph_022、lock/unlock
lock后，可以防止對其進行其他誤操作
nova lock hzb-test nova unlock hzb-test23、創建快照
其工作原理是對 instance的鏡像文件（系統盤）進行全量備份，生成一個類型為 snapshot的 image，然后將其保存到 Glance上。快照之前，最好先pause虛擬機
nova create-image hzb-test hzb-test-snapshot24、重建
nova rebuild hzb-test-snapshot25、shelve/unshelve
1）、shelve 將 instance 保存到 Glance 上，之后可通過 Unshelve 重新部署。 Shelve 操作成功后，instance 會從原來的計算節點上刪除。
[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 |會自動生成鏡像h001-shelved
2）unshelve，?會重新選擇節點部署，可能不是原節點。
usage: nova unshelve <server>?26，migrate/live-migration
1)、migrate，將 instance 遷移到其他計算節點。 遷移之前，instance 會被 Shut Off，支持共享存儲和非共享存儲。不支持指定遷移到哪個計算節點
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-dd91478669562）live-migration，能不停機在線地遷移 instance，保證了業務的連續性。也支持共享存儲和非共享存儲（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') nova live-migration cc64cd70-a4d2-4850-aec9-dd9147866956 compute.chinacloud.com?
