How to Install n8n on a Cloud Server

n8n is a powerful open-source automation tool that allows users to create and manage workflows connecting various services. Installing n8n on a cloud server makes it accessible from anywhere and provides scalability. This guide will walk you through the necessary steps to install n8n on a cloud server effectively.

Prerequisites

Before you begin the installation process, consider the following prerequisites:

1. Choose a Cloud Provider: Select a cloud service provider such as AWS, Google Cloud, or DigitalOcean based on your performance needs.
2. Create an Account: Sign up for an account with your chosen cloud provider.
3. Set Up a Server Instance: Launch a new server instance with the necessary configurations (Ubuntu is a commonly used OS for n8n installations).
4. SSH Access: Make sure you have SSH access to your server instance.

Installation Steps

1. Update the Server

Log into your server via SSH and update the package lists to ensure everything is current:

sudo apt-get update && sudo apt-get upgrade

2. Install Docker

n8n is best run within a Docker container. Install Docker on your server by running the following command:

sudo apt-get install docker.io

After installation, start Docker and enable it to run on boot:

sudo systemctl start docker
sudo systemctl enable docker

3. Deploy n8n Using Docker

Now you can deploy n8n by creating a Docker container. Use the following command:

sudo docker run -d \
  --name n8n \
  -p 5678:5678 \
  -e N8N_BASIC_AUTH_ACTIVE=true \
  -e N8N_BASIC_AUTH_USER=your_username \
  -e N8N_BASIC_AUTH_PASSWORD=your_password \
  n8nio/n8n

Note: Replace your_username and your_password with your desired credentials. This basic authentication helps secure your n8n instance.

4. Accessing n8n

Once n8n is up and running, you can access it using your server's public IP address or domain name. Open a web browser and navigate to:

http://your-server-ip:5678

If you set up HTTPS, ensure to visit the address using:

https://your-server-ip

Log in using the credentials you configured previously.

5. Setting Up HTTPS (Optional)

For improved security, it is highly recommended to set up HTTPS. You can use a tool like Let's Encrypt along with Nginx or Caddy for this purpose. Here’s a quick guide to setting it up with Nginx:

1. Install Nginx:

sudo apt-get install nginx

2. Configure Nginx:

Edit the Nginx configuration file to set up reverse proxy for n8n.

sudo nano /etc/nginx/sites-available/n8n

Add the following configuration:

server {
    listen 80;
    server_name your-domain.com;  # Replace with your domain

    location / {
        proxy_pass http://localhost:5678;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

3. Enable the Configuration:

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

4. Install Certbot for HTTPS:

Install Certbot to obtain an SSL certificate from Let's Encrypt:

sudo apt-get install certbot python3-certbot-nginx

Follow the prompts to secure your site with a certificate.
