Detailed explanation of PHPMyadmin configuration

PHPMyadmin is a very easy-to-use database management interface, especially suitable for novices who are not familiar with database operation commands. PHPMyadmin also has many configuration items. Today we will explain the configuration file of PHPMyadmin in detail. You can also refer to the mysql database video tutorial: MySql Tutorial

phpmyadmin Quick Start Tutorial

The content of the PHPMyadmin configuration file config.inc.php is as follows, and relevant comments have been added where settings need to be made.

Let me tell you how to install this tool:

1. Download phpmyadmin

2. Configuration config file
Open the config.default.php file under libraries, find the following items in order, and configure them according to the instructions:

A. Visit the URL

$cfg['PmaAbsoluteUri'] = '';

Fill in the access URL of phpmyadmin here, such as: $cfg['PmaAbsoluteUri'] = 'http://your site/phpmyadmin/';

B.mysql host information

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

Fill in the ip address of localhost or the server where mysql is located. If mysql and the phpmyadmin are on the same server, press the default localhost

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

mysql port, if it is the default 3306, just leave it blank

C.mysql username and password

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

MySQL user MySQL username used to access phpmyadmin

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

MySQL password (only neededThe password corresponding to the above mysql user name

D. Authentication method

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

There are four modes available here Select: cookie, http, HTTP, config

01: The config method is to enter the access URL of phpmyadmin to enter directly without entering the user name and password. It is unsafe and not recommended.

02: When this item is set to cookie, http or HTTP, logging in to phpmyadmin requires a data username and password for verification.

The details are as follows:

PHP installation mode is Apache, you can use http and cookie;

PHP installation mode is CGI, you can use cookie

E. Phrase password (blowfish_secret) setting

$cfg['blowfish_secret'] = '';

If authenticated If the method is set to cookie, you need to set a phrase password. It is up to you to decide what password to set, but it cannot be left blank, otherwise an error will be prompted when logging in to phpmyadmin. Okay, that's it. phpmyadmin has been successfully installed. It’s easy. Log in and experience it.

Instructions: This document only explains the basic configuration of installing phpmyadmin. , for detailed descriptions of each configuration parameter in the config.default.php file, please see its English comments.

Detailed version: phpMyAdmin is a MySQL database management tool, install this tool After that, you can directly manage MySQL data through the web form without the need to execute system commands. It is very suitable for database managers who are not familiar with database operation commands. The installation method of this tool is explained in detail below.

1. Download

1. First go to the site to download the phpMyAdmin installation package: http://www.php.cn/xiazai/gongju/97 (the installation includes various Languages ​​all-languages)

2. Unzip it to a directory that can be accessed by the web. If it is a virtual space, you can decompress it and upload it to the web directory through the ftp tool. At the same time, you can modify the decompressed file. Name (you can customize the directory name).

2. Configuration

3. Open the

/libraries/config.default.php

file (the old version is config.inc in the root directory .php file)<p>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。</p> <p>4、查找<code> $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']='<span style="COLOR: #ff0000">mysqli</span>'; 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']='<span style="COLOR: #ff0000">mysqli</span>';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！
