Alpine 上的 Wireguard：启动后自动挂载 wg0

我在 Alpine 服务器上安装了 wireguard。它正常工作，但当我重新启动服务器时，我不得不手动执行 wg-quick up wg0

wireguard:~# wg show
wireguard:~# wg-quick up wg0
[#]
[#] ip link add wg0 type wireguard
[#] wg setconf wg0 /dev/fd/63
[#] ip -4 address add 10.6.6.1/24 dev wg0
[#] ip link set mtu 1420 up dev wg0
[#] ip -6 route add fd9f:6666::1/128 dev wg0
[#] iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
wireguard:~# wg show
interface: wg0
  public key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=
  private key: (hidden)
  listening port: 51820

peer: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=
  preshared key: (hidden)
  endpoint: xx.xx.xx.xx:49323
  allowed ips: fd9f:6666::1/128, 10.6.6.2/32

我已经应用了这个文档：https://wiki.alpinelinux.org/wiki/Configure_a_Wireguard_interface_(wg)#Bringing_up_an_interface_using_wg-tools

wireguard:~# cat /etc/modules

我的错误在哪里？

答案1

没有错误，你只需要设置一个OpenRC为其提供服务。创建一个如下的初始化脚本/etc/init.d/wg-quick：

#!/sbin/openrc-run

description="WireGuard Quick"

depend() {
    need localmount
    need net
}

start() {
    wg-quick up wg0
}

stop() {
    wg-quick down wg0
}

然后运行以下命令为默认运行级别启用它：

rc-update add wg-quick default

感谢 Justin Ludwig 的回答。我没有测试您的解决方案，因为我已经设法通过/etc/network/interfaces如下修改解决了我的问题：

auto wg0
iface wg0 inet static
        address 10.6.6.1
        netmask 255.255.255.0
        post-up wg-quick up /etc/wireguard/wg0.conf
        post-down wg-quick down /etc/wireguard/wg0.conf
