如何停止 NetworkManager 让 Ubuntu 服务器进入睡眠状态？

Question

我有一个 Ubuntu 服务器实例，它会不时进入睡眠模式（平均每两个月一次）。通过查看系统日志文件，我发现是网络管理器请求使主机进入睡眠状态。

这是日志条目：

是什么原因造成的？这是网络问题还是配置问题的结果？

这对我有用：

systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

此命令禁用服务器上的睡眠模式。

如果我们想再次启用它：

systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target
