mysql使用者的相關資訊是儲存在mysql資料庫的user表

執行語句，修改密碼

UPDATE user SET password=PASSWORD('root') WHERE user='root';

找到phpMyadmin的配置檔案，即phpMyAdmin目錄下的config.inc.php

如下程式碼

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

修改為

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