I am unable to connect to my MySQL in xampp I have this error:
MySQL said: Documentation
1045 - Access denied for user 'root'@'localhost' (using password: NO)

found a solution, in my config file I just changed
$cfg['Servers'][$i]['auth_type'] = 'config';
to
$cfg['Servers'][$i]['auth_type'] = 'HTTP';
回答2:
/* Authentication type and info */
$cfg['Servers'][$i]['password'] = '';<----your password
or
/* User for advanced features */
$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = '';
to
/* User for advanced features */
$cfg['Servers'][$i]['controluser'] = 'your user';
$cfg['Servers'][$i]['controlpass'] = 'your password';

Change the value of
$cfg['Servers'][$i]['user'] = 'groot';
$cfg['Servers'][$i]['password']='groot';
in your ~/xampp/phpMyAdmin/config.inc.php
Here my username is groot and password is groot.
At the time of writing this answer, I had this issue and i fixed it by looking up your question.
回答4:
You need to modify the config-db.php and set your password to the password you gave to the user root, or else if he has no password leave as this ''.
回答5:
You may had set different passwords for user 'root' or have been changed your password. I had same error as :
mysqli_real_connect(): (HY000/1045): Access denied for user 'root'@'localhost' (using password: YES)
and I found that my root password for phpmyAdmin is not same on both 'mysql' and 'phpmyadmin' databases, so I updated my password for 'phpmyadmin' database same as 'mysql' database as follow:
sudo gedit /etc/phpmyadmin/config-db.php
and update the fields
$dbuser='root';
$dbpass='myNewPassword'; <-- update your new password here
Best wishes!

Follow these steps- 1.go to config.inc.php file and find - $cfg['Servers'][$i]['auth_type']
2.change the value of $cfg['Servers'][$i]['auth_type'] to 'cookie' or 'http'.
3.find $cfg['Servers'][$i]['AllowNoPassword'] and change it's value to true.
Now whenever you want to login, enter root as your username,skip the password and go ahead pressing the submit button..
Note- if you choose authentication type as cookie then whenever you will close the browser and reopen it ,again you have to login.
回答7:
$cfg['Servers'][$i]['auth_type'] = 'HTTP';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '1234';
This solves my problem too. It just logs in automatically.
回答8:
Edit the file xampp/mysql/bin/my.ini
Add
skip-grant-tables
under [mysqld]
回答9:
Just do what the message is asking for, create the user pma@localhost in the phpMyAdmin panel with no password
回答10:
In case none of the aforementioned solutions works for you, then simply do the under changes. Change this
$cfg['Servers'][$i]['host'] = '127.0.0.1';
to
$cfg['Servers'][$i]['host'] = 'localhost';
and
$cfg['Servers'][$i]['auth_type'] = 'config';
to
$cfg['Servers'][$I]['auth_type'] ='cookies';
It works in my situation, possibly works on your situation also.

This is the Different Solution, Check if your Services are running correctly, if WAMP icon showing orange color, and 2 out of 3 services are running it's showing, then this solution will work . Root cause:
If in your system mysql was there, later you installed WAMP then again one MYSQL will install as WAMP package, default port for MYSQL is 3306 , So in both mysql the port will be 3306, which is a port conflict, So just change the port it will work fine. Steps to change the Port.
- Right click the WAMP icon.
- Chose Tool
- Change the port in Port used by MySql Section
回答12:
Go got XAMPP->mysql->bin->my.ini
open the file with an editor and add 'skip-grant-tables' after mysql.
