Why Am I Getting a '2002 No such file or directory' Error When Connecting to MySQL?

Addressing "2002 No such file or directory" Error in MySQL Connection

When establishing a MySQL connection, it's possible to encounter the error message "2002 No such file or directory." This issue stems from an incorrect socket path in the PHP configuration.

Several factors contribute to this error:

• Incorrect socket path in php.ini
• Invalid MySQL root password
• Missing MySQL service

To resolve this error, follow these steps:

1. Verify Socket Path:

   Check the mysql.default_socket variable in php.ini (php.ini in Mac OS X). The default value is /var/mysql/mysql.sock. If it's not set, set it to /tmp/mysql.sock.

2. Correct MySQL Root Password:

   If the incorrect MySQL root password is used, access will be denied. Ensure that the password is accurate.

3. Start MySQL Service:

   In some cases, the MySQL service may not be running. On Mac OS X, use the following command to start the service:

   sudo /usr/local/mysql/support-files/mysql.server start

4. Consider MySQL Address (Optional):

   In some cases, replacing localhost with 127.0.0.1 in the connection string has been known to resolve the issue. This is likely due to a misconfigured hosts file.
