Db的配置文件（默認）

好心幫我

這是安裝控制器代碼

Answer 1

嘗試這樣，

'db'=>array(
        'connectionString' => 'mysql:host=localhost;dbname=sarish', 
        'class'=>'CDbConnection', 
        'emulatePrepare' => true, 
        'username' => 'sarish', 
        'password' => 's@r15h', 
        'charset' => 'utf8', 
        'tablePrefix' => '', 
      ), 

Answer 2

嘗試改變localhost到你的IP地址127.0.0.1並添加端口號，看看會發生什麼。

'connectionString' => 'mysql:host=127.0.0.1;port=3306;dbname=sarish',

我有這個問題太，這是我在這裏的解決方案，我想你的雙重配置數據庫連接，MySQL錯誤：使用密碼：NO意味着你的密碼是空的....所以看一看/通用/ config/main-local.php，這裏有一個db連接的預配置，所以你不需要在任何其他配置文件中配置db連接.....我的英語不好，但我希望你能理解我..
