この記事は最終更新日から1年以上が経過しています。

この記事はDrupal Advent Calendar 2015の14日目の記事です。

11月19日にリリースされたばかりのDrupal8は、GUIでの画面操作やディレクトリ構成も刷新されていて、これまで以上に利便性が向上しています。

また、DrupalをCUIから操作するDrushもD8に対応しています。

コマンドラインで実行可能なDrushを既に利用して、データ管理の自動化を行っている方も居ると思いますが、改めてこの記事ではDrupal8@CentOS7の動作環境下にcomposer経由でDrushの8.0.1を入れ、実際動作するまでを記して行きたいと思います。

Drupal8@CentOS7の構築方法については、Drupal Advent Calendar 2015の4日目の記事として自分が投稿した記事「CentOS7に D8を入れてみた」
http://qiita.com/m_46/items/2acd238253e9fb1a45fd
をご参考頂ければと思います。

以後は、構築が完了したCentOS7@Drupal8の環境下でのdrush導入手順です。

composerの導入

まずはcurl経由でcomposerを導入します。

[root@cent7d8 ~]# curl -sS https://getcomposer.org/installer | php

動作確認をします。
[root@cent7d8 ~]# php composer.phar

composerが展開されるディレクトリを作成します。
[root@cent7d8 ~]# mkdir /root/.composer

composer.pharをディレクトリ内に格納します。
[root@cent7d8 ~]# mv ./composer.phar .composer/

環境変数を設定します。

/root/.bash_profile
alias composer='php /root/.composer/composer.phar'

その後、「.bash_profile」に記述した環境変数を適用します。
[root@cent7d8 ~]# source ~/.bash_profile

helpコマンド等を実行してみて問題無く実行できたらcomposerのインストールは完了です。
[root@cent7d8 ~]# composer help

composer経由のdrushの導入

composer経由でdrush8をインストールします。
[root@cent7d8 ~]# composer global require drush/drush:8.*

drushのインストール時の画面出力
Changed current directory to /root/.composer
./composer.json has been created

ここまで画面が出ればインストールが完了です。

次にdrushの環境変数を登録します。

vim:/root/.bash_profile
PATH="/root/.composer/vendor/bin:$PATH"

再度環境変数を適用します。
[root@cent7d8 ~]# source ~/.bash_profile

drushのバージョン確認をします。8.0.1がcomposer経由でインストール出来る現時点での最新版となります。

drushのバージョン確認
[root@cent7d8 ~]# drush --version
 Drush Version   :  8.0.1

drushコマンドの実行

drushのsh化

その後、実行するバックアップコマンドをshに書き出してみましょう。
ここでは6時間おきにDrupalのキャッシュをクリアするコマンドをsh化してみます。

/root/cache-clear.sh
#!/bin/sh

cd {drupalのルートパス}
drush cc all

shの実行権限追加
[root@cent7d8 ~]# chmod +x /root/cache-clear.sh

以上でshの作成は完了です。

shのcrontabへの登録

その後crontabに登録します。

[root@cent7d8 ~]# crontab -e

* */6 * * *  sh /root/cache-clear.sh >/dev/null 2>&1

上記の設定で6時間間隔でキャッシュのクリアが実行されます。

その他のdrushコマンド

その他、以下は使用頻度が高いであろうコマンドです。

- core のアップデート
drush pm-update

- バックアップ
drush archive-dump

- メンテナンスモード
drush vset maintenance_mode 1 --yes

- メンテナンスモード解除
drush vset maintenance_mode 0 --yes

メンテナンスモードからアップデートやバックアップ、キャッシュのクリアまでは自動化を実装する事は可能ですが、事前に実行するコマンドを「-d」でデバッグしてみたり「-s」でシミュレートしてみたり「-v」でログ出力をして実行結果が正常終了するなどを確かめた後で自動化を行えば、より精度の高い自動化を実装出来るのではないかと考えます。

まとめ

ケースによっては自動化は厳しい場合もあるかも知れませんが、これまで手動で行ってきた処理を定期自動実行する事で、コンテンツ運営の自動化を実現させるという意味では、この機能を活用しない手はないと思います。

これにて私の「Drupal Advent Calendar 2015」の12月14日分の投稿を終了します。
