使用迁移工具Yii错误

Question

我正在尝试使用迁移工具,但收到以下错误:

exception 'CDbException' with message 'CDbConnection failed to open the DB connection: SQLSTATE[HY000] [2002] Connection refused' in /Applications/MAMP/htdocs/yii-sandbox/framework/db/CDbConnection.php:382

#14 /Applications/MAMP/htdocs/yii-sandbox/projects/trackstar/protected/yiic(4): require_once('/Applications/M...')

我已经检查了数据库设置console.php,如下所示:

'db'=>array(
    'connectionString' => 'mysql:host=127.0.0.1;dbname=yii_trackstar, unix_socket=/Applications/MAMP/tmp/mysql/mysql.sock',
    'emulatePrepare' => true,
    'username' => 'yii',
    'password' => 'xxx',
    'charset' => 'utf8',
),

如您所见,我已尝试将主机设置为127.0.0.1并根据其他建议设置unix套接字.

我正在使用MAMP(如你所见).从受保护的目录,我正在运行命令:./yiic migrate

无论我改变什么,我都会收到相同的错误消息.

*更新:*

我刚刚意识到了什么.更改host=localhost到host=127.0.0.1实际给我的一个不同的错误connection refused.如果我将其设置回localhost错误如下:

exception 'CDbException' with message 'CDbConnection failed to open the DB connection: SQLSTATE[HY000] [2002] No such file or directory' in /Applications/MAMP/htdocs/yii-sandbox/framework/db/CDbConnection.php:382

你可以查看yii框架论坛,已经有类似的问题发布在http://www.yiiframework.com/forum/index.php/topic/16-db-connection-string

注意

具体来说,解决它的是这个线程:

关于PHP和Mac OSX的说明:Mac OSX捆绑了一个PHP4版本,通常是从命令行尝试php命令时执行的版本.您需要让php命令执行PHP5.x或更高版本.通常,您已经安装了PHP5.x或更高版本,但需要告诉php命令执行较新版本而不是较旧版本.当然有很多方法可以达到这个目的,但这里有一个:

在任何终端提示符下键入:

prompt>which php

这应该告诉你操作系统在哪里寻找php命令告诉我/usr/bin/php.如果我导航/usr/bin并发出一个ls *php*我会看到三个文件:

php
php-config
phpize

这些都是针对捆绑版本的PHP4.x重命名这些文件以在其名称中使用4,以记住这些是PHP4的可执行文件

mv php php4
mv php-config php-config4
mv phpize phpize4

然后,为这些中的每一个创建sym链接以指向您已安装的PHP5.x或更高版本.在我的情况下,这些位于/usr/local/apache/php/bin.所以我会从/usr/bin目录发出

ln -s [absolute path to your php5.x] php

和其他文件类似.
