我在我的crontab上看到这个错误：
Dec 8 09:51:01 ikeyprod cron[29245]: Error: bad username; while reading /etc/crontab 我已经validation这些命令都可以通过sudo手动推送。
-rw-r--r-- 1 root root 2.2K 2010-12-08 09:50 crontab
这些命令不运行，我不知道为什么…我看到上述错误，虽然…

您的crontab需要最后一行的用户名（mysqlcheck）。
而且：您可能想要现在更改该MySQL根密码。
问题是最后一行
0 3 * * 0 mysqlcheck -Aao –auto-repair -u root -p password > /dev/null
你错过了用户名
