Rotating Magento Logs

Rotating logs can help prevent log files from becoming too large and unwieldy.

To setup Logrotate to automatically rotate Magento logs:

  1. Create a directory outside of the webroot to hold the config files: 

    mkdir /srv/etc/
mkdir /srv/etc/logrotate

  2. Create a logrotate.conf file with the following content:

    /srv/public_html/var/log/*.log {
    su magemojo magemojo 
    daily                
    missingok            
    rotate 30            
    compress  
    delaycompress 
    notifempty    
    olddir /srv/scaled/var/log/old/ 
}
    • su magemojo magemojo — Ensures that permissions stay correct
    • daily – Run once a day at time set by cron job
    • missingok — Don't panic if empty
    • rotate 30 — Retain for 30 days
    • compress — Compress 2nd most recent file
    • delaycompress — Do not compress newest rotated log
    • notifempty — Do not rotate empty files

  3. Add a cron job to run once a day at the correct time:

    /usr/sbin/logrotate -s /srv/etc/logrotate/logrotate.state /srv/etc/logrotate/logrotate.conf
