phpmyadmin提示mysqli_real_connect(): (HY000/2002): No such file or directory錯誤的解決辦法

phpmyadmin上傳到網站目錄后提示解決phpmyadmin mysqli_real_connect(): (HY000/2002): No such file or directory的錯誤，解決方法把phpmyadmin目錄中的配置文件config.sample.inc.php改成config.inc.php 
打開編輯config.inc.php 
找到： 
$cfg['Servers'][$i]['host'] = 'localhost'; 
改成： 
$cfg['Servers'][$i]['host'] = '127.0.0.1'; 
再次刷新頁面就不會出現mysqli_real_connect(): (HY000/2002): No such file or directory的錯誤提示了。
