I don’t know how much you understand about Linux automatic wake-up and shutdown. This article mainly introduces the implementation method of Linux automatic wake-up and shutdown. Friends who need it can refer to it. I hope it can help everyone.
1. System hibernation (crontab)
Example description (create a root scheduled task to implement scheduled shutdown at 11:15 every night):
# crontab -e -u root # m h dom mon dow command 15 23 * * * /sbin/shutdown -h now
Example description (only in Runs from Monday to Friday)
1 15 23 * * 1-5 /sbin/shutdown -h now
In addition, you can add a scheduled service directly in the /etc/crontab file
15 23 * * 1-5 root shutdown -h now
2. Wake-On-LAN
1 . Check whether Wake-On-LAN is enabled directly. The function that must be supported is g
# ethtool eth0 | grep -i wake-on Supports Wake-on: pumbg Wake-on: g
2. Start g (ps: this command may become invalid after restarting)
# ethtool -s eth0 wol g
3. Add cron to ensure that g
@reboot /usr/bin/ethtool -s eth0 wol g
has been learned after each restart? Hurry up and try it out.
