Detailed explanation of PHPMyadmin configuration

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/"  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 

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！
