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.

Install MySQL

At this time of writing, Homebrew has MySQL version 8 as default, but as we're aiming to get 5.7, we'll need to append @5.7 to the default package key:

• Enter the following command : $ brew info mysql@5.7
• Expected output: mysql@5.7: stable 5.7.22 (bottled) [keg-only]

To install MySQL enter : $ brew install mysql@5.7

Additional configuration

Homebrew

• Install brew services first : $ brew tap homebrew/services

• Load and start the MySQL service : $ brew services start mysql@5.7.
  Expected output : Successfully started mysql (label: homebrew.mxcl.mysql)

• Check of the MySQL service has been loaded : $ brew services list 1

• Force link 5.7 version - $ brew link mysql@5.7 --force

• Verify the installed MySQL instance : $ mysql -V.
  Expected output : Ver 14.14 Distrib 5.7.22, for osx10.13 (x86_64)

MySQL

Open Terminal and execute the following command to set the root password:
mysqladmin -u root password 'yourpassword'

Important : Use the single ‘quotes’ to surround the password and make sure to select a strong password!

Database Management

To manage your databases, I recommend using Sequel Pro, a MySQL management tool designed for macOS.
Current version available: 1.1.2

Comments

1 The brew services start mysql@5.7 - instruction is equal to :

$ ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
