I think i know what is going on. I have had to change my database connection to 192.168.10.10 in PHPStorm to connect to MySQL because the MySQL is on the homestead VM (virtual machine) and i cant connect to it locally because technically its on a "Different Machine". So then i went looking for where to change database info. My queries work as of now. So i don't know why this is having issues. I found the /config/database.php and changed every username, password, db name, host to the correct things :

'mysql' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST', '192.168.10.10'),
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'homestead'),
    'username' => env('DB_USERNAME', 'homestead'),
    'password' => env('DB_PASSWORD', 'secret'),
    'unix_socket' => env('DB_SOCKET', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
    'engine' => null,
],

'pgsql' => [
    'driver' => 'pgsql',
    'host' => env('DB_HOST', '192.168.10.10'),
    'port' => env('DB_PORT', '5432'),
    'database' => env('DB_DATABASE', 'homestead'),
    'username' => env('DB_USERNAME', 'homestead'),
    'password' => env('DB_PASSWORD', 'secret'),
    'charset' => 'utf8',
    'prefix' => '',
    'schema' => 'public',
    'sslmode' => 'prefer',
],

'sqlsrv' => [
    'driver' => 'sqlsrv',
    'host' => env('DB_HOST', '192.168.10.10'),
    'port' => env('DB_PORT', '1433'),
    'database' => env('DB_DATABASE', 'homestead'),
    'username' => env('DB_USERNAME', 'homestead'),
    'password' => env('DB_PASSWORD', 'secret'),
    'charset' => 'utf8',
    'prefix' => '',
],

But this, didn't really help. I did the command

vagrant reload --provision

to make sure that wasn't an issue. It is saying in the error message in the terminal

2
PDO::__construct("mysql:host= 127.0.0.1 ;port=3306;dbname=homestead", "homes tead", "secret", [])

---

127.0.0.1

---

When i clearly changed the host in the database.php file in the /config to 192.168.10.10, which works when trying to connect with phpstorm.

I am having a hard time learning laravel and i am confused on how to get this changed to 192.168.10.10. Can an experienced person or at least anyone try to tell me the right direction to help me find the variable $dsn to change the host being passed in it?

Any help is appreciated!

Answer 1

Try running php artisan cache:clear or php artisan config:clear

You might also have a .env file overriding it possibly.

Answer 2

尝试编辑根文件夹中的 .env 文件或根文件夹中的 .env.example 文件
