How to change MySql root password?

For every database, you should set the root or sa passwords to something other than the default, unless you want to get hacked. For mysql, the system administrator user is called root. You will use the mysqladmin utility from a command line to set the new password.

Syntax:

# mysqladmin -u root password “new_password”

# mysqladmin -u root -h host_name password “new_password”

Example:

# mysqladmin -u root password Pa55w0rD

# mysqladmin -u root -h localhost password linuxgEEks

You need to restart the database server after this change

# /etc/init.d/mysql restart
