[Linux] - 樹莓派 4B 安裝 .NET Core 3.x (arm64)，並設置其開機自啟動

硬件：Raspberry Pi 4B
系統：Ubuntu 19.10 (Eoan Ermine) for IOT
.Net Core 官網：https://dotnet.microsoft.com/download/dotnet-core/3.1

操作步驟

1. 系統環境准備

sudo apt-get update
sudo apt-get upgrade

2. .NET Core 3.x arm64 位安裝包下載

wget https://download.visualstudio.microsoft.com/download/pr/2ea7ea69-6110-4c39-a07c-bd4df663e49b/5d60f17a167a5696e63904f7a586d072/dotnet-sdk-3.1.102-linux-arm64.tar.gz
wget https://download.visualstudio.microsoft.com/download/pr/ec985ae1-e15c-4858-b586-de5f78956573/f585f8ffc303bbca6a711ecd61417a40/aspnetcore-runtime-3.1.2-linux-arm64.tar.gz

3. SDK 和 Runtime 安裝包解壓

mkdir dotnet-arm64
tar zxf dotnet-sdk-3.1.102-linux-arm64.tar.gz -C $HOME/dotnet-arm64
tar zxf aspnetcore-runtime-3.1.2-linux-arm64.tar.gz -C $HOME/dotnet-arm64

4. 系統環境變量設置

export DOTNET_ROOT=$HOME/dotnet-arm64
export PATH=$PATH:$HOME/dotnet-arm64

5. 這時候 .Net Core 已安裝成功，可以查看信息了

dotnet --info

 

6. .NET Core 自啟動設置

6.1 在 Ubuntu 系統中

sudo nano .profile

6.2 在 Raspbian / Debian 系統中

sudo nano .bashrc

添加環境變量啟動項

# set .NET Core SDK and Runtime path
export DOTNET_ROOT=$HOME/dotnet-arm64
export PATH=$PATH:$HOME/dotnet-arm64

 

7. 重啟系統，.NET Core 可以自啟動成功。
