我是 yii2 的新手。我在 advaced/common/config/main-local.php 中添加了数据库名称和用户名。使用 xampp 网络服务器和 php 版本是 5.6.8 并且还启用了 PDO。

这是我的数据库配置。

'db' => [
        'class' => 'yii\db\Connection',
        'dsn' => 'mysql:host=localhost;dbname=yii2advanced',
        'username' => 'root',
        'password' => '',
        'charset' => 'utf8',
    ],

在 Yii2 上找到这个

"Most likely it is your system config. If you are using packages like MAMP, XAMPP or other, you may need to change "localhost" to "127.0.0.1" in your db.php configuration file. Also if you are on Linux you may need to install some other additional packages like php5-mysql and stuff like that."
