访问被拒绝使用yii连接到mysql

Question

I get this error when trying to connect to my db with Yii

I am sure the password and permissions are correct. How do I track down the problem here?

I am running MAMP and the latest Yii.

CDbException

CDbConnection failed to open the DB connection: SQLSTATE[28000] [1045] Access denied for user 'yii'@'localhost' (using password: YES)

/Users/user/Dropbox/localhost/yii/framework/gii/generators/model/ModelCode.php(54)

42         ));
43     }
44 
45     public function requiredTemplates()
46     {
47         return array(
48             'model.php',
49         );
50     }
51 
52     public function init()
53     {
54         if(Yii::app()->db===null)
55             throw new CHttpException(500,'An active "db" connection is required to run this generator.');
56         $this->tablePrefix=Yii::app()->db->tablePrefix;
57         parent::init();
58     }
59 
60     public function prepare()
61     {
62         if(($pos=strrpos($this->tableName,'.'))!==false)
63         {
64             $schema=substr($this->tableName,0,$pos);
65             $tableName=substr($this->tableName,$pos+1);
66         }

Answer 1

In the file /protected/config/main.php look for the "components" block and update as needed:

'components'=>array(
    'db'=>array(
        'connectionString' => 'mysql:host=HOSTNAME;dbname=DBNAME',
        'emulatePrepare' => true,
        'username' => 'MYSQL_USER',
        'password' => 'MYSQL_PASS',
    ...

(change UC vals to your settings). And read these pages .

Answer 2

Make sure you have entered your database info in the correct configuration file (in /config ). Presumably Gii is using the main.php config file, so make sure you didn't set up the DB credentials in console.php or test.php by accident instead on main.php .

Answer 3

确保您更改console.php中的凭据（yiic不会寻找main.php，尽管它重复了相同的Thins）

Answer 4

Here I have working code:

OS Ubuntu:

<?php

return [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=192.168.1.11;dbname=yiidemo',
'username' => 'yiidemo',
'password' => 'yiidemo!23',
'charset' => 'utf8',
];

Working for me :-)

Answer 5

I had this problem. Solved it by:
Open file yii/config/db.php
and add your data for phpmyadmin (password&name).

Answer 6

If you are sure that the supplied credentials are correct, then the yii user must not have permission to connect from localhost . MySQL authentication is done by username, password, and host, so it reads like one of those is incorrect.

Answer 7

If you are using mamp on a local machine make sure your username is set to 'root' and the password is set to 'root' in the main.php file. The default is to set password to null and this will cause the error above.
