- Starts the required services and enables them to run automatically after server reboots.
Phase 3 / 6 Set Up n8n with PostgreSQL
- Creates the project working directory automatically.
- Generates the Docker configuration needed to run:
- Database: PostgreSQL ready for n8n.
- n8n: The official n8n application inside Docker.
- Starts the containers automatically in the background without any manual action.
Phase 4 / 6 Configure Nginx Reverse Proxy
Creates the required Nginx configuration to route your domain to n8n, enables the configuration, and restarts Nginx automatically.
Phase 5 / 6 Issue Free SSL Certificate
- Issues a free SSL certificate from Let's Encrypt.
- Enables automatic redirection to secure HTTPS access.
Phase 6 / 6 — Success Confirmation & Success

Common Troubleshooting
SSL Certificate Issuance Failed
Cause: DNS hasn't propagated yet.
Solution: Verify with ping yourdomain.com and wait for DNS propagation.
Website Not Loading
Make sure firewall ports are open:
sudo ufw allow 80 sudo ufw allow 443
Error: port 5678 already in use
Another application is using the same port. Stop it or change the port in docker-compose.yml.
Security Recommendations
- Change the default database password (
n8npass) in~/n8n/docker-compose.ymland restart containers. - Enable Two-Factor Authentication (2FA) inside your n8n account.
- Create regular backups of the
~/n8n/directory. - Keep your server updated:
sudo apt update && sudo apt upgrade -y
Congratulations — n8n is Live!
