Question

我无法访问MySQL v.5.6.14.我有权进入,突然间我失去了它.

寻找笔记我发现下面的网址.我做了一些步骤,但没有成功. http://dev.mysql.com/doc/refman/5.5/en/resetting-permissions.html

C:\ Program Files\MySQL\bin> mysqld

2013-11-14 19:46:01 0 [警告]不推荐使用具有隐式DEFAULT值的TIMESTAMP.请使用--explicit_defaults_for_timestamp服务器选项(有关详细信息,请参阅文档)

C:\ Program Files\MySQL\bin> mysql -u root mysql1

ERROR 1045(28000):用户'root'@'localhost'拒绝访问(使用密码:否)

注意:我没有mysqld_safe或safe_mysqld在MySQL版本的文件

请你帮助我好吗？您可以在下面看到该命令生成的转储文件:

C:\mysqld --init-file=C:\\mysql-init.txt

---

C:\Program Files\MySQL\bin>mysqld --init-file=C:\\mysql-init.txt --console

Answer 1

我有同样的问题.mysql -u root -p为我工作.它稍后会要求您输入密码.然后,您应该输入为mysql设置的密码.password如果您没有设置密码,则默认密码可以是.更多信息在这里.

Answer 2

请按照以下步骤操作:

1. 完全停止MySQL服务器.这可以通过访问Windows XP和Windows Server 2003中的"服务"窗口来完成,您可以在其中停止MySQL服务.

2. 在"运行"窗口中使用"cmd"打开MS-DOS命令提示符.在里面它使用cd命令导航到你的MySQL bin文件夹,例如C:\ MySQL\bin.

3. 在命令提示符中执行以下命令: mysqld.exe -u root --skip-grant-tables

4. 保持当前的MS-DOS命令提示符,并打开一个新的MS-DOS命令提示符窗口.

5. 使用cd命令导航到您的MySQL bin文件夹,例如C:\ MySQL\bin.

6. 输入mysql并按Enter 键.

7. 您现在应该可以使用MySQL命令提示符.键入use mysql;以便我们切换到"mysql"数据库.

8. 执行以下命令更新密码:

   UPDATE user SET Password = PASSWORD('NEW_PASSWORD') WHERE User = 'root'; 
   

但是,您现在可以运行任何您希望的SQL命令.

关闭完第一个命令提示符后,键入exit;第二个命令提示符窗口以成功断开连接.您现在可以启动MySQL服务.

Answer 3

你的问题在这里：

2013-11-14 17:57:20 5180 [ERROR] InnoDB: .\ibdata1 can't be opened in read-write mode

ibdata1 文件存在一些问题 - 也许其权限已更改？也许其他进程已将其打开。它真的存在吗？

解决这个问题，也许其他一切都会水到渠成。
