[Linux] - 树莓派 4B 安装 .NET Core 3.x (arm64)，并设置其开机自启动

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

操作步骤

1. 系统环境准备

sudo apt-get update
sudo apt-get upgrade

2. .NET Core 3.x arm64 位安装包下载

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 安装包解压

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. 系统环境变量设置

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

5. 这时候 .Net Core 已安装成功，可以查看信息了

dotnet --info

6. .NET Core 自启动设置

sudo nano .profile

添加环境变量启动项

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

7. 重启系统，.NET Core 可以自启动成功。
