db-gpt安装

docker pull eosphorosai/dbgpt:latest

qwen本地模型下载

git clone https://www.modelscope.cn/Qwen/Qwen2.5-Coder-0.5B-Instruct.git

embading 模型下载

新建models目录将（Qwen2.5-Coder-0.5B-Instruct、text2vec-large-chinese）目录复制到models中

docker pull不下来建议使用轩辕镜像中下载

tuGragh安装

docker pull tugraph/tugraph-runtime-centos7:latest

docker run -d -p 7070:7070 -p 9090:9090 -p 7687:7687 -v C:/Users/work/llm/data:/var/lib/lgraph/data -v C:/Users/work/llm/log:/var/log/lgraph_log --name tugraph tugraph/tugraph-runtime-centos7 lgraph_server

进入容器修改plugin配置项
