Installation of wordpress on a local system

• Download WAMP server from http://www.wampserver.com/en/ and just click through the wizard to install it. After installation, start the WAMP server . We can see an icon in the system tray. Make sure that it is green (green means online and orange means offline).
• Click on that Icon and press phpmyadmin . Now phpmyadmin page will appear on the browser.Using the phpmyadmin, create a database for wordpress site.

WordPress installation error

error

Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the wordpress database.

• Are you sure it exists?
• Does the user root have permission to use the wordpress database?
• On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?

If you don't know how to set up a database you should contact your host. If all else fails you may find help at the WordPress Support Forums.
