Win10系统MySQL5.7密码忘记怎么重置?

在Win10系统下安装了MysqL使用，有时遇到密码忘记的问题也是挺遭心的，那么如何重置MysqL密码呢？下面小编就分享下具体教程。

Win10下MysqL密码重置步骤如下：

1、首先点击开始菜单，搜索cmd.exe，左击以管理员身份运行

操作之前先备份好数据库（切忌）

C:UsersAdministrator>cd C:Program FilesMysqLMysqL Server 5.7bin

C:Program FilesMysqLMysqL Server 5.7bin>MysqLd --skip-grants-tables

//发现不成功，原因是没有data目录，于是在此C:Program FilesMysqLMysqL Server 5.7目录下创建了data目录，成功执行且可以跳过认证

//但是进入数据库发现原来的库都不见了，原来是默认情况下，MysqL的数据库文件是保存在C:/ProgramData/MysqL/MysqL Server 5.7/Data/ 而且，Win7，Win10缺省是把C:/ProgramData目录隐藏的。

//因此我们需要指定配置文件来启动

C:Program FilesMysqLMysqL Server 5.7bin>MysqLd --defaults-file=C:ProgramDataMysqLMysqL Server 5.7my.ini --user=MysqL --skip-grants-tables

//进入数据库

C:Program FilesMysqLMysqL Server 5.7bin>MysqL

MysqL> flush privileges; #更新权限

//退出再使用新密码登陆,上面的红色密码 root 等改成自己的用户名和密码

方法二：

MysqL > set password for root@localhost = password('MysqLroot');

方法三：

MysqLadmin -u UserName -h Host password 'new_password' -p
