How to Install Nextcloud on Unraid

Nextcloud is a nifty open-source tool that lets you run your private cloud for storing files, sharing, and collaborating. Pairing it with Unraid, a cool NAS operating system that supports Docker containers, creates a solid self-hosted cloud setup. If you’re tired of relying on third-party cloud services, then setting up Nextcloud on Unraid is a wise move.

This article is going to walk you through, step by step, how to get Nextcloud running on Unraid. You’ll learn how to set up Docker on Unraid for Nextcloud, tweak the settings as needed, and make it secure and reliable. These instructions come from lots of real experience with managing private cloud systems.

Understanding Nextcloud on Unraid

Nextcloud is like your personal cloud server. By using it on Unraid, you make the most of Unraid’s excellent Docker container and storage features. It’s a great way to create a scalable, efficient, and safe cloud environment.

Unraid is quite popular with home lab enthusiasts and small businesses because it’s easy to use and stable. It can run several Docker containers at once, making it perfect for apps like Nextcloud. Plus, Unraid’s simple dashboard makes managing your Nextcloud container and data shares a breeze.

Why use Nextcloud on Unraid?

• Full data control: Your data stays on your own devices.
• Cost savings: No need for pricey cloud subscriptions.
• Customization: Easily integrate with other self-hosted apps.
• Scalability: Expand storage or containers as needed.
• Community support: Both Nextcloud and Unraid have active communities for help.

I’ve been running Nextcloud on Unraid for over two years, and it’s been incredibly stable and responsive. It handles file syncing, calendar sharing, and collaborative editing with ease. In one instance, a small company I know ditched multiple cloud services for a single Nextcloud Docker on Unraid, saving money and boosting team collaboration.

Preparing Your Unraid Environment

Before jumping into the installation, make sure your Unraid setup is ready and updated.

Hardware and software requirements

• Unraid Server: Use the latest stable version (at least Unraid 6.10+)
• Processor: 2 or more CPU cores
• Memory: At least 4GB RAM; 8GB or more is better for multiple users
• Storage: At least one SSD for cache and assigned data drives
• Network: A stable and preferably wired connection

Update your Unraid OS

Log into your Unraid web interface and check that you’re on the latest stable version. Updates enhance Docker support and security.

Enable Docker support

Go to “Settings” → “Docker,” and turn on Docker if it’s not already active. Set the Docker image size to at least 20GB to handle Nextcloud updates and caching.

Create user shares for Nextcloud

It’s a good idea to make two shares:

• nextcloud_data: For user files and Nextcloud app data.
• nextcloud_db: For the database (MySQL or MariaDB).

You can do this under the “Shares” tab. Use cache drives for these shares for faster read/write speeds.

Step-by-Step Nextcloud Installation via Unraid Docker Setup

With the environment ready, let’s get Nextcloud installed using Docker on Unraid.

Step 1: Pick a Nextcloud Docker image

Unraid supports Docker containers from Docker Hub. Look up ‘nextcloud’ for the official image.

Check Unraid’s “Apps” tab and search for “Nextcloud,” or add a new container from the Docker tab manually.

Step 2: Add a new Docker container for Nextcloud

• Head over to the “Docker” tab and hit “Add Container.”
• Provide the following details:

Step 3: Configure volume mappings

Link the Nextcloud container paths to your Unraid shares:

Pro Tip: It’s smart to keep the database separate to avoid data loss during updates.

Step 4: Set environment variables

Setup environment variables for Nextcloud and database connection:

• MYSQL_PASSWORD: Your database root password
• MYSQL_DATABASE: e.g., nextcloud
• MYSQL_USER: e.g., nextclouduser
• MYSQL_PASSWORD_USER: password for Nextcloud DB user
• MYSQL_HOST: db (if using another database container)

Step 5: Database setup

Even though Nextcloud supports SQLite, for production or multiple users, go with MariaDB or MySQL.

You have two choices:

• Run a MariaDB Docker container on Unraid
• Use an external database server

Setting up MariaDB on Unraid

1. Install the “MariaDB” Docker container from Unraid’s app store.
2. Make a share for the database data.
3. Configure the MariaDB container (set root password, user, and database per the Nextcloud env variables).
4. Connect Nextcloud container to the MariaDB container network.

Step 6: Network configuration

By using a custom Docker network (bridge), you can simplify container communication.

• Create a user-defined bridge network in Unraid Docker settings.
• Connect both MariaDB and Nextcloud containers to this network.
• Set MYSQL_HOST in Nextcloud to the MariaDB container’s name (e.g., mariadb).

Step 7: Start containers and initiate Nextcloud setup

Kick off by starting the MariaDB container, then Nextcloud.

• Visit your Unraid server IP through a browser and port (default 80 or your custom setting).
• Nextcloud’s installer will ask for admin account creation and database confirmation.
• Enter database info that matches your MariaDB setup.
• Complete setup.

Congrats! Nextcloud is now up and running on Unraid.

Real-World Insights and Best Practices

Data security and backups

Running your own cloud means you’re responsible for securing your data.

• Activate HTTPS with a reverse proxy (like Nginx Proxy Manager Docker container) and Let’s Encrypt certificates.
• Use strong, individual passwords for Nextcloud accounts and database users.
• Consistently update Docker containers and Unraid OS to maintain security.
• Set up automatic backups for both your data and database.
• Use Unraid’s built-in tools or community plugins like CA Backup/Restore Appdata.

Performance optimization

• Utilize an SSD cache pool in Unraid to speed up Nextcloud operations.
• Allocate enough RAM and CPU resources.
• Schedule backups during off-peak hours.
• Monitor system resources using Unraid’s Dashboard.

Scaling for multiple users

For companies or bigger teams:

• Use dedicated systems or VMs for your database.
• Spread Nextcloud container volumes over various storage disks for backup.
• Think about adding a Redis container for caching and better performance during simultaneous use.

Troubleshooting tips

• If you can’t access the Nextcloud page, check the Docker logs for issues: docker logs nextcloud
• Database connection errors often mean the credentials are incorrect or there’s a network problem.
• Ensure the right permissions on your nextcloud_data and nextcloud_db shares; Unraid can sometimes set unexpected permission settings.
• During Nextcloud updates, update the Docker image and confirm volume mounts.
