apache2でマルチドメイン（Virtual Host）の運用をする

【キーワード】

apache2,マルチドメイン,Virtual Host

【目的】

Apach2で独自ドメインを運用する。
mod_rewirteモジュールの有効化を実施する。

【ドメイン】

hogehoge.com（便宜上ドメインは各自の環境で読み替える）

【アプローチ】

１：Apache2の設定ファイルを新規作成(hogehoge.com.confの作成)
　┣【ファイルの作成】を参照
　┗ <修正前データ（元データ）>を参照し<修正後データ>に

２：公開用のディレクトリを作成する

$ sudo mkdir -p /var/www/vhost/sesiri.club/html
$ sudo chown -R www-data:www-data /var/www/vhost/

３：a2ensiteコマンドで、設定を登録する
$ sudo a2ensite hogehoge.com.conf

４：Apache2、再読込処理

$ sudo service apache2 reload

<ここからmod_rewriteの設定>

５：mod_rewriteが利用可能になっているかを確認する
$ cat /etc/apache2/mods-available/rewrite.load
LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so

６：a2enmodコマンドでmod_rewriteを実行する
$ sudo a2enmod rewrite

７：Apache2の再起動を実行
$ sudo service apache2 restart


【バージョンの確認】

<Apach2のバージョン>

$ apachectl -v
Server version: Apache/2.4.18 (Ubuntu)
Server built:   2016-07-14T12:32:26

【ファイルの作成】

$ sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/hogehoge.com.conf

        # value is not decisive as it is used as a last resort host regardless.
