我安装了 Xampp（适用于 Windows）。我很高兴使用它的所有功能。
然后我想更改MySql密码。我设置了一个随机生成的密码（rCZ4Xnz78zbLY2Vh）。然后PHPMyAdmin停止登录。它开始给出以下错误消息，此后一直如此：
Error
MySQL said:
Cannot connect: invalid settings.
phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection.
You should check the host, username and password in your configuration and make sure that
they correspond to the information given by the administrator of the MySQL server.
然后我编辑了PHPMyAdmin的“config.inc.php”文件，其内容如下：
<?php
/* Servers configuration */
$i = 1;
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['port'] = '3306';
$cfg['Servers'][$i]['ssl'] = FALSE;
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysql';
$cfg['Servers'][$i]['compress'] = FALSE;
$cfg['Servers'][$i]['controluser'] = 'root';
$cfg['Servers'][$i]['controlpass'] = 'rCZ4Xnz78zbLY2Vh';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'rCZ4Xnz78zbLY2Vh';
$cfg['Servers'][$i]['nopassword'] = TRUE;
/* rajk - for blobstreaming */
$cfg['Servers'][$i]['bs_garbage_threshold'] = 50;
$cfg['Servers'][$i]['bs_repository_threshold'] = '32M';
$cfg['Servers'][$i]['bs_temp_blob_timeout'] = 600;
$cfg['Servers'][$i]['bs_temp_log_threshold'] = '32M';
/* Other settings */
$cfg['blowfish_secret'] = '';
$cfg['DefaultCharset'] = 'utf-8';
$cfg['UploadDir'] = '';
$cfg['SaveDir'] = '';
?>
但是我能够通过命令行使用相同的密码连接到 MySql 服务器。
C:\Users\hkBattousai>mysql.exe --user=root --password=rCZ4Xnz78zbLY2Vh
mysql.exe: Unknown OS character set 'cp857'.
mysql.exe: Switching to the default character set 'latin1'.

然后我通过命令行界面删除了密码：
我还从config.inc.php文件中删除了密码。该文件中的相关行现在是：
$cfg['Servers'][$i]['controluser'] = 'root';
$cfg['Servers'][$i]['controlpass'] = '';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
目前，这很奇怪，但是我可以用我删除的密码连接，但我不能用空密码连接：
C:\Users\hkBattousai>mysql.exe --user=root --password=rCZ4Xnz78zbLY2Vh // Connects
C:\Users\hkBattousai>mysql.exe --user=root --password= // Error given
我想为这个用户分配另一个随机密码，并且我想通过 PHPMyAdmin 访问我的数据库，就像我之前在全新的 Xampp 安装中所做的那样。我该怎么办？我真的很困惑，我需要你的帮助。
就像config.inc.php文件内容被忽略一样。我从模板文件中复制了它config.sample.inc.php并更改了它的内容。它现在位于目录中\Xampp\phpmyadmin\。
版本：
Xampp : 3.1.0
MySQL : 5.5.27
PHP : 5.4.7
Apache : 2.4
Windows : 7 Ultimate x64 SP1
