How to Fix \'Connection for Controluser Failed\' Error in phpMyAdmin in XAMPP?

Resolving "Connection for controluser as defined in your configuration failed" with phpMyAdmin in XAMPP

When using XAMPP on Windows XP, you might encounter the error "Connection for controluser as defined in your configuration failed" in phpMyAdmin. This issue can often arise due to an incorrect configuration or missing information.

To resolve this problem, follow these steps:

1. Log in to phpMyAdmin as Root: Access phpMyAdmin in a browser and log in using the root user.
2. Create a New Database: Create a new database named "phpmyadmin" to store phpMyAdmin data.
3. Create a User: Create a new MySQL user named "pma" and set its "host" to "localhost" (or the IP address of your server). Assign the user a secure password and grant it full control over the "phpmyadmin" database.
4. Locate the SQL File: Navigate to the phpMyAdmin installation directory and locate the "sql" subdirectory.
5. Import the SQL File: Open the "create_tables.sql" file from the "sql" directory in a text editor. Copy and paste its contents into the SQL tab in phpMyAdmin. Execute the query to create the necessary tables in the "phpmyadmin" database.
6. Configure config.inc.php: Open the "config.inc.php" file in the phpMyAdmin installation directory. Add the following lines (or update existing settings if present):

<code class="php">$cfg['Servers'][1]['pmadb'] = 'phpmyadmin';
$cfg['Servers'][1]['controluser'] = 'pma';
$cfg['Servers'][1]['controlpass'] = '<yourpassword>';</yourpassword></code>

7. Update Control Table Information: Add the following lines to the "config.inc.php" file:

<code class="php">// List of control tables used by PMA
$cfg['Servers'][1]['bookmarktable'] = 'pma_bookmark';
$cfg['Servers'][1]['relation'] = 'pma_relation';
$cfg['Servers'][1]['userconfig'] = 'pma_userconfig';
$cfg['Servers'][1]['table_info'] = 'pma_table_info';
$cfg['Servers'][1]['column_info'] = 'pma_column_info';
$cfg['Servers'][1]['history'] = 'pma_history';
$cfg['Servers'][1]['recent'] = 'pma_recent';
$cfg['Servers'][1]['table_uiprefs'] = 'pma_table_uiprefs';
$cfg['Servers'][1]['tracking'] = 'pma_tracking';
$cfg['Servers'][1]['table_coords'] = 'pma_table_coords';
$cfg['Servers'][1]['pdf_pages'] = 'pma_pdf_pages';
$cfg['Servers'][1]['designer_coords'] = 'pma_designer_coords';</code>

8. Save and Log Out: Save the changes to "config.inc.php" and log out of phpMyAdmin.
9. Log Back In: Log back into phpMyAdmin as the "pma" user using the password you created earlier.

The error message should now be resolved. If the problem persists, verify that you have followed all the steps correctly and ensure that your MySQL server is running and accessible.
