我之前介紹過window環境下安裝mysql服務，以及在Linux環境下安裝mysql服務，今天我要給大家介紹的是在Mac環境下安裝mysql服務。其實安裝mysql服務我們也可以像Linux那樣，使用brew命令進行安裝，但我們此處使用的是綠色方式安裝。
一.下載mysql服務
1>.登錄mysql的下載列表
下載地址：https://dev.mysql.com/downloads/mysql/。如下圖所示，點擊標紅的標簽。
2>.下載DMG版本的mysql安裝包
3>.跳過登錄直接下載mysql服務即可
二.安裝mysql服務
1>.雙擊運行下載好的安裝包，點擊繼續
2>.閱讀軟件許可協議后，點擊繼續
3>.點擊安裝
4>.記住安裝的數據庫的初始密碼（如下圖所示，我這里的初始化密碼是：M7Rju)ofMFMb）
5>.安裝成功
三.啟動mysql服務
1>.進入mysql的系統偏好設置
2>.點擊mysql服務
3>.啟動mysql服務
4>. 服務啟動成功
四.修改mysql的默認密碼
1>.登錄mysql服務器
2>.更改mysql的默認密碼
set password for 'root'@'localhost' = PASSWORD('yinzhengjie');
3>.使用修改后的密碼登錄服務器
五>.授權mysql遠程主機登錄
1>.授權只運行的主機

2>.查看宿主機的IP地址
3>.使用Guest虛擬機登錄宿主機
六.安裝MySQL8.0.x的區別
1>.MySQL加密方式的選擇（之前的安裝步驟和上面MySQL5.7的安裝方式基本雷同，我這里就省略了～）
2>.自定義root的密碼：
3>.安裝成功后，點擊完成
4>.在MacOS到系統偏好設置進入到MySQL到管理界面
5>.查看MySQL的默認配置
6>.登陸MySQL服務器
7>.將MySQL的安裝路徑手動添加到環境變量中
