phpMyAdmin允许空密码登录的配置方法

当你将phpmyadmin登录密码设置为空密码时,尽管你通过Mysql命令行方式可以以空密码进入Mysql,但是当你重新以空密码登录phpmyadmin时却无法登陆。

这是因为默认phpmyadmin空密码登录是被禁止的,如果想要phpmyadmin空密码允许登录,就需要修改phpmyadmin相关配置。

如果想要允许phpmyadmin以空密码方式登录,就要修改libraries/config.default.php配置文件(如果你是以根目录下config.inc.php配安装phpmyadmin的,请一并检查)。

默认phpmyadmin空密码登录是被禁止的,这一行为主要通过配置文件libraries/config.default.php中的两个全局变量控制,即:

$cfg['Servers'][$i]['nopassword'] = false; $cfg['Servers'][$i]['AllowNoPassword'] = false;  
Copy after login

只要修改这两个变量,设定为True,phpmyadmin就会允许以空密码方式登录,即修改libraries/config.default.php中的:

$cfg['Servers'][$i]['nopassword'] = true; $cfg['Servers'][$i]['AllowNoPassword'] = true;  
Copy after login

同时将:

$cfg['Servers'][$i]['password'] = '';  
Copy after login

设置数据库连接密码设为空密码,即告成功。

注意事项

在允许phpmyadmin空密码登录时,往往只修改:

$cfg['Servers'][$i]['AllowNoPassword'] = true;  
Copy after login

这是不对的,空密码登录phpmyadmin仍然登录不了的,必须以上三个配置变量都修改。

在修改完phpmyadmin配置文件config.default.php后,重新以空密码方式登录phpmyadmin有时仍无法登陆。

这是因为cookie原因造成的,你需要关闭原有的phpmyadmin登录窗口,重新打开一个新窗口,这时空密码登录就没问题了。
