本篇文章给大家分享的是有关如何进行RHEL7.2最小化安装后的电源管理配置,小编觉得挺实用的,因此分享给大家学习,希望大家阅读完这篇文章后可以有所收获,话不多说,跟着小编一起来看看吧。
公司发了个测试笔记本。 以最小化安装RHEL7.2后,发现合上笔记本盖后,系统会自动睡眠,网卡会关闭。 在网上找了一通,总算找到了解决办法。
在/etc/systemd/logind.conf 此配置文件中定义了基本电源管理项。下面是默认配置
[root@localhost ~]# cat /etc/systemd/logind.conf

#NAutoVTs=6
#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root
#InhibitDelayMaxSec=5
#HandlePowerKey=poweroff
#HandleSuspendKey=suspend
#HandleHibernateKey=hibernate
#HandleLidSwitch=suspend
#HandleLidSwitchDocked=ignore
#PowerKeyIgnoreInhibited=no
#SuspendKeyIgnoreInhibited=no
#HibernateKeyIgnoreInhibited=no
#LidSwitchIgnoreInhibited=yes
#IdleAction=ignore
#IdleActionSec=30min
#RuntimeDirectorySize=10%
#RemoveIPC=yes
#This is default for OL7.2
RemoveIPC=no
通过man 命令可以看这个文件的说明
[root@localhost ~]# man logind.conf
#...下面是部分说明
HandlePowerKey=, HandleSuspendKey=, HandleHibernateKey=, HandleLidSwitch=, HandleLidSwitchDocked=
Controls whether logind shall handle the system power and sleep keys and the lid switch to trigger actions such as
system power-off or suspend. Can be one of "ignore", "poweroff", "reboot", "halt", "kexec", "suspend", "hibernate",
"hybrid-sleep", and "lock". If "ignore", logind will never handle these keys. If "lock", all running sessions will be
screen-locked; otherwise, the specified action will be taken in the respective event. Only input devices with the
"power-switch" udev tag will be watched for key/lid switch events. HandlePowerKey= defaults to "poweroff".
HandleSuspendKey= and HandleLidSwitch= default to "suspend". HandleLidSwitchDocked= defaults to "ignore".
HandleHibernateKey= defaults to "hibernate". If the system is inserted in a docking station, or if more than one
display is connected, the action specified by HandleLidSwitchDocked= occurs; otherwise the HandleLidSwitch= action
occurs.
HandlePowerKey:按下电源键后的动作
HandleSleepKey:按下挂起键后的动作
HandleHibernateKey: 按下休眠键后的动作
HandleLidSwitch:合上笔记本盖后待机
gnore(什么都不做)
poweroff(关机)
reboot(重新启动)
halt(关机,和poweroff有什么区别,需要手动断开电源?)
kexec ( 杀死执行进程 )
suspend(待机挂起)
hibernate(休眠)
如果不想让系统在合上笔记本的时候待机,编辑/etc/systemd/logind.conf 文件,将HandleLidSwitch注释去掉,并将值修改为ignore 。然后root用户执行命令systemctl restart systemd-logind,使更改生效。
以上就是如何进行RHEL7.2最小化安装后的电源管理配置,小编相信有部分知识点可能是我们日常工作会见到或用到的。希望你能通过这篇文章学到更多知识。更多详情敬请关注亿速云行业资讯频道。
