Daily logRotate for apache at specific time

Question

How can I execute logRotate daily at a specific time (3h30) each day? Specific details on how to do this would be appreciated.

I'm on Debian.

Answer 1

Step #1 - create script

You can create a file such as this:

$ sudo gedit /etc/cron.d/logrotate

And add these lines to this file:

#!/bin/bash

/usr/sbin/logrotate /etc/logrotate.conf
EXITVALUE=$?
if [ $EXITVALUE != 0 ]; then
    /usr/bin/logger -t logrotate "ALERT exited abnormally with [$EXITVALUE]"
fi
exit 0

Step #2 - add script to crontab file

Then create a crontab entry that runs this script at 3h30 each day. To do this 2nd step edit the file /etc/crontab:

$ sudo gedit /etc/crontab

And add this line:

# m h dom mon dow user  command
30 3 * * *  root    /etc/cron.d/logrotate

NOTE: You might need to omit the user in some situations, like this:

# m h dom mon dow   command
30 3 * * *      /etc/cron.d/logrotate

Step #3 - make script executable

Lastly make the logrotate shell script (/etc/cron.d/logrotate) executable:

$ sudo chmod +x /etc/cron.d/logrotate
