拥有适用于Linux 5.6.12-0的XAMPP。当我启动Xammp时，它显示以下内容：

Starting XAMPP for Linux 5.6.12-0...
XAMPP: Starting Apache...ok.
XAMPP: Starting MySQL...ok.
XAMPP: Starting ProFTPD...ok.

但是当你去http://127.0.0.1/phpmyadmin/时，它会说：

 Cannot log in to the MySQL server
 Connection for controluser as defined in your configuration failed.

我的cinfig.inc.php：

由于您正在使用XAMPP软件包，因此应该由该安装程序配置，并且任何手动更改都可能与XAMPP软件包完成的一些幕后魔术冲突。

话虽如此，有些事情在这里毫无意义。

您的auth_type是＆＃39; cookie＆＃39;因此，登录时系统会提示您输入用户名和密码。根本不会使用$cfg['Servers'][$i]['user'] = 'brahim';和$cfg['Servers'][$i]['password'] = '';这两行，因此您可以安全地删除它们。这并不会直接影响您的登录能力，但会导致混淆密码的位置，并且我发现减少混淆的数量会更好。

您的问题是控制用户，行$cfg['Servers'][$i]['controluser'] = 'pma';和$cfg['Servers'][$i]['controlpass'] = '';将它们注释掉（在每行的开头放置一个//）片刻以暂时绕过高级配置特征。这应该允许您使用通常的MySQL用户名和密码登录。

我在你提到的评论中看到你不知道你的密码。默认情况下，MySQL附带用户名＆＃39; root＆＃39;和一个空密码。试试吧。如果它不起作用，您将不得不重置它。请参阅https://stackoverflow.com/a/18427124/2385479 - 至少在Windows上有一个XAMPP提供的实用程序来重置密码。我无法找到您在Linux上找到它的位置的任何参考，但请查看您的XAMPP安装文件夹。如果失败了，那么在{4}}或者它已经在Stackoverflow上得到了很多回答。通用指令是停止mysqld，再次使用--skip-grant-tables启动它，手动更改密码，然后正常重启mysqld - 但是你应该查看链接，因为大多数系统都有特定的说明。

此时，您可以正常使用phpMyAdmin，也可以继续恢复配置存储使用的高级功能。

无论如何，回到实际问题，一旦您成功登录，请检查是否有pma用户，以及是否只是更改了密码。如果没有，请使用MySQL manual has directions中的SQL语句创建一个：GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db>.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';。知道密码后，请修改config.inc.php并将其插入＆＃39; controlpass＆＃39;变量，取消注释＆＃39; controlpass＆＃39;和＆＃39; controluser＆＃39;然后再试一次。
