openstack中某个实例新增加一个网卡有两种方式 一种是用通过openstack增加 这种增加不但会增加一个虚拟网卡，还会自动分配一个ip ##设置环境变量 source .admin_openrc.sh ##查看网络 neutron net-list neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. +--------------------------------------+-------------+----------------------------------+------------------------------------------------------+ | id | name | tenant_id | subnets | +--------------------------------------+-------------+----------------------------------+------------------------------------------------------+ | 763b1b5b-85d7-4101-a51b-d621931d15b8 | selfservice | 6f4b66aa95e84d7191d989a940830a95 | 936bc613-2c2c-447e-9936-137e3cd182fc 172.16.1.0/24 | | e035ec48-c7b7-414b-bc0c-117f0900e915 | provider | 6f4b66aa95e84d7191d989a940830a95 | 3bc9c2bf-d4ed-4e61-88d5-2be2b4cc073e 192.168.96.0/21 | +--------------------------------------+-------------+----------------------------------+------------------------------------------------------+ ##增加网络端口 neutron port-create 763b1b5b-85d7-4101-a51b-d621931d15b8 ###可以指定ip哦 +-----------------------+-----------------------------------------------------------------------------------+ | Field | Value | +-----------------------+-----------------------------------------------------------------------------------+ | admin_state_up | True | | allowed_address_pairs | | | binding:host_id | compute | | binding:profile | {} | | binding:vif_details | {"port_filter": true} | | binding:vif_type | bridge | | binding:vnic_type | normal | | created_at | 2018-07-13T03:09:54Z | | description | | | device_id | 706d5c3b-0511-4bbf-b101-e1780c893b79 | | device_owner | compute:nova | | extra_dhcp_opts | | | fixed_ips | {"subnet_id": "936bc613-2c2c-447e-9936-137e3cd182fc", "ip_address": "172.16.1.7"} | | id | 4dfaaf48-0fd0-4a9d-82eb-a2190c5b8ff4 | | mac_address | fa:16:3e:f4:50:fb | | name | | | network_id | 763b1b5b-85d7-4101-a51b-d621931d15b8 | | port_security_enabled | True | | project_id | 6f4b66aa95e84d7191d989a940830a95 | | revision_number | 7 | | security_groups | 48747bda-428d-423e-8a9f-b34d8c9318f8 | | status | ACTIVE | | tags | | | tenant_id | 6f4b66aa95e84d7191d989a940830a95 | | updated_at | 2018-07-13T03:15:09Z | +-----------------------+-----------------------------------------------------------------------------------+ ##查看看实例 nova list --all +--------------------------------------+-----------+----------------------------------+--------+------------+-------------+-------------------------+ | ID | Name | Tenant ID | Status | Task State | Power State | Networks | +--------------------------------------+-----------+----------------------------------+--------+------------+-------------+-------------------------+ | 1af14a6b-21e5-446c-b73e-0c1d73c293cb | 2 | 6f4b66aa95e84d7191d989a940830a95 | ACTIVE | -
