Nutanix ₊ OpenStack を Controller と Acropolice Driver ノードを別サーバとして構成してみました。今回は、Nova / Neutron / Cinder / Glance のサービスが実際に使用できることを確認します。
前回構成した環境を OS ごと再起動して、下記のような状態にしてあります。
OVM#1（Acropolis Driver-Only Mode）

OVM#2（OpenStack Controller）
[root@ovm02 ~]# openstack-status == Nova services == openstack-nova-api: active openstack-nova-cert: active openstack-nova-compute: inactive (disabled on boot) openstack-nova-network: inactive (disabled on boot) openstack-nova-scheduler: active openstack-nova-conductor: active == Glance services == openstack-glance-api: inactive (disabled on boot) openstack-glance-registry: inactive (disabled on boot) == Keystone service == openstack-keystone: active == Horizon service == openstack-dashboard: active == neutron services == neutron-server: active neutron-dhcp-agent: inactive (disabled on boot) neutron-l3-agent: inactive (disabled on boot) neutron-metadata-agent: inactive (disabled on boot) neutron-openvswitch-agent: inactive (disabled on boot) == Swift services == openstack-swift-proxy: active openstack-swift-account: active openstack-swift-container: active openstack-swift-object: active == Cinder services == openstack-cinder-api: active openstack-cinder-scheduler: active openstack-cinder-volume: inactive (disabled on boot) openstack-cinder-backup: active == Ceilometer services == openstack-ceilometer-api: active openstack-ceilometer-central: active openstack-ceilometer-compute: inactive (disabled on boot) openstack-ceilometer-collector: active openstack-ceilometer-alarm-notifier: active openstack-ceilometer-alarm-evaluator: active openstack-ceilometer-notification: active == Heat services == openstack-heat-api: active openstack-heat-api-cfn: inactive (disabled on boot) openstack-heat-api-cloudwatch: inactive (disabled on boot) openstack-heat-engine: active == Sahara services == openstack-sahara-api: inactive (disabled on boot) == Trove services == openstack-trove-api: active openstack-trove-taskmanager: active openstack-trove-conductor: active == Support services == mysqld: active (disabled on boot) openvswitch: inactive (disabled on boot) dbus: active rabbitmq-server: active memcached: active == Keystone users == Warning keystonerc not sourced
今回は CLI から操作してみます。そして Nutanix の Prism UI でも結果を確認してみます。
環境変数の読み込み
/root/keystonerc_admin ファイルです。
[root@ovm02 ~]# cat keystonerc_admin unset OS_SERVICE_TOKEN export OS_USERNAME=admin export OS_PASSWORD=admin export OS_AUTH_URL=http://127.0.0.1:5000/v2.0 export PS1='[\u@\h \W(keystone_admin)]\$ ' export OS_TENANT_NAME=admin export OS_REGION_NAME=RegionOne
せっかくなので、OS_AUTH_URL を Controller である OVM#2 のアドレスにしておきます。
[root@ovm02 ~]# source keystonerc_admin [root@ovm02 ~(keystone_admin)]# export OS_AUTH_URL=http://ovm02.ntnx.local:5000/v2.0
Image サービス （Glance）
QCAW2 の OS イメージを登録してみます。今回は、Oracle Linux 6.6 の OpenStack 用イメージを ol66 という名前で登録しています。
[root@ovm02 ~(keystone_admin)]# glance image-create --name=ol66 \ > --file=OracleLinux-6.6-x86_64.qcow2 \ > --container-format=bare \ > --disk-format=qcow2 \ > --is-public=true +------------------+--------------------------------------+ | Property | Value | +------------------+--------------------------------------+ | checksum | 0 | | container_format | bare | | created_at | 2016-04-18T17:30:03.000000 | | deleted | False | | deleted_at | None | | disk_format | qcow2 | | id | 8061cbc8-fc49-4ae5-bd40-5f008fec8808 | | is_public | True | | min_disk | 0 | | min_ram | 0 | | name | ol66 | | owner | 529638a186034e5daa11dd831cd1c863 | | protected | False | | size | 370281984 | | status | active | | updated_at | 2016-04-18T17:33:55.000000 | | virtual_size | None | +------------------+--------------------------------------+
Prism でも Image Configuration からイメージが確認できます。
Glance で指定した名前で登録されます。
Netork サービス（Neutron）
ネットワークを「net01」という名前で作成してみます。
[root@ovm02 ~(keystone_admin)]# neutron net-create net01 --shared Created a new network: +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | admin_state_up | True | | id | dcb04863-99e1-4641-8945-9e126dfa294e | | mtu | 0 | | name | net01 | | provider:network_type | vlan | | provider:physical_network | default | | provider:segmentation_id | 18 | | router:external | False | | shared | True | | status | ACTIVE | | subnets | | | tenant_id | 529638a186034e5daa11dd831cd1c863 | +---------------------------+--------------------------------------+
「net01」に、サブネット「subnet01」を作成します。
エラーを避けるため、Gateway と DNS サーバのアドレスも指定します。
[root@ovm02 ~(keystone_admin)]# neutron subnet-create dcb04863-99e1-4641-8945-9e126dfa294e 192.168.10.0/24 \
> --name subnet01 \
> --enable_dhcp \
> --allocation-pool start=192.168.10.11,end=192.168.10.20 \
> --gateway=192.168.10.1 \
> --dns-nameserver=192.168.10.1
Created a new subnet:
+-------------------+----------------------------------------------------+

+-------------------+----------------------------------------------------+
| allocation_pools | {"start": "192.168.10.11", "end": "192.168.10.20"} |

| tenant_id | 529638a186034e5daa11dd831cd1c863 |
+-------------------+----------------------------------------------------+
Prism から確認でも、ネットワークが追加されたことが確認できます。
ネットワーク名は空欄で、VLAN ID は自動採番です。
ネットワークアドレス、デフォルトゲートウェイ、DNS サーバのアドレスが設定されています。
IP アドレスプールも自動的に登録されます。
DHCP サーバの IP アドレスは、ネットワークアドレスの末尾になっています。
Volume サービス（Cinder）
「vol01」という名前で、1GB のボリュームを作成します。
[root@ovm02 ~(keystone_admin)]# cinder create --display-name vol01 1
+---------------------+--------------------------------------+
| Property | Value |
+---------------------+--------------------------------------+
| attachments | [] |
| availability_zone | nova |
| bootable | false |
| created_at | 2016-04-18T17:44:51.310726 |
| display_description | None |
| display_name | vol01 |

| id | f8a7392f-6034-4518-bce1-001d68978a74 |

| multiattach | false |
| size | 1 |
| snapshot_id | None |
| source_volid | None |

| volume_type | None |
+---------------------+--------------------------------------+
Prism で、指定どおり 1GB のボリュームグループとして作成されていることがわかります。Cinder で指定した名前がそのまま使用されています。
Compute サービス（Nova）
Nova でインスタンス「vm01」を起動します。
これまで作成した Glance イメージ、Neutron ネットワークを指定します。
[root@ovm02 ~(keystone_admin)]# nova boot --flavor=1 --image=ol66 \

+--------------------------------------+---------------------------------------------+
インスタンスが起動したら、作成した Cinder ボリュームを接続します。
[root@ovm02 ~(keystone_admin)]# nova volume-attach vm01 f8a7392f-6034-4518-bce1-001d68978a74 +----------+--------------------------------------+ | Property | Value | +----------+--------------------------------------+ | device | /dev/sdb | | id | f8a7392f-6034-4518-bce1-001d68978a74 | | serverId | 497dc42b-f11b-4303-9ddd-d508fc2fa55d | | volumeId | f8a7392f-6034-4518-bce1-001d68978a74 | +----------+--------------------------------------+
Prism でも、neutron / cinder で作成したネットワークとボリュームに接続されたことが確認できます。
以上。
