Linux从零搭建Dify智能体平台（包含网络代理、docker安装、docker镜像地址设置）

news 2025/7/4 19:36:24

一、环境确认

1.1 基础要求

硬件配置
▫ CPU ≥ 2 核
▫ RAM ≥ 4 GiB
软件要求
▫ Docker ≥ 19.03
▫ Docker Compose ≥ 1.28

1.2 网络验证

验证网络连通性（代理配置示例）
export http_proxy=http://xxx.xx.xx.xxx:xxxx
curl -I www.baidu.com   # 预期返回 HTTP 200 状态码

二、环境准备

2.1 系统更新与依赖安装

yum update -y
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

2.2 Docker 全量安装

yum install -y docker-ce docker-ce-cli containerd.io  docker-buildx-plugin docker-compose-plugin
systemctl enable --now docker
docker version  # 验证输出应包含 Client 和 Server 版本信息

2.3 Docker Compose 部署

DOCKER_COMPOSE_VER="v2.24.7"
curl -L "https://github.com/docker/compose/releases/download/${DOCKER_COMPOSE_VER}/docker-compose-$(uname  -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version  # 预期输出类似 Docker Compose version 2.24.7

2.4 镜像加速与代理配置

# /etc/docker/daemon.json 
{
  "registry-mirrors": [
    "https://docker.1ms.run", 
    "https://docker.xuanyuan.me" 
  ]
}

vim /lib/systemd/system/docker.service
在[Service]模块下添加：
Environment="HTTP_PROXY=xxx.xx.xx.xxx:xxxx"
Environment="HTTPS_PROXY=xxx.xx.xx.xxx:xxxx"

systemctl daemon-reload
systemctl restart docker

三、部署实施

把dify源码传到服务器上，并进入源码所在目录：

cd /root/dify/dify-main/docker/

复制环境配置文件：cp .env.example .env
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：

最后检查是否所有容器都正常运行：
