You can recover MySQL database server password with following five easy steps.
Step # 1: Stop the MySQL server process.
Step # 2: Start the MySQL (mysqld) server/daemon process with the –skip-grant-tables option so that it will not prompt for password.
Step # 3: Connect to mysql server as the root user.
Step # 4: Setup new mysql root account password i.e. reset mysql password.
Step # 5: Exit and restart the MySQL server.
Here are commands you need to type for each step (login as the root user):
Step # 1 : Stop mysql service
