樹莓派 4B 運行 net core 6.0 應用程式及網站

Running .NET Core 6.0 Applications and Websites on Raspberry Pi 4B

Environment Setup

Install .NET Core Dependencies

sudo apt install -y libunwind8 libunwind8-dev gettext libicu-dev liblttng-ust-dev libcurl4 libcurl4-openssl-dev libssl-dev uuid-dev unzip libgdiplus libc6-dev libkrb5-3

Download and Unzip the .NET SDK

wget https://download.visualstudio.microsoft.com/download/pr/1f85b038-9917-4d0a-8485-5dc86510eec7/a7555924fe292c6c2140893f066abe65/dotnet-sdk-6.0.100-linux-arm.tar.gz -O dotnet-sdk-linux-arm.tar.gz --no-check-certificate
sudo mkdir -p /usr/local/dotnet && sudo tar zxf dotnet-sdk-linux-arm.tar.gz -C /usr/local/dotnet

Create a Symbolic Link

sudo ln -s -f /usr/local/dotnet/dotnet /usr/local/bin

P.S. A symbolic link (also called a symlink or soft link) is a type of link file similar to a Windows shortcut. /usr/local is typically where executable programs are placed. Basically, all of Linux's built-in executables are located here.

Test dotnet

dotnet --version

Part 1: Running a .NET Core Console Application on Raspberry Pi

Create a new .NET Core console application project

Xftp is a tool that uses the SSH protocol to quickly upload files to Linux through a UI. To copy your locally built .NET Core application to the Raspberry Pi, you can easily do it with Xftp.

Switch to the newly uploaded .NET Core folder

cd NetCoreTest/

Run dotnet ConsoleApp1.dll

Part 2: Running a .NET Core Website on Raspberry Pi and Registering It as a Service to Start on Boot

Follow the same steps as for the .NET Core console application to copy the build output of your .NET Core web application to the Raspberry Pi using Xftp.

Switch to the uploaded folder and specify the URL and port number

dotnet LetGo.Label.Service.dll  --urls "http://localhost:5100;https://localhost:5101"

Finally, visit the URL

If you want the application to start automatically on boot, you can register it as a service.

sudo vim /lib/systemd/system/label.service

[Unit]
Description=Label Services
After=network.target
Wants=network.target

[Service]
Restart=on-failure
RestartSec=5
ExecStart=dotnet /var/label/LabelService.dll  --urls "http://localhost:5100;https://localhost:5101"

Start the `label` service you just registered

sudo systemctl start label.service //啟動 FRP Server 服務
sudo systemctl stop label.service //停止 FRP Server 服務
sudo systemctl restart label.service //重啟 FRP Server 服務
sudo systemctl enable label.service //開機時自動啟動 FRP Server 服務
sudo systemctl disable label.service //開機時不要啟動 FRP Server 服務
sudo systemctl status label.service //查看FRP Server 狀態
sudo systemctl is-failed label.service // 查看失敗狀態
sudo systemctl daemon-reload  // reload service
sudo systemctl status frpc.service
