   vi /etc/logrotate.d/cactilog
   

3. Insert the following code:

   /var/www/html/cacti/log/cacti.log {
       daily
       rotate 7
       copytruncate
       compress
       notifempty
       missingok
   }

What just happened?

You just created a configuration file for logrotate to manage the Cacti log. The settings you entered will make sure that logrotate will rotate the file on a daily basis, keeping 7 days worth of logs and compressing the old files at the same time. Logrotate will not rotate the file if it is empty and will also not throw an error if the file is missing.
