再次观察系统休眠状态，如下：

 

 

如果重启之后，从来都没有登陆，就不会出现系统自动休眠的情况。

观察系统日志，发现类似如下的内容：

Feb 25 22:15:38 server NetworkManager[737]: <info>  [1582668938.0193] manager: sleep: sleep requested (sleeping: no  enabled: yes)

发现是触发了systemd的自动休眠功能，检查休眠功能的状态以及历史记录，如下：

$ systemctl status sleep.target

● sleep.target - Sleep

    Loaded: loaded (/lib/systemd/system/sleep.target; static; vendor preset: enabled)

    Active: inactive (dead)

      Docs: man:systemd.special(7)

Feb 24 13:18:08 xps systemd[1]: Reached target Sleep.

Feb 26 13:29:31 xps systemd[1]: Stopped target Sleep.

Feb 26 13:29:57 xps systemd[1]: Reached target Sleep.

Feb 26 13:30:19 xps systemd[1]: Stopped target Sleep.

 

普通桌面应用这个情况问题不大，但是如果是作为服务器使用的时候，我们一般远程访问系统，这个功能就会导致我们无法远程控制服务器，因此我们需要关闭这个功能。

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

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.

 

再次观察系统休眠状态，如下：

 

 

1

2

4

$ systemctl status sleep.target

● sleep.target

   Loaded: masked (Reason: Unit sleep.target is masked.)

   Active: inactive (dead)

 

发现自动休眠功能已经被关闭，不会出现自动休眠导致远程控制无法访问的情况了。
