    Set up databases to run AS YOUR USER ACCOUNT with:
        unset TMPDIR
        mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=#{var}/mysql --tmpdir=/tmp

    To set up base tables in another folder, or use a different user to run
    mysqld, view the help for mysql_install_db:
        mysql_install_db --help

    and view the MySQL documentation:
      * http://dev.mysql.com/doc/refman/5.6/en/mysql-install-db.html
      * http://dev.mysql.com/doc/refman/5.6/en/default-privileges.html

    To run as, for instance, user "mysql", you may need to `sudo`:
        sudo mysql_install_db ...options...

    A "/etc/my.cnf" from another install may interfere with a Homebrew-built
    server starting up correctly.

    To connect:
        mysql -uroot
