mysql重置密码
1.命令行进入安装mysql的bin目录下;
2.执行mysqld --skip-grant-tables命令跳过登录验证;
3.执行msyql命令无需密码登录;
4.执行show databases;命令查询所有数据库;
5.使用名称为“mysql”的数据库(use mysql;);
6.执行show tables;sql语句查询“mysql”数据库下的所有表;
7.执行select user,host,authentication_string from user;查询用户名和密码;
8.执行update user set password=password('你的密码') where user='root' and host='localhost';语句更改root密码;
以上方法改密码会出现结束mysql进程后,第二次再进行登录会报错(权限问题),解决方法如下:
1.执行net start mysql 开启mysql数据库服务;
2.执行alter user 'root'@'localhost' identified by '自己的密码'; 修改密码;
3.执行flush privileges;命令刷新权限;
4.执行help contents命令查询修改信息;
5.弹出信息如下,则成功:
