Yii遷移問題

我是PHP和Yii PHP框架的新手。Yii遷移問題

我想在本地機器上運行一個應用程序。我首先需要遷移數據庫。對於這我運行下面的命令，

protected/yiic migrate

但它拋出CDbException與以下堆棧跟蹤...

Yii Migration Tool v1.0 (based on Yii v1.1.14) 

exception 'CDbException' with message 'CDbConnection failed to open the DB connection: could not find driver' in /var/www/Prepaid-Card/web/framework/db/CDbConnection.php:382

#14 /var/www/Prepaid-Card/web/protected/yiic(4): require_once('/var/www/Prepai...')

這裏是我的console.php文件

<?php 

return array(
    'basePath' => dirname(__FILE__) . DIRECTORY_SEPARATOR . '..', 
    'name' => 'Prepaid Card', 
    // preloading 'log' component 
    'preload' => array('log'), 
    'import' => array(
     'application.models.*', 
     'application.components.*', 
     'application.extensions.*', 
     'ext.YiiMailer.YiiMailer' 
    ), 
    // application components 
    'components' => array(
     'db' => require(dirname(__FILE__) . '/../../../../DbConfig.php'), 
     'log' => array(
      'class' => 'CLogRouter', 
      'routes' => array(
       array(
        'class' => 'CFileLogRoute', 
        'levels' => 'error, warning', 
       ), 
      ), 
     ), 
    ) 
);

我已經安裝的MySQL並創建了後續的數據庫。我的DbConfig文件看起來像

<?php 
return array(
    'connectionString' => 'mysql:host=localhost;dbname=db_ppc', 
    'emulatePrepare' => true, 
    'username' => 'root', 
    'password' => 'helloworld', 
    'charset' => 'utf8', 
);

我只是想不通這裏的問題。

我在做什麼錯在這裏？這個問題的原因是什麼？請幫我解決它。

謝謝！

這是數據庫連接錯誤檢查你的mysql連接 –

你在你的系統中安裝了PDO嗎？ – JorgeeFG

是的，但@ramamoorthy_villi我有一個正確的連接證書的MySQL ...這就是問題所在？我無法弄清楚我做錯了什麼？ – Runcorn

「CDbConnection無法打開數據庫連接：無法找到驅動程序」。這個消息告訴你在你的環境中配置的東西不好。檢查您的PHP配置數據庫驅動程序，並重新啓動/重新加載您的Apache加載新的配置。
