PHP Artisan Migrate with MAMP and Unix Socket

问题:

I was developing my application originally in Laravel 4.2 but have since decided to move it to the 5.0 version so that it covers a lot more changes and strengths that 5.0 has over 4.2.

I am trying to run my migratiosn however I am getting the error:

[PDOException]
  SQLSTATE[HY000] [2002] No such file or directory

I looked into this and noticed how it is because I'm running MAMP for my server instead of vagrant and homestead. I'm not knocking the uses of those two but I at this point feel more comfortable with MAMP until it fails me. The reason I know its MAMP is because of needing to declare the unix socket value to be used.

Now on my 4.2 version of my application I have the following:

'mysql' => array(
    'driver'    => 'mysql',
    'unix_socket'   => '/Applications/MAMP/tmp/mysql/mysql.sock',
    'host'      => getenv('DB_HOST'),
    ...
),

With my Laravel 5.0 version I am making use of the .env file for my Environment variables and not sure how I need to do this so that it knows to use the unix socket value.

Cans someone clue me into how I should adopt this into the new version or a better way to add it into the settings so that I don't have to do that?

回答1:

Try this:

'mysql' => array(
'driver'    => 'mysql',
'unix_socket'   => getenv('UNIX_SOCKET'),
'host'      => getenv('DB_HOST'),
...
),

In .env add

UNIX_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

Thanks, help fix migration issue for me using:

MAMP PRO 4.2
Laravel 5.5

inside .env file:

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=<database name>
DB_USERNAME=<username - default root>
DB_PASSWORD=<password - default root>
DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

inside config/database.php:

'connections' => [

    'mysql' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', '<database name>'),
        'username' => env('DB_USERNAME', '<username - default root>'),
        'password' => env('DB_PASSWORD', '<password - default root>'),
        'unix_socket' => env('DB_SOCKET', '/Applications/MAMP/tmp/mysql/mysql.sock'),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
        'strict' => true,
        'engine' => null,
    ],
],

Also don't forget to add to app/Providers/AppServiceProviders.php:

use Illuminate\Support\Facades\Schema;
public function boot()
{
   Schema::defaultStringLength(191);
}

In laravel 5.5 the unix_socket changes to DB_SOCKET

inside .env file :

DB_USERNAME=root
DB_PASSWORD=root
DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

inside config/database.php:

    'mysql' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'unix_socket' => env('DB_SOCKET', ''),
