Linux 命令行设置关闭盖子不休眠 (服务器架设篇)

我在自己一台老旧的DELL电脑上安装了cent os7作为平常的开发服务器,这台笔记本改的服务器一直都不会关机,这时候需要:合上笔记本盖子(显示屏关闭),但是SSH远程在操作此机器,则希望合盖不睡眠(包括网络正常使用)

环境 版本
RHEL/CentOS 7.x

编辑下列文件:/etc/systemd/logind.conf

  • #HandlePowerKey按下电源键后的行为,默认power off
  • #HandleSleepKey 按下挂起键后的行为,默认suspend
  • #HandleHibernateKey按下休眠键后的行为,默认hibernate
  • #HandleLidSwitch合上笔记本盖后的行为,默认suspend(改为lock;即合盖不休眠)在原文件中,还要去掉前面的#

运行:systemctl restart systemd-logind就会生效。

附上运行演示:
