安裝網上很多，選擇教程：windows下MySQLCommunity Server 5.7.24 安裝方法
教程有些小問題，
1.my.ini在bin目錄下是沒有，直接複製下面代碼即可：
[mysql]
# 設置mysql客戶端默認字符集
default-character-set=utf8
[mysqld]
#設置3306端口
port = 3306
# 設置mysql的安裝目錄
basedir=D:\mysql-5.7.24-winx64
# 設置mysql數據庫的數據的存放目錄
datadir=D:\mysql-5.7.24-winx64\data
# 允許最大連接數
max_connections=200
# 服務端使用的字符集默認爲8比特編碼的latin1字符集
character-set-server=utf8
# 創建新表時將使用的默認存儲引擎
default-storage-engine=INNODB 2.臨時密碼位置，不太好找，需要仔細看英文： joepvsEcu6&(這個是臨時密碼
