转到文件夹C：\xampp\phpMyAdmin，int此文件夹中有一个文件“config.inc.php”。在Notepad++或Sublime Text或任何文本编辑器中打开此文件。
在此代码下面添加这2个代码：

$cfg['Servers'][$i]['auth_type'] = 'cookie';

添加以下代码：

$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;

重新启动你的XAMPP，它就会工作了
我的xampp配置代码如下：

<?php

/* Servers configuration */
$i = 0;

$cfg['blowfish_secret'] = 'a8b7c6d'; //What you want

/* Server: localhost [1] */
$i++;
$cfg['Servers'][$i]['verbose'] = 'Local Databases';
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';

// Hidden databases in PhpMyAdmin left panel
//$cfg['Servers'][$i]['hide_db'] = '(information_schema|mysql|performance_schema|sys)';

// Allow connection without password
$cfg['Servers'][$i]['AllowNoPassword'] = true;

// Suppress Warning about pmadb tables
$cfg['PmaNoRelation_DisableWarning'] = true;

// To have PRIMARY & INDEX in table structure export
//$cfg['Export']['sql_drop_table'] = true;
//$cfg['Export']['sql_if_not_exists'] = true;

$cfg['MySQLManualBase'] = 'http://dev.mysql.com/doc/refman/5.7/en/';
/* End of servers configuration */

?>

转到文件夹C:\xampp\phpMyAdmin，在此文件夹中有一个名为config.inc.php的文件。在Notepad++或Sublime Text或任何文本编辑器中打开此文件。如果您添加了任何密码，请在其中键入密码。例如，我的密码是mysql123，配置行必须是：

$cfg['Servers'][$i]['password'] = 'mysql123';
