How to Install PHPMyAdmin on the Raspberry Pi?

Benefits of Installing PHPMyAdmin on the Raspberry Pi

There are several advantages to installing PHPMyAdmin on a Raspberry Pi:

  • Provides a user-friendly web interface to manage MySQL databases instead of using the command line
  • Useful for web development projects that require a database backend
  • Allows centralized access to databases stored on the Raspberry Pi from other devices on the local network
  • Free and open-source tool with an active developer community

Prerequisites

Before installing PHPMyAdmin, you’ll need:

  • A Raspberry Pi model with network connectivity
  • Raspbian (or another Linux distribution) installed on the Raspberry Pi
  • Apache web server installed on the Raspberry Pi
  • MySQL database server installed on the Raspberry Pi
  • Basic Linux command line knowledge

I’ll provide commands and steps for Raspbian based on the latest version of Raspbian Stretch.

Installing the LAMP Stack

PHPMyAdmin requires a LAMP (Linux, Apache, MySQL, PHP) stack to run. Here are quick steps to get LAMP installed:

  1. Update apt repositories

    bash

sudo apt update

sudo apt upgrade

Install Apache, MySQL, and PHP

bash

sudo apt install apache2 mysql-server php libapache2-mod-php php-mysql

Enable Apache modules

bash

sudo a2enmod rewrite

sudo systemctl restart apache2

Secure the MySQL installation

bash

  1. sudo mysql_secure_installation

Follow the prompts to remove anonymous users, disable remote root login, and set a root password.

Downloading and Configuring PHPMyAdmin

With the LAMP stack set up, we can now install PHPMyAdmin:

  1. Install PHPMyAdmin and its dependencies

    bash

sudo apt install phpmyadmin php-mbstring php-zip php-gd php-json php-curl

Configure Apache to use PHPMyAdmin

bash

sudo phpenmod mbstring

sudo systemctl restart apache2

Secure PHPMyAdmin with an authentication method

bash

sudo nano /etc/phpmyadmin/config.inc.php

Under the Authentication Type section, uncomment and configure either the cookie or http auth option to enable user login.

Optionally create a symbolic link

bash

  1. sudo ln -s /usr/share/phpmyadmin /var/www/html

    This will allow accessing PHPMyAdmin directly at your Pi’s IP address.

You can now access the PHPMyAdmin interface in a web browser at http://your_pi_ip/phpmyadmin. Use your MySQL credentials to log in and manage databases.

Securing PHPMyAdmin

Since PHPMyAdmin provides full access to your MySQL server, it’s very important to secure it. Here are some tips:

  • Set up Apache HTTP authentication or cookie authentication in config.inc.php.
  • Create a strong username/password auth credential if using HTTP auth.
  • Disable remote MySQL root login privileges and create limited user accounts for web applications.
  • Use SSH tunneling or VPN instead of opening PHPMyAdmin ports in the firewall.
  • Install security monitoring tools like fail2ban on your Raspberry Pi.

Conclusion

Installing PHPMyAdmin is an easy way to get a web-based interface for MySQL administration on your Raspberry Pi. It allows you to simplify database management for web applications.

Just be sure to take precautions to properly secure PHPMyAdmin. Limit network exposure, create restricted user accounts for web apps, and consider tunneling traffic to PHPMyAdmin.

With a properly configured LAMP stack and some good security practices, you’ll have a solid environment for creating database-backed apps on your Raspberry Pi.

 Frequently Asked Questions 

  1. What is the default username and password to log in to PHPMyAdmin?
    The default username is “root” and there is no password set. It’s highly recommended to choose a strong password during the MySQL installation process for better security.

  2. Where are PHPMyAdmin databases stored on the Raspberry Pi?
    Database files created using PHPMyAdmin are stored in the standard MySQL data directory, usually /var/lib/mysql/ on Raspbian.

  3. Can I access PHPMyAdmin databases from another computer?
    Yes, as long as the Raspberry Pi running PHPMyAdmin is connected to your local network. You would navigate to the Pi’s IP address followed by /phpmyadmin in the browser URL bar (like http://192.168.1.123/phpmyadmin).

  4. Does installing PHPMyAdmin impact Raspberry Pi performance?
    There is a small additional system resource demand running MySQL, Apache and PHP. But modern Raspberry Pi boards have sufficient performance headroom to run PHPMyAdmin without issues for light/moderate database workloads.

  5. Can I uninstall or remove PHPMyAdmin later?
    Yes, you can remove the phpmyadmin package using the standard sudo apt remove phpmyadmin command. This will uninstall PHPMyAdmin but won’t remove MySQL or impact existing databases.

  6. Can I backup my PHPMyAdmin databases?
    Yes! PHPMyAdmin makes database backups easy. You can export a database as a SQL file or other format. It’s also a good idea to setup regular MySQL backups to preserve data.

  7. Does PHPMyAdmin work on any Raspberry Pi models?
    PHPMyAdmin can be installed on any 40-pin GPIO Raspberry Pi model (A+/B+/2/3/4). Very old models like the Pi 1 with 26-pin GPIO won’t work. A Pi 4 handles PHPMyAdmin best.

  8. Can I manage SQLite databases with PHPMyAdmin?
    No, PHPMyAdmin only supports MySQL/MariaDB databases. Other tools like phpLiteAdmin allow web management of SQLite databases instead.

  9. Is PHPMyAdmin optimized for the Raspberry Pi platform?
    PHPMyAdmin is designed to work well on common web hosting platforms like Apache/Linux so it runs great on a Raspberry Pi. No special optimization is required, beyond tuning MySQL for best performance based on your workload.

  10. Can I make modifications/customizations to PHPMyAdmin’s interface?
    Yes, PHPMyAdmin is open source so you can modify scripts and stylesheets to customize the interface. You can also extend functionality with plugins.

  11. Does PHPMyAdmin support managing users/privileges?
    Absolutely! Granting users access to specific databases or tables and setting privileges is a core function of PHPMyAdmin. This allows secure database access control.

  12. How do I change which database I am viewing in PHPMyAdmin?
    Use the navigation links at the top of the screen. Click on a database name to change the context to that database. You can also use the dropdown menu to switch.

  13. Can I import and export databases with PHPMyAdmin on a Raspberry Pi?
    Yes, importing and exporting SQL database dumps or other structured data files is built into PHPMyAdmin for easy migration between databases and servers.
