Installation

Prepare a fresh server

Ensure the server has a clean EL9/EL10 installation without other panels or web servers.
Run the install script
Terminal window
```
curl -fsSL https://raw.githubusercontent.com/web-casa/LLStack/main/scripts/install.sh | sudo bash
```
Installation takes about 3-5 minutes and automatically installs:
- LiteHttpd (web server)
- Python 3.12 + Flask (panel backend)
- acme.sh (SSL certificate management)
- restic (incremental backup)
- wp-cli (WordPress CLI)
Access the panel

Open your browser and navigate to:
```
https://your-server-ip:30333
```
Complete the Setup Wizard

First-time access launches the setup wizard:
- Set admin username and password
- Choose database engine (MariaDB / PostgreSQL / None)
- Configure panel SSL certificate
- Install PHP versions
- Set server timezone
- Configure Swap (recommended for servers with less than 2 GB RAM)
- Set ACME email for SSL certificate notifications
- Panel SSL certificate setup
- PHP extensions (advanced option for selecting additional modules)
The wizard also automatically installs:
- WP-CLI for WordPress command-line management
- dnf-automatic for automatic security updates

What’s Next

Architecture

Browser → LiteHttpd :30333 (HTTPS)
            ├── /api/*  → gunicorn :8001 (Flask backend)
            ├── /ws/*   → gunicorn :8001 (WebSocket terminal)
            └── /*      → dist/ (React frontend static files)

The panel uses SQLite (WAL mode) for configuration storage. All system operations execute through shell scripts + sudo, following the principle of least privilege.
