Mac下安裝MySQL簡單到想哭，基本上就是brew搜索一下，安裝，啟動，即可。
$ brew install mysql
$ mysql.server start
如果想停止，可以使用：
$ mysql.server stop
以下是我的機器上，brew search/info的輸出，尤其是最后的啟動命令，很有用。
bash-3.2$ brew search mysql
automysqlbackup mysql-cluster mysql-sandbox mysql@5.5
mysql ? mysql-connector-c mysql-search-replace mysql@5.6
mysql++ mysql-connector-c++ mysql-utilities mysqltuner
caskroom/cask/mysql-connector-python caskroom/cask/sqlpro-for-mysql caskroom/cask/navicat-for-mysql
caskroom/cask/mysql-utilities caskroom/cask/mysql-shell
bash-3.2$ brew info mysql
mysql: stable 5.7.19 (bottled)

Conflicts with:
mariadb (because mysql, mariadb, and percona install the same binaries.)
mariadb-connector-c (because both install plugins)
mysql-cluster (because mysql, mariadb, and percona install the same binaries.)
mysql-connector-c (because both install MySQL client libraries)

==> Caveats
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
MySQL is configured to only allow connections from localhost by default
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
