数据库设置密码后无法访问phpMyAdmin

Question

在我为 MySQL 设置密码后，phpMyAdmin 拒绝访问数据库并显示以下错误：

MySQL 说：

1045 - 用户“root”@“localhost”访问被拒绝（使用密码：NO）

我已经用谷歌搜索并试图弄乱配置文件，我尝试了一切，但无法想出解决方案。我什至浏览了Stack Overflow之前的问题，但那里的答案也没有改变情况。

这是我的 config.inc.php 文件：

<?php
/*
 * 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']             = 'root';
$cfg['Servers'][$i]['AllowNoPassword']      = true;

/* Server parameters */
$cfg['Servers'][$i]['host']             = 'localhost';
$cfg['Servers'][$i]['connect_type']     = 'tcp';
$cfg['Servers'][$i]['compress']         = false;
$cfg['Servers'][$i]['extension'] = 'mysql';
$cfg['Servers'][$i]['AllowNoPassword'] = false;

/* Select mysqli if your server has it */
$cfg['Servers'][$i]['extension'] = 'mysqli';

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

/* 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';

/*
 * End of servers configuration
 */

/*
 * Directories for saving/loading files from server
 */
$cfg['UploadDir']   = '';
$cfg['SaveDir']     = '';

$cfg['AllowAnywhereRecoding']       = true;
$cfg['DefaultCharset']              = 'utf-8';
$cfg['DefaultLang']                 = 'en-utf-8';
$cfg['DefaultConnectionCollation']  = 'utf8_general_ci';

$cfg['MySQLManualBase'] = 'http://dev.mysql.com/doc/refman/5.1/en';
$cfg['MySQLManualType'] = 'searchable';

Answer 1

以下是您应该为 phpmyadmin config.inc.php 文件编写的代码：

   <?php

          $i = 0;
          $i++;
          $cfg['Servers'][$i]['host'] = 'localhost';
          $cfg['Servers'][$i]['connect_type'] = 'tcp';
          $cfg['Servers'][$i]['auth_type'] = 'http';
          $cfg['Servers'][$i]['compress'] = false;
          $cfg['Servers'][$i]['extension'] = 'mysql';
          $cfg['Servers'][$i]['AllowNoPassword'] = false;

   ?>

如果您遇到主机配置问题，您应该使用：

         $cfg['Servers'][$i]['host'] = '127.0.0.1';

如果这不起作用，这里有另一个不需要任何编码的解决方法：

• 在浏览器中打开 PHPMyAdmin 文件夹下的 /scripts/signon.php 页面，
• 输入登录详细信息
• 然后弹出另一个登录屏幕，输入 mysql 详细信息

Answer 2

1）进入目录C:\xampp\phpMyAdmin，打开文件config.inc.php

2）然后找到第21行，将其更改为（123456是我的mysql root密码）

$cfg['Servers'][$i]['password'] = '123456';

3）然后找到第34行，并将其更改 4)保存

$cfg['Servers'][$i]['controlpass'] = '123456';

文件。然后尝试刷新mysql页面。这在大多数情况下都必须有效..

Answer 3

你也可以尝试这个..
将您的密码字段留空

<?php
/*
* 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'] = 'en';

/* Bind to the localhost ipv4 address and tcp */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$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';

/*
* End of servers configuration
*/
?>

Answer 4

另一种选择是，在 config.inc.php 中，将 auth_type 更改为 'cookie'

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

或者，您也可以将 auth_type 设置为 'http'

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

无论使用哪种方法，下次登录 phpmyadmin 时，它都会提示您输入用户名和密码。
