                Install MySQL 5.7 on macOS using Homebrew
              
          
This is a fork of original gist https://gist.github.com/nrollr/3f57fc15ded7dddddcc4e82fe137b58e, with slight changes on pointing to 5.7 version branch, instead of 8 (latest default of MySQL in Hombrew).

Install MySQL 5.7 on macOS

This procedure explains how to install MySQL using Homebrew on macOS (Sierra 10.12 and up)
Install Homebrew


Installing Homebrew is effortless, open Terminal and enter :

$  /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Note: Homebrew will download and install Command Line Tools for Xcode 8.0 as part of the installation process.
