Log rotation and combining...

[Bill Shirley]

I believe you need a 'create' statement to set the permissions. Here
is an example for mariadb:
/var/log/mariadb/general.log
/var/log/mariadb/slow_query.log
/var/log/mariadb/error.log
/var/log/mariadb/mariadb.log {
         create 640 mysql mysql
         daily
         minsize 30M
         notifempty
         rotate 3
         missingok
         compress
         sharedscripts
         postrotate
#       # just if mysqld is really running
                 if test -x /usr/bin/mysqladmin && \
                         /usr/bin/mysqladmin ping &>/dev/null
                 then
                         /usr/bin/mysqladmin flush-logs
                 fi
         endscript
}
