Login as root to the Unix-like (Unix, Linux or BSD) machine with the MySQL server.
Stop the MySQL server by using either of the following command
#/etc/init.d/mysql stop
Now you need to Start MySQL server without password
# mysqld_safe --skip-grant-tables &
Connect to mysql server using mysql client with the following command
# mysql -u root
Now you should be having mysql prompt
mysql>
Now you need to Setup new MySQL root user password
mysql> use mysql;
mysql> update user set password=PASSWORD(“newrootpassword”) where user=’root’;
mysql> flush privileges;
mysql> quit
Note: Replace newrootpassword with the new root password for MySQL server. Flush Privileges is needed to making the password change effect immediately.
Now you need to Stop MySQL Server using the following command
# /etc/init.d/mysql stop
Test Your New Mysql root password
First you need to start mysql server using the following command
# /etc/init.d/mysql start
# mysql -u root -p
Now it will prompt for root password and enter your new root password
