Hi,
I just configured SquidAnalyzer, a nifty little network statistics tool
that I'm using mainly in school networks to monitor network usage.
I want to run the '/usr/bin/squid-analyzer' script once a day. I took a
peek in /etc/cron.daily, and the package already installed an
/etc/cron.daily/0squidanalyzer script.
I wanted to know at what time CentOS ran the cron.daily scripts, so I
typed crontab -l, but there was only "no cronjobs defined for root".
Here's how things look on a public Slackware64 14.0 server I administrate:
# crontab -l
...
# Run hourly cron jobs at 47 minutes after the hour:
47 * * * * /usr/bin/run-parts /etc/cron.hourly 1> /dev/null
#
# Run daily cron jobs at 4:40 every day:
40 4 * * * /usr/bin/run-parts /etc/cron.daily 1> /dev/null
#
# Run weekly cron jobs at 4:30 on the first day of the week:
30 4 * * 0 /usr/bin/run-parts /etc/cron.weekly 1> /dev/null
#
# Run monthly cron jobs at 4:20 on the first day of the month:
20 4 1 * * /usr/bin/run-parts /etc/cron.monthly 1> /dev/null
How is this handled on CentOS 7?
Cheers,
Niki
CentOS / RHEL 7 use anacron for this
[root@server~]# cat /etc/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
