Mac Pro 下MySql的安装及配置使用

一、安装：

https://dev.mysql.com/doc/refman/5.6/en/osx-installation-pkg.html 到这个网址下载，下载之后点击安装（傻瓜式安装），
为什么我要写这篇博客记录下来呢？重点不是它的安装，而是我遇到了一些问题，

二、配置

打开终端
打开配置
输入：.bash_profile

输入：export PATH=${PATH}:/usr/local/mysql/bin 保存

然后，在系统偏好设置中打开MySql ，在终端进行登录的时候会出现

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) 

解决这个问题的办法
1、打开终端输入/usr/local/mysql/bin/mysqld_safe –skip-grant-tables

出现上边的结果，然后不要关闭当前的终端，重新打开一个 ，
2、输入/usr/local/mysql/bin/mysql 会展示出

mysql> 

3、打开use mysql;
结果：

Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

4、然后更改root的密码

mysql> update user set authentication_string=password('root') where Host='localhost' and User='root';

5、退出保存，重新启动服务 搞定
