When I checked out the Odroid N2+, I knew I had to get my hands on one. If you’re not familiar with the Odroid N2+, it’s a powerful and compact single board computer (SBC) that’s perfect for various projects, including setting up your own web server. Today, I will take you through a step-by-step guide on setting up a web server with the Odroid N2+. Trust me, it’s easier than you think!

Setting Up a Web Server with the Odroid N2+

Step 1: Gather the Hardware

Before we dive into the process, let’s first gather the necessary hardware:

  • Odroid N2+ board (I’m using the 4GB RAM model, but there’s also a 2GB RAM option)
  • 5V/4A power supply
  • 16GB or larger microSD card (I recommend a class 10 or higher for better performance)
  • USB keyboard and mouse
  • HDMI cable and monitor
  • Ethernet cable (optional but recommended for reliable connectivity)

Step 2: Install an Operating System

To get started, we need to install an operating system (OS) on the Odroid N2+. I chose Ubuntu Mate 20.04 as my OS because it’s user-friendly, and I’ve always been a fan of the Ubuntu ecosystem. Feel free to use any other OS compatible with the N2+ if you prefer.

  • Download the Ubuntu Mate 20.04 image for the Odroid N2+ from the official website (https://odroid.in/ubuntu_20.04lts/).
  • Use a software like Etcher to flash the image onto the microSD card.
  • Insert the microSD card into the Odroid N2+.
  • Connect the HDMI cable, keyboard, mouse, and Ethernet cable (if using) to the N2+.
  • Plug in the power supply to turn on the device and complete the setup process.

Step 3: Update the System

Once the OS is up and running, it’s a good practice to update the system. Open the terminal and type the following commands:

sudo apt update
sudo apt upgrade

This process might take some time, depending on your internet connection. So, grab a cup of coffee while you wait. I know I did!

Step 4: Install and Configure the Web Server

For this project, we’re going to use the Apache web server. It’s a popular choice because it’s open-source, powerful, and easy to configure. Install Apache using the following command:

sudo apt install apache2

Once installed, enable and start the Apache service:

sudo systemctl enable apache2
sudo systemctl start apache2

Now, open your web browser and type in the Odroid N2+’s IP address. If everything is set up correctly, you should see the Apache default welcome page. Congrats! You now have a working web server.

Step 5: Install PHP and MySQL

To make our web server more versatile, let’s install PHP and MySQL. This will allow us to host dynamic websites and applications. Run the following command:

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

After installation, restart the Apache service:

sudo systemctl restart apache2

And that’s it! You’ve successfully set up a web server with the Odroid N2+. From here, you can customize the server as needed, upload your website files, or create databases for your applications. But let’s not stop there. I’ll share a few additional tips that I found helpful while working with my Odroid N2+ web server.

Step 6: Configure the Firewall

For added security, it’s important to configure the firewall to allow incoming traffic to the web server. Ubuntu comes with the Uncomplicated Firewall (UFW) by default. Enable it and allow incoming HTTP and HTTPS traffic:

sudo ufw enable
sudo ufw allow http
sudo ufw allow https

Step 7: Set Up FTP Access

To easily manage your web server files, I recommend setting up FTP access. We’ll use the popular and secure FTP server, vsftpd. Install and configure it with the following commands:

sudo apt install vsftpd
sudo nano /etc/vsftpd.conf

Edit the configuration file with the following changes:


Save the file and restart the vsftpd service:

sudo systemctl restart vsftpd

Now, you can access your web server files using an FTP client like FileZilla.

Step 8: Monitor and Optimize Performance

It’s essential to keep an eye on your server’s performance to ensure it’s running smoothly. Install htop, a handy terminal-based system monitoring tool:

sudo apt install htop

To run htop, simply type htop in the terminal.

Additionally, consider using a caching system like Redis to optimize your web server’s performance. Install Redis by running:

sudo apt install redis-server

Common Troubleshooting Tips for Your Odroid N2+ Web Server

In any tech project, there’s a possibility you’ll encounter issues along the way. Here’s a list of common problems and their solutions when setting up an Odroid N2+ web server:

Apache not displaying the default welcome page

If you don’t see the Apache default welcome page after completing Step 4, try the following:

Check that the Apache service is running using the command: sudo systemctl status apache2
If it’s not running, restart the service with:

sudo systemctl restart apache2

Ensure your Odroid N2+ is connected to the internet and that the correct IP address is being used.

Unable to install packages or updates

If you can’t install packages or updates, it could be due to a problem with your internet connection or software repositories. Try these solutions:

Confirm that your Odroid N2+ is connected to the internet.
Check and update your software repositories in /etc/apt/sources.list.
Run the update command to refresh the package list before attempting to install or update packages.

sudo apt update

Permission issues with the web server

If you encounter permission issues while trying to upload or modify files in the web server directory, try the following:

Check the owner and group permissions of the web server directory using:

 ls -la /var/www/html

Change the owner and group of the directory to the appropriate user and group using:

 sudo chown -R user:group /var/www/html

Set the correct permissions for the directory using:

 sudo chmod -R 755 /var/www/html

FTP connection issues

If you’re unable to connect to your web server using FTP, consider the following solutions:

Verify that the vsftpd service is running using:

 sudo systemctl status vsftpd

If it’s not running, restart the service with:

 sudo systemctl restart vsftpd

Confirm that the Odroid N2+ firewall allows FTP traffic by checking the UFW rules with:

 sudo ufw status

Ensure your FTP client is configured with the correct IP address, username, and password.

MySQL connection problems

If you’re having trouble connecting to MySQL, try these steps:

Check that the MySQL service is running with:

 sudo systemctl status mysql

If it’s not running, start the service using:

 sudo systemctl start mysql

Verify that your MySQL user has the appropriate privileges by logging into the MySQL command prompt and running SHOW GRANTS FOR ‘username’@’localhost’;.

Wrapping Up

Setting up a web server with the Odroid N2+ was not only a fantastic learning experience, but it also allowed me to appreciate the capabilities of this small yet powerful single board computer. As someone who enjoys hands-on projects, I found that working with the Odroid N2+ was both challenging and satisfying. The compact size and flexibility of the N2+ make it an excellent choice for DIY enthusiasts, whether you’re building a web server, media center, or even a home automation system.

Throughout this project, I found that the Odroid N2+ is more than capable of handling a web server, even with its small form factor. I hope that this guide has inspired you to explore the world of single board computers and perhaps even set up your own Odroid N2+ web server.
