By default MySQL daemon run as user "mysql". If you want start/stop
mysqld then in /usr/local/etc/rc.d /mysql-server.sh replace line
mysql_user="mysql" to mysql_user="<your-account>"
and change in /etc/rc.conf mysql_dbdir="/xxx/xxx/xx" or chahge owner
for /xxx/xxx/xx to <your-account>
Needed directory structure will created.
Before all changes stop mysqld.
