MySQL - Restore password There are two methods for restoring the MySQL root password: by a command window or UniController. The better method is to use UniController which is fully automated. The other method requires running two command windows and a certain amount of typing and editing.

Restore MySQL root user password using command window

To restore the MySQL root user password, the MySQL server requires restarting with "skip grant tables" option set. This bypasses any security, allowing access to the server. A new password is set and the grant tables updated. The following method uses two command windows and task manger.

Kill MySQL process

If the MySQL server is running, the process must first be stopped. Open windows task manager by pressing ctrl, alt and del keys together. In the window that opens, click on the Process tab (default); scroll up or down and locate the file mysqld1.exe. Right click on this and select End Process; click Yes to confirm kill process.

Note: If you have run multi-servers, the process name will differ. For example, mysqldX.exe, where X is a digit. Kill this process

Restart MySQL server skip grant

The MySQL server requires restarting from a command window with "skip grant tables" option set as follows:

Note: The path you installed The Uniform Server may be different; substitute your path as appropriate.

Start a command window: (Start > click on Run > type cmd click OK) Type the following lines into the command window: cd \ cd C:\UniServer\usr\local\mysql\bin mysqld1 --skip-grant-tables --user=root Note: Do not copy and paste! You must type it in. A flashing cursor indicates the server is running. Minimise this window (do not close it).

The dialogue in the command window looks similar to this:<r /> C:\Documents and Settings\mike>cd \ C:\> cd C:\UniServer\usr\local\mysql\bin C:\UniServer\usr\local\mysql\bin>mysqld1 --skip-grant-tables --user=root _

Set Password and Update grant tables

Start a second command window to set a new password (root) and update grant tables as follows:

Start a command window: (Start > click on Run > type cmd and click OK) Type following lines into the command window: cd \ cd C:\UniServer\usr\local\mysql\bin mysql USE mysql; UPDATE user SET password=password("root") WHERE user="root"; UPDATE user SET password=password("root") WHERE user="pma"; flush privileges; exit Finished. The dialogue in the command window looks similar to that on the right. Note: All three user root accounts have their passwords changed.
