Warning: mysqli_connect(): (HY000/2002): No such file or directory

This error message is indicating that there is a problem connecting to the MySQL server. The specific error is "No such file or directory," which means that the system is unable to find the file or directory specified in the connection string.

This error message may occur due to several reasons such as:

  • The MySQL server is not running or is not reachable.
  • The connection details (such as the host, username, and password) provided in the connection string are incorrect.
  • A firewall is blocking the connection to the MySQL server.
  • The PHP MySQLi extension is not installed or configured correctly.

You should troubleshoot by checking that the server is running and reachable, that the connection details are correct, and that any firewalls or security groups are configured to allow connections to the MySQL server. Also, make sure PHP MySQLi extension is installed and configured correctly.
