Deploying Large Language Models on Ubuntu: Complete Guide from OpenClaw Installation to GLM Integration

    This technical guide provides a step-by-step walkthrough for deploying large language model (LLM) applications on Ubuntu systems using the OpenClaw framework, covering environment setup, model integration, performance optimization, and production deployment strategies.

    System Environment and Dependency Setup

    1.1 System Requirements Verification

    Ubuntu 24.04 LTS offers optimized support for AI frameworks. Before installation:

    • Verify system version: lsb_release -a
    • Minimum 16GB RAM recommended for inference
    • 50GB free disk space (including model files)
    • Network access to model repositories (configure proxy if needed)

    1.2 Dependency Installation

    Install core dependencies via apt:

    1. sudo apt update
    2. sudo apt install -y \
    3. python3.11-dev \
    4. python3-pip \
    5. git \
    6. cmake \
    7. build-essential \
    8. libopenblas-dev \
    9. libhdf5-dev

    NVIDIA GPU users should install CUDA 12.x and cuDNN. Verify with:

    1. nvidia-smi # Check GPU status
    2. nvcc --version # Verify CUDA version

    OpenClaw Framework Installation

    2.1 Framework Features

    OpenClaw provides three key advantages:

    • Modular architecture with plugin-based model integration
    • Automatic CPU/GPU resource optimization
    • Low-latency inference through memory pooling and batch processing

    2.2 Installation Process

    Create isolated Python environment:

    1. python3.11 -m venv openclaw_env
    2. source openclaw_env/bin/activate
    3. pip install --upgrade pip setuptools wheel
    4. pip install openclaw==0.8.2 # Latest stable version

    Verify installation:

    1. openclaw --version
    2. # Expected output: OpenClaw Framework v0.8.2

    2.3 Troubleshooting

    • Dependency conflicts: Use --ignore-installed flag
    • Permission issues: Install as non-root user
    • Network timeouts: Configure pip mirrors

    GLM Model Integration

    3.1 Model Selection Criteria

    Specification Base Version Pro Version
    Parameters 7B 65B
    GPU Memory 8GB 32GB
    Latency 300-500ms 800-1200ms
    Best For Real-time apps Complex reasoning

    3.2 Configuration Workflow

    3.2.1 Model Acquisition

    Download via framework marketplace:

    1. openclaw model download \
    2. --name glm-4.7-flash \
    3. --variant base \
    4. --output ./models

    Or manually place models in framework-compliant directory structure

    3.2.2 Configuration Wizard

    Initialize with GLM adapter:

    1. openclaw config init
    2. # Select:
    3. # 1. Model Type → LLM
    4. # 2. Framework → GLM
    5. # 3. Model Path → /path/to/glm-4.7-flash
    6. # 4. Compute Backend → auto (or cuda)

    3.2.3 Critical Parameters

    Edit config.yaml:

    1. model:
    2. max_sequence_length: 2048
    3. temperature: 0.7
    4. top_p: 0.9
    5. inference:
    6. batch_size: 8
    7. precision: fp16

    3.3 Performance Optimization

    • Memory management: Set max_concurrent_requests
    • Caching: Enable persistent KV cache
    • Quantization: 4-bit quantization for 7B models (framework-dependent)

    Service Validation

    4.1 Start Inference Service

    1. openclaw server start \
    2. --config ./config.yaml \
    3. --port 8080

    Expected output:

    1. [INFO] Server listening on port 8080
    2. [INFO] Loaded model: glm-4.7-flash (7B parameters)

    4.2 API Testing

    Send request with curl:

    1. curl -X POST http://localhost:8080/v1/completions \
    2. -H "Content-Type: application/json" \
    3. -d '{
    4. "prompt": "Explain quantum computing basics",
    5. "max_tokens": 100
    6. }'

    Sample response:

    1. {
    2. "id": "xxx",
    3. "object": "text_completion",
    4. "created": 1680000000,
    5. "model": "glm-4.7-flash",
    6. "choices": [{
    7. "text": "Quantum computing utilizes...",
    8. "index": 0,
    9. "finish_reason": "length"
    10. }]
    11. }

    4.3 Benchmark Testing

    Run framework benchmarks:

    1. openclaw benchmark run \
    2. --config ./config.yaml \
    3. --requests 100 \
    4. --concurrency 10

    Performance metrics:
    | Metric | 7B (GPU) | 65B (GPU) |
    |———————————|—————|—————-|
    | First-token latency | 280ms | 950ms |
    | Throughput | 1200 t/s | 350 t/s |
    | Memory usage | 6.8GB | 28GB |

    Advanced Applications

    5.1 Parameter-Efficient Fine-Tuning

    Implement LoRA adapter:

    1. from openclaw import LoraAdapter
    2. adapter = LoraAdapter(
    3. base_model_path="./models/glm-4.7-flash",
    4. target_modules=["query_key_value"],
    5. r=16, alpha=32
    6. )
    7. adapter.train(
    8. train_dataset="path/to/data",
    9. epochs=3,
    10. batch_size=16
    11. )

    3. type: "resnet50"
    4. pretrained: true
    5. fusion_strategy: "cross_attention"

    5.3 Production Deployment

    Docker deployment example:

    1. FROM ubuntu:24.04

    • Adjust temperature and top_p
    • Improve prompt quality
    • Set max_new_tokens limit

    6.3 Resource Overload

    • Limit concurrent requests
    • Enable dynamic batching
    • Consider model quantization
