Sometimes, you may need to reset MySQL root password without existing root password on your web hosting server. You can reset the password by following the below steps:
 Stop the MySQL service from the server.
 Start the MySQL (mysqld) server/daemon process with the –skip-grant-tables option so that it will not prompt for password.
 Connect to mysql server as the root user. You can connect with GUI tool or from SSH or command line.
 Update MySQL root password using the following query:
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
Flush the privileges using the following query:
 Exit and restart the MySQL service.
For Linux servers, following are the complete steps with commands:
 Stop MySQL service:
# /etc/init.d/mysql stop
 Start MySQL with –skip-grant-tables:
# mysqld_safe --skip-grant-tables
 Connect to MySQL server:
mysql -u root
 Set new MySQL root user password:
mysql> use mysql; mysql> update user set password=PASSWORD("MyNewPass") where User='root'; mysql> flush privileges; mysql> quit
 Stop and start MySQL service:
# /etc/init.d/mysql stop # /etc/init.d/mysql start
That’s it. Now, you should be able to access MySQL server using the root password specified in steps 4.
