MYSQL教程修改保存后,在cmd中,由于我们已经在path配置了环境变量,所以我们可以直接启动mysql

MYSQL教程
net start mysql 

MYSQL教程启动成功后,登录mysql

MYSQL教程
mysql -u root -p 

MYSQL教程密码为空 这里我们直接回车登录成功
登录成功后,我们修改数据库执行如下

MYSQL教程
use mysql

MYSQL教程
update user set authentication_string=password("123456") where user="root"; 

MYSQL教程这里注意最后必需加上分号

MYSQL教程成功后刷新

MYSQL教程
flush privileges; 

MYSQL教程致此我们密码就修改成功了,退出关闭mysql服务,然后把my.ini中最后一行注释掉,从新启动mysql服务,发现新密码生效.
