下载docker：
官方下载方式：https://docs.docker.com/desktop/install/ubuntu/
其中 DEB package需要手动下载并传输到服务器
国内下载方式：

Ensure vm.max_map_count >= 262144:
check：
$ sysctl vm.max_map_count
Reset vm.max_map_count to a value at least 262144 if it is not:
$ sudo sysctl -w vm.max_map_count=262144
This change will be reset after a system reboot. To ensure your change remains permanent, add or update the vm.max_map_count value in /etc/sysctl.conf accordingly:
$ vm.max_map_count=262144
Clone the repo:
$ git clone https://github.com/infiniflow/ragflow.git
该步骤需要手动下载并传输，国内无法下载
Build the pre-built Docker images and start up the server:
$ cd ragflow/docker
$ chmod +x ./entrypoint.sh
$ docker compose up -d
这一步也需要手动传输或直接用用源代码build（见最后）
Check the server status after having the server up and running:
$ docker logs -f ragflow-server
The following output confirms a successful launch of the system:

In your web browser, enter the IP address of your server and log in to RAGFlow.
With the default settings, you only need to enter http://IP_OF_YOUR_MACHINE (sans port number) as the default HTTP serving port 80 can be omitted when using the default configurations.
In service_conf.yaml, select the desired LLM factory in user_default_llm and update the API_KEY field with the corresponding API key.
See llm_api_key_setup for more information.
Rebuild:
To build the Docker images from source:
$ git clone https://github.com/infiniflow/ragflow.git
$ cd ragflow/
$ docker build -t infiniflow/ragflow:dev .
$ cd ragflow/docker
$ chmod +x ./entrypoint.sh
$ docker compose up -d
卸载原有cuda和驱动

下载Vllm
https://qwen.readthedocs.io/zh-cn/latest/deployment/vllm.html
国内下载model： /Qwen2-7B-Instruct方法：
pip install modelscope
from modelscope import snapshot_download
model_dir = snapshot_download(‘qwen/Qwen2-7B-Instruct’, cache_dir=‘/home/llmlocal/qwen/qwen/’)
运行llm服务器
python -m vllm.entrypoints.openai.api_server --model /home/llmlocal/qwen/qwen/Qwen2-7B-Instruct --host 0.0.0.0 --port 8000
测试：
curl http://localhost:8000/v1/chat/completions -H “Content-Type: application/json” -d ‘{
“model”: “/home/llmlocal/qwen/qwen/Qwen2-7B-Instruct”,
“messages”: [
{“role”: “system”, “content”: “You are a helpful assistant.”},
{“role”: “user”, “content”: “Tell me something about large language models.”}
],
“temperature”: 0.7,
“top_p”: 0.8,
“repetition_penalty”: 1.05,
“max_tokens”: 512
}’
更改ragflow的MODEL_NAME = “/home/llmlocal/qwen/qwen/Qwen2-7B-Instruct” 路径在rag里的chat_model
