その後、インタフェースを開き、mysql-u root mysqlコマンドでMysqlプログラムに入ります.
mysqlコマンドラインに、use mysqlと入力します.
次に、UPDATE user SET Password=PASWORD('newpassword')where USER='root';再起動すれば修正したパスワードでログインできます.

C.5.4.1.1. Resetting the Root Password: Windows Systems
On Windows, use the following procedure to reset the password for all MySQL
Log on to your system as Administrator.
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.
Create a text file containing the following statements. Replace the password with the password that you want to use.
Save the file. For this example, the file will be named
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.
Start the MySQL server with the special

C.5.4.1.1. Resetting the Root Password: Windows Systems
On Windows, use the following procedure to reset the password for all MySQL
root
accounts: Log on to your system as Administrator.
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.
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. Save the file. For this example, the file will be named
C:\mysql-init.txt
. 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.
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 5.5\bin\mysqld.exe"
--defaults-file="C:\\Program Files\\MySQL\\MySQL Server 5.5\\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. 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.
