Use the following procedure for resetting the password for
any MySQL root
accounts on Windows:
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:
Start Menu -> Control Panel -> Administrative Tools -> Services
Then 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 and place the following statements in it. Replace the password with the password that you want to use.
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root'; FLUSH PRIVILEGES;
The UPDATE
and
FLUSH
statements each
must be written on a single line. The
UPDATE
statement resets
the password for all existing root
accounts, and the FLUSH
statement tells the server to reload the grant tables
into memory.
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:
Start Menu -> Run -> cmd
Start the MySQL server with the special
--init-file
option:
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 5.4\bin\mysqld.exe"
--defaults-file="C:\Program Files\MySQL\MySQL Server 5.4\my.ini"
--init-file=C:\mysql-init.txt
The appropriate
--defaults-file
setting
can be found using the Services Manager:
Start Menu -> Control Panel -> Administrative Tools -> Services
Find the MySQL service in the list, right-click on 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
.
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.
You should now be able to connect to MySQL as
root
using the new password.
