N8N Self-Hosted Installation Guide 2025: Complete Setup + Production Configuration Reality Check

N8N is an open-source automation platform that connects apps and services using visual workflows. It’s popular for its flexibility, allowing users to self-host for complete control over data and infrastructure. But self-hosting comes with challenges - security, maintenance, and scalability require technical expertise and ongoing effort.

For businesses managing sensitive data or needing extensive customization, self-hosting N8N can be a strong option. However, the operational demands often outweigh the benefits for smaller teams or those without dedicated DevOps resources. Managed platforms like Latenode simplify automation by handling infrastructure, security, and scaling, enabling you to focus on workflows rather than upkeep.

Here’s how to evaluate if self-hosting N8N is right for you, along with a step-by-step guide for setup and tips to optimize your deployment.

Self-Host Your Own Automation Platform with n8n + Docker

Prerequisites and Infrastructure Planning

Before setting up n8n, it's crucial to evaluate your infrastructure needs carefully. Proper planning helps avoid unnecessary expenses and ensures a smooth deployment.

Infrastructure Requirements

N8n requires more memory than many standard web applications, with memory usage often outweighing CPU demands. Since it stores workflow data, execution history, and credentials in its database, the performance of your storage system plays a key role in maintaining smooth operations [1].

Minimum Production Specifications:

For a reliable setup, your server should include at least 10 CPU cores with the ability to scale as needed. While n8n doesn’t heavily rely on CPU resources, memory allocation is critical. Memory requirements range from 320 MB for basic setups to 2 GB for production environments managing multiple workflows [1]. To avoid execution delays, database storage should be between 512 MB and 4 GB, ideally on SSD drives [1].

Operating System and Database Support:

N8n can run on any infrastructure that supports Docker [1]. For testing, SQLite is sufficient, but PostgreSQL is recommended for production environments. Ensure the database is pre-created, grants full table permissions to the n8n process, and is isolated per instance [1]. If hosting multiple instances, PostgreSQL’s schema feature can provide isolation without requiring separate databases.

Network and Security Considerations:

In production, avoid exposing n8n’s default web interface (port 5678) directly to the internet. Basic database security measures, such as IP allow lists and regular backups, are essential [1]. For containerized environments, ensure the database volume is persisted and properly mounted to prevent data loss during container restarts [1].

Once infrastructure and security needs are established, assess whether your team has the technical expertise to manage these requirements.

Required Skills and Team Readiness

Successfully self-hosting n8n requires knowledge across several technical areas.

Key Skills:

• Linux system administration: Includes managing packages, configuring services, analyzing logs, and monitoring performance.
• Docker proficiency: Covers container orchestration, network configuration, volume management, and troubleshooting.
• Database management: Skills in PostgreSQL installation, tuning performance, creating backups, and optimizing queries.
• Security expertise: Encompasses SSL certificate management, firewall configuration, access control, vulnerability assessments, and incident response.
• Network administration: Includes DNS setup, load balancing, proxy configuration, and traffic monitoring.

Self-Hosting Cost Planning

When planning to self-host n8n, factor in both infrastructure and personnel costs. Infrastructure expenses include server hosting, database storage, and necessary security measures. Additionally, consider the ongoing costs of maintaining and monitoring the system, as well as managing incidents. Proper cost estimation ensures a clear understanding of the total ownership involved before moving on to the installation process.

Step-by-Step N8N Installation Guide

Setting up n8n requires careful attention to detail, as the process involves multiple layers of configuration. Issues often arise during database connections or due to incomplete security measures. Following these steps methodically will help ensure a smooth deployment.

Environment Setup

Start by preparing your Linux server for Docker. Use Ubuntu 22.04 LTS or CentOS 8 for the best compatibility.

Installing Docker and Docker Compose:

Update your system and install the necessary tools with the following commands:

<span class="hljs-comment"># Update system packages</span>
<span class="hljs-built_in">sudo</span> apt update && <span class="hljs-built_in">sudo</span> apt upgrade -y

<span class="hljs-comment"># Install Docker</span>
curl -fsSL https://get.docker.com -o get-docker.sh
<span class="hljs-built_in">sudo</span> sh get-docker.sh

<span class="hljs-comment"># Install Docker Compose</span>
<span class="hljs-built_in">sudo</span> curl -L <span class="hljs-string">"https://github.com/docker/compose/releases/download/v2.23.0/docker-compose-<span class="hljs-subst">$(uname -s)</span>-<span class="hljs-subst">$(uname -m)</span>"</span> -o /usr/local/bin/docker-compose
<span class="hljs-built_in">sudo</span> <span class="hljs-built_in">chmod</span> +x /usr/local/bin/docker-compose

Once Docker and Docker Compose are installed, set up a directory structure tailored for n8n:

<span class="hljs-built_in">mkdir</span> -p /opt/n8n/{data,database,logs,backups}
<span class="hljs-built_in">cd</span> /opt/n8n

Configuring Environment Variables:

Create a .env file to store your production settings securely:

<span class="hljs-comment"># Database Configuration</span>
DB_TYPE=postgresdb
DB_POSTGRESDB_HOST=localhost
DB_POSTGRESDB_PORT=5432
DB_POSTGRESDB_DATABASE=n8n_db
DB_POSTGRESDB_USER=n8n_user
DB_POSTGRESDB_PASSWORD=your_secure_password_here

<span class="hljs-comment"># N8N Configuration</span>
N8N_BASIC_AUTH_ACTIVE=<span class="hljs-literal">true</span>
N8N_BASIC_AUTH_USER=admin
N8N_BASIC_AUTH_PASSWORD=your_admin_password
N8N_HOST=your-domain.com
N8N_PORT=5678
N8N_PROTOCOL=https
WEBHOOK_URL=https://your-domain.com/

<span class="hljs-comment"># Security Settings</span>
N8N_ENCRYPTION_KEY=your_32_character_encryption_key
EXECUTIONS_DATA_PRUNE=<span class="hljs-literal">true</span>
EXECUTIONS_DATA_MAX_AGE=168

To protect sensitive information, adjust the file’s permissions:

<span class="hljs-built_in">chmod</span> 600 .<span class="hljs-built_in">env</span>
<span class="hljs-built_in">chown</span> root:root .<span class="hljs-built_in">env</span>

With the environment prepared, move on to configuring PostgreSQL for reliable data management.

Database Configuration

PostgreSQL acts as the backbone of n8n, storing workflow definitions, execution logs, and credentials. Proper setup and optimization are key to a stable system.

Installing and Configuring PostgreSQL:

Use the following commands to set up PostgreSQL:

<span class="hljs-comment"># Install PostgreSQL</span>
<span class="hljs-built_in">sudo</span> apt install postgresql postgresql-contrib -y

<span class="hljs-comment"># Start and enable PostgreSQL service</span>
<span class="hljs-built_in">sudo</span> systemctl start postgresql
<span class="hljs-built_in">sudo</span> systemctl <span class="hljs-built_in">enable</span> postgresql

<span class="hljs-comment"># Create database and user</span>
<span class="hljs-built_in">sudo</span> -u postgres psql << <span class="hljs-string">EOF
CREATE DATABASE n8n_db;
CREATE USER n8n_user WITH ENCRYPTED PASSWORD 'your_secure_password_here';
GRANT ALL PRIVILEGES ON DATABASE n8n_db TO n8n_user;
ALTER USER n8n_user CREATEDB;
\q
EOF</span>

Performance Optimization:

Fine-tune PostgreSQL for better performance by editing its configuration file (commonly located at /etc/postgresql/14/main/postgresql.conf):

<span class="hljs-comment"># Memory settings</span>
shared_buffers = 256MB

Backup and Disaster Recovery

A solid backup plan is essential for protecting against data loss, corruption, or system failures. Regularly back up your PostgreSQL database and persistent data volumes, storing the backups securely offsite. Automating this process and testing recovery procedures ensures your data is always safe.

Reality Check: Is Self-Hosting Worth It?

When teams set up self-hosted solutions, they often find that installation is just the tip of the iceberg. Deployment might account for about 20% of the process, but the remaining 80% involves ongoing tasks like maintenance, applying security updates, monitoring performance, and scaling.
