Laravel can not connect mariaDB on CentOs 7.2

Question

How to configure MariaDB in Laravel 5?

The thread above mentioned that changing port 3306 to 3307,I tried it but still not work.

I write my code on local Windows,the port is also 3306, and the app can run, I copy the app to cloud host,OS is CentOs 7.2,the error appears.

And I am using Laravel 5.3 and mariaDB 10.2 .

The .env file is like this：

DB_USERNAME=root
DB_PASSWORD=123456

config/database.php

'mysql' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST', 'localhost'),
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'forge'),
    'username' => env('DB_USERNAME', 'forge'),
    'password' => env('DB_PASSWORD', ''),
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix' => '',
    'strict' => true,
    'engine' => null,
],

I can access it via terminal：

# mysql -uroot -p123456;
MariaDB [(none)]> 

When running php artisan migrate ，there is an error：

  [PDOException]                                                                         
  SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO)

What should I do？

Answer 1

check your DB_PASSWORD setting in .env file.

The error information says that using password: NO which meant no password used when connecting to db.
