Debian
debian7 cron.allow & cron.deny 文件
將近 3 週,在我的停機時間裡,我試圖找出文件
cron.allow
&cron.deny
在debian7發行版中的位置。沒辦法,似乎預設情況下它們不在系統中。“只是”出於強化目的,我會在我的系統中提供這些文件。我的問題實際上是我是否可以只
touch
使用它們並使用它們而不必進行其他配置。root@asw-deb:~# touch /etc/cron.allow root@asw-deb:~# touch /etc/cron.deny
或者,如果我可能必須“映射”這些文件,也許是編輯一些 cron 配置文件,“說”cron 可以在哪裡找到我創建的兩個文件。
對不起,如果我聽起來有點笨拙。
從手冊
man 1 crontab
:If the /etc/cron.allow file exists, then you must be listed (one user per line) therein in order to be allowed to use this command. If the /etc/cron.allow file does not exist but the /etc/cron.deny file does exist, then you must not be listed in the /etc/cron.deny file in order to use this command. If neither of these files exists, then depending on site-dependent configuration parameters, only the super user will be allowed to use this command, or all users will be able to use this command. If both files exist then /etc/cron.allow takes precedence. Which means that /etc/cron.deny is not considered and your user must be listed in /etc/cron.allow in order to be able to use the crontab. Regardless of the existance of any of these files, the root administrative user is always allowed to setup a crontab. For standard Debian systems, all users may use this command.
我在 Debian 7 上試了一下,它就是這樣工作的。
