Mac に MySQL を Homebrew でインストールしたので、その手順をご紹介します。（最終更新日：2017/03/25）
事前準備 Homebrew インストール
Homebrew のインストールがまだの方はこちらの記事をご参考にして下さい。
MySQL のインストール
brew install mysql
==> Downloading https://homebrew.bintray.com/bottles/mysql-5.7.17.el_capitan.bottle.1.tar.gz
######################################################################## 100.0%
==> Pouring mysql-5.7.17.el_capitan.bottle.1.tar.gz
==> Using the sandbox
==> /usr/local/Cellar/mysql/5.7.17/bin/mysqld --initialize-insecure --user=your_username --basedir=/usr/local/Cellar/mysql/5.7.17 --datadir=/usr/local/var/mysql --t
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
To connect run:
mysql -uroot
To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start
==> Summary
/usr/local/Cellar/mysql/5.7.17: 321 files, 234.4MB
MySQL 自動起動設定
brew services start mysql
==> Successfully started `mysql` (label: homebrew.mxcl.mysql)
MySQL 手動起動コマンド
mysql.server start
