Case Study: Enterprise AnythingLLM Deployment on Hostinger VPS
Executive Summary
Project: Secure, scalable AnythingLLM deployment for enterprise document processing and AI-powered knowledge management
Duration: 3 days (planning, implementation, testing)
Platform: Hostinger VPS (Ubuntu 22.04 LTS)
Domain: a26llm.orbitumai.com
Result: Production-ready AI platform with 99.9% uptime, SSL encryption, automated backups, and enterprise security features
Challenge
The organization needed a private, self-hosted AI solution for processing sensitive documents while maintaining complete data control. Key requirements included:
- Data Privacy: No third-party AI service data sharing
- Security: Enterprise-grade encryption and access controls
- Scalability: Handle multiple concurrent users and large document sets
- Reliability: 24/7 availability with automated backup systems
- Cost-Effectiveness: Avoid expensive SaaS AI platform subscriptions
Solution Architecture
Infrastructure Stack
- Server: Hostinger VPS (2GB RAM, 2 CPU cores, 50GB SSD)
- OS: Ubuntu 22.04 LTS
- Containerization: Docker & Docker Compose
- Reverse Proxy: Nginx with SSL termination
- SSL: Let’s Encrypt (Certbot)
- Firewall: UFW (Uncomplicated Firewall)
- Domain: Custom domain with DNS management
Application Configuration
- AnythingLLM: Latest stable release (mintplexlabs/anythingllm:master)
- Database: SQLite (default) with PostgreSQL upgrade path
- Vector Database: ChromaDB for embeddings
- Storage: Persistent Docker volumes
- Security: JWT authentication, signed requests, telemetry disabled
Implementation Process
Phase 1: Server Preparation (Day 1)
- Initial Setup
- Connected via SSH to Hostinger VPS
- Updated Ubuntu packages and security patches
- Created dedicated non-root user (anythingllm)
- Configured SSH security and key-based authentication
- Docker Installation
- Added official Docker repository
- Installed Docker CE and Docker Compose plugin
- Configured user permissions and service startup
Phase 2: Application Deployment (Day 1-2)
- Environment Configuration
- Created secure directory structure (/var/lib/anythingllm)
- Generated strong JWT and signing keys
- Configured environment variables for production
- Docker Compose Setup
# Key configuration highlights ports: "127.0.0.1:3001:3001" # Localhost only restart: unless-stopped # High availability cap_add: SYS_ADMIN # Required capabilities healthcheck: enabled # Monitoring - Application Testing
- Verified local accessibility (curl localhost:3001/api/ping)
- Tested container health and log output
- Validated data persistence across restarts
Phase 3: Production Hardening (Day 2-3)
- Reverse Proxy Setup
- Installed and configured Nginx
- Implemented proper headers and security policies
- Configured WebSocket support for real-time features
- Set up file upload limits (100MB)
- SSL Implementation
- Installed Certbot via Snap
- Generated Let’s Encrypt certificate
- Configured automatic renewal
- Implemented HTTPS redirect
- Security & Monitoring
- Configured UFW firewall (ports 22, 80, 443)
- Set up system optimization (file limits, memory mapping)
- Created automated backup scripts
- Implemented log monitoring and rotation
Key Technical Achievements
Security Measures
- SSL/TLS Encryption: End-to-end HTTPS with A+ SSL rating
- Firewall Protection: Minimal attack surface (3 open ports)
- Container Isolation: Docker security with capability restrictions
- Access Control: Non-root execution, limited SSH access
