解压到D:\mysql-5.7.12-winx64

设置set path=%path%;D:\mysql-5.7.12-winx64\bin;

新建my.ini 复制my-defualt.ini内容

加入：

basedir=D:\mysql-5.7.12-winx64

datadir=D:\mysql-5.7.12-winx64\data

port = 3306

管理员权限进入D:\mysql-5.7.12-winx64\bin

mysqld --initialize --user=mysql --console

此处会生成一个随机密码

mysql -uroot -p

A temporary password is generated for root@localhost: ?ed&Dd9j#r1O

安装mysql服务，默认名为mysql

mysqld -install [server name]

启动mysql

net start mysql

登陆

mysql -u[user] -p [password]

mysql -uroot -p ?ed&Dd9j#r1O

修改密码

首先停止服务net stop mysql

mysqld --skip-grant-tables

另起一个admin cmd窗口,在bin目录下执行

mysql -uroot -p

show databases;

use mysql;

update mysql.user set authentication_string=password('new_password') where user='root' and Host = 'localhost';

flush privileges;

quit;

mysql -uroot -p 登录

[ERROR]You must reset your password using ALTER USER statement before executing this statement.

set password =password('new password');

alter user 'root'@'localhost' password expire never;

flush privileges;

exit;

重新登录
