服务器ubuntu 20.04关闭自动休眠模式

农场运维

ubuntu图形界面中无论怎么设置，系统还是会自动休眠挂机，直到碰到了如下的方法:

1.查看是否开启休眠模式
systemctl status sleep.target
发现如下所示：
● sleep.target - Sleep
Loaded: loaded (/lib/systemd/system/sleep.target; static; vendor preset: enabled)
Active: inactive (dead)
Docs: man:systemd.special(7)

  1. 执行关闭休眠功能的命令，如下：
    sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
    可以看到系统返回：
    Created symlink /etc/systemd/system/sleep.target → /dev/null.
    Created symlink /etc/systemd/system/suspend.target → /dev/null.
    Created symlink /etc/systemd/system/hibernate.target → /dev/null.
    Created symlink /etc/systemd/system/hybrid-sleep.target → /dev/null.

  2. 观察系统休眠状态，如下：
    systemctl status sleep.target
    可以看到自动休眠模式已被关闭：
    ● sleep.target
    Loaded: masked (Reason: Unit sleep.target is masked.)
    Active: inactive (dead)
