The native tool for access MySQL or MariaDB databases is the command-line.
With a few commands, you can access the database shell and perform a variety of tasks including viewing and creating databases and database users.
However, not everyone is a fan of the command-line, and this is where phpMyAdmin is beneficial.
Written in PHP, phpMyAdmin is a wonderful free and open-source tool that provides a front-end web interface to MySQL or MariaDB.
It allows users to log in and easily perform database management tasks such as managing databases, users, and permissions to mention a few.
Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform related phpMyAdmin queries.
In this context, we shall look into the installation of phpMyAdmin on Ubuntu.
Common php package:
1. php-mbstring: A module for managing non-ASCII strings and convert strings to different encodings
2. php-zip: This extension supports uploading .zip files to phpMyAdmin
3. php-gd: Enables support for the GD Graphics Library
4. php-json: Provides PHP with support for JSON serialization
5. php-curl: Allows PHP to interact with different kinds of servers using different protocols
Run the following command to install these packages onto your system:
# sudo apt install phpmyadmin php-mbstring php-zip php-gd php-json php-curl
