brew install mysql on mac os el capitan

Question

I'm trying to install mysql on MAC OS version 10.11.2 by following the methods in this link,

The following command has been successfully executed,

brew install mysql

but when I type the following command,

mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

I get the following error:

mysql_install_db: [ERROR] unknown variable 'tmpdir=/tmp'

Please help. Thanks in advance.
