🚀 ติดตั้ง n8n ฟรี 100% | วิธีทำ Self-Host แบบมีฐานข้อมูล ไม่ต้องใช้บัตรเครดิต 2025

Introduction

This tutorial will guide you through the process of setting up n8n, a low-code workflow automation platform, using Docker Compose. You can self-host n8n for free without needing a credit card or worrying about time limitations associated with cloud versions. This setup will connect various applications like Google Sheets and Gmail, enhancing your productivity significantly.

Step 1: Prepare Your Environment

Before installing n8n, ensure your system is ready.

• Check Requirements: Confirm that your system supports Docker. You will need a compatible operating system such as Windows, macOS, or a Linux distribution.
• Install Docker and Docker Compose:
  • For Windows and macOS, download Docker Desktop from the Docker website.
  • For Linux, install Docker and Docker Compose using your package manager. For example, on Ubuntu:

    sudo apt-get update
    sudo apt-get install docker.io docker-compose
    

  • Verify the installation:

    docker --version
    docker-compose --version
    

Step 2: Create Your Docker Compose File

Next, you will create a docker-compose.yml file to define your n8n setup.

• Create a New Directory:

  mkdir n8n && cd n8n
  

• Create the docker-compose.yml File:
  • Use a text editor to create the file:

    nano docker-compose.yml
    

  • Add the following content to the file:

    version: '3'
    services:
      n8n:
        image: n8nio/n8n
        ports:
          - "5678:5678"
        environment:
          - N8N_HOST=localhost
          - N8N_PORT=5678
          - DB_TYPE=sqlite
          - DB_SQLITE_DATABASE=/data/database.sqlite
        volumes:
          - ./data:/data
    

  • Save and exit the editor.

Step 3: Start n8n

Now that your docker-compose.yml file is ready, you can run n8n.

• Run Docker Compose:

  docker-compose up -d
  

• Access n8n:
  • Open your web browser and go to http://localhost:5678.

Step 4: Update n8n and Preserve Data

Maintaining your n8n installation is crucial for performance.

• Update n8n:
  • Stop the running container:

    docker-compose down
    

  • Pull the latest image:

    docker-compose pull
    

  • Restart n8n:

    docker-compose up -d
    

• Data Preservation:
  • Ensure your docker-compose.yml file uses volumes to store data persistently. This way, your workflows and settings remain intact through updates.
