[英]Python script doesn't execute via crontab
I read some similar topics but no luck to fix my issue.我阅读了一些类似的主题,但没有运气解决我的问题。
This is my first Python script, it runs no problem when I manually execute it.这是我的第一个 Python 脚本,当我手动执行时它运行没有问题。
But it doesn't work with below crontab.但它不适用于以下 crontab。
0,15,30,45 * * * * /usr/bin/python /usr/lib/python3.5/venv/send_email_attachment.py >/dev/null 2>&1
I also try to below.我也尝试在下面。
*/2 * * * * /usr/bin/python /usr/lib/python3.5/venv/send_email_attachment.py > /tmp/listener.log >/dev/null 2>&1
The listener.log is generated but empty. listener.log 已生成但为空。
Any idea?任何想法? Thanks
谢谢
The form of a cronjob is: cronjob 的形式是:
* * * * * user-name command to be executed
You forgot to add the user which runs the cronjob.您忘记添加运行 cronjob 的用户。 Supposing you run it using the root user, change the code to:
假设您使用 root 用户运行它,请将代码更改为:
*/2 * * * * root /usr/bin/python /usr/lib/python3.5/venv/send_email_attachment.py > /tmp/listener.log >/dev/null 2>&1
Run this command: sudo /etc/init.d/cron restart
运行这个命令:
sudo /etc/init.d/cron restart
after setting crontab demon has to restart设置 crontab 恶魔后必须重新启动
