Python脚本未在crontab中执行 [英] Python script not executing in crontab

问题描述

所以我试图让我的服务器每小时执行一次Python脚本.

So I'm trying to have my server execute a Python script every hour.

当我进入目录并使用python twitter.py运行它时，它工作正常.

When I go into the directory and run it with python twitter.py, it works fine.

但是，我在crontab中有此条目，但它不起作用:

However, I have this entry in crontab and it doesn't work:

0 * * * * /run/twitterparse/twitter.py > /run/twitterparse

我试图让它每小时执行一次.

I am trying to have it execute every hour, on the hour.

以下是系统日志的输出:

Here's the output to the syslog:

Aug 5  13:00:01 localhost CRON[11474]: (root) CMD (/run/twitterparse/twitter.py >/run/twitterparse/)

Aug 5  13:00:01 localhost CRON[11473]: (CRON) info (No MTA installed, discarding output)

现在应该做的是访问数据库并将信息从Web保存到该数据库.手动运行但不自动运行时，该脚本可以达到很好的效果.

Now what it should be doing is accessing a database and saving information from the web to that database. The script does that fine when run manually, but not automatically.

推荐答案

我通过这样做解决了问题

I fixed my problem by doing this

0 * * * * python /run/twitterparse/twitter.py > /run/twitterparse

并且py文件应该是可执行文件

and the py file should be executable

chmod +x twitter.py
