Daily Shell Commands

# Rotate logs
1) vim or nano /etc/logrotate.conf
2) Add these lines to the bottom of the file
/home/deploy/APPNAME/current/log/*.log {
  daily
  missingok
  rotate 7
  compress
  delaycompress
  notifempty
  copytruncate
}

You’ll need to change the first line to match the location where your Rails app is deployed
3) run logrotate manually `sudo /usr/sbin/logrotate -f /etc/logrotate.conf`
4) run the above command again to make sure the delaycompress option is working and to actually compress the log.
