本都部署Dify

一、安装Docker以及Docker Compose

Docker安装教程：Ubuntu安装Docker
Docker Compose安装教程：Ubuntu安装DokcerCompose

二、克隆 Dify 源代码至本地

git clone https://github.com/langgenius/dify.git

三、启动Dify

cd dify/docker
cp .env.example .env
docker compose up -d

注意
如果您的系统安装了 Docker Compose V2 而不是 V1，请使用 docker compose 而不是 docker-compose。通过$ docker compose version检查这是否为情况。在这里阅读更多信息。

检查是否所有容器都正常运行

docker compose ps

包括3个业务服务api / worker / web，包括6个基础组件weaviate / db / redis / nginx / ssrf_proxy / sandbox。

四、更新Dify

cd dify/docker
docker compose down
git pull origin main
docker compose pull
docker compose up -d

==注意：同步环境变量配置 ==

如果 .env.example 文件有更新，请务必同步修改您本地的 .env 文件。
检查 .env 文件中的所有配置项，确保它们与您的实际运行环境相匹配。您可能需要将 .env.example 中的新变量添加到 .env 文件中，并更新已更改的任何值。

五、访问系统

在浏览器中输入 http://localhost 访问 Dify。

六、添加模型

本都部署Dify

七、添加自定义工具（天气查询）

使用flask搭建http服务（部署到服务器）

from flask import Flask, request, jsonify
import random

app = Flask(__name__)

@app.route('/weather', methods=['GET'])
def get_weather():
    auth_header = request.headers.get('Authorization')
    if auth_header != 'Bearer hanfangyuan':
        return {"msg": "Invalid Authorization header"}, 403
    city = request.json.get('city', None)
    if city is None:
        return jsonify({
            'status': 'error',
            'errorInfo': 'No city provided',
            'data': None
        })

    # 随机生成温度，风速和风向
    temperature = f'{random.randint(10, 20)}℃'
    windspeed = f'{random.randint(1, 5)}级'
    winddirect = random.choice(['北风', '南风', '西风', '东风'])  # 随机选择风向
    # 返回JSON格式的响应
    # return jsonify({
    #     'status': 'OK',
    #     'errorInfo': None,
    #     'data': {
    #         'city': city,
    #         'temp': temperature,
    #         'windspeed': windspeed,
    #         'winddirect': winddirect
    #     }
    # })
    # 返回对LLM友好的字符串格式的响应
    return f"{city}今天是晴天，温度{temperature}, 风速{windspeed}, 风向{winddirect}"

if __name__ == '__main__':
    app.run(host='0.0.0.0',debug=False, port=4397)

测试接口（使用的Apifox）
生成openapi schema

curl --location --request POST 'http://服务器地址:4397/weather' 
--header 'Authorization: Bearer hanfangyuan' 
--header 'User-Agent: Apifox/1.0.0 (https://apifox.com)' 
--header 'Content-Type: application/json' 
--data-raw '{
    "city": "太原"
}'

利用gpt4把curl命令转为openapi schema，代码如下

                  }
                }

在Dify中添加自定义工具
使用工具

本都部署Dify

调试完成后进行发布

常见问题

nginx容器无法启动：（查看本地是否已经启动nginx服务）
- 停止本地nginx服务
- 修改本地nginx监听的端口
- 修改dify环境变量.env.local中的nginx端口
docker compose无法拉取代码
修改/etc/dokcer/daemon.json文件，配置镜像
