1.确定服务器是否支持远程开机
- [root@ncapp ~]# ethtool eth0
- Settings for eth0:
- Supported ports: [ TP ]
- Supported link modes: 10baseT/Half 10baseT/Full
- 100baseT/Half 100baseT/Full
- 1000baseT/Full
- Supported pause frame use: Symmetric
- Supports auto-negotiation: Yes
- Advertised link modes: 10baseT/Half 10baseT/Full
- 100baseT/Half 100baseT/Full
- 1000baseT/Full
- Advertised pause frame use: Symmetric
- Advertised auto-negotiation: Yes
- Speed: 1000Mb/s
- Duplex: Full
- Port: Twisted Pair
- PHYAD: 1
- Transceiver: internal
- Auto-negotiation: on
- MDI-X: Unknown
- Supports Wake-on: pumbg
- Wake-on: g
- Current message level: 0x00000007 (7)
- drv probe link
- Link detected: yes
- [root@ncapp ~]#
可以看到，ethtool把网卡的信息全部列出，我们只关心其中的这两项:
- Supports Wake-on: pumbg
- Wake-on: d
如果 wake-on 一项值为 d,表示禁用wake on lan
值为 g,表示启用 wake on lan
因为此机器禁用了 wake on lan,所以用下面的命令来启用它:
[root@localhost lhd]# ethtool -s eth0 wol g
再用 ethtool命令进行查看,会发现:
Wake-on: g
2.得到目标主机的IP地址和MAC地址
- [root@ncapp ~]# ifconfig

3.准备好远程开机软件
在局域网中另一台电脑上安装远程开机软件
从以下网站下载https://www.depicus.com/wake-on-lan/wake-on-lan-cmd
Wolcmd.zip文件
解压到指定的目录下，比如，本文指定的C盘根目录。
4.远程开机
以上是帮助
如要开192.168.150.245这台机器，命令如下：
wolcmd 1c1b0d02e587 192.168.150.245 255.255.255.0 8900
