最近用智能体越来越多，发现本地知识库确实有很高的实用价值。Dify作为本地知识库安装下来总体比较轻松（相较于fastgpt），基本上没有什么门槛，基本上很快可以搞定，能大大提升工作效率。

1.前置工作

首先需要安装需要的依赖：

docker，dockerdesktop，git

docker和docker compose验证方法如下

docker -v
docker compose version

有显示版本信息就是正确的

2.克隆dify到本地

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

3.拉取容器，启用

cd dify/docker
copy .env.example .env
#如果是docker compose V1则写法为docker-compose
#检查dockercompose版本方法：
#$docker compose version
docker compose up -d

4.检查是否安装后正常运行

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。

端口冲突解决方法：

在安装的过程中遇到的唯一一个问题就是端口冲突。因为之前80端口已经使用了，所以现在需要手动修改端口。其实也很简单，只需要修改.env文件即可

修改.env文件

EXPOSE_NGINX_PORT=83
#原来是80，但是端口被占用了

修改后重新运行docker compose up -d

启动器脚本

最后写了一个简单的桌面启动脚本，直接一键打开dify。如果是手动的话，每次开机需要打开dockers desktop再运行命令，总感觉很麻烦。

@echo off
chcp 65001 >nul
set "url=http://127.0.0.1:83/"
set "projectdir=C:\Users\ASUS\mywork\mydify\dify\docker"
set "dockerdesktop=C:\Program Files\Docker\Docker\Docker Desktop.exe"

echo 启动 Docker Desktop...
start "" "%dockerdesktop%"
echo 等待 10 秒让 Docker 启动...
echo %dockerdesktop%
timeout /t 10 /nobreak >nul




echo 切换目录:%projectdir%
cd /d "%projectdir%"
echo 正在启动DIFY
docker compose up -d

echo 等待5秒后启动
timeout /t 5 /nobreak >nul

start "" "%url%"

祝大家部署顺利！
