为什么 anacron 不运行计划的任务？

  • 772

我已经设置anacron运行几个任务，但由于某种奇怪的权限错误，它似乎失败了。

这是我的anacrontab：

# /etc/anacrontab: configuration file for anacron

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

SHELL=/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
# the maximal random delay added to the base delay of the jobs
RANDOM_DELAY=45
# the jobs will be started during the following hours only
START_HOURS_RANGE=3-22

#period in days   delay in minutes   job-identifier   command
1   5   cron.daily      nice run-parts /etc/cron.daily
7   25  cron.weekly     nice run-parts /etc/cron.weekly
@monthly 45 cron.monthly        nice run-parts /etc/cron.monthly

@daily  1   bashrc.daily    rsync -aAX $HOME/.bashrc /run/media/MYUSER/samsung/home/MYUSER/.bashrc
@daily  1   bash_aliases.daily  rsync -aAX $HOME/.bash_aliases /run/media/MYUSER/samsung/home/MYUSER/.bash_aliases
@daily  5   variety.daily   rsync -aAX $HOME/.config/variety/ /run/media/MYUSER/samsung/home/MYUSER/.config/variety/
@daily  3   testfile.daily  rsync -aAX $HOME/Documents/flag.hs /run/media/MYUSER/samsung/flag.hs
@weekly 5   st_apps.daily   rsync -aAX $HOME/.local/share/Steam/steamapps/ /run/media/MYUSER/samsung/home/MYUSER/.local/share/Steam/steamapps/
@weekly 15  st_ud.daily rsync -aAX $HOME/.local/share/Steam/userdata/ /run/media/MYUSER/samsung/home/MYUSER/.local/share/Steam/userdata/
@weekly 1   anacrontab.weekly   rsync -aAX /etc/anacrontab /run/media/MYUSER/samsung/home/anacrontab

这是的输出journalctl -b --no-pager --catalog | grep anacron

jan. 14 00:02:09 MYPC anacron[73073]: Anacron started on 2022-01-14
jan. 14 00:02:09 MYPC anacron[73073]: Can't open timestamp file for job cron.daily: Permission denied
jan. 14 00:02:09 MYPC anacron[73073]: Aborted
jan. 14 00:02:42 MYPC sudo[73113]:     MYUSER : TTY=pts/0 ; PWD=/home/MYUSER ; USER=root ; COMMAND=/usr/bin/dd bs=4k of=/etc/anacrontab
jan. 14 00:02:50 MYPC sudo[73124]:     MYUSER : TTY=pts/0 ; PWD=/home/MYUSER ; USER=root ; COMMAND=/usr/bin/dd bs=4k of=/etc/anacrontab

有人可以在正确的方向上刺激我吗？

    我anacron之前工作过，但不再工作了，所以我决定采取不同的方法。为了能够在没有升级权限的情况下运行它，您需要执行以下操作：

    1. .anacron使用命令在您的主目录和两个子目录（etc和spool）中创建一个文件夹mkdir -p ~/.anacron/{etc,spool}。
    2. etc通过运行与touch $HOME/.anacron/etc/anacrontab原始/etc/anacrontab. 例如：
    # Personal anacrontab

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

#period in days   delay in minutes   job-identifier   command
@daily  1   bashrc.daily    rsync -aAXr $HOME/.bashrc /run/media/myuser/samsung/home/myuser/.bashrc
@daily  1   bash_aliases.daily  rsync -aAXr $HOME/.bash_aliases /run/media/myuser/samsung/home/myuser/.bash_aliases
    1. 在终端中，输入crontab -e并添加以下内容：
    @hourly /usr/sbin/anacron -s -t $HOME/.anacron/etc/anacrontab -S $HOME/.anacron/spool

    您可以测试等待 cron 执行每小时任务，也可以anacron通过 running 强制立即运行anacron -fnd -t $HOME/.anacron/etc/anacrontab -S $HOME/.anacron/spool/。

    希望这对将来的其他人有所帮助！
