Openstack Yogaを1から構築してみる ~Nova/Placement編~

Last updated at Posted at 2023-09-09

こんにちは。
株式会社クラスアクト インフラストラクチャ事業部の大塚です。

最近、Openstackの環境構築を1から行っていく記事を投稿しております。
詳しくは以下をご覧下さい。現在、KeystoneとGlanceをインストールし、操作できるようにしております。

今回は、Nova及びPlacementを導入していきたいと思います。

HW構成

HW 値
CPU 4sockets 4cores
Memory 40GB
Disk 100G
NIC1(ens18) 192.168.2.10
NIC2(ens19) 192.168.2.11　

用語

Novaとは？

公式サイトより引用します

NovaはOpenStackプロジェクトで、コンピュート・インスタンス（別名仮想サーバー）をプロビジョニングする方法を提供している。Novaは仮想マシンやベアメタルサーバー（ironicを使用）の作成をサポートし、システムコンテナも限定的にサポートしている。Novaは、既存のLinuxサーバーの上でデーモンのセットとして実行され、サービスを提供する。

Placementとは？

以下が分かりやすいと思います。

上記サイトから画像を引っ張ってきておりますが、スケジューラというのが、Nova schedulerの事だと思います。多分。物理的なHWリソースを管理して、Novaから「●●分のメモリ頂戴！」的な事を言われたら「ほいよ！」って感じで渡してくれるんだと思います。

NovaとPlacement用のデータベースをMariaDBに作成

4つ、新しいデータベースを作成しています。

NovaとPlacement用のユーザを作成し、ロールを編集する

以下の様にコマンドを入力し、ユーザを作成したり、adminロールに変更したりします。

NovaとPlacementをインストールし、configをいじる

以下のコマンドを実行し、必要なものをインストールします。

root@openstack:~# apt -y install nova-api nova-conductor nova-scheduler nova-novncproxy placement-api python3-novaclient

Nova、Placementそれぞれのconfigのバックアップを取得します。

root@openstack:~# cp -p /etc/nova/nova.conf /etc/nova/nova.conf.org
root@openstack:~# cp -p /etc/placement/placement.conf /etc/placement/placement.conf.org

Novaのconfigを編集していきます。
ここで少し気を付けないといけないことがあり(私の環境だけなのか)編集しなければならないはずの項目がなぜかconfigのどこを探しても無いみたいなことがありました。
例えばkeystone_authtokenで記入してねと書いているものが、私のNova環境ではありませんでした。その場合項目を追記しないいと、上手く動かなかったです。

root@openstack:~# vi /etc/nova/nova.conf
root@openstack:~# diff /etc/nova/nova.conf /etc/nova/nova.conf.org
root@openstack:~# diff /etc/nova/nova.conf /etc/nova/nova.conf.org

configの権限などを変更します。

root@openstack:~# chmod 640 /etc/nova/nova.conf
root@openstack:~# chgrp nova /etc/nova/nova.conf

NovaのDBと同期していきます。
色々出てきますが、公式サイトで無視してくださいって書いているので、とりあえず無視しました。

root@openstack:~# su -s /bin/sh -c "nova-manage api_db sync" nova

登録出来ているか確認します。公式サイトと同様に出力が出れば一旦大丈夫かと思います。

設定したconfigをNovaの各サービスに読み込ませます。

root@openstack:~# service nova-api restart
root@openstack:~# service nova-scheduler restart
root@openstack:~# service nova-conductor restart
root@openstack:~# service nova-novncproxy restart

次にPlacementの設定を編集していきます

root@openstack:~# cp -p /etc/placement/placement.conf /etc/placement/placement.conf.org
root@openstack:~# vi /etc/placement/placement.conf
root@openstack:/etc/nova# diff /etc/placement/placement.conf /etc/placement/placement.conf.org

< password = password
525,526c515
< connection = mysql+pymysql://placement:password@openstack/placement
<
---
> connection = sqlite:////var/lib/placement/placement.sqlite

configの権限等の変更を行います。

root@openstack:~# chmod 640 /etc/placement/placement.conf
root@openstack:~# chgrp placement /etc/placement/placement.conf

続いてplacement-apiのconfigを変更をしていきます。

root@openstack:~# cp -p /etc/apache2/sites-enabled/placement-api.conf /etc/apache2/sites-enabled/placement-api.conf.org
root@openstack:~# vi /etc/apache2/sites-enabled/placement-api.conf
root@openstack:~# diff /etc/apache2/sites-enabled/placement-api.conf /etc/apache2/sites-enabled/placement-api.conf.org
1c1
< Listen 127.0.0.1:8778
---
> Listen 8778

PlacementのDBと同期をしていきます

root@openstack:~# su -s /bin/sh -c "placement-manage db sync" placement

apacheのrestartを行います。

root@openstack:~# service apache2 restart

動作確認

openstack compute service listコマンドを使って出力が出るかを確認します。
出力が出れば、一旦は動いていると判断しても良いかと思います。

root@openstack:~# openstack compute service list

KVMのインストール

以下のコマンドを入力してKVMをインストールしていきます。

root@openstack:~# apt -y install qemu-kvm libvirt-daemon-system libvirt-daemon virtinst bridge-utils libosinfo-bin
root@openstack:~# apt -y install nova-compute nova-compute-kvm

Novaのconfigを編集する

root@openstack:~# vi /etc/nova/nova.conf
root@openstack:~# diff /etc/nova/nova.conf /etc/nova/nova.conf.org

nova-computeサービス起動

root@openstack:~# systemctl start nova-compute
root@openstack:~# systemctl restart nova-compute
root@openstack:~# systemctl enable nova-compute
Synchronizing state of nova-compute.service with SysV service script with /lib/systemd/systemd-sysv-install.

余談

個人的にですがなんとなく「openstackのcatalogってどういうやつなのかなぁ」みたいな疑問がありました。
以下の出力をみるとopenstack service createやopenstack endpoint createが完了して、openstackとしてサービスを提供出来るコンポーネントのリストを表示する為のコマンドなのかなぁと感じました。

root@openstack:~# openstack catalog list
