无法启动 cron 服务

几天前，我添加了一个 cronjob crontab -e，它应该每 6 小时运行一次，但我注意到 cron job 不起作用。当我手动执行脚本时，它可以工作，它应该将一些数据写入文件，这样我就可以知道它是否有效。为了找出问题所在，我执行了这个命令：service cron status我得到了这个：

Redirecting to /bin/systemctl status  cron.service
● cron.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

当我执行service cron start时我得到了这个：

Redirecting to /bin/systemctl start  cron.service
Failed to start cron.service: Unit cron.service failed to load: No such file or directory.

有人可以提示我该怎么做吗，我不是这方面的专家。

谢谢

编辑：输出来自service crond status：

我的命令是最后一个

由于显示的信息不多，我猜测应该运行的脚本的权限存在问题，您配置了错误的作业或指定了错误的路径。

如果您不想测试所有这些，而更喜欢简单快捷的方式，请阅读<user executing cron>的本地邮件，您就会看到错误。
