How to Fix the \'mysqli_real_connect(): (HY000/2002): No Such File or Directory\' Error in PhpMyAdmin?

Error Encountered: mysqli_real_connect() Function Issue

In a predicament involving the mysqli_real_connect() function, users may encounter an error message stating, "mysqli_real_connect(): (HY000/2002): No such file or directory." This error generally signifies a connection establishment failure to the MySQL database.

Resolution:

To resolve this error, users need to modify the /etc/phpmyadmin/config.inc.php file and alter the hostname setting. Here's how it can be done:

1. Navigate to the /etc/phpmyadmin/config.inc.php file.
2. Look for the $cfg['Servers'][$i]['host'] configuration parameter.

3. Change the hostname from 'localhost' to '127.0.0.1'. The updated code should look like this:

   $cfg['Servers'][$i]['host'] = '127.0.0.1';

4. Save the changes to the configuration file.

Explanation:

The error occurs because PhpMyAdmin initially attempts to connect to the MySQL database using the MySQL socket when 'localhost' is specified as the hostname. This connection method may not be supported on all systems, particularly on MacOS. By changing the hostname to '127.0.0.1', PhpMyAdmin will establish a TCP connection to the database instead, which should resolve the issue.
