以前开发我一直都是用的appserv,appserv的特点就是一键安装,安装的时候会要求用户输入mysql的root密码。今天我改用xampp作为我的开发环境,所以碰到了修改mysql默认空密码的问题。

我看了下网上所提供的一些帮助信息,搞的那么复杂,其实没必要,我这有简单的做法,其实本质上都是大同小异,下面说下我的方法:

因为安装xampp后的mysql默认密码为空,所以我们能登录到phpmyadmin,在浏览器地址上输入http://localhost/phpmyamdin进入到数据库控制面板,然后选择名称为mysql数据库,如图,可从中看出 user表中,root的两个用户的密码为空。

<br>

我们可以手动编辑上图数据库中的root用户的密码即可。点快速编辑,或者编辑都可以编辑密码,如密码:123456,则填写 “*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9” (引号除外)

编辑后如下图

<br>

如果想把密码改成别的,可以直接执行西面的SQL语句,把new_password改成自己的密码即可:

1

UPDATE user SET password=PASSWORD('new_password') WHERE user='root';

<br>

<br>

<br>

另外既然mysql的root用户密码已经修改了,那么phpmyadmin中的对应密码配置也要修改,找到配置文件,如我的是:<br>F:/xampp/phpMyAdmin/config.inc.php<br>找到如下代码

/* Authentication type and info */

$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';

$cfg['Servers'][$i]['password'] = '';

$cfg['Servers'][$i]['extension'] = 'mysql';

$cfg['Servers'][$i]['AllowNoPassword'] = true;

修改为

/* Authentication type and info */

$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';

$cfg['Servers'][$i]['password'] = '123456';

$cfg['Servers'][$i]['extension'] = 'mysql';

$cfg['Servers'][$i]['AllowNoPassword'] = true;

 

 

 

 

 

继续修改phpmyadmin本地登陆设置,F:/xampp/phpMyAdmin/config.inc.php<br>$cfg['Servers'][$i]['auth_type'] = 'config';

修改成

$cfg['Servers'][$i]['auth_type']= 'cookie';
