# R-ISUCON-2018winter操作マニュアル --------------- はじめに以下の操作を行い、問題なく動くかを確認して下さい。 ### 2\. 起動したEC2インスタンスに `ubuntu` ユーザで SSH ログインする サーバーは全部で3台あります。 事前に連絡したサーバー全てにログインできるか確認してください。 例: ``` ssh -i <お渡しした鍵> ubuntu@<お渡ししたドメイン名> ``` ログイン後に`sudo su - isucon`ユーザーでログインできるようにすることをおすすめします。 もし、ログインできない場合は主催者に確認してください。 ### 3\. アプリケーションの動作を確認 EC2インスタンスのパブリックIPアドレスにブラウザでアクセスし、動作を確認してください。以下の画面が表示されるはずです。 例として、「アカウント名」は `kamome`、 「パスワード」は `tarou` を入力することでログインが行えます。 ブラウザでアクセスできない場合、主催者に確認してください。 ### 4\. 負荷走行を実行 この操作後、ポータルにて、あなたのチームのスコアが反映されているか確認して下さい。 ### ディレクトリ構成 参考実装のアプリケーションコードおよび、スコア計測用プログラムは `/home/isucon` ディレクトリ以下にあります。 ``` /home/isucon/ ├── env.sh # アプリケーション用の環境変 └── r-isucon └── webapps #各種言語実装 ├── go ├── java ├── ruby ├── nodejs ├── python └── sql #初期データ用SQL ``` ### 構成図 構成図は以下になります。ベンチマーカーはfrontendを経由しない点に注意してください。 各インスタンスのスペックは各自で確認してみてください。 ![](https://i.imgur.com/GtlNh74.png) ### 参考実装の言語切り替え方法 参考実装の言語はNodejs,Go,Java,Ruby,Pythonが用意されており、初期状態ではNodejsの実装が起動しています。 http://<お渡ししたドメイン名> アクセスできるので、ブラウザから動作確認をすることができます。 プログラムの詳しい起動方法は、 `/etc/systemd/system/r-isucon-node.service` を参照してください。 エラーなどの出力については、 ``` $ sudo journalctl -f -u r-isucon-nodejs ``` などで見ることができます。 #### Go言語への切り替え方 起動する実装をGoに切り替えるには、以下の操作を行います。 ``` $ sudo systemctl stop r-isucon-node $ sudo systemctl start r-isucon-go ``` #### Javaへの切り替え方 起動する実装をJavaに切り替えるには、以下の操作を行います。 ``` $ sudo systemctl stop r-isucon-noed $ sudo systemctl start r-isucon-java ``` #### Rubyへの切り替え方 起動する実装をRubyに切り替えるには、以下の操作を行います。 ``` $ sudo systemctl stop r-isucon-noed $ sudo systemctl start r-isucon-ruby ``` ### MySQL 3306番ポートでMySQLが起動しています。初期状態では以下のユーザが設定されています。 - ユーザ名: `root`, パスワード: `password!` - ユーザ名: `rmail`, パスワード: `passw0rd` ### Python 利用者向け #### ソースコードのダウンロード ``` sudo apt-get install zip -y cd r-isucon/webapps/ wget https://s3-ap-northeast-1.amazonaws.com/r-isucon-images/python.zip unzip python.zip ``` ``` sudo pip install pipenv cd ~/r-isucon/webapps/python/ pipenv install ``` ``` sudo vim /etc/systemd/system/r-isucon-python.service 以下を追記 ``` ``` [Unit] Description=r-isucon-python After=syslog.target [Service] User=isucon Group=isucon WorkingDirectory=/home/isucon/r-isucon/webapps/python Environment=PATH=/usr/local/python/bin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin Environment=NODE_ENV=production EnvironmentFile=/home/isucon/env.sh PIDFile=/home/isucon/r-isucon/webapps/python/server.pid ExecStart=/usr/local/bin/pipenv run python app.py ExecStop=/bin/kill -s QUIT $MAINPID [Install] WantedBy=multi-user.target ``` ``` sudo systemctl daemon-reload sudo systemctl start r-isucon-python ``` アクセスして起動確認
