phpMyAdmin 尝试连接到 MySQL 服务器，但服务器拒绝连接。您应该检查配置文件中的主机、用户名和密码

需要修改phpmyadmin的配置文件，让其连接到MySQL数据库，用记事本打开 config.inc.php 文件

 <?php
 
 /* Servers configuration */
 $i = 0;
 
 /* Server: localhost [1] */
 $i++;
 $cfg['Servers'][$i]['verbose'] = 'localhost';
 $cfg['Servers'][$i]['host'] = 'localhost';
 $cfg['Servers'][$i]['port'] = '3306';
 $cfg['Servers'][$i]['socket'] = '';
 $cfg['Servers'][$i]['connect_type'] = 'tcp';
 $cfg['Servers'][$i]['extension'] = 'mysqli';
 $cfg['Servers'][$i]['auth_type'] = 'config';
 $cfg['Servers'][$i]['user'] = 'root';
 $cfg['Servers'][$i]['password'] = '';
 $cfg['Servers'][$i]['AllowNoPassword'] = true;
 
 /* End of servers configuration */
 
 $cfg['DefaultLang'] = 'en-utf-8';
 $cfg['ServerDefault'] = 1;
 $cfg['UploadDir'] = '';
 $cfg['SaveDir'] = '';
 
 /* rajk - for blobstreaming */
 $cfg['Servers'][$i]['bs_garbage_threshold'] = 50;
 $cfg['Servers'][$i]['bs_repository_threshold'] = '32M';
 $cfg['Servers'][$i]['bs_temp_blob_timeout'] = 600;
