PHPMyadmin配置文件config.inc.php内容如下，在需要设置的地方增加了相关注释。

非常适合对数据库操作命令不熟悉的数据库管理者，下面我就说下怎么安装该工具：

1.先到网上下载phpmyadmin，再解压到可以访问的web目录下(如果是虚拟空间，可以解压后通过ftp等上传到web目录下)，当然您可以修改解压后该文件的名称。

2.配置config文件

打开libraries下的config.default.php文件，依次找到下面各项，按照说明配置即可：

A.访问网址

引用:

$cfg['PmaAbsoluteUri'] = '';这里填写phpmyadmin的访问网址

B.mysql主机信息

引用:

$cfg['Servers'][$i]['host'] = 'localhost'; // MySQL hostname or IP address

填写localhost或mysql所在服务器的ip地址，如果mysql和该phpmyadmin在同一服务器，则按默认localhost

$cfg['Servers'][$i]['port'] = ''; // MySQL port - leave blank for default port

mysql端口，如果是默认3306，保留为空即可

C.mysql用户名和密码

引用:

$cfg['Servers'][$i]['user'] = 'root'; // MySQL user 访问phpmyadmin使用的mysql用户名

fg['Servers'][$i]['password'] = ''; // MySQL password (only needed对应上述mysql用户名的密码

D.认证方法引用:

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

在此有四种模式可供选择，cookie，http，HTTP，config

config方式即输入phpmyadmin的访问网址即可直接进入，无需输入用户名和密码，是不安全的，不推荐使用。

当该项设置为cookie，http或HTTP时，登录phpmyadmin需要数据用户名和密码进行验证，,具体如下：

PHP安装模式为Apache，可以使用http和cookie；

PHP安装模式为CGI，可以使用cookie

E.短语密码(blowfish_secret)的设置

引用:

$cfg['blowfish_secret'] = '';

如果认证方法设置为cookie，就需要设置短语密码，置于设置为什么密码，由您自己决定 ，但是不能留空，否则会在登录phpmyadmin时提示错误

好了，到此为止，您已经成功安装了phpmyadmin，简单吧 ，赶快登录体验下吧

说明：

该文档说明的只是安装phpmyadmin的基本配置，关于config.default.php文件中各个配置参数的详细说明可以

phpMyAdmin 就是一种 MySQL 数据库的管理工具，安装该工具后，即可以通过 web 形式直接管理 MySQL 数据，而不需要通过执行系统命令来管理，非常适合对数据库操作命令不熟悉的数据库管理者，下面详细说明该工具的安装方法。

一、下载1、先到官方站点下载phpMyAdmin 安装包：http://www.phpmyadmin.net/ (安装包含各种语言all-languages)

2、再解压到 web 可以访问的目录下，如果是虚拟空间，可以解压后通过 ftp 工具上传到 web 目录下，同时您可以修改解压后该文件的名称(你可以自定义目录名称)。

二、配置3、打开 /libraries/config.default.php文件(旧版本是根目录下的config.inc.php文件)，用写字板(不要用记事本，这是UTF8编码)进行编辑，按照说明配置即可。

4、查找 $cfg['PmaAbsoluteUri']=‘'; // 修改为你将上传到空间的phpMyAdmin的网址

如：$cfg['PmaAbsoluteUri'] =‘http: // 网站域名/phpmyadmin/';

5、查找 $cfg['Servers'][$i]['host'] =‘localhost'; // 通常用默认，也有例外，可以不用修改

6、查找 $cfg['Servers'][$i]['auth_type'] =‘config'; // 在自己的机子里调试用config；如果在网络上的空间用cookie.

在此有四种模式可供选择：cookie，http，HTTP，config

① config 方式即输入phpMyAdmin 的访问网址即可直接进入，无需输入用户名和密码，是不安全的，不推荐使用。

② 设置cookie，http，HTTP方式，登录 phpMyAdmin 需要数据用户名和密码进行验证。

具体如下：PHP 安装模式为 Apache，可以使用 http 和 cookie；PHP 安装模式为 CGI，可以使用 cookie。

7、查找 $cfg['Servers'][$i]['user'] = ‘root'; // MySQL用户名

8、查找 $cfg['Servers'][$i]['password'] =''; // MySQL 密码 (only needed 留空就可以了)

9、查找 $cfg['Servers'][$i]['only_db'] = ''; // 你只有一个数据就设置一下,设置为你的数据库名；如果你想架设服务器，那么建议留空

10、查找 $cfg['DefaultLang'] = ‘zh'; // 这里是选择语言，zh代表简体中文的意思

11、查找$cfg['blowfish_secret'] =''; // 如果认证方法设置为cookie，就需要设置短语密码，设置为什么密码，由您自己决定，这里不能留空，否则会在登录 phpMyAdmin 时提示如下图所示的错误。

12、设置完毕后保存，现在可以上传到网络空间上了，浏览http://网站域名/phpmyadmin/测试一下。(输入数据库的用户名及密码就可以了)

如果要安装过程中出现：“phpMyAdmin - 错误 缺少 mysqli 扩展。请检查 PHP 配置。”错误。

解决方法如下：

①到phpmyadmin文件夹的\libraries\config.default.php文件中找：$cfg['Servers'][$i]['extension']='mysql';语句。

②如果有找到$cfg['Servers'][$i]['extension']='mysql';这句，就继续查找下面这句$cfg['Servers'][$i]['extension']='mysqli'; 并把其的注释去掉。

③如果没有找到$cfg['Servers'][$i]['extension']='mysql';这句，就把$cfg['Servers'][$i]['extension']='mysqli';语句，改成$cfg['Servers'][$i]['extension']='mysql'; 语句。(即确保 " mysql " 值能生效)
