两天前，我的运行 ubuntu 服务器（18.04）的英特尔 nuc 开始随机关闭（大约 1 小时后）。
我已经更新了所有内容，问题仍然存在。
在我的 /var/log/system 中，我可以看到以下几行，但实际上没有关闭的原因。我有什么想法可以在哪里挖掘吗？

答案1
我使用了带有 CentOS 的英特尔 NUC。有时回来，我遇到同样的问题：在不同的时间间隔后关闭。我以为是CentOS的问题，后来发现是散热问题。
我通过更新 BIOS 并在 BIOS -> Advanced -> Colling 选项卡中将风扇控制模式设置为“Balanced and Cool”来解决此问题。
另外，我还清除了所有阻碍 NUC 空气流动的垃圾文件。
希望这也适合你。
