    Oct 160 views

    This guide provides step-by-step instructions for deploying AI inference frameworks on Ubuntu 24.04, covering system requirements, framework installation, model integration, web service deployment, and performance optimization. Technical professionals will gain practical knowledge for production-grade AI service implementation.

    System Requirements and Environment Setup

    Hardware Specifications

    Recommended configuration for physical servers/cloud instances:

    • CPU: 4+ cores with AVX2 support
    • RAM: 16GB DDR4 minimum
    • Storage: 50GB available space (NVMe SSD recommended)
    • Network: Gigabit Ethernet interface

    System Configuration

    Execute as root user:

    1. # System package updates
    2. apt update && apt upgrade -y
    4. # Install dependencies
    5. apt install -y curl wget git npm nodejs
    7. # Optional: Configure npm global path
    8. mkdir -p /opt/npm-global
    9. npm config set prefix '/opt/npm-global'
    10. echo 'export PATH=/opt/npm-global/bin:$PATH' >> ~/.bashrc
    11. source ~/.bashrc

    AI Inference Framework Installation

    Installation Process

    Use npm (Node.js 16+ required):

    1. # Clean previous installations
    2. rm -rf /opt/npm-global/lib/node_modules/openclaw
    3. npm cache clean --force
    5. # Install latest stable version
    6. npm install -g openclaw@latest --unsafe-perm

    Troubleshooting:

    • Permission errors: Use --unsafe-perm or sudo npm install
    • Network timeouts: Configure registry mirror:
      1. npm config set registry https://registry.npmmirror.com
    • Version conflicts: Check with npm ls -g openclaw

    Verification

    1. openclaw --version
    2. # Expected output: OpenClaw v2026.x.x
    4. openclaw doctor
    5. # Runs system diagnostics

    Pre-trained Model Integration

    Provider Configuration

    Interactive setup:

    1. openclaw config

    Configuration steps:

    1. Select “Custom Provider”
    2. Enter service name (e.g., zhipu-glm)
    3. Set API endpoint (format: https://api.service-domain/v4/chat/completions)
    4. Provide authentication key

    Configuration File:

    1. cat ~/.openclaw/config.json

    Model Parameters

    Example configuration:

    1. {
    2.   "models": {
    3.     "zhipu-glm": {
    4.       "max_tokens": 4096,
    5.       "temperature": 0.7,
    6.       "top_p": 0.9,
    7.       "frequency_penalty": 0.0,
    8.       "presence_penalty": 0.6
    9.     }
    10.   }
    11. }

    Web Service Deployment

    Service Launch

    1. # Development mode (port 3000)
    2. openclaw web
    4. # Production deployment with PM2
    5. npm install -g pm2
    6. pm2 start $(which openclaw) --name "ai-service" -- web --port 8080

    Secure Access Methods

    Option A: SSH Tunneling

    1. ssh -L 8080:localhost:8080 username@server_ip -N
    2. # Access via http://localhost:8080

    Option B: Nginx Proxy

    1. server {
    2.     listen 80;
    3.     server_name ai.example.com;
    5.     location / {
    6.         proxy_pass http://localhost:8080;
    7.         proxy_set_header Host $host;
    8.         proxy_set_header X-Real-IP $remote_addr;
    9.     }
    10. }

    Access Control

    Security configuration example:

    1. {
    2.   "security": {
    3.     "auth_enabled": true,
    4.     "allowed_ips": ["192.168.1.0/24"],
    5.     "api_key": "your-custom-key"
    6.   }
    7. }

    Performance Optimization

    Monitoring Tools

    1. # System monitoring
    2. apt install -y htop nmon
    4. # Framework metrics
    5. openclaw metrics --port 9090

    Optimization Techniques

    1. GPU Acceleration:

      1. apt install -y nvidia-cuda-toolkit
      2. export OPENCLAW_ENGINE=cuda

    2. Concurrency Control:

      1. {
      2.   "concurrency": {
      3.     "max_requests": 10,
      4.     "queue_size": 20
      5.   }
      6. }

    Troubleshooting Guide

    Common Issues

    Error Solution
    502 Bad Gateway Verify backend service status
    ECONNREFUSED Check port configuration
    403 Forbidden Review IP whitelist settings
    Model timeout Increase timeout parameter

    Log Analysis

    1. # View framework logs
    2. tail -f ~/.openclaw/logs/main.log
    4. # Enable debug mode
    5. export DEBUG=openclaw:*

    This guide provides complete workflow coverage from environment setup to production deployment. Adjust model parameters and security policies based on business requirements. For enterprise deployments, consider containerization for service isolation. Regular updates through openclaw update ensure access to the latest features and security patches.
