Hands-On Guide: Deploying vLLM and Open-WebUI on Private GPU Servers for Fast Private AI

Executive Briefing

Synthesized and verified with editorial-team

“Leverage vLLM with PagedAttention to serve Llama 3.3 and DeepSeek at 4x traditional inference speeds with zero data egress.”

Key Takeaways

  • 1.Increases inference throughput by 4-8x via proprietary PagedAttention memory paging.
  • 2.Supports Tensor Parallelism to seamlessly shard large 70B models across multiple GPUs.
  • 3.100% drop-in compatible with standard OpenAI API endpoints.

Bảo mật dữ liệu (Data Privacy) và kiểm soát hoàn toàn hạ tầng tính toán là ưu tiên số một của các tổ chức doanh nghiệp trong năm 2026. Thay vì phụ thuộc vào các API đám mây công cộng tiềm ẩn nguy cơ rò rỉ bí mật kinh doanh, bài viết này sẽ hướng dẫn bạn chi tiết từng bước xây dựng một cụm máy chủ suy luận vLLM kết hợp giao diện Open-WebUI chuyên nghiệp.

Bước 1: Chuẩn bị Môi trường Máy chủ và Driver NVIDIA

Đảm bảo máy chủ của bạn đã cài đặt Ubuntu 24.04 LTS hoặc 22.04 LTS với NVIDIA Driver phiên bản tối thiểu 550+ và CUDA Toolkit 12.4+.


# Kiểm tra GPU nhận diện
nvidia-smi

# Cài đặt môi trường ảo Python 3.11+
python3 -m venv vllm-env
source vllm-env/bin/activate
pip install --upgrade pip
pip install vllm torch

Bước 2: Khởi chạy vLLM Server với Tensor Parallelism

Dưới đây là lệnh khởi chạy mô hình Llama-3.3-70B-Instruct tối ưu hóa trên cấu hình 2 GPU RTX 4090 hoặc 2 GPU A100:


vllm serve meta-llama/Llama-3.3-70B-Instruct   --tensor-parallel-size 2   --gpu-memory-utilization 0.95   --max-model-len 32768   --port 8000   --api-key your_super_secret_token

Bước 3: Kết nối Open-WebUI qua Docker

Triển khai giao diện Open-WebUI với một lệnh Docker duy nhất để có ngay trải nghiệm như ChatGPT nhưng chạy hoàn toàn trên server nội bộ của bạn:


docker run -d -p 3000:8080   -e OPENAI_API_BASE_URL="http://host.docker.internal:8000/v1"   -e OPENAI_API_KEY="your_super_secret_token"   -v open-webui:/app/backend/data   --name open-webui   --add-host=host.docker.internal:host-gateway   --restart always   ghcr.io/open-webui/open-webui:main

Google says students in schools that ban AI won't have access to Search

# Google says students in schools that ban AI won't have access to Search Gotta get those AI user numbers up somehow. Google seems to have shoved as many AI features into as many of its products as it can over the last few years in an attempt to justify the tens of billions of dollars it has plowed into the technology. It appears to be making another attempt to bump up its AI user numbers by issuing an ultimatum to schools: enable AI...
