Access denied for user 'root'@'localhost' - Laravel

Question

I have an application with Laravel 4, that runs in localhost correctly, but when I uploaded it in my host I received the error .

app>config>database.php file is:

'mysql' => array(
        'driver'    => 'mysql',
        'host'      => '127.0.0.1',
        'database'  => 'forum',
        'username'  => 'root',
        'password'  => '',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
    ),

And bootstrap>start.php is:

$env = $app->detectEnvironment(array(
'local' => array('homestead'),
));

Answer 1

This worked for me:

php artisan config:clear

Even though I changed the config details in the .env file, I was getting the Access denied error. Running the above command will clear configuration cache file and hence laravel will read the fresh data from the .env file.

You must find out the credentials of Database host, Database Name , Database Username and Database Password . (If any prefix for tables too) and then replace it with the current credentials.

Use the concept of environments and store values in ENV variables :

http://laravel.com/docs/4.2/configuration

You can store Env Variables as array in .{ENV_NAME}.env.php and access those variables as $_ENV['variable_name'].

Answer 3

Maybe you should add double-quotes for password in env:

# Config: database
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db_name
DB_USERNAME=db_user
DB_PASSWORD="db_password"

and

php artisan config:clear

Check your mysql database is running perfectly or not. Then check you db user root in mysql with no password and restart your server.
