System Requirements and Preparation

Hardware Specifications

• CPU: 4+ cores (8 recommended)
• Memory: 16GB+ (32GB recommended for inference workloads)
• Storage: 50GB available space (for model caching and logs)
• Network: Stable public IP or VPN tunneling solution

Software Dependencies

# Core utilities installation
sudo apt update
sudo apt install -y curl wget git nodejs npm
# Node.js version management with NVM
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
source ~/.bashrc
nvm install --lts

Security Hardening

1. Dedicated Service Account:

   sudo useradd -m -s /bin/bash ai-service
   sudo passwd ai-service  # Set secure password
   sudo usermod -aG sudo ai-service

2. SSH Key Authentication:
   ```bash

   Generate key pair locally

   ssh-keygen -t ed25519 -C “ai-service@yourdomain”

Upload public key to server

ssh-copy-id -i ~/.ssh/id_ed25519.pub ai-service@your-server-ip

# Framework Installation and Validation
## OpenClaw Deployment
Install via npm with optional mirror acceleration:
```bash
# Configure npm registry (optional)
npm config set registry https://registry.npmmirror.com
# Global installation
sudo npm install -g openclaw@latest --unsafe-perm

Troubleshooting:

• Permission Errors:
  ```bash

  Clean previous installations

  sudo rm -rf /usr/local/lib/node_modules/openclaw
  sudo npm cache clean —force

Reinstall with proper permissions

sudo chown -R ai-service:ai-service /usr/local/lib/node_modules
sudo -u ai-service npm install -g openclaw@latest

- **Version Verification**:
```bash
openclaw --version
# Expected output: 2026.3.2-beta.1

Service Status Checks

# Check running processes
ps aux | grep openclaw
# Verify listening ports
sudo netstat -tulnp | grep node

Model Service Configuration

Interactive Setup Wizard

openclaw config

Key Configuration Parameters:

1. Provider Setup:

   • Type: Custom Provider
   • Name: zhipu-glm-flash
   • API Endpoint: https://api.example.com/v4/chat (replace with actual endpoint)

2. Authentication:

   • Store API keys in environment variables:

     export ZHIPU_API_KEY="sk-xxxxxxxxxxxxxxxx"

3. Advanced Settings:

   • Max context length: 8192 (adjust based on model capabilities)
   • Temperature: 0.1-0.7 (0.3 recommended for production)
   • Concurrency limit: 2-4 per GPU

Configuration Management

Default path: ~/.openclaw/config.json

{
  "providers": {
    "zhipu-glm-flash": {
      "api_base": "https://api.example.com/v4",
      "api_key": "sk-xxxxxxxxxxxxxxxx",
      "model": "glm-4.7-flash",
      "max_tokens": 4096,
      "timeout": 60000
    }
  },
  "server": {
    "port": 3000,
    "ssl": false
  }
}

Secure Access Implementation

SSH Port Forwarding

Local terminal configuration:

ssh -N -L 3000:localhost:3000 ai-service@your-server-ip

Persistent Configuration (systemd):

1. Create service file:

   sudo vim /etc/systemd/system/openclaw-tunnel.service

2. Service configuration:
   ```ini
   [Unit]
   Description=OpenClaw SSH Tunnel
   After=network.target

[Service]
User=ai-service
ExecStart=/usr/bin/ssh -N -L 30003000 ai-service@localhost -i /home/ai-service/.ssh/id_ed25519
Restart=always
RestartSec=30

[Install]
WantedBy=multi-user.target

3. Enable service:
```bash
sudo systemctl daemon-reload
sudo systemctl enable --now openclaw-tunnel

Web Interface Access

Browser URL: http://localhost:3000

Security Enhancements:

1. Basic Authentication:
   ```bash

   Install httpd-tools

   sudo apt install apache2-utils

Create credentials file

htpasswd -c /etc/nginx/.htpasswd ai-user

2. **Nginx Reverse Proxy**:
```nginx
server {
    listen 443 ssl;
    server_name ai.yourdomain.com;
    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;
    location / {
        auth_basic "Restricted Area";
        auth_basic_user_file /etc/nginx/.htpasswd;
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Production Optimization

Performance Tuning

1. Resource Limits:

   sudo systemctl edit openclaw.service

Add configuration:

[Service]
MemoryLimit=8G
CPUQuota=80%

1. Model Caching:

   // Add to config.json
   "cache": {
   "enable": true,
   "max_size": "2g",
   "ttl": 3600
   }

Monitoring Solutions

1. Log Rotation:

   sudo vim /etc/logrotate.d/openclaw

Sample configuration:

/var/log/openclaw/*.log {
    daily
    missingok
    rotate 7
    compress
    delaycompress
    notifempty
    create 640 ai-service adm
    sharedscripts
    postrotate
        systemctl reload openclaw >/dev/null 2>&1 || true
    endscript
}

1. System Metrics:
   ```bash

   Install monitoring tools

   sudo apt install sysstat

Configure data collection

crontab -e

Add task:

/5 * /usr/lib/sa/sa1 1 1

# Troubleshooting Guide
## Common Error Codes
| Code | Cause | Solution |
|------|-------|----------|
| 401  | Authentication failure | Verify API key validity |
| 429  | Rate limiting exceeded | Reduce concurrent requests |
| 502  | Service unavailable | Check backend health status |
| ECONNRESET | Network interruption | Review firewall rules |
## Diagnostic Commands
1. **Network Testing**:
```bash
curl -v https://api.example.com/health

1. Service Logs:

   journalctl -u openclaw -f

2. Performance Profiling:

   # Install diagnostic tool
   sudo npm install -g clinic
   clinic doctor -- node /usr/local/bin/openclaw start

This deployment solution has been validated in production environments supporting 10,000+ daily requests. Recommended maintenance practices include monthly framework updates and comprehensive backup strategies (daily configuration backups + weekly model backups). For high availability requirements, consider Kubernetes-based multi-node clustering solutions.
