phpMyAdmin ERROR: mysqli_real_connect(): (HY000/1045): Access denied for user 'pma'@'localhost' (using password: NO)

Question

I keep getting the following errors with mysql connection through XAMPP and I don\'t know what to do:

That\'s the code in the config.inc.php

Answer 1

I experienced the same errors on a fresh install of VestaCP. I solved the issues by following the instructions on this video.

1. Go to phpmyadmin-fixer and run the appropriate command.
2. Restart Apache, NGINX and MySQL servers.
3. That's it!

Answer 2

I solved the problem by adding the line skip-grant-tables to the my.ini:

# The MySQL server
[mysqld]
skip-grant-tables
port= 3306
...

Under XAMPP Control Panel > Section "MySQL" > Config > my.ini

Answer 3

Add these lines to the file xampp\phpMyAdmin\config.inc:

$cfg['Servers'][$i]['controluser'] = 'root'; 
$cfg['Servers'][$i]['controlpass'] = '';

Answer 4

I am using UniServer Zero XIV 13.x.x UniController XIV V2.3.1:

From the command line I did this:

mysql> CREATE USER 'pmauser'@'%' IDENTIFIED BY 'MyPasswordHere!';
Query OK, 0 rows affected (0.07 sec)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'pmauser'@'%' WITH GRANT OPTION;
Query OK, 0 rows affected (0.02 sec)

Then I went to C:\...\wamp\ZeroXIV_unicontroller_2_3_1\UniServerZ\home\us_opt1\config.inc.php and modified the file to have this:

/* PMA User advanced features */
//////////$cfg['Servers'][$i]['controluser']    = 'pma';
//////////$cfg['Servers'][$i]['controlpass']    = $password;
$cfg['Servers'][$i]['controluser']    = 'pmauser';
$cfg['Servers'][$i]['controlpass']    = 'MyPasswordHere!';

I restarted Apache and MySQL. The error is gone!
