The error message is clear: the MySQL database access driver could not be found.

The extension was probably not enabled. Check out your php.ini . On Windows, something like:


On other systems, something like:


A Windows user said that Yii requires extension=php_pdo_mysql.dll (that is, " php_pdo_mysql " instead of " php_mysql ").

It is also important to remember restart PHP and / or Apache after making changes to the configuration files.

Your DSN shows that you are trying to use the MySQL driver and the error indicates that the driver is unavailable.

Verify that the extension is installed.

In Ubuntu / Debian you can do the following to verify that it is installed

dpkg --get-selections | grep php5-mysql

If it is not, you can install it as well

sudo apt-get install php5-mysql

Then restart apache for the new settings to take effect.

sudo /etc/init.d/apache2 restart

If already installed check which host MySQL is accepting connections to. Run

sudo nano /etc/mysql/my.cnf

Change bind-address to to listen for connections from any IP.

bind-address =

Give connection permission for all IPs

mysql -u root -p

At the MySQL prompt type

use mysql
// Caso o root não possua senha use
GRANT ALL PRIVILEGES ON *.* TO [email protected]'%'
// Se tiver senha use
GRANT ALL ON *.* to [email protected]'%' IDENTIFIED BY 'senha';

Restart MySQL

sudo /etc/init.d/mysql restart
