今日安装phpMyAdmin后进入phpMyAdmin管理页面，猛发现下面有这么几句红色的错误提示：

引用内容：
必须在您的配置文件中设定 $cfg['PmaAbsoluteUri'] 指令！
The mbstring PHP extension was not found and you seem to be
using multibyte charset.Without mbstring extension phpMyAdmin
is unable to split strings correctly and it may result in unexpected
results.
   

查找了整个百度，终于找到了解决的办法，加上对phpMyAdmin安装配置，总结如下：

1、将phpMyAdmin-2.6.2-rc1.zip解压到web根目录，如d:/www/phpmyadmin。

2、打开config.inc.php，查找$cfg['PmaAbsoluteUri'] =""，加上phpmyadmin所在路径，如：$cfg['PmaAbsoluteUri'] ="http://localhost/phpMyAdmin/"

3、查找
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';

分别填上你mysql的用户和密码即可，这里为
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '123456';

4、php.ini文件中";extension=php_mbstring.dll"前面的";"一定要去掉，同时将php/etx目录下的php_mbstring.dll文件复制到c:/winnt/system32目录下!

(第2和第4步是为了解决在打开phpmyadmin时下面出现的
“必须在您的配置文件中设定 $cfg['PmaAbsoluteUri'] 指令！
The mbstring PHP extension was not found and you seem to be using
multibyte charset. Without mbstring extension phpMyAdmin is unable
to split strings correctly and it may result in unexpected results.”
提示及其它相关的问题)

5、如非本地使用，最好加上验证!
查找$cfg['Servers'][$i]['auth_type'] = 'config',将config改为http即可，
如$cfg['Servers'][$i]['auth_type'] = 'http'

6、保存config.inc.php!
