“SQLSTATE[HY000] [2002] No such file or directory”

问题:

I am getting the following error when I try to migrate a table in Laravel 5 using the "php artisan migrate" command:

'SQLSTATE[HY000] [2002] No such file or directory' in . . . /vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:47

My .env file includes the default settings as follows:

DB_HOST=localhost
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

My database.php file lists mysql as the default database connection, homestead is listed as the database in my homestead.yaml file, and homestead is one of the tables listed when I access mysql and use the show databases; command.

Any thoughts about what I might be doing wrong?

回答1:

try 127.0.0.1 instead of localhost in your .env file. It works for me :)

回答2:

Add mysql.sock path in database.php file like below example

'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',

Eample

'mysql' => [
        'driver' => 'mysql',
        'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '8889'),

This seems to be an issue with the socket file. Please let me know if this helps Starting with Zend Tutorial - Zend_DB_Adapter throws Exception: "SQLSTATE[HY000] [2002] No such file or directory"

Okay, this is might be a special case to me however I had this issue.

I moved my files from a Laragon based server to a mamp based server on a different machine. I had this error for days and I only received this error when running php artisan migrate and not when loading the page. When loading the page i received table not found which is understandable as the table isn't there.

After quite some time I just though of running composer update and then it fixed the error and worked for me. Not sure if this helps anyone but I came back to this post in case it somehow does.
