        #20 {main}

我是yii2的新手.我在advaced/common/config/main-local.php中添加了数据库名称，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.

I am new to yii2. I have added database name,username in advaced/common/config/main-local.php. Using xampp webserver and version of php is 5.6.8 and PDO is also enabled.

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',
    ],

推荐答案

在

"很可能是您的系统配置.如果您使用的是类似 MAMP，XAMPP或其他，您可能需要将"localhost"更改为 db.php配置文件中的"127.0.0.1".另外，如果你在 Linux，您可能需要安装其他一些其他软件包，例如 php5-mysql之类的东西."

"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."
