本文介绍了在 WAMP 上重新获得对 PHPMyAdmin 丢失的 MySQL 密码的访问权限的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我在 PHPMyAdmin 中更改了我的 'root'@'localhost' 帐户的密码(这个人在这里问) 并在我的浏览器上将自己锁定在 PHPMyAdmin 之外.我使用的是 WAMP 2.5.

I changed the password for my 'root'@'localhost' account in PHPMyAdmin and like (this person asking here) and locked myself out of PHPMyAdmin on my browser. I am using WAMP 2.5.

针对该问题提供的解决方案对我不起作用,因为不幸的是我丢失了将 root 重新分配给的密码.

The solutions offered on that question don’t work for me because unfortunately I have lost the password that I reassigned root to.

有些解决方案要求通过命令行重置密码(包括这个源),我已经通过 Windows 命令行尝试过但没有成功,因为我现在没有权限:

Some solutions ask one to reset the password via command line (including this source), and I have tried that through the Windows command line without success because I now have no privileges:

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('mynewpassword');

ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'mysql'

WAMP 带有 MySQL 控制台,但我无法使用它,因为它提示我输入密码,正如我所说,该密码不再存在.

WAMP comes with a MySQL Console but I am unable to use it since it prompts me for a password which as I stated, no longer have.

此视频说明了如何更改密码,与StackExchange 上面的回答,但显然,我现在需要另一种方法来做到这一点,因为我不知道我会像那个人警告的那样失去访问权限.

This video explains how to change passwords, and it agrees with the answers in the StackExchange answer above, but evidently, I need another method to do this now since I did not know I would lose access as the guy warns.

如果这是新手要问的问题,我将不胜感激,并表示歉意.我刚刚掌握了使用堆栈进行 Web 开发的窍门,并且通过 WAMP 配置对 LAN 站点的访问是一次冒险,所以如果可能的话,我更喜欢不需要重新安装所有东西的东西.

I would appreciate any advice and apologise if this is a newbie type of thing to ask. I am just getting the hang of using a stack for web development, and configuring access to a LAN site through WAMP was quite an adventure, so if possible, I would prefer something that does not require reinstalling everything again.

编辑 1:继续尝试@RiggsFolly 的解决方案.虽然我可以访问 my.ini 文件,毫无问题地进行更改,并通过 WAMP 或其他方式毫无问题地重新启动 MySQL,但行 skip-grant-tables 未生效,给我留下密码提示或无法执行任何操作.(我在这里写了一个新问题来解决这个问题,因为我觉得这是一个不同的问题.)

Edit 1: Went ahead and tried @RiggsFolly ’s solution. While I can access the my.ini file, make changes without problem, and restart MySQL without issue through WAMP or otherwise, the line skip-grant-tables is not taking effect, leaving me with a password prompt or no access to do anything. (I wrote a new question here to troubleshoot this since I feel like this is a different issue.)

Edit 2:我尝试了@t.niese 在评论中提供的链接中的说明,当我将控制台设置为返回对说明的反馈时,它报告了这一点,并且无法更改任何东西:

Edit 2: I tried the instructions in the link provided by @t.niese in the comments and when I set the console to return feedback on the instructions, it reported this, and failed to change anything:

C:\wamp\bin\mysql\mysql5.6.17\bin>mysqld --skip-grant-tables --console

推荐答案

这里有一种方法可以让您非常简单地重置 MYSQL 'root' 密码.

Here is a method that will allow you to reset the MYSQL 'root' password quite simply.

停止mysql服务

wampmanager -> MySQL -> Service -> Stop Service

编辑 my.ini 文件

Edit the my.ini file

wampmanager -> MySQL -> my.ini

在ini文件中找到[wampmysqld](32bit)或[wampmysqld64](64bit)部分

Find the [wampmysqld](32bit) or [wampmysqld64](64bit) section in the ini file

在该部分标题后直接添加此行

Add this line directly after that section heading

skip-grant-tables

重启mysql服务.

wampmanager -> MySQL -> Service -> Start/Resume Service

打开 MySQL 控制台

Open the MySQL console

wampmanager -> MySQL -> MySQL Console

现在我们要重置root用户的密码,当然这可以用来重置任何用户的密码.

Now we are going to reset the password for the root user, of course this could be used to reset any users password.

mysql>命令提示符下输入以下2条命令,每行最后一个分号,每行后按ENTER向mysql发出命令.

Enter the following 2 commands at the mysql> command prompt, each with a semi colon at the end of a line, and press ENTER after each line to issue the command to mysql.

MYSQL 5.7 之前的版本

UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
FLUSH PRIVILEGES;

发布 MYSQL 5.7 版后列名发生了变化

UPDATE mysql.user SET authentication_string=PASSWORD('MyNewPass') WHERE User='root';
FLUSH PRIVILEGES;

请注意,更新可能会报告它更新了不止一行,因为可能有多个用户帐户的用户 ID 为root",每个帐户都具有不同的域,即 127.0.0.1、localhost 和::1

现在在 mysql 命令提示符处输入 'quit' 以存在 mysql.

Now enter 'quit' at the mysql command promt to exist mysql.

停止mysql服务

wampmanager -> MySQL -> Service -> Stop Service

编辑 my.ini 文件

Edit the my.ini file

wampmanager -> MySQL -> my.ini

在ini文件中找到[wampmysqld](32bit)或[wampmysqld64](64bit)部分

Find the [wampmysqld](32bit) or [wampmysqld64](64bit) section in the ini file

删除我们之前添加的 skip-grant-tables 参数.

Remove the skip-grant-tables parameter we added earlier.

不要将此参数留在ini文件中,这是一个巨大的安全漏洞.

重启mysql服务.

wampmanager -> MySQL -> Service -> Start/Resume Service

现在,如果您愿意,您可以设置 root 用户帐户,使其不会自动使密码过期

Now if you want you can set the root user account so it does not expire the password automatically

wampmanager -> MySQL -> MySQL Console

然后运行这个查询

ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;

您现在应该可以使用用户 ID 'root' 和您刚刚为该用户设置的新密码通过 phpmyadmin 登录.

You should now be able to login with phpmyadmin using the userid 'root' and the new password you have just set for that user.
