Yii 控制台命令无法连接到数据库

Question

我正在尝试在 Yii 中设置控制台命令，并且可以很好地回显命令，但我无法让命令执行任何有用的操作。我试图让它插入一条记录，但我似乎无法连接到我的数据库 - 尽管事实上我的实际应用程序运行良好 - 具有相同的连接细节。

我假设 console.php 配置文件不正确 - 但我不知所措。这是我的控制台配置文件

// This is the configuration for yiic console application.
// Any writable CConsoleApplication properties can be configured here.
return array(
    'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
    'name' => 'My Console Application',

    // preloading 'log' component
    'preload'=>array('log'),
    //import
    'import' => array(
        'application.models.*',
        'application.components.*',
        'application.extensions.*',
    ),
    // application components
    'components'=>array(
        'db' => array(
            'connectionString' => 'mysql:host=localhost;dbname=xxx',
            'emulatePrepare' => true,
            'username' => 'xxx',
            'password' => 'xxx',
            'charset' => 'utf8',
            'tablePrefix' => 'sys_',
            'class' => 'CDbConnection'
        ),
        'log'=>array(
            'class'=>'CLogRouter',
            'routes'=>array(
                array(
                    'class'=>'CFileLogRoute',
                    'levels'=>'error, warning',
                ),
            ),
        ),
    ),
    'params' => array(
        'keyword' => 'test',
    ),
);

我什至无法让我的控制台命令再次写入日志，尽管我的实际应用程序写得很好。这是我的命令

class NewSysCommand extends CConsoleCommand {

    public function test() {
        echo "\nI've ran a sys test command successfully!\n\n";
        Yii::log('Command test to write to log', 'error');
    }

    public function captureIssueResponse(){
        Yii::log('captureIssueResponse write to log', 'warning');

        //Create our booking
        $issueResponse = new IssueResponses();
        $issueResponse->issue_id = 40;
        $issueResponse->ticket_id = "1111";
        $issueResponse->response = "new response from command line 1";
        $issueResponse->save();
    }

    public function run($args) {
        self::test();
        self::captureIssueResponse();
        return 0;
    }

}

这是我尝试使用“protected/yiic newSys”在控制台中运行命令时遇到的错误

I've ran a sys test command successfully!

谁能看到我做错了什么？

您应该将主机更改为 127.0.0.1 或尝试像这样使用 MySQL 套接字：

mysql:host=localhost;dbname=xxxx;unix_socket=/Applications/MAMP/tmp/mysql/mysql.sock

这适用于 MAMP，但也可能适用于 XAMPP。
