CakePHP 4のインストール
前回はMySQLをセットアップしました。今回はCakePHPをインストールしたいと思います。
まずはcomposerのバージョンを確認します。
$ composer --version ↵ Composer 1.6.3 2018-01-31 16:28:17
composerを使ってCakePHP4をインストールします。
$ cd cd /vagrant_data/ ↵ $ composer create-project --prefer-dist cakephp/app:4.* cms ↵ Installing cakephp/app (4.0.3) - Installing cakephp/app (4.0.3): Downloading (100%) Created project in cms Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 80 installs, 0 updates, 0 removals - Installing cakephp/plugin-installer (1.2.0): Downloading (100%) PHP Fatal error: Uncaught Error: Class 'Cake\Composer\Installer\PluginInstaller' not found in /usr/share/php/Composer/Plugin/PluginManager.php:201 Stack trace: #0 /usr/share/php/Composer/Installer/PluginInstaller.php(63): Composer\Plugin\PluginManager->registerPackage() #1 /usr/share/php/Composer/Installer/InstallationManager.php(173): Composer\Installer\PluginInstaller->install() #2 /usr/share/php/Composer/Installer/InstallationManager.php(160): Composer\Installer\InstallationManager->install() #3 /usr/share/php/Composer/Installer.php(588): Composer\Installer\InstallationManager->execute() #4 /usr/share/php/Composer/Installer.php(227): Composer\Installer->doInstall() #5 /usr/share/php/Composer/Command/CreateProjectCommand.php(193): Composer\Installer->run() #6 /usr/share/php/Composer/Command/CreateProjectCommand.php(145): Composer\Command\CreateProjectCommand->installProject() #7 /usr/share/php/Symfony/Component/Console/Command/Command.php(252): Composer\Command\CreateProjectCommand->execute() #8 /usr/share/php/Symfony/Compo in /usr/share/php/Composer/Plugin/PluginManager.php on line 201 Fatal error: Uncaught Error: Class 'Cake\Composer\Installer\PluginInstaller' not found in /usr/share/php/Composer/Plugin/PluginManager.php:201 Stack trace: #0 /usr/share/php/Composer/Installer/PluginInstaller.php(63): Composer\Plugin\PluginManager->registerPackage() #1 /usr/share/php/Composer/Installer/InstallationManager.php(173): Composer\Installer\PluginInstaller->install() #2 /usr/share/php/Composer/Installer/InstallationManager.php(160): Composer\Installer\InstallationManager->install() #3 /usr/share/php/Composer/Installer.php(588): Composer\Installer\InstallationManager->execute() #4 /usr/share/php/Composer/Installer.php(227): Composer\Installer->doInstall() #5 /usr/share/php/Composer/Command/CreateProjectCommand.php(193): Composer\Installer->run() #6 /usr/share/php/Composer/Command/CreateProjectCommand.php(145): Composer\Command\CreateProjectCommand->installProject() #7 /usr/share/php/Symfony/Component/Console/Command/Command.php(252): Composer\Command\CreateProjectCommand->execute() #8 /usr/share/php/Symfony/Compo in /usr/share/php/Composer/Plugin/PluginManager.php on line 201
エラーが発生しています。
パッケージでインストールしたcomposerのバージョンが古かったのでしょうか？
最新にしてみます。まずはパッケージのcomposerをアンインストールします。

composerの公式ドキュメントに従って作業を進めます。
まずインストーラをダウンロードします。
$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" ↵
PHP Warning: copy(): SSL: Connection reset by peer in Command line code on line 1
PHP Warning: copy(): Failed to enable crypto in Command line code on line 1

え！
SSLのエラーです。一般的にこの手のエラーはルートCAの証明書が手元にないときに発生します。
Google先生にお伺いを立てても概ね証明書を指定するようにと言われます。
では、そのようにしてみましょう。
$ ls -l /etc/ssl/certs/ca-* ↵ -rw-r--r-- 1 root root 207436 Apr 16 15:54 /etc/ssl/certs/ca-certificates.crt
ca-certificates.crtが既に手元にありましたので、このファイルを明示してみます。
$ cd /etc/php/7.4/cli/ ↵ $ sudo cp -p php.ini php.ini.ORG ↵ $ sudo vi php.ini ↵
openssl.cafileディレクティブを探して、ca-certificates.crtをフルパスで指定してみます。
/etc/php/7.4/cli/php.ini

を次のように修正します。

念のため/etc/php/7.4/apache2/php.iniも同様に編集します。
再びダウンロードを試みます。
$ cd ↵

変わりませんね。
当然と言えばそうかもしれません。
ComposerからLaravelを導入しようとしてOpenSSL周りのエラーで困った件によると、http://curl.haxx.se/ca/cacert.pemをダウンロードして組み込めばよいらしいです。
それでは早速やってみましょう。
$ wget http://curl.haxx.se/ca/cacert.pem ↵ $ sudo cp -v -f cacert.pem /etc/ssl/certs/ca-bundle-curl.crt ↵
今回は、openssl.cafileディレクティブとcurl.cainfoディレクティブを探して、ca-bundle-curl.crtをフルパスで指定してみます。
$ sudo vi /etc/php/7.4/cli/php.ini ↵

ダメもとで、ダウンロードを試みます。
$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" ↵
あれ？
ダウンロードが成功しました。
腑に落ちませんが、良しとして続きの処理を行います。
$ php -r "if (hash_file('sha384', 'composer-setup.php') === 'e0012edf3e80b6978849f5eff0d4b4e4c79ff1609dd1e613307e16318854d24ae64f26d17af3ef0bf7cfb710ca74755a') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" ↵
Installer verified
$ php composer-setup.php ↵
All settings correct for using Composer
Downloading...
The "https://getcomposer.org/versions" file could not be downloaded: SSL: Connection reset by peer
Failed to enable crypto
failed to open stream: operation failed
Retrying...
Composer (version 1.10.5) successfully installed to: /home/vagrant/composer.phar
Use it: php composer.phar
やはりエラーが出ました。
原因と対処方法がわかりません。どなたかわかる方がおられたらお教えください。
CakePHPの公式ドキュメントによれば、Composerを使わない方法もあるようです。
次は、Composerを使わない方法で試してみようと思います。
