Recently WordPress released WordPress 2.7 for wordpress.com blogs, now its the time to test it on our blogs. But testing WordPress 2.7 directly on running blog will be risky and may cause problems. Even if you are testing your own Plugin before releasing it, you can test it on your locally installed wordpress.
[Download WAMP server]
WAMP stands for Windows, Apache, MySQL and PHP.
1.Install WAMP on your system
2.Start Wamp Server. Go to Program Files >> Wamp Server >> start Wamp Server.
3.To create new databases Go to PHPmyadmin and create required databases for your wordpress.
4.Create new user for your wordpress and give proper privileges to that user using “Privileges” tab.
Most probably you need to give all privileges to this new user with the created database to handle wordpress.
5.Copy the wordpress files that you have downloaded in specific folder in WAMP server home. i.e. “DRIVE:\wamp\www\”.
6.Now edit the file “wp-config-sample.php” in your wordpress directory and fill up the proper database information like username, password, databasename in line number 3,4,5 and save the file as “wp-config.php”.
7. Open any browser enter “http://localhost/” and this will open your WAMP server page, install wordpress from “Your Projects” section.
After installing you can use your wordpress as your actual blog, you can import your online database from your online blog and can try everything on this locally installed wordpress.
In this way you can host wordpress on your personal computer, It almost feels like having your personal wordpress hosting.
