[Administrator]

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.

Please note that MySQL root user account is different from UNIX/Linux root login account. For example, the MySQL root user and the Linux/Unix root user are separate and have nothing to do with each other, even though the username is the same in each case.

Setup a root user password

To setup root password for first time, use mysqladmin command at shell prompt as follows:

$ mysqladmin -u root password NEWPASSWO

If you want to change or update a root user password, then you need to use the following command:

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