Yii：如何远程连接到数据库？

Question

I am trying to connect to a db remotely using the Yii framework

Is there any specific setting because i can't connect to the db.

'db' => array(
    'class' => 'PortalDbConnection',
    'connectionString' => 'mysql:host=192.168.0.2;dbname=mydb',
    'username' => 'root',
    'password' => '',
    'tablePrefix' => '',
    'emulatePrepare' => true,
    'enableParamLogging' => true,
    'enableProfiling' => true,
    'charset' => 'utf8',
),

Error

2013/10/16 09:14:22 [error] [exception.CDbException] SQLSTATE[HY000]
[2003] Can't connect to MySQL server on 'mysql5.ms.domain.net' (13)

Answer 1

This code is valid for me:

'db'=>array( 
        'connectionString' => 'mysql:host=192.168.1.96;dbname=dbname',
        'emulatePrepare' => true,
        'username' => 'root',
        'password' => '',
        'charset' => 'utf8',
        'enableProfiling'=>true,
        'enableParamLogging' => true,
    ),

Do you have configurated on the DB server the %root access, from remote?

Edited:

For configure remote access:

There's two steps in that process:

a) Grant privileges. As root user execute:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password';

b) bind to all addresses:

The easiest way is to comment out the line in your my.cnf file:

#bind-address = 127.0.0.1 

and restart mysql

service mysql restart
