Laravel can't connect to DB

问题

I'm following through the Quick Start Guide, and got to the section actually connecting to the DB to fetch the users table, and am getting the following error:

SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: NO)

My database.php includes the following setup (default set to mysql):

'mysql' => array(
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => 'bt',
    'username'  => 'root',
    'password'  => '',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),

When I go to the terminal window, however, I'm able to log in using mysql -h localhost -u root -p then just hit enter to go in without a password, which I thought would be equivalent (the 'bt' table shows up when I run show databases();). What am I missing here?

回答1:

I think this is the solution :)

'mysql' => array(
    'driver'    => 'mysql',
    'host'      => '127.0.0.1',
    'database'  => 'bt',
    'username'  => 'root',
    'password'  => '',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefi

It's also possible that pdo is not installed on your machine. You can check if it's installed from the phpinfo() page or a php script

if ( extension_loaded('pdo') ) {
    .......
}

On linux you can install it by

sudo apt-get install php5-mysql
