PVE LXC Tailscale tailscale up 报错解决

pve 安装 tailscale 客户端 

curl -fsSL https://tailscale.com/install.sh | sh

sudo tailscale up

failed to connect to local tailscaled (which appears to be running as tailscaled, pid 140299). Got error: Failed to connect to local Tailscale daemon for /localapi/v0/status; systemd tailscaled.service not running. Error: dial unix /var/run/tailscale/tailscaled.sock: connect: no such file or directory

或者出现failed to connect to local tailscaled; it doesn't appear to be running (sudo systemctl start tailscaled ?)

通过查阅发现 这是由于Linux上的 Tailscale 客户端需要访问权限/dev/net/tun才能创建tun网络设备。在容器中运行，则需要传递/dev/net/tun给容器。解决办法如下

pve shell中修改容器配置文件：

vim /etc/pve/lxc/容器id.conf

lxc.cgroup2.devices.allow: c 10:200 rwm

lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file

保存重启lxc容器 运行

sudo tailscale up
