How to Fix 'PDOException SQLSTATE[HY000] [2002]: No Such File or Directory' When Connecting to a Remote MySQL Server?

PDOException SQLSTATE[HY000] [2002]: No Such File or Directory

When attempting to execute commands on a remote server, such as php artisan migrate or php artisan db:seed, users may encounter the error message:

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

This error typically indicates that the MySQL server is not running. However, if the server is confirmed to be operational, consider the following solutions:

For Laravel 4:

1. In the app/config/database.php file, change "host" from "localhost" to "127.0.0.1".

For Laravel 5 :

1. In the .env file, change "DB_HOST" from "localhost" to "127.0.0.1".

Additional Troubleshooting:
If these solutions fail to resolve the issue, consider the following:

• UNIX Socket vs. TCP: "Localhost" typically uses a UNIX socket, while "127.0.0.1" uses TCP. In certain scenarios, UNIX sockets may fail to locate the database, making TCP a more reliable option.
• Check Database Credentials: Ensure that the username and password provided in the database configuration file are correct.
• Firewall Settings: Verify that the firewall is not blocking connections to the MySQL server.
