如何在阿里云部署Dify

发表评论

购买阿里ECS服务

Dify推荐配置

  • CPU >= 2 Core

  • RAM >= 4 GiB

经测试后，推荐配置 2核(vCPU) 4 GiB 3MB带宽即可 ，响应速度能满足日常使用要求

操作系统推荐 CentOS或Ubuntu

配置 Docker

参考官方文档

https://help.aliyun.com/zh/ecs/use-cases/install-and-use-docker-on-a-linux-ecs-instance#8dca4cfa3dn0e

以Centos系统为例，操作命令如下

ShellScript

## 更新您的包管理工具。
sudo yum -y update

## 添加阿里云源到您的实例中，这个源包含Docker软件包，方便您使用命令来安装和更新Docker。
sudo wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

## 安装Docker社区版本，容器运行时containerd.io，以及Docker构建和Compose插件。
sudo yum -y install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

## 启动Docker并设置Docker守护进程在系统启动时自动启动，这样可以确保每次系统启动时，Docker服务也会自动启动。

sudo systemctl start docker
sudo systemctl enable docker

## 通过查看Docker版本命令，验证Docker是否安装成功。

sudo docker -v

配置Docker镜像源

创建并编辑/etc/docker/daemon.json文件

ShellScript
{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "max-concurrent-downloads": 2,
  "max-concurrent-uploads": 2,
  "max-download-attempts": 15,
  "registry-mirrors": [
    "https://docker.m.daocloud.io/",
    "https://huecker.io/",
    "https://dockerhub.timeweb.cloud",
    "https://noohub.ru/",
    "https://dockerproxy.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://docker.nju.edu.cn",
    "https://xx4bwyg2.mirror.aliyuncs.com",
    "http://f1361db2.m.daocloud.io",
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "https://docker.mirrors.ustc.edu.cn"
  ]
}

安装Git环境

ShellScript
## 安装以来
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel 
yum install gcc-c++ perl-ExtUtils-MakeMaker

## 安装并验证git
yum install git 
git --version

安装Dify

克隆 Dify 代码仓库，克隆 Dify 源代码至本地环境。

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

启动 Dify

  1. 进入 Dify 源代码的 Docker 目录

    cd dify/docker

  2. 复制环境配置文件

    cp .env.example .env

  3. 启动 Docker 容器

    docker compose up -d

运行命令后，你应该会看到类似以下的输出，显示所有容器的状态和端口映射：

ShellScript

 ✔ Container docker-nginx-1           Started                                                                 7.1s

最后检查是否所有容器都正常运行：

ShellScript
docker compose ps

在这个输出中，你应该可以看到包括 3 个业务服务 api / worker / web，以及 6 个基础组件 weaviate / db / redis / nginx / ssrf_proxy / sandbox 。

ShellScript

通过这些步骤，你应该可以成功在阿里云服务器安装 Dify。

后续，可以通过配置域名关联该服务器外网IP，通过域名访问此Dify服务。
