Magento 2 Logrotate For Logs Getting Large

Implementing Logrotate for large log files#

The magento logs are created in /my-site-root/var/log/*.log

They are:

    -rwxrwxr-- 1 www-data www-data  19M Jun 26 08:05 debug.log
    -rwxrwxr-- 1 www-data www-data 1.1M Jun 26 08:05 exception.log
    -rwxrwxr-- 1 www-data www-data 1.6M Jun 26 08:08 magento.cron.log
    -rwxrwxr-- 1 www-data www-data 1.6M Jun 26 08:08 setup.cron.log
    -rwxrwxr-- 1 www-data www-data 228K Jun 26 08:05 system.log
    -rwxrwxr-- 1 www-data www-data 1.1M Jun 26 08:08 update.cron.log
    -rwxrwxr-- 1 www-data www-data 3.1M Jun 26 08:08 update.log

The problem is that magento 2 does not manage the deletion of these things. So the debug.log and update.log can grow really big, in order of magnitude of Gigabytes.

Implementing Logrotate#

So let us deal with this issue so we don’t have to remind ourselves to delete them from time to time

Create a file in /etc/logrotate.d/ called magento2

Add the following contents and save:

    /var/www/shooting/var/log/*.log {
        size 10M
        rotate 50
        dateformat -%Y-%m-%d-%s


  • size - when any of the *.log files become larger than 10M they are rotated
  • missingok - if there are no logs there, do not panic
  • rotate - Number of rotations to keep
  • compress + delaycompress - compress the log after rotation, but keep the most recent uncompressed.
  • notifempty - Do not logrotate if empty
  • create - Not needed as magento handles log creation
  • dateext - Add a date extension to rotated files
  • dateformat - Sets the dateformat of the dateext
