下载mysql地址
下载了 MySQL Community Server 5.7.24
并开始安装：
安装网上很多，选择教程：windows下MySQLCommunity Server 5.7.24 安装方法
教程有些小问题，
1.my.ini在bin目录下是没有，直接复制下面代码即可：
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
#设置3306端口
port = 3306
# 设置mysql的安装目录
basedir=D:\mysql-5.7.24-winx64
# 设置mysql数据库的数据的存放目录
datadir=D:\mysql-5.7.24-winx64\data
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB 2.临时密码位置，不太好找，需要仔细看英文： joepvsEcu6&(这个是临时密码
