How to Install and Configure Nextcloud on Ubuntu 24

Nextcloud is a self-hosted, open-source cloud storage and collaboration platform that gives you complete control over your data. Setting it up on Ubuntu 24 provides a robust foundation for file sharing, calendar synchronization, document collaboration, and contact management without relying on third-party services like Google Drive or Dropbox. This guide walks you through the entire installation and configuration process, covering everything from Apache setup to SSL certificates, plus troubleshooting common issues you’ll likely encounter.

Prerequisites and System Requirements

Before diving into the installation, make sure your Ubuntu 24 system meets the minimum requirements. You’ll need at least 2GB of RAM (4GB recommended), 20GB of disk space, and a fresh Ubuntu 24 server installation with root access.

Ubuntu 24.04 LTS server
Minimum 2GB RAM (4GB+ recommended for production)
At least 20GB available disk space
Root or sudo access
Domain name pointing to your server (optional but recommended)

If you’re running this on a VPS, services like MangoHost VPS provide excellent performance for Nextcloud installations with their SSD storage and reliable network connectivity.

Installing the LAMP Stack

Nextcloud runs on a LAMP stack (Linux, Apache, MySQL/MariaDB, PHP), so we’ll start by installing these components. Ubuntu 24 comes with updated versions that work perfectly with the latest Nextcloud release.

sudo apt update && sudo apt upgrade -y
sudo apt install apache2 mariadb-server php php-cli php-fpm php-json php-intl php-imagick php-pdo php-mysql php-zip php-gd php-mbstring php-curl php-xml php-pear php-bcmath -y

Start and enable the necessary services:

sudo systemctl start apache2
sudo systemctl enable apache2
sudo systemctl start mariadb
sudo systemctl enable mariadb

Verify your PHP installation and check the version:

php -v

Ubuntu 24 typically ships with PHP 8.3, which is fully compatible with Nextcloud 28+. You should see output showing PHP 8.3.x with the Zend Engine.

Database Configuration

Secure your MariaDB installation and create a database for Nextcloud. The mysql_secure_installation script helps lock down the default MariaDB configuration:

sudo mysql_secure_installation

Follow the prompts to set a root password, remove anonymous users, and disable remote root login. Next, create the Nextcloud database and user:

sudo mysql -u root -p

CREATE DATABASE nextcloud;
CREATE USER 'nextclouduser'@'localhost' IDENTIFIED BY 'your_strong_password_here';
GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextclouduser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Replace ‘your_strong_password_here’ with a genuinely strong password. Consider using a password manager to generate and store it securely.

Downloading and Installing Nextcloud

Download the latest Nextcloud release directly from the official repository. Always grab the latest stable version for security updates and new features:

cd /tmp
wget https://download.nextcloud.com/server/releases/latest.tar.bz2
tar -xjf latest.tar.bz2
sudo cp -r nextcloud /var/www/html/

Set the correct permissions for the web server. This is crucial for Nextcloud to function properly:

sudo chown -R www-data:www-data /var/www/html/nextcloud/
sudo chmod -R 755 /var/www/html/nextcloud/

Apache Virtual Host Configuration

Create a dedicated Apache virtual host for Nextcloud. This approach is cleaner than using the default site and allows for better configuration management:

sudo nano /etc/apache2/sites-available/nextcloud.conf

Add the following configuration:

<VirtualHost *:80>
    ServerName your-domain.com
    DocumentRoot /var/www/html/nextcloud/
    
    <Directory /var/www/html/nextcloud/>
        Require all granted
        AllowOverride All
        Options FollowSymLinks MultiViews
        
        <IfModule mod_dav.c>
            Dav off
        </IfModule>
    </Directory>
    
    ErrorLog ${APACHE_LOG_DIR}/nextcloud_error.log
    CustomLog ${APACHE_LOG_DIR}/nextcloud_access.log combined
</VirtualHost>

Enable the site and required Apache modules:

sudo a2ensite nextcloud.conf
sudo a2enmod rewrite headers env dir mime
sudo systemctl restart apache2

PHP Configuration Optimization

Nextcloud requires specific PHP settings for optimal performance. Edit the PHP configuration file:

sudo nano /etc/php/8.3/apache2/php.ini

Modify these key settings:

memory_limit = 512M
upload_max_filesize = 500M
post_max_size = 500M
max_execution_time = 300
max_input_time = 300
date.timezone = America/New_York

Change the timezone to match your location. You can find valid timezone strings in the PHP documentation.

Restart Apache to apply the changes:

sudo systemctl restart apache2

Web-Based Installation

Navigate to your server’s IP address or domain name in a web browser. You’ll see the Nextcloud setup wizard. Fill in the following information:

Admin username and password (choose something secure)
Data folder path (default is fine for most installations)
Database type: MySQL/MariaDB
Database name: nextcloud
Database username: nextclouduser
Database password: the password you created earlier
Database host: localhost

The installation process takes a few minutes. Don’t close the browser window during this time.

SSL Certificate Configuration

Running Nextcloud without HTTPS is a security risk. Install Let’s Encrypt for free SSL certificates:

sudo apt install certbot python3-certbot-apache -y
sudo certbot --apache -d your-domain.com

Certbot automatically configures Apache with the SSL certificate and sets up auto-renewal. Test the renewal process:

sudo certbot renew --dry-run

Performance Optimization and Caching

Nextcloud performance improves significantly with proper caching. Install Redis for memory caching:

sudo apt install redis-server php-redis -y
sudo systemctl start redis-server
sudo systemctl enable redis-server

Add Redis configuration to Nextcloud’s config file:

sudo nano /var/www/html/nextcloud/config/config.php

Add these lines before the closing array bracket:

'memcache.local' => '\OC\Memcache\Redis',
'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
'redis' => array(
    'host' => 'localhost',
    'port' => 6379,
),

Common Issues and Troubleshooting

Here are the most frequent problems you’ll encounter and their solutions:

Issue	Symptom	Solution
File upload fails	Large files don’t upload	Increase PHP upload limits and restart Apache
Permission errors	Can’t write to directories	Fix ownership: chown -R www-data:www-data /var/www/html/nextcloud/
Database connection error	Can’t connect to database	Verify credentials in config.php and database accessibility
Memory limit exceeded	White screen or 500 errors	Increase memory_limit in php.ini

If you encounter the “trusted domains” error, add your domain to the config file:

'trusted_domains' => 
array (
  0 => 'localhost',
  1 => 'your-domain.com',
  2 => 'your-server-ip',
),

Security Hardening

Implement additional security measures for production environments:

sudo ufw enable
sudo ufw allow ssh
sudo ufw allow 80
sudo ufw allow 443

Configure fail2ban to prevent brute force attacks:

sudo apt install fail2ban -y
sudo nano /etc/fail2ban/jail.local

Add Nextcloud-specific protection:

[nextcloud]
enabled = true
port = 80,443
protocol = tcp
filter = nextcloud
maxretry = 3
bantime = 1800
logpath = /var/log/apache2/nextcloud_access.log

You can connect it to LDAP/Active Directory for user authentication, set up external storage to mount existing file systems, and use the API for custom integrations. The talk app provides video conferencing capabilities, making it a comprehensive collaboration platform.

For high-traffic installations, consider using dedicated servers with multiple CPU cores and substantial RAM. Nextcloud scales well vertically, and the performance improvements are noticeable with better hardware.

Maintenance and Updates

Keep your Nextcloud installation updated through the web interface or command line. The updater app provides a user-friendly update process, but you can also use the occ command-line tool:

sudo -u www-data php /var/www/html/nextcloud/occ upgrade

Regular database maintenance improves performance:

sudo -u www-data php /var/www/html/nextcloud/occ db:add-missing-indices
sudo -u www-data php /var/www/html/nextcloud/occ db:convert-filecache-bigint

Set up automated backups of both files and database. A simple backup script might look like:

#!/bin/bash
DATE=$(date +%Y%m%d_%H%M%S)
mysqldump -u root -p nextcloud > /backup/nextcloud_db_$DATE.sql
tar -czf /backup/nextcloud_files_$DATE.tar.gz /var/www/html/nextcloud/

Your Nextcloud installation should now be fully functional with proper security, performance optimization, and monitoring in place. Regular maintenance and staying current with updates will ensure a stable, secure cloud storage solution that gives you complete control over your data.
