PVE 配置 WOL 网络唤醒

WOL 网络唤醒

1. 安装 ethtool 工具

apt install ethtool

2. 查看网卡名称 ip a

3. 查看网卡信息

ethtool eth0

4. 观察 Supports Wake-on 与 Wake-on

TIP

supports wake-on 判断该网卡是否支持 WOL 唤醒，若值为 pumbg 则表示支持 WOL

Wake-on 值为 d 则表示 WOL 禁用状态，g 则为开启，PVE 默认为 d

        Link detected: yes

5. 开启 WOL 网络唤醒

ethtool -s eth0 wol g

开机运行

由于每次开机时，Wake-on 的值都会重置为 d，因此需要在开机时自动运行开启 WOL 的命令

1. 编辑 /etc/rc.local 文件

#!/bin/bash
ethtool -s eth0 wol g

exit 0

2. 赋予运行权限

chmod +x /etc/rc.local

3. 重启并按上一步骤查看 Wake-on 是否自动在开机时自动修改为 g 即可
