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
- 1
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

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
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
{
"openapi": "3.1.0",
"info": {
"title": "Weather Service API",
"description": "API for retrieving weather data for a specified city.",
"version": "1.0.0"
},

-
在Dify中添加自定义工具
-
使用工具
- 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
"registry-mirrors": [
"https://docker.mirrors.ustc.edu.cn",
"https://registry.cn-hangzhou.aliyuncs.com",
"https://docker.m.daocloud.io",
