MySQL Change Password
How do I MySQL root password under Linux, FreeBSD, OpenBSD and UNIX like operating system over ssl / telnet session ?
Setting up mysql password is one of the essential tasks.

By default root user is MySQL admin account. Please note that the Linux / UNIX login root account for your operating system and MySQL root are different. They are separate and have nothing to do with each other (indeed some admins remove the root account and setup admin as mysql super user).

mysqladmin command to change root password:

If you have never set a root password for MySQL, the sever doesn’t require a password at all for connecting as root to setup root password for first time, use the mysqladmin command at shell prompt as follows:

$ mysqladmin -u root password NEWPASSWORD

However, if you want to change (or update) a root passwod, then you need to use following command

$ mysqladmin -u root -p’oldpassword’ password newpass

For example, if old password abc, and set new password 123456, enter:

$ mysqladmin -u root -p’abc’ password ‘123456′

Change MySQL password for other user:

To change a normal user password you need to type (let us assume to would like to change password for ashish):

$ mysqladmin -u ashish -p oldpassword password newpass

Changing MySQL root user password using MySQL sql command:

This is the another method. MySQL stores username and passwords in user table inside MySQL database. You can directly update password using
the following method to update or change password for user ashish:

1) Loging to mysql server, type following command at shell prompt:
$ mysql -u root -p
2) Use mysql database (type command at mysql>prompt):
mysql> use mysql;
3) Change password for user ashish
mysql> update user set password=PASSWORD(“NEWPASSWORD”) where User=’ashish’;
4) Reload privileges:
mysql> flush privileges;
mysql> quit
$ mysql -u root -p
