How to reset mysql root password? (8 个回答)

已关闭 6 年前。

我使用安装程序安装了 MySQL 5.6。我忘记了密码。所以我按照一些例子来重置 root 的 root pwd。我给出的命令是这样的:

C:\Windows\system32>"C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld.exe" --i
nit-file="c:\\new folder\mysql-init.txt" --explicit_defaults_for_timestamp=true

命令提示符静默返回，而不启动 Mysql。我实际上需要重置密码。请指出我的错误。如果我做错了什么，请告诉我!!

在 Windows 上，使用以下过程重置所有 MySQL root 帐户的密码:

 1. Log on to your system as Administrator. 
 2.  Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list and stop it.

 If your server is not running as a service, you may need to use the Task Manager to force it to stop. 

 3.  Create a text file containing the following statements. Replace the password with the password that you want to use.

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

 Write the UPDATE and FLUSH statements each on a single line. The UPDATE statement resets the password for all root accounts, and the FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change. 

 4. Save the file. For this example, the file will be named C:\mysql-init.txt. 

 5. Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run. 

 6.  Start the MySQL server with the special --init-file option (notice that the backslash in the option value is doubled):

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

 If you installed MySQL to a location other than C:\mysql, adjust the command accordingly.

 The server executes the contents of the file named by the --init-file option at startup, changing each root account password.

 You can also add the --console option to the command if you want server output to appear in the console window rather than in a log file.

 If you installed MySQL using the MySQL Installation Wizard, you may need to specify a --defaults-file option:

 C:\> "C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqld.exe"
         --defaults-file="C:\\Program Files\\MySQL\\MySQL Server 5.6\\my.ini"
         --init-file=C:\\mysql-init.txt

 The appropriate --defaults-file setting can be found using the Services Manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list, right-click it, and choose the Properties option. The Path to executable field contains the --defaults-file setting. 

 7. After the server has started successfully, delete C:\mysql-init.txt. 





You should now be able to connect to the MySQL server as root using the new password. Stop
the MySQL server, then restart it in normal mode again. If you run the server as a 
service, start it from the Windows Services window. If you start the server manually,
use whatever command you normally use.
