System Requirements and Prerequisites

Linux Mint 22 System Requirements

Minimum hardware specifications include 4GB RAM, though 8GB provides optimal performance for concurrent users. Processor requirements specify dual-core CPU at 2GHz or higher for responsive operation. Storage needs vary based on bookmark volume, with 20GB minimum recommended for system and application files.

Network connectivity requirements include stable internet access for initial installation and content preservation. Bandwidth considerations depend on bookmark frequency and content complexity. Local network access suffices for internal-only deployments after initial setup.

Graphics requirements remain minimal, as Linkwarden operates primarily through web interfaces. Hardware acceleration benefits screenshot generation but isn’t essential for core functionality.

Software Prerequisites

Essential packages include curl, wget, and git for downloading installation files and managing repositories. Text editors like nano or vim enable configuration file modification. Package management tools ensure dependency resolution and system updates.

Docker containerized installation requires Docker Engine and Docker Compose. These containerization tools simplify deployment and dependency management. Alternative manual installation needs Node.js runtime environment and Yarn package manager.

Database requirements specify PostgreSQL for data storage. Meilisearch provides full-text search capabilities. These dependencies are automatically managed in Docker installations but require manual configuration otherwise.

User Permissions and Access

Administrative privileges through sudo access enable system-level package installation and service management. User account configuration affects security and file permissions. Non-root operation enhances system security while maintaining functionality.

Network port availability requires checking for conflicts on default port 3000. Firewall configuration may need adjustment for external access. Local-only deployments avoid network security considerations.

Pre-Installation Preparation

System Updates and Security

Begin by updating Linux Mint 22 package repositories to ensure access to latest software versions:

sudo apt update && sudo apt upgrade -y

Install essential security updates and development tools:

sudo apt install curl wget git ufw fail2ban -y

Configure UFW firewall for basic protection:

sudo ufw enable
sudo ufw allow ssh
sudo ufw allow 3000/tcp

These commands establish a secure foundation for Linkwarden installation. Regular updates maintain system security and compatibility.

Directory Structure and Planning

Create a dedicated directory structure for organized file management:

mkdir -p ~/linkwarden/{data,config,backups}
cd ~/linkwarden

Plan storage locations based on expected bookmark volume. Consider separate partitions for data storage if managing large content volumes. Document directory locations for future maintenance and backup procedures.

Set appropriate permissions for security:

chmod 755 ~/linkwarden

Network Configuration

Verify port 3000 availability:

netstat -tlnp | grep :3000

If the port shows as in use, either stop the conflicting service or configure Linkwarden to use an alternative port. Document the chosen port for consistent access.

For production deployments, consider domain name configuration and SSL certificate preparation. Local testing can proceed with IP address access initially.

4. Update tags and collections as needed

Popular import sources include browser bookmarks, Pocket, Instapaper, and other bookmark managers. The import process preserves original organization while enabling Linkwarden’s enhanced features.

Security Hardening and Best Practices

Authentication and Access Control

Implement strong password policies requiring complex passwords for all user accounts. Consider integrating with existing authentication systems through LDAP or Active Directory when available.

Enable account lockout protection after multiple failed login attempts. This prevents brute force attacks while maintaining legitimate user access. Configure reasonable lockout durations balancing security and usability.

Regularly audit user accounts and permissions. Remove inactive accounts and adjust permissions based on changing organizational needs. Document access control decisions for compliance and security reviews.

Monitor authentication logs for suspicious activity patterns. Unusual login times, geographic locations, or failed attempt clusters may indicate security threats requiring investigation.

Network Security Configuration

Configure firewall rules restrictively, allowing only necessary network access:

sudo ufw deny incoming
sudo ufw allow outgoing
sudo ufw allow ssh
sudo ufw allow 3000/tcp

For production deployments, implement reverse proxy configuration using Nginx or Apache. Reverse proxies provide SSL termination, load balancing, and additional security layers.

Example Nginx configuration for SSL termination:

server {
    listen 443 ssl http2;
    server_name your-domain.com;
    
    ssl_certificate /path/to/certificate.crt;
    ssl_certificate_key /path/to/private.key;
    
    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Install and configure fail2ban for automated intrusion prevention:

sudo apt install fail2ban -y
sudo systemctl enable fail2ban

Data Backup and Recovery

Establish automated backup procedures for both database content and configuration files. Regular backups prevent data loss from hardware failures, user errors, or security incidents.

Database backup script example:

#!/bin/bash
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR="/home/backups/linkwarden"
mkdir -p $BACKUP_DIR

# Database backup
pg_dump -h localhost -U linkwarden linkwarden > $BACKUP_DIR/linkwarden_db_$DATE.sql

# Configuration backup
cp -r ~/linkwarden/.env $BACKUP_DIR/config_$DATE.env

# Cleanup old backups (keep 30 days)
find $BACKUP_DIR -name "*.sql" -mtime +30 -delete

Test backup restoration procedures regularly to ensure backup integrity and recovery capabilities. Document restoration steps for emergency situations when time-sensitive recovery is critical.
