fan-image-tr_menu

一键脚本

bash <(curl -sL gitee.com/meimolihan/cmdbox/raw/master/sh/fan-image-tr_menu.sh)

bash <(curl -sL ../sh/fan-image-tr_menu.sh)

补充说明

该脚本为 fan-image-tr 交互式管理菜单，集成服务启停、状态查看、开机自启管理、日志查看、能力自检、安装/卸载、数据备份/恢复等功能，操作后自动等待按键再返回菜单。

项目当前未提供 install.sh / uninstall.sh / 备份脚本，因此本菜单把这几项能力内联实现： 安装走 GitHub Releases 二进制下载（失败自动回退源码编译）+ systemd 托管，备份/恢复直接对数据目录打 tar.gz。 菜单内所有涉及服务的操作都带 sudo；选项 66 / 99 需要以 root 运行。

功能特点

• 交互式菜单：可视化操作界面，输入序号即可执行对应操作
• 服务管理：停止、启动、重启 fan-image-tr 服务
• 状态查看：查看服务运行状态、开机自启状态（含启用/禁用切换）、版本号
• 访问地址：自动从 unit 环境变量 → 启动日志 → ExecStart → MainPID 逐级回退解析访问端口
• 日志查看：查看最近100行日志，或实时跟踪日志
• 能力自检：一键执行 fan-image-tr check，输出格式支持情况与 QSV / NVENC / VAAPI 实测结果
• 运行状态与容量：执行 fan-image-tr status，输出数据 / 产物 / 上传目录占用
• 一键安装/升级：自动装 FFmpeg、创建 fit 账号、下载 Release 二进制、写入 systemd 单元并启动
• 一键卸载：停服务、删单元、删二进制，可选是否删除数据目录
• 数据管理：一键备份数据、从最新备份一键恢复（恢复前自动把原目录改名为 .bak.时间戳）
• 退场动画：退出时显示 spinner 动画
• 彩色终端输出，操作反馈清晰直观

菜单选项说明

默认路径与账号

脚本顶部「可自定义配置区」集中定义，改完重跑菜单即可生效：

注意事项

• 需要 root 权限运行（sudo 或 root 用户），选项 66 / 99 会直接校验 $EUID
• 所有 systemd 操作需系统已安装 systemctl；无 systemd 的环境请改用 dc_inst_fan-image-tr 的 Docker Compose 部署
• 项目运行强依赖 ffmpeg 与 ffprobe，选项 66 会尝试用 apt/dnf/yum/apk 自动安装
• Release 二进制名规则为 fan-image-tr-linux-{amd64|arm64}，脚本按 uname -m 自动选择
• 下载失败会回退到 git clone + go build，此时需要本机已装 Go 1.25+
• 恢复数据会覆盖现有数据，执行前会自动改名保留原目录（fan-image-tr.bak.时间戳），确认无误后可自行删除
• 备份/恢复默认目录 /vol2/1000/file/backup/fan-image-tr-backup（保留6份），如需自定义直接改脚本顶部变量
• 服务无账号密码体系，若需公网访问请自行在前面加反向代理与鉴权
• 实时跟踪日志按 Ctrl+C 退出，会自动返回菜单
• 脚本内置彩色输出，需终端支持 ANSI 转义序列
• 脚本以 bash 编写，确保运行环境支持 bash
