mysql安装（Mac平台）

mac平台安装mysql有两种方式：

1）使用官方度dmg安装；

2）使用homebrew方式

本人比较推荐使用homebrew方式安装，省去大多数的麻烦，使用官方dmg方式推荐到官网下载：http://dev.mysql.com/downloads/mysql/

使用homebrew方式

安装：

sudo brew install mysql

启动：

sudo mysql.server start

有可能会遇到下面这个问题：

Starting MySQL
.. ERROR! The server quit without updating PID file (/usr/local/var/mysql/Joshs-MacBook-Pro.local.pid).

其实就是改下文件权限：

adeMacBook-Pro:~ apple$ sudo chown -R mysql /usr/local/var/mysql/

adeMacBook-Pro:~ apple$ sudo mysql.server start

Starting MySQL

. SUCCESS!
