System Requirements and Prerequisites

Hardware Requirements

n8n’s hardware requirements vary significantly based on workflow complexity and concurrent execution demands. For development and testing environments, minimum specifications include 2GB RAM, 2 CPU cores, and 20GB storage. However, production deployments benefit substantially from enhanced specifications.

Recommended production hardware includes 4-8GB RAM to handle multiple concurrent workflows, 4 CPU cores for parallel execution capabilities, and 40GB SSD storage for optimal database performance. Large-scale deployments processing hundreds of workflows daily may require 16GB RAM or more, depending on data processing requirements.

Network connectivity plays a crucial role in n8n performance since workflows frequently interact with external APIs and services. Stable internet connectivity with adequate bandwidth ensures reliable webhook processing and external service integration. Consider your organization’s peak usage patterns when sizing hardware resources.

Software Prerequisites

Successful n8n installation requires a freshly updated Debian 13 system with sudo privileges for package installation and service configuration. Basic command-line knowledge is essential for following installation procedures and troubleshooting potential issues.

Domain name registration is recommended for production deployments, particularly when implementing SSL certificates and reverse proxy configurations. While not strictly required for local development, a proper domain simplifies webhook configuration and external service integration.

Ensure the system has sufficient entropy for SSL certificate generation and secure session management. Debian 13 includes improved entropy generation, but verify adequate randomness availability before beginning installation procedures.

Installation Method Comparison

Docker Installation (Recommended)

Docker installation offers the most straightforward path to production-ready n8n deployment with several compelling advantages. Container isolation protects the host system from potential conflicts while ensuring consistent environments across development and production systems.

Easy updates represent another significant benefit, as new n8n versions deploy through simple container replacement without complex dependency management. Docker’s consistent environment eliminates the “works on my machine” problem that often plagues traditional installations.

However, Docker introduces resource overhead and requires familiarity with container concepts. Despite these considerations, Docker installation remains the recommended approach for most users, particularly those new to n8n or deploying in production environments.

npm/Node.js Installation

Direct npm installation provides lower resource usage and direct system access, making it attractive for development environments or resource-constrained systems. This approach eliminates container overhead and provides direct access to system resources and file systems.

The main disadvantages include complex dependency management, manual update procedures, and potential conflicts with other Node.js applications. System dependency management becomes your responsibility, requiring ongoing maintenance and troubleshooting expertise.

This installation method suits advanced users comfortable with Node.js ecosystem management and development environments where direct system access is necessary. Production deployments should carefully consider the maintenance overhead before choosing this approach.

Docker Compose Installation

Docker Compose provides sophisticated multi-container orchestration capabilities ideal for complex production deployments. This approach excels when integrating external databases, reverse proxies, and monitoring solutions within a unified deployment stack.

The additional complexity requires understanding of Docker Compose syntax and multi-container networking concepts. However, this complexity delivers powerful benefits for production environments requiring database separation, load balancing, or horizontal scaling capabilities.

Production deployments with external PostgreSQL databases, Nginx reverse proxies, or monitoring solutions benefit significantly from Docker Compose orchestration. The approach provides production-grade deployment patterns while maintaining the benefits of containerization.

Method 1: Docker Installation

Installing Docker on Debian 13

Begin by updating the Debian system to ensure access to the latest package repositories and security patches:

sudo apt update && sudo apt upgrade -y
sudo apt install -y apt-transport-https ca-certificates curl gnupg lsb-release

Add the official Docker repository to access the latest Docker Engine releases:

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker Engine and Docker Compose:

sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

Configure user permissions to manage Docker containers without sudo access:

sudo usermod -aG docker $USER
newgrp docker

Verify the installation by checking Docker version and running a test container:

docker --version
docker run hello-world

Running n8n with Docker

Launch n8n using the official Docker image with persistent data storage:

docker run -it --rm \
  --name n8n \
  -p 5678:5678 \
  -v n8n_data:/home/node/.n8n \
  n8n/n8n

This command creates a named volume for data persistence, maps port 5678 for web interface access, and starts n8n in interactive mode. The container automatically downloads the latest n8n image and initializes the application.

For production deployments, run n8n as a daemon with automatic restart capabilities:

docker run -d \
  --name n8n \
  --restart unless-stopped \
  -p 5678:5678 \
  -v n8n_data:/home/node/.n8n \
  -e WEBHOOK_URL=https://yourdomain.com \
  n8n/n8n

Monitor container status and logs using Docker management commands:

docker ps
docker logs n8n
docker stop n8n
docker start n8n

Docker Compose Setup

Create a dedicated project directory for organized n8n deployment management:

mkdir ~/n8n-docker && cd ~/n8n-docker

Create a comprehensive docker-compose.yml file for production deployment:

version: '3.8'
services:
  n8n:
    image: n8n/n8n
    container_name: n8n
    restart: unless-stopped
    ports:
      - "5678:5678"
    environment:
      - WEBHOOK_URL=https://yourdomain.com
      - GENERIC_TIMEZONE=UTC
      - N8N_SECURE_COOKIE=false
    volumes:

node --version
npm --version

Create a dedicated system user for n8n to enhance security isolation:

sudo useradd --system --shell /bin/bash --home /opt/n8n --create-home n8n
sudo usermod -aG sudo n8n

Configure the n8n user environment for proper application execution:

sudo -u n8n bash
cd /opt/n8n
npm config set prefix ~/.local
echo 'export PATH=$HOME/.local/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

Installing n8n via npm

Install n8n globally for system-wide availability:

sudo -u n8n npm install -g n8n

Alternative local installation within a project directory:

mkdir ~/n8n-project && cd ~/n8n-project
npm init -y
npm install n8n

Verify successful installation by checking the n8n version:

n8n --version

Create initial configuration to customize n8n behavior:

mkdir -p ~/.n8n
echo 'N8N_BASIC_AUTH_ACTIVE=true' > ~/.n8n/.env
echo 'N8N_BASIC_AUTH_USER=admin' >> ~/.n8n/.env
echo 'N8N_BASIC_AUTH_PASSWORD=secure_password' >> ~/.n8n/.env

Configuration and Service Setup

sudo npm install -g pm2
pm2 start n8n --name "n8n-workflow"
pm2 startup
pm2 save

Database Configuration

Database Options Overview

n8n supports multiple database backends with varying performance and scalability characteristics. SQLite serves as the default database for development environments, providing zero-configuration startup with file-based storage suitable for single-user scenarios and workflow prototyping.

PostgreSQL represents the recommended production database choice, offering superior performance, concurrent access capabilities, and advanced features like JSON indexing and full-text search. MySQL provides an alternative relational database option with broad compatibility and established operational practices.

Production deployments benefit significantly from external database separation, enabling horizontal scaling, backup strategies, and performance optimization independent of the n8n application layer. Consider your organization’s database expertise and operational requirements when selecting the appropriate backend.

PostgreSQL Setup

Install PostgreSQL 15 on Debian 13 for optimal n8n compatibility:

sudo apt install -y postgresql postgresql-contrib
sudo systemctl start postgresql
sudo systemctl enable postgresql

Create a dedicated database and user for n8n:

sudo -u postgres psql
CREATE DATABASE n8n;
CREATE USER n8n_user WITH PASSWORD 'secure_database_password';
GRANT ALL PRIVILEGES ON DATABASE n8n TO n8n_user;
ALTER USER n8n_user CREATEDB;
\q

Configure PostgreSQL for optimal n8n performance:

sudo nano /etc/postgresql/15/main/postgresql.conf

Adjust these key parameters:

max_connections = 100
shared_buffers = 256MB
effective_cache_size = 1GB
work_mem = 4MB

Test database connectivity before proceeding with n8n configuration:

psql -h localhost -U n8n_user -d n8n -c "SELECT version();"

n8n Database Configuration

Configure n8n to use PostgreSQL by setting appropriate environment variables:

export DB_TYPE=postgresdb
export DB_POSTGRESDB_HOST=localhost
export DB_POSTGRESDB_PORT=5432
export DB_POSTGRESDB_DATABASE=n8n
export DB_POSTGRESDB_USER=n8n_user
export DB_POSTGRESDB_PASSWORD=secure_database_password

For Docker deployments, add database configuration to the docker-compose.yml environment section:

environment:
  - DB_TYPE=postgresdb
  - DB_POSTGRESDB_HOST=postgres
  - DB_POSTGRESDB_PORT=5432
  - DB_POSTGRESDB_DATABASE=n8n
  - DB_POSTGRESDB_USER=n8n
  - DB_POSTGRESDB_PASSWORD=n8n_password

Initialize the database schema by starting n8n, which automatically creates required tables:

n8n start

Monitor the startup logs to confirm successful database connection and schema initialization. Address any connection errors before proceeding with additional configuration steps.

Security Configuration

Firewall Setup

Implement UFW (Uncomplicated Firewall) to control network access to your n8n installation:

sudo apt install -y ufw
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow ssh
sudo ufw allow 5678/tcp
sudo ufw --force enable

For production deployments with reverse proxy, allow HTTP and HTTPS traffic:

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw delete allow 5678/tcp

Install and configure Fail2ban for brute-force protection:

sudo apt install -y fail2ban
sudo systemctl enable fail2ban
sudo systemctl start fail2ban

Create a custom Fail2ban configuration for n8n:

sudo tee /etc/fail2ban/jail.d/n8n.conf > /dev/null <

User Authentication

Configure initial admin user during first n8n startup by accessing the web interface at http://your-server-ip:5678. Create a strong password combining uppercase, lowercase, numbers, and special characters with minimum 12-character length.

Enable basic authentication for additional security layers:

export N8N_BASIC_AUTH_ACTIVE=true
export N8N_BASIC_AUTH_USER=admin
export N8N_BASIC_AUTH_PASSWORD=complex_password

Implement user management best practices including regular password rotation, account deactivation for departed team members, and principle of least privilege for workflow access permissions. Consider implementing multi-factor authentication through reverse proxy solutions for enhanced security.

Reverse Proxy Setup

Install and configure Nginx for SSL termination and security header implementation:

sudo apt install -y nginx
sudo systemctl enable nginx
sudo systemctl start nginx

Create an Nginx virtual host configuration for n8n:

sudo tee /etc/nginx/sites-available/n8n > /dev/null <

Enable the site and test configuration:

sudo ln -s /etc/nginx/sites-available/n8n /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx

Configure WebSocket support for real-time workflow monitoring:

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;

SSL/TLS Setup

Let’s Encrypt Configuration

Install Certbot for automated SSL certificate management:

sudo apt install -y certbot python3-certbot-nginx

Generate SSL certificates for your domain:

sudo certbot --nginx -d yourdomain.com

Verify automatic renewal functionality:

sudo certbot renew --dry-run

Configure Nginx with enhanced SSL settings:

server {
    listen 443 ssl http2;
    server_name yourdomain.com;
    
    ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;
    
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512;
    ssl_prefer_server_ciphers off;
    
    add_header Strict-Transport-Security "max-age=63072000" always;
    
    location / {
        proxy_pass http://localhost:5678;
        # ... additional proxy configuration
    }
}

Set up automatic certificate renewal through systemd timer:

sudo systemctl status certbot.timer
sudo systemctl enable certbot.timer

Alternative SSL Methods

For development environments, create self-signed certificates:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
    -keyout /etc/ssl/private/n8n-selfsigned.key \
    -out /etc/ssl/certs/n8n-selfsigned.crt

Commercial SSL certificates require certificate authority validation and manual installation procedures. Purchase certificates from trusted providers and follow their installation instructions for Nginx integration.

Test SSL configuration using online tools like SSL Labs SSL Test to verify proper implementation and security grade achievement.
