phpmyadmin提示mysqli_real_connect(): (HY000/2002): No such file or directory错误的解决办法

phpmyadmin上传到网站目录后提示解决phpmyadmin mysqli_real_connect(): (HY000/2002): No such file or directory的错误，解决方法把phpmyadmin目录中的配置文件config.sample.inc.php改成config.inc.php 
打开编辑config.inc.php 
找到： 
$cfg['Servers'][$i]['host'] = 'localhost'; 
改成： 
$cfg['Servers'][$i]['host'] = '127.0.0.1'; 
再次刷新页面就不会出现mysqli_real_connect(): (HY000/2002): No such file or directory的错误提示了。
