windows安装mysql8

A temporary password is generated for root@localhost: upkiQXrdO8+l

mysql8zip安装教程：
1：下载mysql-8.0.23-winx64 并且解压缩
2： 配置环境变量,比如：

D:\mysql\mysql-8.0.23-winx64\bin,这样在任何地方都能调用mysqld服务
3: 在mysql-8.0.23-winx64 解压后文件夹中新建my.ini [和bin目录同级]

4：my.ini内容如下：

[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=C:\Program Files\mysql
# 设置mysql数据库的数据的存放目录
datadir=C:\Program Files\mysql\Data
# 允许最大连接数
max_connections=200
# 允许连接失败的次数。
max_connect_errors=10
# 服务端使用的字符集默认为utf8mb4
character-set-server=utf8mb4
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 默认使用“mysql_native_password”插件认证
#mysql_native_password
default_authentication_plugin=mysql_native_password
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8mb4
[client]
# 设置mysql客户端连接服务端时默认使用的端口
port=3306
default-character-set=utf8mb4

5：用管理员权限打开cmd: 执行：mysqld --initialize --console 初始化mysql
