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
