What You’ll Need
Hardware
The Raspberry Pi 3 Model B+ is a capable single-board computer featuring a 1.4GHz quad-core ARM Cortex-A53 processor, 1GB RAM, dual-band 2.4GHz and 5GHz wireless LAN, Bluetooth 4.2/BLE, and Gigabit Ethernet. It has 4 USB 2.0 ports, a 40-pin GPIO header, HDMI, camera and display interfaces. Optional accessories include a power supply, microSD card, and case for a complete setup.
Software
To set up Nextcloud on your Raspberry Pi 3, you’ll need a compatible operating system like Raspberry Pi OS (previously Raspbian) or Ubuntu Server. Ensure you have the latest stable version installed. Nextcloud requires a web server (Apache or Nginx), PHP 7.3 or higher, and a database (MySQL/MariaDB or PostgreSQL). Make sure your Pi has enough storage capacity to accommodate your Nextcloud data.
Step-by-Step Setup Guide
Installing the Operating System
To install the operating system on your Raspberry Pi 3, you’ll need to flash Raspberry Pi OS onto an SD card. Start by downloading the latest version of Raspberry Pi OS from the official website. Next, use a tool like Etcher or Win32 Disk Imager to write the OS image to your SD card. Simply select the downloaded image file, choose your SD card as the target, and click “Flash.” Once the process is complete, safely eject the SD card and insert it into your Raspberry Pi 3. You’re now ready to boot up your Pi and begin the Nextcloud installation!
Configuring the Raspberry Pi
To configure your Raspberry Pi for Nextcloud, start by connecting it to your network. If using Wi-Fi, open the terminal and edit the wpa_supplicant.conf file with your network credentials. Next, enable SSH access to securely control your Pi remotely. Open the raspi-config tool, navigate to Interfacing Options, and select SSH to turn it on.
While there, consider changing your Pi’s default password for added security. You may also want to set a static IP address for your Pi to ensure Nextcloud is always accessible at the same URL. This can be done by editing the dhcpcd.conf file and adding your desired static IP, router IP, and domain name server (DNS) addresses.
Finally, update your Pi to the latest software by running ‘sudo apt update’ and ‘sudo apt full-upgrade’ in the terminal. With these basic configurations complete, your Raspberry Pi is ready for the next steps of installing Nextcloud.
Installing Nextcloud
To install Nextcloud on your Raspberry Pi 3, start by updating your system with sudo apt update && sudo apt upgrade. Next, install the necessary dependencies:
sudo apt install apache2 mariadb-server libapache2-mod-php7.3 php7.3-gd php7.3-json php7.3-mysql php7.3-curl php7.3-mbstring php7.3-intl php-imagick php7.3-xml php7.3-zip
Download the latest Nextcloud release with:
wget https://download.nextcloud.com/server/releases/nextcloud-21.0.1.zip
Unzip the package and move it to your web server directory:
unzip nextcloud-21.0.1.zip
sudo mv nextcloud /var/www/html/
Change ownership of the Nextcloud directory to www-data:
sudo chown -R www-data:www-data /var/www/html/nextcloud/
Create a new MySQL database and user for Nextcloud:
sudo mysql -u root -p
CREATE DATABASE nextcloud;
GRANT ALL ON nextcloud.* to 'nextcloud'@'localhost' IDENTIFIED BY 'your_password';
FLUSH PRIVILEGES;
EXIT;
Finally, configure Apache by editing the default virtual host file:
sudo nano /etc/apache2/sites-available/000-default.conf
Add the following lines inside the
DocumentRoot /var/www/html/nextcloud/
Options +FollowSymlinks
AllowOverride All
Require all granted
Save the file, enable Apache modules, and restart the service:
sudo a2enmod rewrite
sudo a2enmod headers
sudo a2enmod env
sudo a2enmod dir
sudo a2enmod mime
sudo systemctl restart apache2
Now you can access the Nextcloud setup wizard by visiting http://your_raspberry_pi_ip/ in a web browser.
Configuring Nextcloud
Once Nextcloud is installed on your Raspberry Pi 3, open a web browser and navigate to your Pi’s IP address to access the initial setup wizard. You’ll be prompted to create an admin account by entering a username and secure password. Next, you can configure your data directory, where Nextcloud will store your files. It’s recommended to use an external storage device for better performance and scalability.
After setting up your admin account and data directory, you’ll be taken to the Nextcloud web interface. Here, you can customize your settings, such as enabling encryption for added security, configuring email notifications, and connecting to external storage providers like Dropbox or Google Drive. Nextcloud also offers a wide range of apps to extend its functionality, which can be installed and managed through the built-in app store.
With the initial configuration complete, you’re ready to start using Nextcloud on your Raspberry Pi 3 to store, sync, and share your files and media.
Securing Your Nextcloud Instance
Enabling HTTPS
To enable HTTPS for secure connections to your Nextcloud instance, you’ll need to configure SSL/TLS certificates. The easiest way is using Let’s Encrypt, a free certificate authority. Install the Certbot client on your Pi with sudo apt install certbot. Then run sudo certbot --apache to automatically obtain and configure a certificate for your domain. Certbot will prompt you for an email address and to agree to the terms of service. Once complete, your Nextcloud site will be accessible over HTTPS, ensuring encrypted transmission of your sensitive data. Remember to set up auto-renewal of your Let’s Encrypt certificate to keep your site secure long-term.
Securing the Raspberry Pi
Securing your Raspberry Pi should be a top priority when setting up Nextcloud. Start by changing the default password for the ‘pi’ user account to a strong, unique password. Enable the built-in firewall and configure it to only allow necessary ports. Regularly update your Raspberry Pi’s operating system and installed packages to patch any vulnerabilities. Consider implementing two-factor authentication for an extra layer of protection. By following security best practices, you can ensure your Nextcloud instance remains private and secure. Remember, a little effort goes a long way in safeguarding your personal data from unauthorized access.
Accessing Your Nextcloud From Anywhere
To access your Nextcloud from anywhere, you’ll need to configure your router to forward the appropriate ports and set up dynamic DNS. Forward ports 80 and 443 to your Raspberry Pi’s local IP address. For enhanced security, consider using a VPN or enabling two-factor authentication in Nextcloud. Next, sign up for a free dynamic DNS service like No-IP or Duck DNS to assign a domain name to your home IP address. Configure your router or a script on the Pi to update this domain whenever your IP changes. Finally, enter your new domain in Nextcloud’s trusted domains setting and you’re ready to access your private cloud securely from anywhere!
