先の記事、
の続きです。
実際に、9 ドメイン 180 FQDN(Let's Encrypt で 1 週間に 9 ドメインに対して発行できる限界)で試してみました。
※本当は 10 ドメイン作ったのですが、.nagoya
ドメインの Route 53 への移行で、運悪くお名前.com のネームサーバからの切り替えに時間が掛かってしまい、テストでの利用を断念しました…。
テストの内容
-
curl
コマンドで対象 FQDN に対してリクエストを送り、**time_starttransfer
**を計測 - 動的に SSL/TLS 証明書を読み込むテストでは、1 ドメインあたり 20 FQDN × 10 回を、
cron
を使って 5 ドメイン/ 9 ドメイン並行でリクエストを送る - 静的に SSL/TLS 証明書を読み込むテスト(比較用)では、1 FQDN に対して同じ数だけ並行してリクエストを送る
- 主にハンドシェイクに掛かる時間の差(動的 vs 静的)を計測する
- 使用インスタンスは AWS EC2 の m4.large(CentOS 7)
- nginx(OpenResty)と同じインスタンスに Apache で Web サーバを起動(パッケージインストール後、ほぼ初期設定のまま:レスポンスは 403 で Welcome ページが返る状態)
結果
ドメイン(並行)数 | FQDN 数 | 総リクエスト | 静的 (a) | 動的 (b) | 増加率 |
---|---|---|---|---|---|
5 | 100 | 1,000 | 0.306s | 0.318s | 3.95% |
9 | 180 | 1,800 | 0.443s | 0.454s | 2.33% |
※静的・動的の数値は 1 リクエストあたりの平均値。
いずれも、トータルの所要時間は 60 秒(5 ドメイン並行時)強・90秒(9 ドメイン並行時)強でした。
リクエスト毎の記録は掲示しませんが、特に時間が順に延びていくこともなく、この程度の負荷では動的処理のオーバーヘッドはごくわずかであることが分かりました。
参考/テスト環境の構築について
今回は、以下の流れで環境を用意しました。
リバースプロキシ/Web サーバ側
EC2 インスタンスを用意
- EC2 に割り当てる IAM Role を作成(
AmazonRoute53FullAccess
ポリシー付き) - CentOS 7 の AMI から EC2 インスタンスを作成(↑を割り当て)
- 要 awscli・httpd・openssl
-
aws configure
でデフォルトリージョンを指定(aws
コマンドを使うユーザで) -
/etc/httpd/conf.d/ssl.conf
をリネーム(.bak
などに)
-
- OpenResty と Certbot クライアントをインストール
- 要 awscli・httpd・openssl
お名前.com でドメイン取得
EC2 から Route 53 の Public Hosted Zone を登録
$ cat create_zone_hmatsu47.sh
#!/bin/sh

$ sh ./create_zone_hmatsu47.sh
※hmatsu47.site
は元から登録済。
各 Zone の NS の内容をお名前.com で DNS(その他)に設定。
登録完了を待つ間に各 Zone のレコードを登録。
