Log file rotation script

[Corey Donohoe]

We use logrotate and things work just fine.

/var/log/engineyard/nginx/*.log {
  daily
  missingok
  compress
  rotate 30
  dateext
  notifempty
  sharedscripts
  extension gz
  postrotate
    [ ! -f /var/run/nginx.pid ] || kill -USR1 `cat /var/run/nginx.pid`
  endscript
}
