访问被拒绝用户'root'@'localhost'（使用密码：是）

Question

我正在使用WAMP服务器进行android注册页面开发。我得到这个错误：

Access denied for user 'root'@'localhost' (using password: YES)

请帮我解决这个问题。

这里是我的config.inc.php文件：

<?php 
/* vim: set expandtab sw=4 ts=4 sts=4: */ 
/** 
* phpMyAdmin sample configuration, you can use it as base for 
* manual configuration. For easier setup you can use setup/ 
* 
* All directives are explained in documentation in the doc/ folder 
* or at <http://docs.phpmyadmin.net/>. 
* 
* @package PhpMyAdmin 
*/ 

/* 
* This is needed for cookie based authentication to encrypt password in 
* cookie 
*/ 
$cfg['blowfish_secret'] = 'a8b7c6d'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */ 

/* 
* Servers configuration 
*/ 
$i = 0; 

/* 
* First server 
*/ 
$i++; 
/* Authentication type */ 
$cfg['Servers'][$i]['verbose'] = 'mysql wampserver'; 
//$cfg['Servers'][$i]['auth_type'] = 'cookie'; 
$cfg['Servers'][$i]['auth_type'] = 'config'; 
$cfg['Servers'][$i]['user'] = 'root'; 
$cfg['Servers'][$i]['password'] = ''; 
/* Server parameters */ 
$cfg['Servers'][$i]['host'] = '127.0.0.1'; 
$cfg['Servers'][$i]['connect_type'] = 'tcp'; 
$cfg['Servers'][$i]['compress'] = false; 
/* Select mysql if your server does not have mysqli */ 
$cfg['Servers'][$i]['extension'] = 'mysqli'; 
$cfg['Servers'][$i]['AllowNoPassword'] = true; 



/* 
* phpMyAdmin configuration storage settings. 
*/ 

// No warning on pmadb tables 
$cfg['PmaNoRelation_DisableWarning'] = true; 


?> 

这里是config.php文件：

<?php 

/** 
* Database config variables 
*/ 
define("DB_HOST", "localhost"); 
define("DB_USER", "root"); 
define("DB_PASSWORD", "root"); 
define("DB_DATABASE", "android_api"); 
?> 

这里是我的确切问题： enter image description here

Answer 1

除非你已经为root用户标识添加了密码，然后默认情况下它不带密码出现。

所以只要把

define("DB_USER", "root"); 
define("DB_PASSWORD", ""); 

或只保留密码字段中phpMyAdmin的空白，并击中GO按钮

回复：您的评论：我使用phpMyAdmin

这时屏幕应该看起来像这样

用户名输入root并保留password:场空

然后按下GO按钮
