1 使用OpenStack CLI
1.1 配置OpenStack CLI的环境变量
步骤一：source /opt/stack/nova/tools/nova-manage.bash_completion
步骤二：source /opt/devstack/openrc admin admin，其中第一个admin代表租户，第二个admin代表用户；也可以使用demo demo来执行上述命令。
stack@henry-desktop:/opt/devstack$ source /opt/stack/nova/tools/nova-manage.bash_completion
stack@henry-desktop:/opt/devstack$ ls -l openrc
-rw-r--r-- 1 stack stack 4033 5月 1 23:16 openrc
stack@henry-desktop:/opt/devstack$ source openrc admin admin
WARNING: setting legacy OS_TENANT_NAME to support cli tools.

[--return-reservation-id]
Boot a new server.
Positional arguments:
Name for the new server.
Optional arguments:
--flavor Name or ID of flavor (see 'nova flavor-list').
--image Name or ID of image (see 'glance image-list').
--image-with Image metadata property (see 'glance image-
show').
--boot-volume Volume ID to boot from.
--snapshot Snapshot ID to boot from (will create a
volume).
--min-count Boot at least servers (limited by
quota).
--max-count Boot up to servers (limited by
quota).
--meta Record arbitrary key/value metadata to
/meta_data.json on the metadata server. Can be
specified multiple times.
--key-name Key name of keypair that should be created
earlier with the command keypair-add.
--user-data user data file to pass to be exposed by the
metadata server.
--availability-zone
The availability zone for server placement.
--security-groups
Comma separated list of security group names.
--block-device-mapping
Block device mapping in the format =:::.
--block-device key1=value1[,key2=value2...]
Block device mapping with the keys: id=UUID
(image_id, snapshot_id or volume_id only if
using source image, snapshot or volume)
source=source type (image, snapshot, volume or
blank), dest=destination type of the block
device (volume or local), bus=device's bus
(e.g. uml, lxc, virtio, ...; if omitted,
hypervisor driver chooses a suitable default,
honoured only if device type is supplied)
type=device type (e.g. disk, cdrom, ...;
defaults to 'disk') device=name of the device
(e.g. vda, xda, ...; if omitted, hypervisor
driver chooses suitable device depending on
selected bus; note the libvirt driver always
uses default device names), size=size of the
block device in MB(for swap) and in GiB(for
other formats) (if omitted, hypervisor driver
calculates size), format=device will be
formatted (e.g. swap, ntfs, ...; optional),
bootindex=integer used for ordering the boot
disks (for image backed instances it is equal
to 0, for others need to be specified),
shutdown=shutdown behaviour (either preserve
or remove, for local destination set to
remove) and tag=device metadata tag
(optional). (Supported by API versions '2.42'
- '2.latest')
--swap Create and attach a local swap block device of
MB.
--ephemeral size=[,format=]
Create and attach a local ephemeral block
device of GiB and format it to
.
--hint Send arbitrary key/value pairs to the
scheduler for custom use.
--nic
Create a NIC on the server. Specify option
multiple times to create multiple nics unless
using the special 'auto' or 'none' values.
auto: automatically allocate network resources
if none are available. This cannot be
specified with any other nic value and cannot
be specified multiple times. none: do not
attach a NIC at all. This cannot be specified
with any other nic value and cannot be
specified multiple times. net-id: attach NIC
to network with a specific UUID. net-name:
attach NIC to network with this name (either
port-id or net-id or net-name must be
provided), v4-fixed-ip: IPv4 fixed address for
NIC (optional), v6-fixed-ip: IPv6 fixed
address for NIC (optional), port-id: attach
NIC to port with this UUID tag: interface
metadata tag (optional) (either port-id or
net-id must be provided). (Supported by API
versions '2.42' - '2.latest')
--config-drive Enable config drive.
--poll Report the new server boot progress until it
completes.
--admin-pass Admin password for the instance.
--access-ip-v4 Alternative access IPv4 of the instance.
--access-ip-v6 Alternative access IPv6 of the instance.
--description Description for the server. (Supported by API
versions '2.19' - '2.latest')
--tags Tags for the server.Tags must be separated by
commas: --tags (Supported by API
versions '2.52' - '2.latest')
--return-reservation-id Return a reservation id bound to created
servers.
