Access denied for user ‘root‘@‘localhost‘ (using password:YES)解决方法

分手后的思念是犯贱 2024-04-01 14:37 80阅读 0赞

之所以想解决并记录这个问题，不是因为 Navicat 中的链接双击打开一直报错（内容如标题），而是在IDEA打算链接数据库的时候，报了同样的错误。

百度，csdn每篇文章都写着：你密码错了，尽管我分明已经在建立之初就把密码登记在小本本上，我对自己十分自信，但“报错”显然对我没什么自信。

按照这篇浏览2千却比某些浏览2w+的文章内容要好得多的文章：[(101条消息) Access denied for user 'root'@'localhost' (using password:YES)解决方法\_weixin\_30342209的博客-CSDN博客][101_ Access denied for user _root_localhost_ _using password_YES_weixin_30342209_-CSDN]

第1步：管理员的身份运行cmd

第2步：

C:\WINDOWS\system32>net stop mysql

第3步：自行切换到你自己的mysql\\bin

第4步：

D:\download_3\Mysql_1\mysql\bin>mysqld  --defaults-file="D:\download_3\Mysql_1\mysql\my.ini" --console --skip-grant-tables

第5步：开另外一个cmd，管理员的身份运行

\bin>mysql -uroot mysql

打脸了，又找了一篇文章解决上面这个报错，结果是让我启动mysql，”又回到最初的起点~“

当然重新找到的文章2写的很好，不过不是对应我这个问题的

又又找到一篇大佬文章，也是按上面新出现的问题去找（套娃开始！），先启动Mysql，然后试着登录，输入我记本本上的密码，好极了————————————————

bin>mysql -u root -p

报错。

由于文章3是大佬作（很明显），于是我决定重来，跟着操作一遍。

前3步和上面的一模一样，第4步，关键来了，大佬指出，Mysql 8.0是用不了上面的方法来跳过密码登录，而是输入：

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

我\*，我第一次感觉我找对文章了，这文章不仅有码，还有效果截图，他真的，我哭死

开第二个cmd，管理员的身份运行

出现不一致，应该是版本不一样的原因：

先走了再说

下图将界面显示与代码结合了：

    //Database changed
    mysql> update user set authentication_string='' where user='root';
    //Query OK, 1 row affected (0.04 sec)

省流：将Mysql密码改为root。
