phpMyAdmin builds and manages multiple database servers
Environment description:
系统版本 CentOS 6.9 x86_64 软件版本 nginx-1.12.2 php-5.5.38 phpMyAdmin 4.8.0.1
1. Introduction to phpMyAdmin
phpMyAdmin is a PHP-based, Web-based -Base mode is a MySQL database management tool built on the website host, allowing administrators to use the Web interface to manage the MySQL database. This web interface can be a better way to input complex SQL syntax in a simple way, especially when it comes to importing and exporting large amounts of data. One of the greater advantages is that phpMyAdmin is executed on the web server like other PHP programs, but you can use the HTML pages generated by these programs anywhere, that is, to remotely manage the MySQL database, and easily create, modify, and delete Databases and data tables. You can also use phpMyAdmin to create commonly used PHP syntax to facilitate the correctness of SQL syntax required when writing web pages.

2. Environmental requirements for installing phpMyAdmin
3. Steps
3.1. Compile and install nginx and php. You can refer to the previous blog post. I will not go into details here. However, based on the environmental requirements of phpMyAdmin, the compilation parameters used when compiling php are:
./configure --prefix=/application/php5.5.38 --with-jpeg-dir=/usr/lib64 --with-freetype-dir=/usr/lib64/ --with-curl --enable-fpm --enable-mbstring --with-gd --with-fpm-user=nginx --with-fpm-group=nginx --with-mysqli=mysqlnd --with-mysql-sock=/tmp/mysql.sock --with-openssl --enable-zip
3.2. Configure phpMyAdmin
Put the downloaded phpmyadmin source code package into the nginx site root directory, that is, the html directory, unzip and modify the nginx configuration file, and rename the default phpMyAdmin configuration file cp config.sample.inc.php config.inc. php
3.3. Build the database and perform database creation authorization (refer to the previous blog post)
3.4. Browser access login
4 , Configure phpMyAdmin to manage multiple database servers
Take 10.0.0.51 and 10.0.0.52 as examples
4.1 Install mysql on 10.0.0.52
Set password and log in to mysql
[root@db02 mysql]# mysql -uroot -p123456
Authorize the database to 10.0.0.51
mysql> grant all on *.* to root@'10.0.0.51' identified by '123456';
4.2 Configure db01 with phpMyAdmin installed
vim /application/nginx/html/phpMyAdmin-4.8.0.1-all-languages/config.inc.php 复制粘贴并修改 $i++; /* Authentication type */ $cfg['Servers'][$i]['auth_type'] = 'cookie'; /* Server parameters */ $cfg['Servers'][$i]['host'] = '10.0.0.52'; $cfg['Servers'][$i]['compress'] = false; $cfg['Servers'][$i]['AllowNoPassword'] = false;
Refresh the page to log in to the 10.0.0.52 database.

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.
