我对设置cronjobs并不陌生，我正尝试在Google计算引擎中的虚拟机上进行设置。经过一番研究，我发现了这个StackOverflow问题：在虚拟机（Google云平台）中使用Cron定期运行Python脚本

I am new to setting up cronjobs and I'm trying to do it on a virtual machine in google compute engine. After a bit of research, I found this StackOverflow question: Running Python script at Regular intervals using Cron in Virtual Machine (Google Cloud Platform)

根据答案，我设法输入了 crontab -e 编辑模式并设置测试cronjob，例如 10 8 * * * / usr / bin / python / scripts / kite-data-pull / dataPull.py 。我还检查了系统时间（以UTC为单位），并据此输入了时间。

As per the answer, I managed to enter the crontab -e edit mode and set up a test cronjob like 10 8 * * * /usr/bin/python /scripts/kite-data-pull/dataPull.py. I also checked the system time, which was in UTC, and entered the time according to that.

按照答案，我应该采取的步骤是运行 sudo systemctl restart cron 正在向我抛出错误：

The step I'm supposed to take, as per the answer, is to run sudo systemctl restart cron which is throwing an error for me:

sudo systemctl restart cron System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down

关于我该怎么做的任何建议

Any suggestions on what I can do to set up this cronjob correctly?

推荐答案

使用 crontab -e 并插入一行：

* * * * * echo test123> /your_homedir_path/file.log

这将每分钟将 test123 写入文件。日志文件。

That will write test123 every minute into file.log file.

然后在 tail if 做，然后等待几分钟。您应该看到 test123 行出现在文件（和屏幕）中。

Then do tail if and wait a couple minutes. You should see test123 lines appearing in the file (and screen).

如果运行，请尝试运行python文件但首先请使用 chmod + x script.py

If it runs try running your python file but first make your .py file executable with "chmod +x script.py"
