Linux 部署轻量化级Docker+Dify本地部署

一、docker二进制包下载官网下载地址访问官方下载页面 https://download.docker.com/linux/static/stable/x86_64/下载一个稳定版本我下的是docker-24.0.7.tgz。然后上传到linux中。文件大小为 69.8 MB这是正常的 Docker 二进制包大小二、解压2.1 只有几个文件很少。[aaahadoop102 docker]$sudotar-zxvfdocker-24.0.7.tgz docker/ docker/docker docker/docker-init docker/dockerd docker/runc docker/ctr docker/containerd-shim-runc-v2 docker/containerd docker/docker-proxy2.2 迁移到/opt/module下[aaahadoop102 docker]$mvdocker/opt/module/2.3 创建软链接让系统识别 Docker 命令这样以后 docker 命令就能全局使用了。[aaahadoop102 docker]$ sudo ln-s/opt/module/docker/docker/usr/bin/docker[aaahadoop102 docker]$ sudo ln-s/opt/module/docker/dockerd/usr/bin/dockerd[aaahadoop102 docker]$ sudo ln-s/opt/module/docker/containerd/usr/bin/containerd[aaahadoop102 docker]$ sudo ln-s/opt/module/docker/runc/usr/bin/runc2.4 创建 Docker 的 systemd 服务文件[aaahadoop102 docker]$sudovim/etc/systemd/system/docker.service[Unit]DescriptionDocker Application Container EngineDocumentationhttps://docs.docker.comAfternetwork-online.target firewalld.serviceWantsnetwork-online.target[Service]TypenotifyExecStart/opt/module/docker/dockerdExecReload/bin/kill-sHUP$MAINPIDLimitNOFILEinfinityLimitNPROCinfinityLimitCOREinfinityTasksMaxinfinityTimeoutStartSec0DelegateyesKillModeprocessRestarton-failureStartLimitBurst3StartLimitInterval60s[Install]WantedBymulti-user.target三、启动Docker首先进入到docker解压后的目录下# 重新加载 systemd 配置sudosystemctl daemon-reload# 启动 Dockersudosystemctl startdocker# 设置开机自启sudosystemctlenabledocker# 查看运行状态sudosystemctl statusdockerDocker 启动成功。3.2 验证[aaahadoop102 docker]$sudodocker--versionDocker version24.0.7, build afdd53b四、安装 Docker Compose独立二进制4.1 下载并迁移到/opt/module/docker 里面并改名为docker-compose[aaahadoop102 docker]$wgethttps://github.com/docker/compose/releases/download/v5.4.0/docker-compose-linux-x86_64[aaahadoop102 docker]$mvdocker-compose-linux-x86_64 /opt/module/docker/docker-compose[aaahadoop102 docker]$sudochmodxdocker-compose4.2 添加软连接[aaahadoop102 docker]$sudoln-s/opt/module/docker/docker-compose /usr/local/bin/docker-compose4.3 验证[aaahadoop102 docker]$docker-compose--versionDocker Compose version v5.4.0五、部署轻量级Dify5.1 Dify 下载地址Dify下载地址5.2 上传到Linux解压,并且移到/opt/module目录下[aaahadoop102 docker]$unzipdify-main.zip[aaahadoop102 docker]$mvdify-main /opt/module/dify5.3 进入到Dify里面的docker[aaahadoop102 docker]$cd/opt/module/dify/docker5.4 复制环境变量配置文件并修改参数轻量级可选[aaahadoop102 docker]$cp.env.example .env[aaahadoop102 docker]$grep-iMAX_WORKERS/opt/module/dify/docker/.envCELERY_MAX_WORKERS[aaahadoop102 docker]$grep-iVECTOR_STORE/opt/module/dify/docker/.envVECTOR_STOREweaviateCOMPOSE_PROFILES${VECTOR_STORE:-weaviate},${DB_TYPE:-postgresql},collaboration[aaahadoop102 docker]$grep-iREDIS_MAXMEMORY/opt/module/dify/docker/.env[aaahadoop102 docker]$vim.env修改以下参数# 限制 Worker 数量减少内存占用 MAX_WORKERS1 #
