发送每周电子邮件通知的解决方案的另一端 "I was able to send the automatic email notifications comfortably through kronos, django-celery with rabbitmq broker. But I would like to make the task as simple as possible with crontab."
非常感谢指导提前致谢
也许 this 可以帮助您解决 cron 抛出的后缀错误：
一个可能的解决方案是重新配置 postfix。可以使用以下命令重新配置：
sudo dpkg-reconfigure postfix
将显示用户界面。在每个屏幕上，select 以下值：
- 好的
- 互联网站
- NONE
- mail.example.com
- mail.example.com、localhost.localdomain、本地主机
- 没有
- 127.0.0.0/8, 192.168.0/24
- 是
- 0
- +
- 全部
您可能需要编辑 /etc/postfix/main.conf 以更新邮件主机名。
最后，我能够通过将 crontab 重新编辑为
来解决 crontab 中发送电子邮件通知的前三个步骤
$*/1 * * * * /home/praneeth/wru-pam/venv/bin/python3.4 /home/praneeth/wru-pam/pam_site/manage.py notify_about_changes --settings=project.settings.development
我还发现第 4 步和第 5 步不是检查 crontab 日志状态的正确方法。
我有一个 django 项目，其中有一项任务是每周向所有用户发送电子邮件通知。以下是方法步骤：-
1.Created 用于发送每周电子邮件通知的管理命令。
2.edited crontab 如下：-
$ sudo crontab -e
#For testing purposes I have edited as below
1 * * * * pathto/virtualenv pathto/manage.py notify_email
3.restarted crontab
$sudo service cron restart
cron stop/waiting
cron start/running, process 16218
4.to 检查日志状态我试过下面
$tail -n 10 /var/log/syslog
