Damit die Logdateien nicht zu groß werden, sollten Sie Logrotate anweisen die Logdateien regelmäßig zu archivieren und nach einer gewissen Zeit zu löschen. Dazu erstellen Sie einfach die Datei /etc/logrotate.d/centos5_mirror.

[root@centos5 ~]# vi /etc/logrotate.d/centos5_mirror

Fügen Sie in diese Datei die folgenden Zeilen ein. Dadurch wird die Logdatei /var/log/centos5_mirror.log monatlich und die Logdatei /var/log/centos5_mirror.debug wöchentlich archiviert. Von beiden Logdateien werden nur die letzten drei Archivdateien vorgehalten. Ältere Archive werden automatisch gelöscht.

/var/log/centos5_mirror.log {
    monthly
    rotate 3
    compress
    delaycompress
    missingok
    notifempty
}

/var/log/centos5_mirror.debug {
    weekly
    rotate 3
    compress
    delaycompress
    missingok
    notifempty
}
