Laravel Forge Can't Connect to MySQL through Socket

Question

I've just started using Laravel Forge, but I can't seem to login to MySQL after SSHing into the server. Each time I try:

mysql -uforge -p
Enter password: thepassword

I get this error:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

I've got my environment variables set using Forge, so it shouldn't be using the defaults:

DB_HOST=thehostip
DB_DATABASE=forge
DB_USERNAME=forge
DB_PASSWORD=theotherpassword

and I've left the database configuration as:

'default' => env('DB_CONNECTION', 'mysql'),


'connections' => [

    'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => env('DB_DATABASE', 'forge'),
        'username'  => env('DB_USERNAME', 'forge'),
        'password'  => env('DB_PASSWORD', ''),
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
    ],

    ...
],

Answer 1

Okay, the solution turned out to be that using 512MB server is just inadequate. After emailing Laravel Forge and explaining my issue it was suggested that updating to at least a 1GB server would solve the problem, and it did. Once I provisioned a 1GB server I could get into MySQL via SSH with no issues.
