[Laraval4][Resolved] Access denied for user 'homestead'@'localhost'

PDOException (1045)
SQLSTATE[HY000] [1045] Access denied for user 'homestead'@'localhost' (using password: YES)

If you got this error message, mean Laravel can not access you database with your configuration.
First of all, what you should do is to check up your configuration in database.php which located in this directory:

your_project_root/app/config/database.php

For my case, I use mysql as my database so check the 'mysql' array value in database.php file. (change text in red to your text)

'mysql' => array(
    'driver'    => 'mysql',
    'host'      => '127.0.0.1',
    'database'  => 'testing',
    'username'  => 'user',
    'password'  => '123',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),

If the error message still appear if you comfirm your database configuration are correct, you should check is the environnement value "$env" in your project changed the as local or development.
(file path to check environement value:)

your_project_root/bootstrap/start.php

You should visit the "database.php " in "config/local" folder since Laravel would load the config files within this folder if you have set envirnment as development.


path :

your_project_root/app/config/local/database.php

for my case, I changed array value of "'mysql'" from 

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

to resolved this Access denied for user 'homestead'@'localhost' problem. (change text in red to your text)

'mysql' => array(
    'driver'    => 'mysql',
    'host'      => '127.0.0.1',
    'database'  => 'testing',
    'username'  => 'user',
    'password'  => '123',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),
