How do I create a user account on MySQL database server?
When you try to access MySQL database server from client such as mysql or even programming language such as php or perl you need a user account. MySQL has sophisticated user management system that controls who can access server and from which client system. It uses special tables in mysql database. In order to create a new user account you need a MySQL root account password. You need to use the GRANT SQL command to set up the MySQL user account.

If you have never set a root password for MySQL server, the server does not require a password at all for connecting as root. To setup root password for first time, use mysqladmin command at shell prompt as follows:
$ mysqladmin -u root password NEWPASSWORDHowever, if you want to change (or update) a root password, then you need to use the following command:
$ mysqladmin -u root -p'oldpassword' password newpassFor example, If the old password is abc, you can set the new password to 123456, enter:
$ mysqladmin -u root -p’abc’ password ‘123456’
Note:123456 password is used for demonstration purpose only. You must select a strong password. It is an important protection to help you have safer MySQL database transactions.

How do I verify that the new password is working or not?
Use the following mysql command:
mysql -u root -p'123456' db-name-hereOR
mysql -u root -p'123456' -e 'show databases;'A note about changing MySQL password for other users
To change a normal user password you need to type the following command. In this example, change the password for nixcraft mysql user:
$ mysqladmin -u nixcraft -p'old-password' password new-passwordMethod #2: Changing MySQL root user password using the mysql command
This is an another method. MySQL stores username and passwords in user table inside MySQL database. You can directly update or change the password using the following method for user called nixcraft:
Login to mysql server, type the following command at shell prompt:
$ mysql -u root -pUse mysql database (type command at mysql> prompt):
mysql> use mysql;
Change password for user nixcraft, enter:
mysql> update user set password=PASSWORD(“NEWPASSWORD”) where User=’nixcraft’;
Finally, reload the privileges:
mysql> flush privileges; mysql> quit

This method is also useful with PHP, Python, or Perl scripting APIs.
