　　我之前介绍过window环境下安装mysql服务，以及在Linux环境下安装mysql服务，今天我要给大家介绍的是在Mac环境下安装mysql服务。其实安装mysql服务我们也可以像Linux那样，使用brew命令进行安装，但我们此处使用的是绿色方式安装。

 

 

一.下载mysql服务

1>.登录mysql的下载列表

　　下载地址：https://dev.mysql.com/downloads/mysql/。如下图所示，点击标红的标签。

 2>.下载DMG版本的mysql安装包

 

3>.跳过登录直接下载mysql服务即可

二.安装mysql服务

1>.双击运行下载好的安装包，点击继续

2>.阅读软件许可协议后，点击继续

 

3>.点击安装

 

4>.记住安装的数据库的初始密码（如下图所示，我这里的初始化密码是：M7Rju)ofMFMb）

 

5>.安装成功

 

三.启动mysql服务

1>.进入mysql的系统偏好设置

2>.点击mysql服务

 

3>.启动mysql服务

 

4>. 服务启动成功

 

 

四.修改mysql的默认密码 

1>.登录mysql服务器

2>.更改mysql的默认密码

set password for 'root'@'localhost' = PASSWORD('yinzhengjie');

3>.使用修改后的密码登录服务器 

五>.授权mysql远程主机登录

1>.授权只运行的主机

2>.查看宿主机的IP地址

 

3>.使用Guest虚拟机登录宿主机 

六.安装MySQL8.0.x的区别

1>.MySQL加密方式的选择（之前的安装步骤和上面MySQL5.7的安装方式基本雷同，我这里就省略了～）

2>.自定义root的密码：

3>.安装成功后，点击完成

4>.在MacOS到系统偏好设置进入到MySQL到管理界面

5>.查看MySQL的默认配置

 

6>.登陆MySQL服务器 

7>.将MySQL的安装路径手动添加到环境变量中
