/usr/share/phpmyadmin/config.inc.php" E212: Can't open file for writing

vi /usr/share/phpmyadmin/config.inc.php
[...]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]
保存之后报错"/usr/share/phpmyadmin/config.inc.php" E212: Can't open file for writing
如何解决，请指教（初学者）

你的配置文件没有写入的权限，先调整下权限。
