深入phpMyAdmin的安装与配置的详细步骤_PHP
phpmyadmin
phpmyadmin就是一种mysql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本地服务器的根目录下,如apache的www目录。
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,本人的目录是"127.0.0.1/phpMyAdmin/",这个根据自己实际解压的后的情况而定
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
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
$cfg['blowfish_secret'] = '';
如果认证方法设置为cookie,就需要设置短语密码。
缺少mysqli扩展 的解决方法:
1.检查php.ini ;extension=php_mysqli.dll是不是已经启用
2.检查php.ini extension_dir 地址是不是指向了php目录的ext目录下
3.检查lib_mysql.dll有没有拷贝到windows目录下
4.检查php安装目录ext目录下,php_mysqli.dll文件是不是存在
5.查看php详细页面,看看mysql和mysqli是不是已经启动
结合自己的情况,进行修改就可以了。比如,我本机就是因为第3个原因会报错。把MySQL\bin下面的lib_mySQL.dll放置到windows目录下就ok!
注意:本人的操作系统为win7.

The WordPress database is housed in a MySQL database that stores all website data and can be accessed through your hosting provider’s dashboard, FTP, or phpMyAdmin. The database name is related to the website URL or username, and access requires the use of database credentials, including name, username, password, and hostname, which are typically stored in the "wp-config.php" file.

The default username and password for PHPMyAdmin are root and empty. For security reasons, it is recommended to change the default password. Method to change password: 1. Log in to PHPMyAdmin; 2. Select "privileges"; 3. Enter the new password and save it. When you forget your password, you can reset it by stopping the MySQL service and editing the configuration file: 1. Add the skip-grant-tables line; 2. Log in to the MySQL command line and reset the root password; 3. Refresh the permission table; 4. Delete skip-grant-tables line, restart the MySQL service.

Steps to delete a data table in phpMyAdmin: Select the database and data table; click the "Action" tab; select the "Delete" option; confirm and perform the deletion operation.

Reasons and solutions for access denied by phpMyAdmin: Authentication failed: Check whether the username and password are correct. Server configuration error: adjust firewall settings and check whether the database port is correct. Permissions issue: Granting users access to the database. Session timeout: Refresh the browser page and reconnect. phpMyAdmin configuration error: Check the configuration file and file permissions to make sure the required Apache modules are enabled. Server issue: Wait for a while and try again or contact your hosting provider.

phpMyAdmin is susceptible to multiple vulnerabilities, including: 1. SQL injection vulnerability; 2. Cross-site scripting (XSS) vulnerability; 3. Remote code execution (RCE) vulnerability; 4. Local file inclusion (LFI) vulnerability; 5. Information disclosure Vulnerability; 6. Privilege escalation vulnerability.
