windows平台mysql密码破解设置
windows平台下,5.7版本mysql,破解密码的两种方式:
#1 关闭mysql服务
net stop mysql
启动mysql服务 跳过权限
#2 在cmd中执行:mysqld --skip-grant-tables
另开一个cmd
#3 在cmd中执行:mysql
之前账号有密码的 不输入密码 可以进去
C:\Users\Administrator.QH-20170325TNQR>mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.6.41 MySQL Community Server (GPL) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql> select user; ERROR 1054 (42S22): Unknown column 'user' in 'field list' mysql> select user(); +--------+ | user() | +--------+ | root@ | +--------+ 1 row in set (0.00 sec)
#4 执行如下sql:
更改之前mysql 密码
设置mysql库.user数据表 set设置密码 改为空
update mysql.user set authentication_string=password('') where user = 'root';
另外一种sql语句实现
update mysql.user set password=password("") where user="root" and host="l ocalhost";
执行完sql语句 执行这条语句让sql语句生效
刷新数据表 刷新权限
flush privileges;
把刚才mysql服务进程 kill掉
#5 tskill mysqld #或taskkill -f /PID 7832
查看mysqld 进程
C:\Users\Administrator.QH-20170325TNQR>tasklist |findstr mysqld mysqld.exe 7456 Console 1 456,020 K
kill 进程
C:\Users\Administrator.QH-20170325TNQR>taskkill -f /PID 7456 成功: 已终止 PID 为 7456 的进程。
#6 重新启动mysql
net start mysql
方式二
#1. 关闭mysql,可以用tskill mysqld将其杀死
#2. 在解压目录下,新建mysql配置文件my.ini
#3. my.ini内容,指定
[mysqld]
skip-grant-tables
#4.启动mysqld
#5.在cmd里直接输入mysql登录,然后操作
update mysql.user set authentication_string=password('') where user='root and host='localhost';
flush privileges;
#6.注释my.ini中的skip-grant-tables,然后启动myqsld,然后就可以以新密码登录了
