Prerequisites

Before you set up MariaDB on Android, ensure you have the following:

• An Android device with 1 GB of free storage.
• Termux installed from the Google Play Store or F-Droid.
• A stable internet connection.

Step 1: Install Termux

To get started with MariaDB on Android, you’ll need Termux. If you haven’t installed Termux yet, follow these steps:

1. Open the Google Play Store or F-Droid.
2. Search for Termux.
3. Install and open the app.

Termux gives you a Linux-like environment, which is perfect for installing and running MariaDB.

Step 2: Update Termux Packages

Updating the Termux packages ensures that everything runs smoothly when installing MariaDB. Run the following command to update Termux:

$ pkg update && pkg upgrade

Keeping your system up-to-date is a good practice when setting up MariaDB on Android.

Step 3: Install MariaDB

Now it’s time to install MariaDB on Android. In Termux, run the following command to install MariaDB:

$ pkg install mariadb

This will download and install MariaDB on your device, making it ready to initialize.

Step 4: Initialize the MariaDB Database

Before starting the server, you need to initialize the database. Run this command to prepare MariaDB for use:

$ mysql_install_db

This sets up the necessary files and data directories to run MariaDB on Android.

Step 5: Start the MariaDB Server

Once MariaDB is installed and initialized, start the server by running:

$ mysqld_safe --datadir=/data/data/com.termux/files/usr/var/lib/mysql

This command starts the MariaDB server on your Android device, enabling you to manage databases directly from your mobile.

Step 6: Secure the MariaDB Installation

Securing your MariaDB installation is an important step, especially if you plan on connecting to the server from other devices. To secure your MariaDB server, run:

$ mysql_secure_installation

This script helps you set a root password, remove anonymous users, disable remote root logins, and more. For users of MariaDB on Android, this step is essential for ensuring your server is safe.

Step 7: Log Into MariaDB

To start working with your MariaDB server, log into the database using the root user:

$ mysql -u root -p

After entering the password, you’ll have access to the MariaDB command-line interface, where you can manage databases, users, and more.

Step 8: Managing the MariaDB Server

Managing MariaDB on Android is simple. Here are a few essential commands for managing the server:

Start the server:

$ mysqld_safe --datadir=/data/data/com.termux/files/usr/var/lib/mysql

Stop the server:

$ mysqladmin -u root -p shutdown

Use these commands to ensure smooth operation when starting or stopping the server.

Step 9: Connecting Remotely (Optional)

If you want to connect to MariaDB on Android from another device, consider using tools like localtunnel or ngrok to expose your server. Here’s an example using localtunnel:

$ lt --port 3306

This allows you to connect to the MariaDB server on your Android device remotely.

Step 10: Best Practices for Securing MariaDB

Security is important, especially when running MariaDB on Android. Follow these best practices:

• Use strong passwords for all users.
• Disable remote root logins unless necessary.
• Regularly update your MariaDB installation.
• Backup your databases frequently to prevent data loss.

Conclusion

Setting up MariaDB on Android is a fantastic way to turn your mobile device into a powerful, portable database server. Whether you’re a developer testing database operations or a student learning how databases work, this guide equips you with everything you need to install, run, and manage MariaDB using Termux.
