In this example, the file is C: \ mysql-init.txt. 4. Enter the doscommand prompt: Start Menu-> Run-> cmd. Assume that you have installed MySQL to C: \ mysql. If you install MySQL in another location, adjust the following commands. At the doscommand prompt, execute the command: C: \> C: \ mysql \ bin \ mysqld-nt -- init-file = C: \ mysql-init.txt when the server is started, run the "-- init-file" option (function: Read the SQL command from the specified file at startup) to change the root user password. When the server is successfully started, delete the C: \ mysql-init.txt. 5. Stop the MySQL server and restart it in normal mode.
