一天中特定时间终止的用户进程

一天中特定时间终止的用户进程

我正在运行 Python 脚本来获取数据并将其放入数据库中,这在 Ubuntu 20.04 headless 上可能需要一天甚至更长时间,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

每个异常也将被记录到 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)时,它似乎都会在完全相同的时间停止,即 23:36。这是最后一个日志条目(每秒生成多个日志条目)。无论脚本是在 1 小时前还是 15 小时前运行,停止时间始终相同。

在系统日志中似乎有一些可疑的东西指向了这个问题,但我不明白它是什么,因为所有相关的条目Stopping User Manager for UUID xxx似乎都与 NVidia 启动问题有关,比如, 尽管这个问题沒有答案。

编辑数据库在本地运行,没有配置备份。在我关闭所有 SSH shell 后,这种情况似乎会发生在某个任意时间,通常大约 1-2 小时。这个周末我下午停止工作时,这种情况发生在一天中的不同时间。此外,当我直接在机器上通过终端运行作业时,这种情况似乎不会发生。所以我做了所描述的事情这里,并将尝试重现该错误以查看是否有帮助。

答案1

我通常使用GNU 屏幕当我希望我的会话在关闭 SSH 会话后仍保留在服务器上时。它应该让您的会话在服务器上保持活动状态,然后防止 systemd 将其杀死。

答案2

这样做loginctl enable-linger *username*发现这里保持我的进程运行。
