【问题描述】：
昨天我的 MySQL 工作正常。今天我尝试访问它并收到上述错误。我从这里尝试了一些建议，但没有改变。不断获取'localhost'不允许连接..... 检查 config.inc.php 文件
/* 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'] = true;
$cfg['Lang'] = '';
/* Bind to the localhost ipv4 address and tcp */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
对我来说看起来不错，但我只是一个初学者
下面的错误日志对我来说毫无意义
