忘记密码了怎么重置密码

如果你不小心忘记root密码 重置方法如下

首先停止mysql 。然后使用参数–skip-grant-tables --shared-memory手动启动mysql。

mysqld  --console  --skip-grant-tables --shared-memory

此时新创建客户端窗口连接root账户就不用输入密码 直接进入mysql命令行了。进入后就能执行修改密码的命令

mysql -uroot
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';

修改完成后 停止mysql。在用正常启动的方式重启mysql数据即可。密码就被强制找回。
