#All of the files for the sites that you host will be located in directories that exist underneath /srv/www. You can symbolically link these directories to other locations if you need them to exist in other places.
#ErrorLog and CustomLog entries are suggested for more fine-grained logging, but are not required. If they are defined (as shown above), the logs directories must be created before you restart Apache.

mkdir /srv/www/otrs.local/logs
