• Custom API Development: Use n8n to create webhooks and simple APIs for external services to trigger workflows.

How to Install n8n: A Step-by-Step Self-Hosted Setup Guide

While n8n offers a cloud-based solution for quick deployment, many users prefer self-hosting to maintain control over their data and infrastructure. Installing n8n manually can be complex, involving Docker, Nginx, and SSL configuration. Fortunately, an automated script like n8n-autoinstall simplifies the process, making it accessible even to those with minimal server management experience. Below is a detailed guide to installing n8n on a Linux server using this script.

Why Use the n8n-autoinstall Script?

The n8n-autoinstall script (available at https://github.com/shahinst/n8n-autoinstall) automates the setup of a self-hosted n8n instance on Ubuntu or Debian servers. It uses Docker and Docker Compose to run n8n, sets up Nginx as a reverse proxy, and integrates Let’s Encrypt for free SSL certificates, ensuring a secure and efficient installation.

Prerequisites for Installation

Before starting, ensure you have the following:

• A Linux server (VPS or dedicated, preferably Ubuntu 20.04 or higher).
• Root or sudo access to execute installation commands.
• A domain or subdomain (e.g., n8n.yourdomain.com) pointed to your server’s IP address.
• SSH access to your server.
• git installed on the server (sudo apt update && sudo apt install git -y).

Step-by-Step Installation Process

Follow these steps to install n8n using the automated script:

1. Connect to Your Server: Use SSH to access your server.
2. ssh your_username@YOUR_SERVER_IP
3. Download the n8n-autoinstall Script: Clone the repository containing the script.
   1. git clone https://github.com/shahinst/n8n-autoinstall.git
   1. cd n8n-autoinstall
4. Make the Script Executable: Grant execution permissions to the script.
   1. chmod +x install.sh
5. Run the Script: Execute the script with sudo privileges.
   1. sudo ./install.sh
6. Answer the Prompts: The script will prompt you for:
   1. Domain Name: Enter the domain or subdomain for accessing n8n (e.g., n8n.yourdomain.com).
   1. Email Address: Provide an email for SSL certificate registration with Let’s Encrypt (used for renewals).
   1. Basic Auth Credentials (Optional): Set a username and password for an additional security layer.
7. Automated Setup: The script handles everything behind the scenes:
   1. Installs Docker and Docker Compose.
   1. Configures Nginx as a reverse proxy.
   1. Obtains and sets up a free SSL certificate using Let’s Encrypt.
   1. Creates and starts the n8n container with persistent data storage via Docker volumes.
   1. Configures environment variables for optimal performance.
8. Access n8n:

Once the installation completes, open your browser and navigate to the specified domain (e.g., https://n8n.yourdomain.com). If Basic Auth is enabled, enter the credentials. You’ll then be directed to the n8n setup page to create your account and start building workflows.

Technical Insights: How the Script Works

• Docker & Docker Compose: Runs n8n in an isolated container, ensuring dependency management and portability. Docker Compose simplifies configuration, while data persistence is achieved through volumes.
• Nginx Reverse Proxy: Manages incoming traffic, forwarding requests to the n8n container and handling SSL termination for secure HTTPS connections.
• Let’s Encrypt SSL: Automates the issuance and renewal of SSL certificates using Certbot, ensuring your n8n instance remains secure.

Using the n8n-autoinstall script eliminates the need to manually configure complex components, allowing you to focus on building workflows rather than managing infrastructure.
