====== Log Rotate ======

**General Information**

  * Logrotate is executed via a daily cron job: /etc/cron.daily/logrotate

**Checklist**
  * Distro(s): Enterprise Linux 6

----

===== Force Rotation =====

Forcing a log rotation can be useful after implementing a new rotation file (in /etc/logrotate.d) or to test after making changes.

  * To force a logrotate using a specific config file
    * <code bash>/usr/sbin/logrotate -f /etc/logrotate.d/myapp</code>
  * To force a logrotate of ALL log files
    * <code bash>/usr/sbin/logrotate -f /etc/logrotate.conf</code>

----

===== /etc/logrotate.conf =====

/etc/logrotate.conf is left alone in its default installed state.

Ensure that /etc/logrotate.d is included (it is by default):
<code bash>
include /etc/logrotate.d
</code>

----

===== /etc/logrotate.d/ =====

All additional log configuration files go in: /etc/logrotate.d/

Example Log Config
<code bash>
## Application Logs ##
/opt/myapp/logs/logs.txt {
  #Rotate monthly
  monthly
  
  #Keep 12 old log files, delete older
  rotate 12
  
  #Copy current log to rotated, then truncate in place
  copytruncate
  
  #Give rotated log file a date extension YYYYMMDD
  dateext
  
  #Compress old log files with gzip
  compress
}
</code>
