在一天中特定时间终止的用户进程

Question

我正在运行python脚本，获取数据并将其放到一个数据库中，在Ubuntu20.04上花费一天甚至更长时间，如下所示：

stdbuf -o0 -e0 -i0 /path/v3_start_fetch.sh >> /path/logs/v3_cronlog_start_fetch__`date +\%Y\%m\%d\%H\%M\%S`___.log 2>&1 &

剧本：

. /path/env_project_auto/bin/activate

cd  /path/working_scripts

python -u v3_updater_direct.py

每个异常都将被记录到MySQL数据库中。

问题:每次我运行任何脚本(我尝试了几个不同的脚本)，它似乎完全在同一时间停止，即23:36。有最后一个日志条目(日志条目每秒多个)。不管脚本是在前一个小时还是15个小时前运行，停止时间总是一样的。

在syslog中，似乎有一些可疑的东西指向问题，但我无法理解它是什么，因为关于Stopping User Manager for UUID xxx的所有条目似乎都与NVidia引导问题(如这 )有关，而这个问题则没有答案。

编辑数据库正在本地运行，没有配置备份。在我关闭所有SSH外壳之后，它似乎发生了一些任意的时间，通常在1-2小时左右。这件事发生在完全不同的时间，在这个周末下午我停止工作的日子里。而且，当我通过终端直接在机器上运行作业时，这种情况似乎不会发生。因此，我做了描述的这里，并将尝试再现这个bug，看看它是否有帮助。

Answer 1

执行此操作，loginctl enable-linger *username*发现这里使我的进程保持运行。

Answer 2

当我希望会话在服务器上持久存在时，即使在关闭SSH会话之后，我通常也使用GNU屏幕。它应该使您的会话在服务器上保持活动，然后防止系统杀死它。
