群晖虚拟机OpenWRT配置Taiscale

1. Extract the contents of root to your filesystem root:

tar x -zvC / -f openwrt-tailscale-enabler-.tgz

2. Install the prerequisites for wget and tailscale:

opkg update
opkg install libustream-openssl ca-bundle kmod-tun

3. Run tailscale for the first time:

/etc/init.d/tailscale start
tailscale up --accept-dns=false --advertise-routes=10.0.0.0/24

后面会下载对应系统的Tailscale,然后分配网站，然后复制打开对应网站，绑定tailscale账号，显示sussess即可。

最后，也是最重要的一步（否则OpenWRT重启后，Tailscale无法正常启动）：


最后保存并应用，大功造成~

遇到的问题：
OpenWRT配置Taiscale后，开机启动后Taiscale无法正常启动。
原因:下载的Taiscale版本不对。

在启动tailscale时，检测到新的版本，并且是amd64的版本，很大可能是版本跟自己本地下载的不匹配，新下载的版本放在/tmp目录下。
这时候需要把新下载的tailscaled 替换掉本地的/usr/bin/tailscaled

cp /tmp/tailscaled /usr/bin/tailscaled 
reboot
