1. 执行：

$ brew install mysql

2. 在 /usr/local/etc/ 下创建或修改 my.cnf，示例：

[client]
port = 3306
socket = /tmp/mysql.sock
default-character-set = utf8

[mysqld]
collation-server = utf8_unicode_ci
character-set-server = utf8
init-connect ='SET NAMES utf8'
max_allowed_packet = 64M
bind-address = 127.0.0.1
port = 3306
socket = /tmp/mysql.sock
innodb_file_per_table=1

[mysqld_safe]
timezone = '+0:00'

3. 然后就可以指向 mysql.server start 来启动了
