【问题描述】：

我使用 XAMPP 运行 phpMyAdmin，但它一直显示以下错误：

phpMyAdmin 尝试连接 mysql 服务器，但服务器拒绝连接。您应该检查配置中的主机、用户名和密码，并确保它们与 MySQL 服务器管理员提供的信息相对应。

看起来像这样：

这是我的 config.inc 脚本：

/*
 * This is needed for cookie based authentication to encrypt password in
 * cookie
 */
$cfg['blowfish_secret'] = 'xampp'; /* YOU SHOULD CHANGE THIS FOR A MORE SECURE COOKIE AUTH! */

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

/*
 * First server
 */
$i++;

/* Authentication type and info */
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;
$cfg['Lang'] = '';

/* Bind to the localhost ipv4 address and tcp */
$cfg['Servers'][$i]['host'] = 'localhost:3307';
$cfg['Servers'][$i]['connect_type'] = 'tcp';

/* User for advanced features */
$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = '';

/* Advanced phpMyAdmin features */
$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
$cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark';
$cfg['Servers'][$i]['relation'] = 'pma__relation';
$cfg['Servers'][$i]['table_info'] = 'pma__table_info';
$cfg['Servers'][$i]['table_coords'] = 'pma__table_coords';
$cfg['Servers'][$i]['pdf_pages'] = 'pma__pdf_pages';
$cfg['Servers'][$i]['column_info'] = 'pma__column_info';
$cfg['Servers'][$i]['history'] = 'pma__history';
$cfg['Servers'][$i]['designer_coords'] = 'pma__designer_coords';
$cfg['Servers'][$i]['tracking'] = 'pma__tracking';
$cfg['Servers'][$i]['userconfig'] = 'pma__userconfig';
$cfg['Servers'][$i]['recent'] = 'pma__recent';
$cfg['Servers'][$i]['table_uiprefs'] = 'pma__table_uiprefs';
$cfg['Servers'][$i]['users'] = 'pma__users';
$cfg['Servers'][$i]['usergroups'] = 'pma__usergroups';
$cfg['Servers'][$i]['navigationhiding'] = 'pma__navigationhiding';
$cfg['Servers'][$i]['savedsearches'] = 'pma__savedsearches';
$cfg['Servers'][$i]['central_columns'] = 'pma__central_columns';
$cfg['Servers'][$i]['designer_settings'] = 'pma__designer_settings';
$cfg['Servers'][$i]['export_templates'] = 'pma__export_templates';
$cfg['Servers'][$i]['favorite'] = 'pma__favorite';

/*
 * End of servers configuration
 */

?> ```

【参考方案1】：

(A) 对于您的情况，您使用 config 作为身份验证类型：

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

首先，请为phpmyadmin创建一个用户：

sudo mysql --user=root mysql -p

然后

CREATE USER 'phpmyadmin'@'localhost' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'phpmyadmin'@'localhost' WITH GRANT OPTION;

FLUSH PRIVILEGES;

然后，编辑 config.inc.php 文件。您可以在“C:\xampp\phpmyadmin”中找到它并更改：

$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = ''; 

到

$cfg['Servers'][$i]['user'] = 'phpmyadmin';
$cfg['Servers'][$i]['password']  = 'some_pass';

(B) 另一种方法（我认为更安全）是使用以下方法：

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

在这种情况下，phpmyadmin 会弹出一个框，要求您输入用户名和密码。

【讨论】：

如果我使用第一个解决方案，它会给我这个错误： mysqli::real_connect(): (HY000/1045): Access denied for user 'root'@'localhost' (using密码：是）

我修改了答案，请尝试（a）和（b）两种方法看看效果。谢谢
