概要
Vagrant上のCentOS7仮想環境にComposerをグローバルインストールした記録。
PHPを使ってダウンロード、インストールするのでLinuxの種類には依存しない。
手順の確認
実行スクリプト
ComposerのサイトでDownloadの内容を確認。シンプルに進めるなら以下のスクリプトをターミナルで実行するよう書かれている。
|
1 2 3 4 |
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" php -r "if (hash_file('sha384', 'composer-setup.php') === '756890a4488ce9024fc62c56153228907f1545c228516cbf63f885e036d37e9a59d27d63f46af1d4d07ee0f76181c7d3') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" php composer-setup.php php -r "unlink('composer-setup.php');" |
それぞれphpのスクリプトを-rオプションで直接実行している。
- 1行目はインストールファイルのダウンロード
- 2行目はファイルの確認
- 3行目でセットアップ実行
- セットアップファイルの削除
オプション
composer-setup.phpを実行するときのオプションに以下が説明されている。
- –install-dir
- 実行ファイルをインストールするディレクトリーを指定する。
php composer-setup.php --install-dir=bin- –filename
- インストールする実行ファイル名を指定する。デフォルトは
composer.phar php composer-setup.php --filename=composer
その他に--versionと--helpも説明あり。
グローバルインストール
指定したファイルにローカルインストールする方法もあるが、ここでは/usr/local/binにグローバルインストールする。

セットアップ実行の際に、/usr/local/binに書き込むためroot権限で実行し、セットアップするディレクトリーとファイル名(composer)を指定している。
プロンプトにcomposerと入力してインストールされたことを確認。
