前言

首先安装vllm，然后加载本地模型，会起一个端口好。
在安装openwebui,去访问这个端口号。下面具体步骤的演示。

一、openwebui安装

root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp# mkdir open-webui
root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp# cd open-webui/
root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# git clone https://github.com/open-webui/open-webui.git

二、配置openwebui环境

在激活虚拟环境时候，下面提示错误，让先run init，但打这个也没啥用，只需要source activate一下即可。
进入虚拟环境就安装openwebui.

root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# conda activate open-webui CondaError: Run 'conda init' before 'conda activate'root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# source activate

三、安装vllm

然后开始装vllm

(open-webui) root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# pip install vllm
Looking in indexes: http://mirrors.aliyun.com/pypi/simple

四、启动vllm

启动模型

(open-webui) root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# vllm serve /root/autodl-tmp/llm/deepseek-ai/DeepSeek-R1-Distill-Qwen-1___5B-merged
INFO 03-02 10:00:20 __init__.py:207] Automatically detected platform cuda.

INFO 03-02 10:00:20 api_server.py:913] args: Namespace(subparser='serve', model_tag='/root/autodl-tmp/llm/deepseek-ai/DeepSeek-R1-Distill-Qwen-1___5B-merged', config='', host=None, port=8000, uvicorn_log_level='info', allow_credentials=False, allowed_origins=['*'], allowed_methods=['*'], allowed_headers=['*'], api

五、启动openwebui

调用的微调模型来源
https://blog.csdn.net/weixin_41688410/article/details/145948449
配置openUI环境,因为openwebUI是默认连ollama,所以要设置为false.设置vllm启动的端口号。

(open-webui) root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# export HF_ENDPOINT=https://hf-mirror.com
(open-webui) root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# export ENABLE_OLLAMA_API=False
(open-webui) root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# export OPENAI_API_BASE_URL=http://127.0.0.1:8000/v1
(open-webui) root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# 

上述环境配好后就可以启动open-webui

(open-webui) root@autodl-container-5fd249bc19-6ec28c15:~/autodl-tmp/open-webui# open-webui serve
