mysqladmin -u root -pcurrentpassword password newpassword

2. To Setup a root password, if a password was not setup

mysqladmin -u root password NEWPASSWORD

mysql –u root –p

mysql> use mysql;

Step3. Change password.

mysql> update user set password=PASSWORD("newpass") where User='root';

Step4. Reload privileges

mysql> flush privileges;
