Azure コラム 第4回 「Azure Resource ManagerによるWebアプリケーション環境の展開~IaaS~」


さて第3回までは座談と言う感じで進んできましたが、ここらでお隣のWindows10コラムにも倣って実際の画面などお見せしつつ、何回かに分けて実践のご紹介をしていこうかと思います。
今回は入門編、「Azure Resource ManagerによるWebアプリケーション環境の展開~IaaS~」です。

システムの構成

システム構成は動作確認までの所要時間優先でLAMP(Linux+Apache+MySQL+PHP)を例に取りたいと思います。
まずシステム構成図です、図に全部盛りだとごちゃごちゃしてしまいましたので一部のリソースは省いています。

システム構成図

次にリソースの一覧です。

仮想マシンStandard_A2×4(AP×2/DB×2)
可用性セット ×2(AP×1/DB×1)
ストレージアカウントStandard_LRS×1
仮想ネットワーク ×1
ネットワークインターフェース ×4(AP×2/DB×2)
パブリックIPアドレス ×5(AP×2/DB×2/LB×1)
ネットワークセキュリティグループ ×2(AP×1/DB×1)
ロードバランサーExternal Load Balancer×1

テンプレートの作成

ARMの構成要素はただ一つリソースを定義するテンプレートファイル(json)だけです、このテンプレートファイルAzure PowerShellに食わせることでデプロイを行います。
テンプレートファイルですが、基本的にはパラメータ/変数/リソースを宣言するだけでコピペでも結構行けちゃいます。あとリソース間の依存関係はARM側で制御してくれますので、リソースの記述順を意識しなくて良いのがすごく楽です。

そして今回作成したテンプレートファイルです、ちょっと長いですが全文掲載します。

デプロイ

デプロイは下のようなPowerShellスクリプトで行います。

cd "C:\AzureColumn04"

Login-AzureRmAccount
Select-AzureRmSubscription -SubscriptionName "サブスクリプション名"

New-AzureRmResourceGroup -Name "azurecolumn04" -Location japanwest

# 展開用パラメータの設定
$parameter = @{
"adminUserName" = "管理者ユーザー"
"adminPassword" = "管理者パスワード"
}

# テンプレートのテスト
Test-AzureRmResourceGroupDeployment -ResourceGroupName "azurecolumn04" -TemplateFile .\azurecolumn04.json -TemplateParameterObject $parameter -Debug

# テンプレートを使用した展開
New-AzureRmResourceGroupDeployment -Name "azurecolumn04.deploy" -ResourceGroupName "azurecolumn04"  -TemplateFile .\azurecolumn04.json -TemplateParameterObject $parameter -Debug 

では実行してみましょう。

ログインアカウントの入力

Login-AzureRmAccountのところでAzureへのログインアカウントの入力が求められます。権限を絞り込むことも出来ると思いますが、すいません今回はサービス管理者権限を保持するユーザーで実行しています。

デプロイ中

デプロイ中は進行状況が逐一表示されます、が追いきれないので基本眺めているだけです。

ポータルではこんな感じです。

デプロイ完了

デプロイが完了すると、前回のデプロイに「成功」と表示されます

動作確認 (1)

ここまでではまだミドルウェアが入っていませんのでWebアプリケーションの確認は出来ませんが、仮想マシンの情報などを見て本当にデプロイが行われているかを確認してみましょう。

Get-AzureRMVMでリソースグループに4台の仮想マシンが作成されていることが確認できました。
では次は仮想マシン(AP1)へのSSHを確認してみましょう、IPアドレスはポータルまたはGet-AzureRmPublicIpAddressで取得してください。

SSHも無事行うことが出来ました、ひとまず仮想マシンは正常にデプロイされているようです。

ミドルウェアインストール&設定

ではあと一息ミドルウェアのインストール&設定を行って、Webアプリケーションの動作確認をしてみましょう。
実際に使用したコマンドと手順のサンプルを掲載します。

APサーバ

1. ミドルウェアのインストール

  • (1)  sudo apt-get update
  • (2)  sudo apt-get install mysql-server

2. AP用MySQLユーザーの作成

  • (1)  mysql -u root -p
     →  rootのパスワードを入力
  • (2)  create user mysqladmin identified by ‘パスワード';
  • (3)  grant all privileges on mysql.* to 'mysqladmin'@'%';

3. my.cnfの設定

  • (1)  sudo vi /etc/mysql/my.cnf
  • (2)  bindaddress行をコメントアウト

4. MySQL再起動

  • (1)  sudo /etc/init.d/mysql restart

動作確認 (2)

さあ最終動作確認です、ブラウザからロードバランサーのDNS名/テストモジュール名(本件では http://azurecolumn04-lb.japanwest.cloudapp.azure.com/phptest.php)にアクセスしてください。

成功です!ちょっとしょぼいですが一応MySQLから読み取った情報を表示できています。
念のためMySQLのクエリでも確認してみましょう。

一致が確認できました、これでAPからDBの情報が正しく読み取れていることが確認できましたね。

所要時間

テンプレートの作成秘密
デプロイ5分くらい
ミドルウェアインストール&設定30分くらい
削除5分くらい

まとめ

デプロイ~ミドルウェアインストール&設定~動作確認までの所要時間60分弱、いかがでしょうか?
しょぼくれたデモですので実際はもう少し時間かかると思いますがそれを差し引いてもやはり速いと思います。多分仮想マシンの払い出しくらいならオンプレミスでも同じくらいでできる可能性があると思いますが、ストレージやネットワークも込みとなるとさすがに無理でしょう。この速さがパブリッククラウドの最大の利点なのは間違いないですね。
次にテンプレートの作成について、これは最初から簡単とは言いませんが習熟による生産性の向上は期待できると言う感覚を持っています。あととにかく依存関係をARMで制御してくれるのが大きいです、これはクラシック時代のロジック込みのPowerShellスクリプトに比べて格段の進歩を感じた部分です。

次回予告

さて次回は「Azure Resource ManagerによるWebアプリケーション環境の展開~PaaS~」をお送りいたします。
PaaSでAPとDBだけだと多分面白くないと思いますので、SendGridやTraffic Managerなどの周辺リソースも組み合わせたいなとは考えています、がそこは苦戦具合に引っ張られますのでこうご期待と言う事で。
