On my server Ubuntu 10.04 with ispconfig 3.x, the rotation log file didn't work. Search, search, search on internet but nothing helped me.

 After investigating I found the solution, so let me share it with the internet community.

ISP Config 3 has a cron daily job active for that.

crontab -l

* * * * * /usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done
30 00 * * * /usr/local/ispconfig/server/cron_daily.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done

Cron_daily.sh run a  the php cron_daily.php.

The script search the log file in the client web folder, for ie example /var/www/clients/client1/web1/log/error.log. This folder is empty!

Logs are stored in /var/log/ispconfig/httpd/mydomain.com for example /var/log/ispconfig/httpd/byman.it

So to fix the problem I deleted the client log folder and created a symbolic link. Of course you need a root access.

#permission  2022-08-23 I got the same issue of log rotation and I got trouble to remove log folder: Operation not permitted. I find the solution on How To Force Forum, thx to Till

 byman.it -> /var/www/clients/client1/web1 is a symbolic file. I used it that because it's easier remeber the domain instead of the clientx webxx.

You fixed 2 problem:

1. Log File Rotation and Compressing
2. Log accessible from Client FTP. Your clients can open the log file under /web/logs folder.

 I hope this fix will help someone to save time.

- have fun -
