In my client’s server the phpmyadmin not installed .
So client ask us to install that.
I refer this link to install phpmyadmin:
http://www.thewebhostinghero.com/tutorials/wamp-phpmyadmin.html
I downloaded and uploaded the phpmyadmin into server .
This is the server path where the phpmyadmin folder is installed:
/usr/local/apache2/htdocs/mysitefolder/phpMyAdmin
Then i created a folder in phhpmyadmin as config and set permission 777.
then i take the url in browser as:
http://mysite.com/phpMyAdmin/setup/index.php
I entered the mysql host ,usernmae,password and also changed the authentication type as config.
But the config.inc.php file not created in config folder.
EDIT:

You can copy the config.sample.inc.php file and rename it config.inc.php and do the changes in that file by hand.
