服务器要求

硬件要求很低,最低配置的云服务器就可以了,CPU和内存要求都是最小的。关于网络大小,如果TCP打洞直连失败,就要耗费中继流量,一个中继连接的流量在30k-3M每秒之间(1920x1080屏幕),取决于清晰度设置和画面变化。如果只是办公需求,平均在100K/s。

步骤1:Window安装nvm

这里我们使用node版本管理工具:nvm,
Github打开慢的推荐使用下面的地址下载:https://url05.ctfile.com/f/43095505-806384372-9c3d03?p=8482 (访问密码: 8482)

Github官方下载地址:https://github.com/coreybutler/nvm-windows/releases/download/1.1.10/nvm-setup.exe

下载完成后,我们直接打开安装包,根据自己的安装路径选择下一步就可以了;安装完毕后,打开cmd命令行,输入:nvm version 如果有正确显示就代表成功。

步骤2:安装Nodejs

安装Nodejs v16.14.2这个版本,打开cmd命令行,输入安装命令:nvm install 16.14.2 ,最后等待安装完成,

安装完nodejs后,还需要使用这个版本,使用命令:nvm use 16.14.2

步骤3:安装pm2

在cmd.exe中分别输入下面三行,每一行都要按回车键,一行一行运行:

npm install -g pm2
npm install pm2-windows-startup -g
pm2-startup install

步骤4: 下载服务器端软件程序,运行hbbr和hbbs

GitHub访问不了的推荐下面地址下载:
64位下载地址:https://url05.ctfile.com/f/43095505-806384538-56e21b?p=8482 (访问密码: 8482)

32位下载地址:https://url05.ctfile.com/f/43095505-806384523-e16e1e?p=8482 (访问密码: 8482)

官方地址:
64位下载地址:https://github.com/rustdesk/rustdesk/releases/download/1.1.9/rustdesk-1.1.9-windows_x64.zip

32位下载地址:https://github.com/rustdesk/rustdesk/releases/download/1.1.9/rustdesk-1.1.9-windows_x32.zip

有两个可执行文件和一个文件夹:

  • hbbs - RustDesk ID注册服务器
  • hbbr - RustDesk 中继服务器

默认情况下,hbbs 监听21115(tcp), 21116(tcp/udp), 21118(tcp),hbbr 监听21117(tcp), 21119(tcp)。务必在防火墙开启这几个端口, 请注意21116同时要开启TCP和UDP。其中21115是hbbs用作NAT类型测试,21116/UDP是hbbs用作ID注册与心跳服务,21116/TCP是hbbs用作TCP打洞与连接服务,21117是hbbr用作中继服务, 21118和21119是为了支持网页客户端。如果您不需要网页客户端(21118,21119)支持,对应端口可以不开。

  • TCP(21115, 21116, 21117, 21118, 21119)
  • UDP(21116)

如果你想选择自己的端口,使用 “-h” 选项查看帮助,云服务器记得要把这几个端口放行

假设你解压缩到了C盘下,分别运行下面四行命令(一行一行运行):

cd c:\rustdesk-server-windows-x64
pm2 start hbbs.exe -- -r <-r hbbr运行所在主机的地址[:port]默认21117端口> 
pm2 start hbbr.exe 
pm2 save

hbbs在第一次运行时,会自动产生一对加密私钥和公钥(分别位于运行目录下的id_ed25519id_ed25519.pub文件中),其主要用途是为了客户端通讯加密。

其中id_ed25519.pub 这个文件就是客户端需要填写的key

运行完毕后,查看服务是否启用

pm2 list

重启服务器

pm2 restart hbbs
pm2 restart hbbr

停止服务

pm2 stop hbbs
pm2 stop hbbr

查看日志

pm2 log hbbr
pm2 log hbbs

到这一步,服务器已经安装好了

客户端配置

官网下载地址:https://rustdesk.com/zh/

安装好后配置中继服务,按下面的截图顺序配置就可以了:


把配置放在可执行文件名里 (Windows only)

把rustdesk.exe 修改为 rustdesk-host=<host-ip-or-name>,key=<public-key-string>.exe, 例如: rustdesk-host=192.168.1.137,key=xfdsfsd32=32.exe,你可以在About窗口看到配置结果,如下图所示。

    I like reading through a post that will make men and women think.
    Also, many thanks for permitting me to comment! Article 1: Axial Fans in Computer Cooling Systems
    Axial fans are a cornerstone in modern computer cooling systems, providing efficient airflow to dissipate heat generated by high-performance components.

    These fans operate by drawing air parallel to the
    axis of rotation, creating a high-volume, low-pressure airflow ideal for electronics.

    In personal computers, servers, and data centers, axial fans are commonly integrated into cases, CPU coolers, and graphics card assemblies.

    The primary advantage of axial fans in computer cooling lies in their ability to move large volumes of
    air with minimal noise at moderate speeds. For instance, a
    typical 120mm axial fan can push 50-80 cubic feet per minute (CFM) of air
    while operating at 1000-2000 RPM. This is crucial for maintaining optimal
    temperatures in components like processors, which can exceed 80°C under load without
    proper cooling, leading to thermal throttling or hardware failure.

    In desktop PCs, axial fans are often used in push-pull configurations.

    A front intake fan draws cool ambient air into the case, while rear exhaust fans expel hot
    air. This creates a positive pressure environment that
    reduces dust buildup. High-end gaming rigs employ multiple axial fans in radiators for liquid cooling loops, where
    fans like Noctua's NF-F12 series excel due to their optimized blade design, which
    minimizes turbulence and vibration.
    Server environments demand even more from axial fans.
    In rack-mounted systems, hot-swappable fan modules ensure redundancy; if
    one fails, others compensate without downtime.
    Data centers, housing thousands of servers, rely on axial
    fans in CRAC (Computer Room Air Conditioning) units
    to circulate air efficiently. Energy efficiency is key here—fans
    with EC (Electronically Commutated) motors adjust speed based on temperature sensors,
    reducing power consumption by up to 50% compared to AC
    motors.
    Challenges in computer cooling include noise management and space constraints.

    Axial fans can produce audible hums at high speeds,
    prompting innovations like PWM (Pulse Width Modulation) control, which allows dynamic speed adjustment.
    In laptops, miniaturized axial fans (often 40-60mm) face thermal density issues,
    where slim designs limit airflow. Engineers counter this with heat pipes and vapor chambers, but the fan remains essential for active cooling.

    Sustainability is emerging as a focus. Modern axial fans incorporate recyclable materials and low-power
    designs to align with green computing initiatives. For example, fans in Apple's
    Mac Pro use advanced aerodynamics to achieve quiet operation while cooling
    powerful Xeon processors.
    Future trends point toward smarter integration. With
    AI-driven thermal management, axial fans could self-optimize via
    machine learning, predicting heat loads from
    usage patterns. In quantum computing, where cryogenic cooling is needed, specialized
    axial fans maintain sub-zero environments.
    Overall, axial fans' versatility makes them indispensable
    in computer cooling. Their evolution from basic exhaust units to intelligent, efficient systems
    underscores their role in enabling faster, more reliable computing.
    As hardware pushes boundaries, axial fans will continue adapting, ensuring systems run cool under
    pressure. (Word count: 512)
    Article 2: Axial Fans in HVAC Systems
    Heating, Ventilation, and Air Conditioning (HVAC) systems heavily rely
    on axial fans for efficient air movement in residential, commercial, and industrial buildings.
    These fans propel air along the axis, offering high flow rates at low pressures, which is perfect for
    ducted systems where uniform distribution is essential.

    In residential HVAC, axial fans are found in central air handlers, pushing
    conditioned air through vents. A standard 14-inch axial fan might
    deliver 2000 CFM, ensuring even temperature control across rooms.
    They integrate with furnaces or heat pumps, where variable-speed models adjust based on thermostat readings, improving
    energy efficiency and reducing utility bills.

    Commercial applications, like office buildings
    or malls, use larger axial fans in rooftop units (RTUs).
    These fans exhaust stale air and intake fresh outdoor air, maintaining indoor
    air quality (IAQ). In high-occupancy spaces, demand-controlled ventilation (DCV) systems
    employ axial fans linked to CO2 sensors, ramping up airflow
    during peak times to prevent stuffiness while conserving energy.

    Industrial HVAC demands robust axial fans for harsh environments.
    In warehouses or factories, they ventilate large volumes, removing fumes and heat from
    machinery. Explosion-proof variants, with sealed motors,
    are used in chemical plants to handle volatile gases safely.
    Fans like those from Greenheck or ebm-papst feature corrosion-resistant
    blades for longevity in humid or dusty conditions.

    Energy codes, such as ASHRAE 90.1, drive innovations
    in axial fan design. Backward-curved impellers enhance efficiency,
    achieving up to 85% static efficiency. EC motors, replacing traditional
    belt-driven systems, offer precise control and lower maintenance, cutting operational costs by 30-40%.

    Noise reduction is critical in HVAC. Axial fans can generate vibrations, so anti-vibration mounts and aerodynamic blade shaping minimize decibels.
    In hospitals, low-noise fans ensure patient comfort while providing sterile air circulation.
    Sustainability integrates through smart HVAC. IoT-enabled axial fans monitor performance via
    apps, predicting failures and optimizing runtime. In green buildings, they pair with heat recovery ventilators (HRVs) to recapture energy from exhaust air.

    Challenges include pressure drops in long ducts, where
    axial fans may underperform compared to centrifugal types.

    Hybrid systems combine both for optimal results. In extreme climates, fans with heaters prevent freezing.

    Looking ahead, axial fans will evolve with building automation. AI integration could forecast weather impacts
    on ventilation needs, enhancing efficiency.
    As urbanization grows, their role in creating comfortable, healthy
    indoor spaces remains vital. Axial fans not
    only move air but sustain modern living. (Word count: 498)
    Article 3: Axial Fans in Industrial Ventilation
    Industrial ventilation systems utilize axial fans to maintain safe, productive work environments
    by removing contaminants, heat, and odors. These fans excel in applications requiring
    high airflow volumes over short distances, such as exhaust systems
    in manufacturing plants.
    In metalworking facilities, axial fans extract welding fumes
    and dust, preventing respiratory issues. A 24-inch fan can move 5000
    CFM, integrated into hoods above workstations.
    Compliance with OSHA standards mandates such ventilation to keep airborne particles
    below permissible exposure limits (PELs).
    Chemical industries employ axial fans in fume hoods and scrubbers.
    Corrosion-resistant models, coated with epoxy or made from fiberglass,
    handle acidic vapors. Variable frequency drives (VFDs) allow
    speed modulation, balancing airflow with energy use.
    In food processing, axial fans ensure hygiene by circulating filtered air.
    They prevent moisture buildup in bakeries or dairies, reducing mold risks.

    Stainless-steel constructions meet FDA sanitation requirements,
    with washdown capabilities for easy cleaning.

    Mining operations use axial fans for underground ventilation, supplying
    fresh air and expelling methane or dust. Booster fans along shafts maintain pressure, with ATEX-certified models
    for explosive atmospheres. Their compact design fits confined spaces, delivering flows up to 100,000
    CFM in large systems.
    Energy efficiency is paramount in industrial settings.
    Modern axial fans incorporate airfoil blades for reduced drag, achieving
    efficiencies over 70%. Pairing with sensors, they
    activate only when pollutants exceed thresholds, slashing power consumption.
    Noise and vibration control are addressed through balanced impellers and isolation pads.
    In noisy factories, this ensures worker comfort without compromising
    performance.
    Sustainability drives adoption of regenerative
    braking in fan motors, recovering energy during slowdowns.
    Recyclable materials and low-emission coatings align with
    eco-regulations.
    Challenges include handling high temperatures; fans with heat shields operate up to 500°F in foundries.
    In abrasive environments, wear-resistant liners extend lifespan.
    Future developments include predictive maintenance via AI, analyzing
    vibration data to foresee breakdowns. As industries automate,
    axial fans will integrate seamlessly, enhancing safety
    and efficiency. Their robust reliability makes them essential for industrial health.
