为什么我每周的anacron工作没有执行？

Question

我想用anacron在Ubuntu13.04上每周做一次工作。

这是我的/etc/crontab：

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user  command
17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 5   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
#

这是我的/etc/anacrontab：

# /etc/anacrontab: configuration file for anacron

# See anacron(8) and anacrontab(5) for details.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
HOME=/root
LOGNAME=root

# These replace cron's entries
1   5   cron.daily  run-parts --report /etc/cron.daily
7   10  cron.weekly run-parts --report /etc/cron.weekly
@monthly    15  cron.monthly    run-parts --report /etc/cron.monthly

这是我的/etc/cron.Week/0 0anacron：

#!/bin/sh
#
# anacron's cron script
#
# This script updates anacron time stamps. It is called through run-parts
# either by anacron itself or by cron.
#
# The script is called "0anacron" to assure that it will be executed
# _before_ all other scripts.

test -x /usr/sbin/anacron || exit 0
anacron -u cron.weekly

最后，这里是我输入的脚本/etc/cron.Week/：

#!/bin/sh
curlftpfs -o allow_other,skip_pasv_ip mauro-casa.no-ip.org:21001/Volume_1/Foto/Marta/ /home/mauro/Pubblici/Marta_NAS/
sleep 5
rsync -rlt --update --ignore-existing --size-only --exclude=.picasaoriginals/* --exclude=.picasaoriginals --exclude=.directory --exclude=.dropbox --exclude=picasa.ini --temp-dir=/home/mauro/.rsync-temp/ /home/mauro/Dropbox/Marta/ /home/mauro/Pubblici/Marta_NAS/
umount -l /home/mauro/Pubblici/Marta_NAS/

这个脚本显然是chmoded +x，如果手动执行它(使用sudo)，它工作得很好。

编辑#1

按照要求，这里的输出

cat /var/log/cron.log | grep "Oct 13"

Oct 13 08:29:05 mauro-alienware anacron[1315]: Anacron 2.3 started on 2013-10-13

似乎没有显示cron.weekly的日志。

相反，下面是cat /var/log/cron.log.1 | grep "Oct 11"输出的摘录：

Answer 1

您没有发布要运行的脚本的实际名称，但是它很可能包含一个点('.')，就像它以‘..sh’结尾一样。

run -部件将不运行除了字母、数字字符或连字符以外的其他任何内容的脚本。去掉点，你就没事了。

Answer 2

anacron什么时候运行

？

通常，anacron不作为守护进程运行。在基于Debian的系统上，它与/etc/cron.d/anacron的经典cron一起运行。它也在系统启动后开始，从睡眠中恢复并改变电源管理状态。

您可以检查最后一次使用sudo cat /var/spool/anacron/cron.weekly运行anacron作业的日期。

Answer 3

cat /etc/cron.d/anacron

将告诉您anachron将运行的时间和时间，例如：

# /etc/cron.d/anacron: crontab entries for the anacron package

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

30 7    * * *   root    start -q anacron || :

向你展示它每天早上7:30运行，但每周只运行一次。它检查写入的日期。

sudo cat /var/spool/anacron/cron.weekly

(如果日期较旧，它将启动并更新该文件中的日期)
