mac 上安装 mysql

1.点击dmg文件安装，一路点next即可，中间需要什么权限都给，记得保存过程中生成的临时密码：我的如下

2016-05-20T12:33:12.204930Z 1 [Note] A temporary password is generated for root@localhost: _#aPNpyT8H.)

If you lose this password, please consult the section How to Reset the Root Password in the MySQL reference manual.

2.配置Mac的mysql环境变量：

 1⃣️.打开终端,输入： cd ~

会进入~文件夹

 2⃣️然后输入：touch .bash_profile

回车执行后，

 3⃣️.再输入：open -e .bash_profile

会在TextEdit中打开这个文件（如果以前没有配置过环境变量，那么这应该是一个空白文档）。如果有内容，请在结束符前输入，如果没有内容，请直接输入如下语句：

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

然后，保存，退出

3.打开终端：依次如下：

输入：mysql -u root -p

输入零时密码：_#aPNpyT8H.)

 显示：
