详解PHPMyadmin的配置
phpmyadmin快速入门教程
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。
下面我就说下怎么安装该工具:
1. phpmyadmin下载
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
$cfg['PmaAbsoluteUri'] = '';
这里填写phpmyadmin的访问网址,如:$cfg['PmaAbsoluteUri'] = 'http://你的站点/phpmyadmin/';
B.mysql主机信息
$cfg['Servers'][$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
$cfg['Servers'][$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
$cfg['Servers'][$i]['auth_type'] = 'cookie';
在此有四种模式可供选择:cookie,http,HTTP,config
01: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。
02: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
$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看其英文注释。

详解版:
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、先到站点下载phpMyAdmin 安装包:http://www.php.cn/xiazai/gongju/97(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)
三:常见问题
1. 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)

2. 在日常开发中,有的人可能会不小心将我们www下的phpmyadmin给删除了,这时我们再通http://localhost/phpMyAdmin/访问我们的数据库就没办法访问了,页面会提示Not Found了,也就是文件不存在,我们已经删除了phpmyadmin怎么会存在呢?对吧!
第一步:
我们可以到phpmyadmin的官网来下载phpmyadmin进行安装
地址:https://www.phpmyadmin.net/
那么我们如何来重新下载安装呢?
第二步:
将解压到C盘根目录下,重命名为phpMyAdmin,进入该文件夹,找到config.sample.inc.php,改名为config.inc.php,编辑器打开改文件。找到下列代码
$cfg['blowfish_secret'] = ''
改为
$cfg['blowfish_secret'] = 'c4ca4238a0b923820dcc509a6f75849b';
//一个长字符串密码就行
保存退出
第三步:
进入到环境中的apache的conf文件夹下,新建一个phpmyadmin.conf文件,代码编辑器打开,加入下列代码:
Alias /phpmyadmin "c:/phpMyAdmin/" <Directory "c:/phpMyAdmin/"> Options Indexes FollowSymLinks MultiViews AllowOverride all Require all granted php_admin_value upload_max_filesize 128M php_admin_value post_max_size 128M php_admin_value max_execution_time 360 php_admin_value max_input_time 360 </Directory>
保存退出
第四步:
在该文件夹内找到配置文件httdp.conf,用文本编辑器打开,在末尾增加一行以下代码:
Include conf/phpmyadmin.conf
保存退出
第五步:最后一步将apache重启一下
这个时候我们再来访问http://localhost/phpmyadmin/
已经恢复正常了!
