在使用yii的yii\db\Connnection时发生错误
<?php namespace app\controllers; use yii\web\Controller; use yii\db\Connection; use Yii; class MyController extends Controller { public function actionIndex() { $country = Yii::$app -> db -> createCommand("select * from country") -> queryAll(); print_r($country); } }
错误:
解决方法:将config目录下的db.php配置文件中的localhost改为127.0.0.1即可
<?php return [ ‘class‘ => ‘yii\db\Connection‘, ‘dsn‘ => ‘mysql:host=localhost;dbname=yii‘, ‘username‘ => ‘root‘, ‘password‘ => ‘12‘, ‘charset‘ => ‘utf8‘, ];
当主机填写为localhost时mysql会采用 unix domain socket连接
当主机填写为127.0.0.1时mysql会采用tcp方式连接
这是linux套接字网络的特性,win平台不会有这个问题
YII 错误 SQLSTATE[HY000] [2002] No such file or directory
