首先我用armbain部署的 
打开 Release Release v1.4.2 · matrix-construct/tuwunel 
下载对应的deb 
这里我是v1.4.2-release-all-aarch64-v8-linux-gnu-tuwunel.deb 
sudo apt install ./v1.4.2-release-all-aarch64-v8-linux-gnu-tuwunel.deb 
啊，对 apt可以这么用 
然后建立一个地盘，这里为 /mnt/disk/mt 
mkdir /mnt/disk/mt
sudo adduser --system tuwunel --group --disabled-login --no-create-home
sudo chown -R tuwunel:tuwunel /mnt/disk/mt/
sudo chmod 70...
