MySQL 安装和上手使用 on Mac

安装

之前看 MySQL 的入门教程的时候发现不是很容易找到和自己环境完全一样的方法，后来问同事，作比较终于走通了。安装方法不只是一种，用的相关 APP 也不是一种，每种都是可行的，但是这里只描述自己更偏好的那一种 :D。这篇文章假设读者开始对 MySQL 都没有一个概念，所以除了软件的安装和配置，还会简单介绍一点点关于 MySQL 的东西。

首先 $ brew install mysql 安装 mysql，之后可能需要重启一下终端，然后成功的话输入 $ mysql 再按 Tab 会提示一些和 mysql 相关的命令出来，如果有的话就 OK 了，如下：

$ mysql
