About how to implement automatic wake-up and shutdown in Linux

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.
