Yii迁移问题

我是PHP和Yii PHP框架的新手。Yii迁移问题

我想在本地机器上运行一个应用程序。我首先需要迁移数据库。对于这我运行下面的命令，

protected/yiic migrate

但它抛出CDbException与以下堆栈跟踪...

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...')

这里是我的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', 
       ), 
      ), 
     ), 
    ) 
);

我已经安装的MySQL并创建了后续的数据库。我的DbConfig文件看起来像

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

我只是想不通这里的问题。

我在做什么错在这里？这个问题的原因是什么？请帮我解决它。

谢谢！

这是数据库连接错误检查你的mysql连接 –

你在你的系统中安装了PDO吗？ – JorgeeFG

是的，但@ramamoorthy_villi我有一个正确的连接证书的MySQL ...这就是问题所在？我无法弄清楚我做错了什么？ – Runcorn

“CDbConnection无法打开数据库连接：无法找到驱动程序”。这个消息告诉你在你的环境中配置的东西不好。检查您的PHP配置数据库驱动程序，并重新启动/重新加载您的Apache加载新的配置。
