In today’s world, the desire for private cloud storage has grown exponentially. Organizations and individuals alike seek to maintain control over their data, ensuring both security and accessibility. One cost-effective solution to achieve this is by configuring a secure file server using a Raspberry Pi 4 and Nextcloud. This article will guide you through the entire process, from installation to configuration, ensuring you have a robust and secure Nextcloud server running on your Raspberry Pi 4.
To begin, let's prepare your Raspberry Pi 4 for the installation of Nextcloud. The Raspberry Pi needs to be running an up-to-date version of Raspberry Pi OS.

With your Raspberry Pi ready, it’s time to install Nextcloud. Nextcloud is a powerful tool for creating your own cloud storage and managing your data securely.
First, install the necessary packages. Open the terminal and execute the following commands:
sudo apt install apache2 mariadb-server libapache2-mod-php7.3 -y
sudo apt install php7.3 php7.3-gd php7.3-json php7.3-mysql php7.3-curl php7.3-mbstring php7.3-intl php7.3-imagick php7.3-xml php7.3-zip -y
These commands will install Apache, MariaDB, and PHP, which are required for running Nextcloud.
Next, secure and configure your MariaDB installation:
sudo mysql_secure_installation
Follow the prompts to set a root password and remove anonymous users and test databases for security.
Create a new database and user for Nextcloud:
sudo mysql -u root -p
CREATE DATABASE nextcloud;
CREATE USER 'nextclouduser'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextclouduser'@'localhost';
FLUSH PRIVILEGES;
exit;
Replace 'password' with a strong password of your choice.
Download the latest version of Nextcloud:
wget https://download.nextcloud.com/server/releases/latest.tar.bz2
tar -xjf latest.tar.bz2
sudo mv nextcloud /var/www/html/
Change the ownership of the Nextcloud directory to the web server user:
sudo chown -R www-data:www-data /var/www/html/nextcloud/
sudo chmod -R 755 /var/www/html/nextcloud/
Create a Nextcloud configuration file in Apache:
sudo nano /etc/apache2/sites-available/nextcloud.conf
Add the following content:
<VirtualHost *:80>
DocumentRoot /var/www/html/nextcloud/
<Directory /var/www/html/nextcloud/>
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
Enable the Nextcloud site and the required Apache modules:
sudo a2ensite nextcloud.conf
sudo a2enmod rewrite headers env dir mime
sudo systemctl restart apache2
For storing large amounts of data, an external hard drive or external storage device is ideal.
Format the external storage device to a compatible file system (ext4 is recommended). Mount the external drive:
sudo mkdir /mnt/nextcloud
sudo mount /dev/sda1 /mnt/nextcloud
To ensure the drive mounts automatically at boot, edit the fstab:
sudo nano /etc/fstab
Add the following line:
/dev/sda1 /mnt/nextcloud ext4 defaults 0 2
Now, set the Nextcloud data directory to use the mounted external storage:
sudo mkdir /mnt/nextcloud/data
sudo chown -R www-data:www-data /mnt/nextcloud/data
Edit the Nextcloud configuration file to point to the new data directory. Open config.php:
sudo nano /var/www/html/nextcloud/config/config.php
Modify the 'datadirectory' entry to:
'datadirectory' => '/mnt/nextcloud/data',
Security is paramount for any cloud server. Implement these steps to enhance your server’s security:
Install Certbot for Apache:
sudo apt install certbot python3-certbot-apache -y
Obtain and install an SSL certificate:
sudo certbot --apache
Follow the prompts to complete the SSL setup. This will allow secure access to your Nextcloud server via HTTPS.
Nextcloud offers several built-in security features. Navigate to your Nextcloud web interface and log in with your admin credentials. Go to Settings > Security and enable options such as:
Regularly updating your server and Nextcloud instance is crucial. Perform updates with:
sudo apt update && sudo apt upgrade -y
For Nextcloud updates, use the built-in updater found in the admin settings.
With everything set up, you can now access your private cloud server through any web browser. Just enter your server’s IP address or domain name. The web interface allows you to upload, organize, and share files seamlessly.
Nextcloud’s mobile and desktop clients offer additional convenience, allowing you to sync files across devices effortlessly. Install the Nextcloud app on your smartphone and desktop to get started.
In conclusion, setting up a secure file server using a Raspberry Pi 4 and Nextcloud is both feasible and highly rewarding. By following the steps outlined in this guide, you can create a robust cloud storage solution tailored to your needs. This setup not only provides security and privacy but also offers flexibility and control over your data. Embrace the power of the Raspberry Pi and Nextcloud to take command of your digital storage today.
