What creates MySQL's DB Schema Tables?

I have twice attempted to install the /usr/ports/databases/mysql57-server with make install. All seems to progress as advertised; however, the db schema tables are not created in /var/db/mysql/. What am I missing here? I expected the complement of tables to be created, but no. So . . .what creates them? Is there a shell script hidden somewhere that needs to be run? (Never had this problem before. Running FreeBSD 10.2-RELEASE. Can't search this forum, Google search, ad nauseam to find an answer.)
 
. . .ok . . .on a whim, I decided to try service mysql-server start and voilà, there are these files. Like my late friend, Pat Henry used to say, "This is going to make perfect sense . . .once I understand it."

So, apparently, simply starting the service automagically created the support files, and the db schema tables in /var/db/mysql/mysql. Geez . . .let's see . . .what can we do to make this more obtuse ;)

If you read the start script /usr/local/etc/rc.d/mysql-server you can see exactly what's happening:
Code: 
        if [ ! -d "${mysql_dbdir}/mysql/." ]; then
                mysql_create_auth_tables || return 1
        fi
Code: 
mysql_install_db="/usr/local/bin/mysql_install_db"
mysql_install_db_args="--basedir=/usr/local --datadir=${mysql_dbdir} --force"

mysql_create_auth_tables()
{
        eval $mysql_install_db $mysql_install_db_args
        [ $? -eq 0 ] && chown -R ${mysql_user}:$(id -gn $mysql_user) ${mysql_dbdir}
}
 
This is probably my fifth or sixth install of MySQL. Over the years, I don't recall this nuance being embedded in the start-up script. Perhaps I'm just old and forgetful; regardless, clarification in the documentation would be helpful, rather than having to discover it by analysis of the startup script. Frankly, at first (and second and third ...) I didn't attempt to start the mysql-server because after the install completed, I could not find the database, and I expected the server to fail to start because the database was missing. (I'm and old-school programmer, and I look for these things first.)
 
For as long as I can remember the MySQL start scripts have always automatically created the initial databases when you first start it. Perhaps you never realized it?
 
You're probably right. In the past, I probably just "started" the server following a successful install and never realized that the first-time startup installed the database tables. Because of some other related problems, I looked for the database schema before attempting a startup and became alarmed that they were not installed.

Anyway, have a :beer: on me (send me the tab.)
