CentOS.jpg
因为家里有台限制的电脑, 就装上CentOS系统当做服务器使用; 可是CentOS默认的关闭盖子后系统就睡眠了, 在网上查了下, 关闭盖子后正常工作
启动CentOS, 修改/etc/systemd/logind.conf 文件
vim /etc/systemd/logind.conf
文件打开是这样的:

#NAutoVTs=6
#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root
#InhibitDelayMaxSec=5
#HandlePowerKey=poweroff
#HandleSuspendKey=suspend
#HandleHibernateKey=hibernate
#HandleLidSwitch=suspend
#HandleLidSwitchExternalPower=suspend
#HandleLidSwitchDocked=ignore
#PowerKeyIgnoreInhibited=no
#SuspendKeyIgnoreInhibited=no
#HibernateKeyIgnoreInhibited=no
#LidSwitchIgnoreInhibited=yes
#HoldoffTimeoutSec=30s
#IdleAction=ignore
#IdleActionSec=30min
#RuntimeDirectorySize=10%
#RemoveIPC=no
#InhibitorsMax=8192
#SessionsMax=8192
将其中的 #HandleLidSwitch=suspend 改成 HandleLidSwitch=lock
ignore（什么都不做）
poweroff（关机）
reboot（重新启动）
halt（进程都挂起）
suspend（待机挂起）
hibernate（休眠）
lock (锁屏,任可正常工作)
因为默认是suspend 所以当关闭盖子后, 所有进程都挂起了, 远程连接也无法使用了.
最后修改完毕后, 重启或者 systemctl restart systemd-logind生效.
