配置文件my.ini

[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=E:\database\MySQL\Data

允许最大连接数

max_connections=200

允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统

max_connect_errors=10

服务端使用的字符集默认为UTF8

character-set-server=utf8

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

default_authentication_plugin=mysql_native_password
[mysql]

设置mysql客户端默认字符集

default-character-set=utf8
[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=utf8

初始化数据库
mysqld –initialize –console

注意！执行输出结果里面有一段： [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: rI5rvf5x5G,E 其中root@localhost:后面的“rI5rvf5x5G,E”就是初始密码（不含首位空格）。在没有更改密码前，需要记住这个密码，后续登录需要用到。

安装服务
mysqld –install

net start mysql

mysql -uroot -p;sHD)Yjrd9kr

ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘root’;

show database;
