Installation: Getting NZBGet Up and Running

The installation process for NZBGet is designed to be straightforward, ensuring that you can begin downloading with minimal delay. We will guide you through the recommended installation methods, emphasizing best practices for a smooth and efficient setup.

Official Package Installation

For most Linux distributions, the most accessible and recommended method is to install NZBGet via your distribution’s official package manager. This approach ensures that you are installing a stable and well-tested version of the software, with dependencies handled automatically.

For systems utilizing pacman, such as Arch Linux and its derivatives, the primary package is simply nzbget. This will install the core NZBGet application.

sudo pacman -S nzbget

In conjunction with the main package, we highly recommend installing the optional nzbget-systemd package. This package provides a pre-configured systemd service file. A systemd service allows NZBGet to run in the background as a system service, ensuring it starts automatically on boot and can be managed easily using standard systemd commands.

sudo pacman -S nzbget-systemd

This combination of installing the nzbget package and the nzbget-systemd service file provides a robust and automated setup for NZBGet. It eliminates the need for manual startup scripts and ensures NZBGet is always running when you need it.

Development Version from AUR

For users who prefer to stay on the bleeding edge or require the absolute latest features and bug fixes, the Arch User Repository (AUR) offers a development version. This is packaged as nzbget-git. Installing from the AUR requires an AUR helper like yay or paru.

Using yay:

yay -S nzbget-git

Using paru:

paru -S nzbget-git

The nzbget-git package also typically includes the necessary systemd service file, providing the same benefits of automated background operation as the official nzbget-systemd package.

Running NZBGet Under a Different User

A crucial aspect of securing your NZBGet installation is running it under a dedicated, unprivileged user. Running applications as root is generally discouraged due to security risks. By creating a specific user for NZBGet, you limit the potential impact of any security vulnerabilities.

While the official NZBGet package and its systemd service might default to running as root or a generic user, it is best practice to configure it to run under a dedicated user. This often involves creating a user specifically for NZBGet (e.g., nzbget), ensuring appropriate file permissions for its configuration and download directories, and then modifying the systemd service file to specify this user.

The exact steps can vary slightly depending on your distribution and how the service file is structured, but the general principle involves editing the nzbget.service file (often located in /etc/systemd/system/ or /usr/lib/systemd/system/) and adding or modifying User= and Group= directives within the [Service] section. You would then ensure this user has read and write access to the necessary directories where NZBGet stores its configuration and downloads.

This practice is fundamental for maintaining a secure and well-managed NZBGet instance. We strongly advocate for this approach to enhance the overall security posture of your system.

Configuration: Tailoring NZBGet to Your Needs

Once NZBGet is installed, the next critical step is its configuration. The web-based interface makes this process intuitive, allowing you to customize various aspects of its operation to perfectly match your requirements.

Accessing the Web Interface

By default, NZBGet runs on port 6789. You can access its web interface by navigating to http://your-server-ip:6789 or http://localhost:6789 (if you are accessing it from the same machine).

Upon your first access, you will likely be prompted to set a username and password for security. It is imperative to choose strong credentials to protect your NZBGet instance from unauthorized access.

Essential Configuration Settings

Within the web interface, you will find numerous settings to fine-tune NZBGet. We will highlight some of the most important ones:

  • Download Directory: This is where NZBGet will save your downloaded files. Ensure this directory exists and that the user NZBGet runs as has write permissions. It’s good practice to dedicate a specific partition or drive for downloads to manage space effectively.
  • Completed Download Directory: After a download is successfully completed and verified, NZBGet can move it to a separate directory. This is useful for organizing your files and for integration with other media management software.
  • Server Settings: This section is crucial for connecting to your Usenet provider(s). You will need to enter the hostname, port, username, and password provided by your Usenet provider. If you use multiple providers, NZBGet supports configuring them as backups or for load balancing.
  • Download Settings: Here, you can configure options such as the maximum number of simultaneous downloads, download speed limits (if desired), and how NZBGet handles incomplete downloads.
  • Post-processing Settings: NZBGet has powerful post-processing capabilities. You can configure it to automatically unpack downloaded archives, repair corrupted files using PAR2, and even integrate with external tools like Sonarr, Radarr, or Plex Media Server.
  • Login/Password Settings: As mentioned earlier, securing your web interface with a strong username and password is vital. You can also configure HTTPS for encrypted access.

We encourage users to explore all available settings. Even seemingly minor adjustments can significantly improve performance and streamline your download workflow. The detailed tooltips and explanations within the NZBGet interface itself are also invaluable resources.

Starting and Managing NZBGet

Once configured, starting and managing NZBGet is straightforward, especially when utilizing the systemd service.

Manual Startup (Console Mode)

If you are running NZBGet manually, you can start it in console mode. This is useful for initial testing or if the systemd service is not available or configured.

To start NZBGet in console mode, you will typically use the nzbget command with the -c flag to specify your configuration file. The default configuration file path is often /var/lib/nzbget/.nzbget/nzbget.conf.

nzbget -c /var/lib/nzbget/.nzbget/nzbget.conf -s

The -s flag indicates that NZBGet should run in single user mode (console mode).

Manual Startup (Daemon Mode)

For background operation without systemd, you can start NZBGet in daemon mode using the -D flag.

nzbget -c /var/lib/nzbget/.nzbget/nzbget.conf -D

The -D flag signifies daemon mode, allowing NZBGet to run independently of your current terminal session.

Managing with systemd

When you have installed the nzbget-systemd package or a similar systemd service file, managing NZBGet becomes significantly easier. The systemctl command is your primary tool.

  • Starting the service:

    sudo systemctl start nzbget.service

  • Stopping the service:

    sudo systemctl stop nzbget.service

  • Restarting the service (after configuration changes):

    sudo systemctl restart nzbget.service

  • Checking the service status:

    sudo systemctl status nzbget.service

    This command will show you if NZBGet is running, any recent log entries, and whether it encountered any errors.

  • Enabling the service to start on boot:

    sudo systemctl enable nzbget.service

  • Disabling the service from starting on boot:

    sudo systemctl disable nzbget.service

Using systemd is the most robust and recommended method for managing NZBGet, as it integrates seamlessly with your operating system’s service management.
