为什么我的 cron 作业执行多次? [英] why my cron job executing multiple times?

问题描述

我设置了一个需要每天执行一次的 cron 作业，但它会被执行多次.我已经按照下面提到的方式设置了它:

I have set up a cron job that need to be executed once a day but it is getting executed multiple times.I have set up it as I mentioned below:

5 8 * * * /sh_file_path

谁能告诉我为什么会发生这种情况，我应该怎么做才能解决这个问题.

Can anyone please tell me why is this happening and what should I do to resolve this problem.

推荐答案

没有更多关于您的特定设置/系统的知识，以及所有作业都被多次执行的事实，我只能推测您有多个 cron 守护进程在运行你的系统.

Without more knowledge about your particular setup/system, and the fact that all jobs get executed multiple times, I can only surmise that you have multiple cron daemons running on your system.

为cron 做一个完整的进程列表和grep(他们中的大多数在二进制文件的名称中都有这个词)，看看有多少正在运行.在标准的 linux 系统上，这应该可以工作:

Do a full process list and grep for cron (most of them have that word in the name of the binary) and see how many are running. On a standard linux system, this should work:

ps aux | grep cron

然后你必须弄清楚哪个应该运行并杀死其他人.

Then you would have to figure out which should be running and kill the others.
