![如何停止 NetworkManager 并使 Ubuntu 服务器进入睡眠状态?](https://linux22.com/image/1175885/%E5%A6%82%E4%BD%95%E5%81%9C%E6%AD%A2%20NetworkManager%20%E5%B9%B6%E4%BD%BF%20Ubuntu%20%E6%9C%8D%E5%8A%A1%E5%99%A8%E8%BF%9B%E5%85%A5%E7%9D%A1%E7%9C%A0%E7%8A%B6%E6%80%81%EF%BC%9F.png)
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 syslog 文件,我发现是 networkManager 请求让主机进入睡眠状态。
以下是日志条目:

这是什么原因造成的?这是网络问题还是配置问题造成的?

答案1
以下是对我有用的方法:
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
