前言

RustDesk 是一款开源的远程桌面工具,支持跨平台使用,并且提供了无头(Headless)模式,非常适合没有物理显示器的 Linux 服务器环境。

本文将详细介绍如何在 Linux 服务器上配置 RustDesk 的无头访问,包括系统环境准备、虚拟显示器配置以及 RustDesk 的安装与设置。通过本文的步骤,即使服务器没有显示器,也可以实现稳定的远程桌面访问,从而提升运维效率和管理便利性。

配置系统环境

整体可以参照官方Wiki: https://github.com/rustdesk/rustdesk/wiki/Headless-Linux-Support

  1. 安装桌面环境

    # Only support gnome desktop. https://www.gnome.org
    # xfce4 may be supported.
    
    # for Ubuntu
    $ sudo apt install ubuntu-desktop
    $ sudo apt install xserver-xorg-video-dummy
    $ sudo apt install lightdm
    
    # for Fedora
    $ sudo sudo yum groups install "GNOME"
    $ sudo yum install xorg-x11-drv-dummy
    
    # for archlinux
    $ pacman -S xorg xorg-server xf86-video-dummy
    $ pacman -S gnome
    
  2. 配置xorg虚拟显示器(这一步官方的文档缺失了)

    修改或创建配置文件/etc/X11/xorg.conf,填入以下配置

    Section "ServerFlags"
      Option "DontVTSwitch" "true"
      Option "AllowMouseOpenFail" "true"
      Option "PciForceNone" "true"
      Option "AutoEnableDevices" "false"
      Option "AutoAddDevices" "false"
    EndSection
    
    Section "InputDevice"
      Identifier "dummy_mouse"
      Option "CorePointer" "true"
      Driver "void"
    EndSection
    
    Section "InputDevice"
      Identifier "dummy_keyboard"
      Option "CoreKeyboard" "true"
      Driver "void"
    EndSection
    
    Section "Device"
      Identifier "dummy_videocard"
      Driver "dummy"
      Option "ConstantDPI" "true"
      #VideoRam 4096000
      VideoRam 256000
      #VideoRam 192000
    EndSection
    
    Section "Monitor"
      Identifier "dummy_monitor"
      HorizSync   5.0 - 1000.0
      VertRefresh 5.0 - 200.0
      #To add your own modes here, use a modeline calculator, like:
      #http://xtiming.sourceforge.net/cgi-bin/xtiming.pl
      #or using the "gtf" command line tool (http://gtf.sourceforge.net/)
    
      #This can be used to get a specific DPI, but only for the default resolution:
      #DisplaySize 508 317
      #NOTE: the highest modes will not work without increasing the VideoRam
      # for the dummy video card.

  3. 重新启动系统使得配置成功生效

安装配置RustDesk

  1. 先安装配置对应架构的Rust Desk:https://github.com/rustdesk/rustdesk/releases

  2. 配置启用无头访问功能

    sudo rustdesk --option allow-linux-headless Y
    
  3. 服务器一般有公网IP,可以开启公网访问

    sudo rustdesk --option direct-server Y
    # 可选,修改端口
    sudo rustdesk --option direct-access-port XXXX
    
  4. 获取Rust Desk ID、设置密码

    sudo rustdesk --get-id
    sudo rustdesk --password <password>
    
  5. 使用IP直连或者Rust Desk ID以及配置的密码连接
