Self Hosted n8n di VPS Serta Setup Domain

Requirements

Pada tutorial self hosted n8n serta cara setup domainnya pastikan sudah terinstall

• Docker dan Docker Compose
• Apache
• SSL Let’s Encrypt

Konfigurasi

1. Buat folder baru dengan nama n8n-tool
2. Di dalam n8n-tool folder, buat file compose.yaml dan masukkan code berikut

 services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    ports:
      - "127.0.0.1:5678:5678"
    environment:
      - N8N_HOST=n8n.example.com
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - NODE_ENV=production
      - WEBHOOK_URL=https://n8n.example.com
      - GENERIC_TIMEZONE=Asia/Jakarta
    volumes:
      - n8n_data:/home/node/.n8n
      - ./local-files:/files

volumes:
  n8n_data:

N8N_HOST dan WEBHOOK_URL: sesuaikan dengaan domain anda

3. Kemudian buat folder local-files
4. Run sudo docker compose up -d

Setup Domain untuk n8n

1. Buat file baru di /etc/apache2/sites-available dengan nama n8n.example.com.conf

<VirtualHost *:80>
  ServerName n8n.example.com
</VirtualHost>	

2. Kemudian aktifkan virtual host dan restart Apache

sudo a2ensite n8n.example.com.conf
sudo systemctl restart apache2	

3. Buat SSL untuk n8n.example.com dengan run ini

sudo certbot --non-interactive \
-m [email protected] \
--agree-tos \
--no-eff-email \
--apache \
-d n8n.example.com \
--redirect

4. Edit konfigurasi setelah membuat SSL selesai (port 443) filenya ada /etc/apache2/sites-available/n8n.example.com-le-ssl.conf

<IfModule mod_ssl.c>
<VirtualHost *:443>
    ServerName n8n.example.com

    SSLCertificateFile /etc/letsencrypt/live/n8n.example.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/n8n.example.com/privkey.pem
    Include /etc/letsencrypt/options-ssl-apache.conf

    # Preserve original host & scheme for app logic and cookies
    ProxyPreserveHost On
    RequestHeader set X-Forwarded-Proto "https"

    # Timeouts for long webhook/flows (tune as needed)
    ProxyTimeout 600
    ProxyBadHeader Ignore

    # === Main HTTP proxy to n8n ===
    ProxyPass        /  http://127.0.0.1:5678/
    ProxyPassReverse /  http://127.0.0.1:5678/

    # === WebSocket upgrade (n8n UI uses socket.io) ===
    RewriteEngine On
    RewriteCond %{HTTP:Upgrade} =websocket [NC]
    RewriteRule /(.*)  ws://127.0.0.1:5678/$1  [P,L]

    ProxyPass        /socket.io/  ws://127.0.0.1:5678/socket.io/
    ProxyPassReverse /socket.io/  ws://127.0.0.1:5678/socket.io/
</VirtualHost>
</IfModule>

5. Kemudian restart apache sudo systemctl restart apache2
6. Selesai Buka browser dan masukkan domain n8n.example.com
